Answer: gotta scroll down sry

Step-by-step explanation:

First set up equations with variables that show the information you have:
c = chocolate // g = gummy // h = hard candy

178 = c + g + h

h = c + 15

g = 2c - 5

Then, solve all the equations for a number:

178 = c + g + h (leave as is)

15 = -c + h (subtract 'c' from the original equation's right side and switch the sides of the equation)

-5 = -2c + g (subtract '2c' from the original equation's right side and switch the side of the equation)

Then, line up all the variables and subtract the top equation by the lower two:

178 = c + g + h

15 = -c + 0g + h

-5 = -2c + g + 0h

---------------------------

168 = 4c + 0g + 0h >>>> 168 = 4c

Solve for 'c' and plug it into the other equations to find 'h' and 'g':

168/4 = 4c/4

42 = c

15 = -(42) + h                    -5 = -2(42) +g

57 = h                                79 = g

Add all the numbers together to double-check:

42 + 57 + 79 = 178

chocolates = 42

gummies = 79

hard candies = 57

Hey! Your answer would be A. (1/5)(-20)

Answer:

a. 66c per oz of cheese bought

b. 66x

Step-by-step explanation:

a. Looking at the graph you can see that the price of 1 oz of cheese is 66 cents. As the graph is a straight line it is seen that the price rises by 66 cents per oz bought.

b. We use the answer of 66 cents per oz of cheese and change the cents out for x, to be able to a y = mx + b equation and since it starts at 0 the b = 0.

Answer:

D

Step-by-step explanation:

If you match up what it says you get it, so -2 1/4 is equal to so = then 4/5 times a number, it is not specific on the number so it is x and then you add -2 which is the same as subtracting 2.

Answer:

Step-by-step explanation:

reason 1:

opening of brackets to solve the expression

reason 2:

in multiplication order is followed i.e. the number always lead the variable in the expression

reason 3:

for clarification brackets are added to multiply like terms i.e. numbers with numbers and variable with the variable

reason 4:

the solved and simplified expression is delivered as a result

Answer:

Step-by-step explanation:

First, you have to solve it with parenthesis, where the answer is one, then multiply them by 6= 6. The answer is 4.

Answer:

673

Step-by-step explanation:

okay so uh this is my way and the answer works so like yea teachers dont show like this but ii figured this works

okay so

85/100 = 572/?

so if you divide 85 by 85 its gonna equal 1 and 1 times 100 is gonna be 100

useing the same concept, it should be the same with 572 , but instead of divideing by 572, divide by 85.

basically 572/85

okay now thats gonna give you 6.72941176471 thats vasically 1% of the population.

so multiply 6.72941176471 * 100

so now you have

672.941176471 and you can round this to 673 kids.

and you know its right since 85% of 673 is 572.05 and you can sound to 572

Answer:

673 students

Step-by-step explanation:

Divide the number of students who applied and the decimal of the percentage they represent.

85% = 85/100 = 0.85

572/.85 = 673

Hope this helps

Answer:

  empirical rule: 81.5%

  table or calculator: 81.9%

Step-by-step explanation:

The lower limit of the life range of interest has a z-score of ...

  z = (x -μ)/σ = (20,000 -30,000)/5,000 = -2

The upper limit has a z-score of ...

  z = (35,000 -30,000)/5,000 = 1

Empirical rule solution

The empirical rule tells you that 95% of the distribution lies within 2 standard deviations of the mean, so (100% -95%)/2 = 2.5% lie below z = -2. It also tells you 68% lie within 1 standard deviation of the mean, so (100% -68%)/2 = 16% lie above z = 1.

The fraction that lies within -2 to 1 standard deviations of the means is thus ...

  (100% -2.5% -16%) = 81.5%

The probability the tire has a life in the desired range is about 81.5%.

__

Calculator solution

A probability calculator for the Normal distribution tells you that ...

  P(-2 < z < 1) ≈ 0.8185946

The probability the tire has a life in the desired range is about 81.9%.

Answer:

According to Wolfram, "sided polygon in which the sides are all the same length and are symmetrically placed about a common center."

According to TheSchoolRun, "A polygon is a flat, two-dimensional (2D) shape with straight sides that is fully closed (all the sides are joined up). The sides must be straight. Polygons may have any number of sides. A polygon. A shape with curved sides is not a polygon."

So, yes, that is indeed a polygon.

Answer:

Audrey's shape is not a regular polygon.

Step-by-step explanation:

We know what a polygon is, but there are two types. Regular and irregular. A regular polygon's sides are all equal. An irregular polygon's sides are not all equal.

In this case, Audrey's shape is an irregular polygon. 3 of the lines are of unequal length to the rest which makes it irregular.

Answer:

The monthly cost (in dollars) of a long-distance phone plan is a linear function, which means that the cost is proportional to the total calling time (in minutes). To calculate the monthly cost for 66 minutes of calls, we can use the following equation:

Cost = m * Minutes + b

Where m is the slope of the line, and b is the y-intercept. To find m and b, we can use the two given points: (51, $17.32) and (79, $20.96).

Using the slope formula: m = (20.96 - 17.32)/(79 - 51) = 0.44

We can then use the y-intercept formula: b = 17.32 - 0.44*51 = -4.64

Now we can plug in 66 for Minutes and solve for Cost: Cost = 0.44*66 - 4.64 = $17.12

Therefore, the monthly cost for 66 minutes of calls is $17.12.

Answer:

4

Step-by-step explanation:

The mean is the average.

1. Add up all the numbers

8+2+5+5+4+2+2= 28

2. Divide by the total numbers you have

28/7= 4

Answer: 4

Step-by-step explanation: 4 is the answer because to find the mean of a set of numbers first, you have to add all the numers up and then divide by how many numbers there are in the set.

Answer:

15.6 in.

Step-by-step explanation:

If the volume of the box is scaled down by a factor of 1/10, that means you just have to move the decimal over to the left by one place value, making the new volume 15.6 in because behind the 156 there's an invisible decimal in case you need it.

Answer:

A. This problem would best be solved using a tree diagram.

B. In order to solve it, you would construct a tree with the first soup choices growing into the other options. Then, after listing every alternative, you could either add them all up to obtain your answer or you could just use the formula 2*4*2=16, which would result in 16 possibilities.

Answer:

The decimal 5.8 is read as 5 and 8 tenths. So, it is written as a mixed number 5810.

In simplest form 5810=545.

The same number is converted into an improper fraction as follows. 5 × 5 + 4 = 29. This the numerator of the improper fraction and 5 is the denominator. So, 545=295. Show Answer.
