6x = 52 − 2y 5x + 7y = 70 Question 1 What is the first step when solving the given system by the elimination method?
The solution of the equations 6x = 52 − 2y and 5x + 7y = 70 by elimination method will be (7, 5).
What is the solution to the equation?In other words, the collection of all feasible values for the parameters that satisfy the specified mathematical equation is the convenient storage of the bunch of equations.
The equations are given below.
6x = 52 - 2y
6x + 2y = 52
3x + y = 26 ...1
5x + 7y = 70
(5/7)x + y = 10 ...2
Subtraction equation 2 from equation 1, then we have
3x - (5/7)x = 26 - 10
(16/7)x = 16
x = 7
Then the value of 'y' is given as,
3(7) + y = 26
21 + y = 26
y = 5
The solution of the equations 6x = 52 − 2y and 5x + 7y = 70 by elimination method will be (7, 5).

IGNORE THE BOTTOM ONE PLEASE HELP
Answer:
see explanation
Step-by-step explanation:
∠ A and ∠ FCE are corresponding angles and are congruent , then
∠ A = 150°
∠ FCE and ∠ C are vertically opposite angles and are congruent , then
∠ C = 150°
∠ FCE and ∠ ECB are adjacent angles on a straight line and sum to 180°
∠ ECB = 180° - ∠FCE = 180° - 150° = 30°
∠ E = 180° - (30 + 45)° ← sum of angles in a triangle
∠ E = 180° - 75° = 105°
∠ CBE and ∠ D are same- side interior angles and sum to 180° , then
∠ D = 180° - 45° = 135°
What is the multiplier for a 30% decrease. *
Answer:
0.7
Step-by-step explanation:
Let the number to be decreased be x. To decrease x by 30 %, the result will be
= x - 30% * x
= x - 0.3x
= 0.7x
From above, the result is 0.7 multiplied by the number to be reduced. Hence the multiplier is 0.7

Andre and Jillian were shopping at the same grocery store for bottles of sports drinks for their kickball teams. Andre bought 3
packs of bottled drinks, plus 11 single bottles. Jillian purchased 5 packs, plus 3 singles. Andre and Jillian discovered that they
had purchased the same number of bottles. How many bottles were in each of the packs? (All of the packs have the same
number of bottles.)
Answer:
x = 4
Step-by-step explanation:
The equation comes out to be:
3x + 11 = 5x + 3
Move the variables to the left-hand side and change its sign
And move the constant to the right-hand side and change its sign:
3x - 5x = 3 - 11
Combine like terms to get:
-2x = -8
Isolate x by dividing -2 on both sides:
-2x/-2 = -8/-2
x = 4
The number of bottles in the pack is 4.
Expressions that represent the total bottles boughtThe expression that can be used to represent the number of bottles bought by Andre is 3p + 11.
The expression that can be used to represent the number of bottles bought by Jillian is 5p + 3
Where:
p = number of bottles in the packs bought
Determining the number of bottles in the packIf both Andre and Jillian have the same number of bottles, their expressions would be equal
3p + 11 = 5p + 3
In order to determine the value of p, take the following steps:
Combine similar terms
5p - 3p = 11 - 3
2p = 8
Divide both sides of the equation by 2
p = 4

Ross needs to buy a countertop for a laundry room. He calculated the area to be 12 square feet. The actual area is 11.8 square feet. What is Ross's percentage error? a.1.02% b.1.69% c.20% d.98%
Answer:
b. 1.69
Step-by-step explanation:
So to solve this problem we need to simply find the percentage increase from 11.8 to 12 =>
to solve this we would do 12 - 11.8 = 0.2 --> 0.2 is our "difference in the increase" -->
now we divide this by our amt. which is 11.8 --> 0.2/11.8 = approx. 0.0169
--> finally multiply that by 100 which is simply moving the decimal places 2 places right giving us the final answer of 1.69
Hope this helps!
Answer:
B. 1.69%
Step-by-step explanation:
If Ross calculated the countertop for a laundry room to be 12 square feet but turns out to be actually 11.8 square feet, we need to find out how much percentage error Ross has made!
In order to solve this question,
1) We need to create proportions:
Ross' calculations x
______________ = _________
actual area 100
x represents the percentage error.
100 is the total percentage.
2) Now we plug in the numbers:
We plug in 12 for Ross' calculations. We plug in 11.8 for the actual area. So, it will look like this:
12 x
______ = _______
11.8 100
3) Time for cross multiplication:
12 times 100 is 1,200
11.8 times x is 11.8x
So,
1,200 = 11.8x
4) Now we divide:
1,200 divided by 11.8 equals to 101.69 %
5) We are not done! We still have to subtract:
101.69
-100.00
_______
1.69
Finished!!
Our answer is 1.69%, which is B.

