Mr. Suarez joined a gym to lose weight. After 3 weeks of membership, he weighed 189 pounds. when he had been a member for 12 week he weighed 162 pounds
please hurry in need this turend in by 6:30
Answers
That’s 3 pounds a week
That means before he got the gym membership he weighed 198 pounds
He lost a total of 36 pounds over 12 weeks
The equation that represents weight loss in a particular week will be y = -3x + 198.
What is a linear equation?A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
Mr. Suarez joined a rec center to shed pounds. Following 3 weeks of participation, he weighed 189 pounds. at the point when he had been a part for a multi-week he weighed 162 pounds.
Let 'x' be the number of weeks and 'y' be the weight remaining. Then we have
189 = 3m + c
162 = 12m + c
From equations 1 and 2, then we have
189 - 162 = -12m + 3m
9m = -27
m = -3
Then the value of c is given as,
162 = 12(-3) + c
162 = -36 + c
c = 198
The equation that represents weight loss in a particular week will be y = -3x + 198.

Write your answer as a FRACTION
Answers
Answer:
\(\frac{1}{5}\)
Step-by-step explanation:
Assuming a total of ten students were asked, \(\frac{2}{10}\) chose football and \(\frac{8}{10}\) chose other sports. \(\frac{2}{10}\) simplified is \(\frac{1}{5}\), so that's the experimental chance that the next student favors football.
The experimental probability that the next student Meg talks to will pick football is 1/5.
What is Probability?Probability is simply the possibility of getting an event. Or in other words, we are predicting the chance of getting an event.
The value of probability will be always in the range from 0 to 1.
Given that,
Meg surveyed some students at her school about their favorite professional sports. Of the students surveyed, 2 said football was their favorite sport, while 8 of the students had other favorite sports.
Total number of students surveyed = 8 + 2 = 10
Of the 10 students, 2 said football as their favorite sport.
Probability that a student picks football = 2/10 = 1/5
Hence the probability that the next student picks football is 1/5.

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666...

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Kelly wants to make a fruit salad made up of bananas, apples, and peaches. She wants to mix one part apples, 2 parts peaches, and 3 parts bananas. Bananas cost $2.00 per pound, apples cost $4.00 per pound, and peaches cost $5.00 per pound. Kelly only has $10.00, and will spend it all on fruit salad. Write an equation and use this equation to determine how many pounds of fruit salad he can make.
Answers
Step-by-step explanation:
If x is the pounds of apples, 2x is pounds of peaches, and 3x is pounds of bananas, then the total cost is:
4(x) + 5(2x) + 2(3x) = 10
4x + 10x + 6x = 10
20x = 10
x = 0.5
Kelly buys 0.5 pounds of apples, 1 pound of peaches, and 1.5 pounds of bananas, for a total of 3 pounds of fruit.

∠6 and ∠8 are ___ angles. (same options as first one)
∠1 and ∠5 are ___ angles. (same options as first one)
Answers
Answer:
∠1 and ∠2 are supplementary angles.
∠6 and ∠8 are vertical angles
∠1 and ∠5 are corresponding angles.
Step-by-step explanation:
∠1 and ∠2 lie on a straight line which will always add up to 180 degrees or supplementary.
∠6 and ∠8 lie opposite each other on the transversal (intersecting line) and are equal.
<1 and <2 are Supplementary angles
<1 and <5 are Corresponding angles
<6 and <8 are Vertical angles
Given that d II e
when a transversal intersects two parallel lines the following conditions are true:
Supplementary angles are those angles when the sum of two angles is equal to 180 degrees. Since <1 and <2 are on either side of the transversal their sum is equal to 180 degrees hence why it's a supplementary angle.
Vertical angles form 4 angles when a line intersects them and the two angles are opposite to each other. In this case <6 and <8 are opposite each other hence why they are vertical angles.
Corresponding angles are the angles that are in the same position on each of the parallel lines and on the same side of the transversal. In this case both <1 and <5 are on the same side of the transversal on each of the parallel lines hence why they are corresponding angles

Mila and Ben use red and orange beads to make braclets with 60 beads each. Mila uses 2 red beads for every 3 orange beads. Ben uses 5 red beads for every 7 orange beads. Who uses more orange beads?
Answers
Answer: Mila
Step-by-step explanation: First, you have to find the amount of orange beads Mila uses. First, you want to multiply 2 and 3 by 12, which results in 24 and 36. once you add them together, you get the total of 60. Next, you have to find the number of orange beads Ben uses. In order to solve the problem, you multiply 5 and 7 by 5, and the resulting numbers are 25 and 35. Once you add them together, you get a total of 60. Lastly, you can set up an equation, which results in 36 > 35. Therefore, Mia used more orange beads than Ben did. Mia > Ben
