Molly and Arthur are taking their daughter Ginny on a roller coaster ride. For safety, they need to find their total weight before getting into the same car. Molly’s weight is MMM kilograms, Arthur’s weight is AAA kilograms, and Ginny’s weight is GGG kilograms.The expression (M+A)+G(M+A)+Gleft parenthesis, M, plus, A, right parenthesis, plus, G describes their total weight. We can also use the expression A+(G+M)A+(G+M)A, plus, left parenthesis, G, plus, M, right parenthesis to represent the same quantity.

Match each amount in the situation with the expression that represents it.

For reference:

Molly is a female and an adult.

Arthur is a male and an adult.

Ginny is a female and a child.

Answer 1
Answer:

Answer:

This is weirdly written, but let's try to solve it:

M is the mass of Molly

A is the mass of Arthur

G is the mass of Ginny.

We can represent the weight as:

(M + A) + G

or as:

A + (G + M)

the first situation shows that Molly and Arthur are weight together (this is why their weight is shown as only one), and then they weight Ginny alone.

The second situation shows that Arthur is weight alone, and Ginny and Molly are weight together (this is why their weight is written as only one)

Solve the equation for x:3x – 17 = 9x + 7

A x = 4
B x = –4
C x = 610
D x = −610

Answers

3x - 17 = 9x + 7

Rearrange on same sides
-17 - 7 = 9x - 3x
-24 = 6x

Divide by 6 on either sides to isolate 6
-(24)/(6) = (6x)/(6)
6 and 6 cancels out

i just got the question correct

Every week Sarah collects a few pounds of cans to recycle. The graph below shows the total number of pounds of cans (y) that Sarah collected in a certain amount of time (x), in weeks: A graph titled Can Recycling is shown with labels in x axis and y axis as Number of Weeks and Amount of Cans Collected in pounds, respectively. The values on the x axis are from 0 to 5 at increments of 1, and the values on the y axis are from 0 to 100 with increments of 20. Dots are made at 0, 20 and 1, 40 and 2, 60 and 3, 80 and 4, 100. A straight line joins the ordered pairs 0, 20 and 4,100.

What would most likely be the total amount of cans, in pounds, Sarah would collect in 10 weeks?

200
220
320
420

Answers

Answer:

The amount of cans, in pounds,Sarah would collect in 10 weeks is:

                                  220

Step-by-step explanation:

The x and y value as according to the information are as follows:

        x (Number of weeks)        y(Amount of cans collected)

                 0                                         20

                  1                                          40

                  2                                         60

                  3                                         80

                  4                                        100

Hence, we see that with each increasing weeks the number of cans collected increased by a constant rate i.e. 20

The equation that represent these points are:

                      y=20(x+1)

Now we have to calculate the value of y when x=10

when x=10 we have:

         y=20(10+1)

         y=20×11

         y=220

Hence, the answer is:  220

Answer:

the answer is 220 I got it right on flvs

Step-by-step explanation:

y=20x+20

y=20(10)+20

y=200+20

y=220