The emplοyee's percent is 100% decreased by the emplοyer's percent.
100%−73%=27%
Based on the information you provided, Rubina Shaw's annual premium for the HMO plan is $11,473. Her employer pays 73 percent of this premium, so Rubina's portion of the premium would be:
27% × $11,473 = 0.27 × $11,473 = $3,097.71
The emplοyee's annual cοntributiοn is the prοduct οf the emplοyee's percent and the tοtal premium.
The emplοyee's mοnthly deductiοn is the emplοyee's annual cοntributiοn divided by the number οf mοnths in a year.
$3,097.71 ÷ 12

2. center (5, -6), radius 4
Answer:
(x - 5)² + (y + 6)² = 16
Step-by-step explanation:
assuming you require the equation of the circle
the equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k ) are the coordinates of the centre and r is the radius
here (h, k ) = (5, - 6 ) and r = 4 , then
(x - 5)² + (y - (- 6) )² = 4² , that is
(x - 5)² + (y + 6)² = 16

This table shows the ratio of the number of red beans to the total number of beans.
A 2-column table has 2 rows. Column 1 is labeled Total with entries 30, and 15. Column 2 is labeled Red with entries 20, and 10.
Which ratios are equivalent to 30:20? Check all that apply.
40:30
10:0
3:2
the answer is C and D
The ratio which is equivalent to 30:20 is option C, 3:2.
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
\(\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}\)
where is a common factor (not 1)? This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly canceled from both the numerator and the denominator.
Thus, a = px, b = qx
We have given that a 2-column table has 2 rows. Column 1 is labeled
The Total with entries 30, and 15. Column 2 is labeled Red with entries 20, and 10.
Given ratio is 30:20

Last year and investor purchased 115 shares of stock A at $90 per share
The difference in overall loss or gain between sell at the current day's high price or low price is found tp be the difference in overall gain as $280.10
The third option is correct.
How do we calculate?For stock A:High price value: 115 shares * $105.19 per share = $12,084.85
Low price value: 115 shares * $103.25 per share = $11,858.75
For stock B:High price value: 30 shares * $145.18 per share = $4,355.40
Low price value: 30 shares * $143.28 per share = $4,298.40
The overall value at high price:
$12,084.85 + $4,355.40
= $16,440.25
The overall value at low price:
$11,858.75 + $4,298.40
= $16,157.15
In conclusion, the difference in overall gain or loss:
$16,440.25 - $16,157.15 = $280.10

11. The value of x is 8
Calculating the value of xFrom the question, we are to determine the value of x in the given diagram.
8.
2x + 12 = 5x - 15
Collect like terms
12 + 15 = 5x - 2x
27 = 3x
3x = 27
Divide both sides by 3
3x/x = 27/3
x = 9
9.
8x - 63 = 4x - 27
Collect like terms
8x - 4x = -27 + 63
4x = 36
Divide both sides by 4
4x/4 = 36/4
x = 9
10.
(3x - 18)° = 90°
3x - 18 = 90
Add 18 to both sides
3x - 18 + 18 = 90 + 18
3x = 108
Divide both sides by 3
3x/3 = 108/3
x = 36
11.
Since the angles are complementary, we can write that
(3x)° + (8x + 2)° = 90°
3x + 8x + 2 = 90
11x + 2 = 90
Subtract 2 from both sides of the equation
11x + 2 - 2 = 90 -2
11x = 88
Divide both sides by 11
11x/11 = 88/11
x = 8
Hence, the value of x is 8
