Answer: C: 4/$7.76=13/x

Step-by-step explanation:

Set them proportionally equal. Glue stick numbers on top, and the cost for them below. Since you do not know the cost of 13 glue sticks, x, representing the cost of the glue sticks goes on the bottom. then, you have

4/$7.76=13/x

  4  = 13

7.76 = x

You can multiply 13*$7.76, which equals $100.88.

Then, divide $100.88 by 4. You should get $25.22.

Therefore, 13 glue sticks equal $25.22.

ioda

Answer:

3

clients who did Plan A and

2

who did Plan B. On Tuesday there were

8

clients who did Plan A and

4

who did Plan B. Linda trained her Monday clients for a total of

4

hours and her Tuesday clients for a total of

9

hours.

Step-by-step explanation:

let x equal the number of hours for each plan A workout.

let y equal the number of hours for each plan B workout.

on monday, there were 3 clients who did plan A workout and 2 clients who did plan B workout for a total of 4 hours.

the formula for monday becomes 3x + 2y = 4

on tuesday, there were 8 clients who did plan A workout and 4 clients who did plan B workout for a total of 9 hours.

the formula for tuesday becomes 8x + 4y = 9

you have to solve these 2 equations simultaneously.

they are:

3x + 2y = 4

8x + 4y = 9

multiply both sides of the first equation by 2 and leave the second equation as is to get:

6x + 4y = 8

8x + 4y = 9

Is the expression below completely factored? If not, complete the factorization.
Ket [755]

Answer:

A) No, because the greatest common factor is 8y?, and the completely factored form is 8y2(4y2 - 6y + 3).

Step-by-step explanation:

Considering the expression

4y(8y3 – 12y2 + 6y)

From the elements in the parenthesis, 2 and y can still be factored out such that what will be left of each element

8y3/2y = 4y2

12y2/2y = 6y

6y/2y = 3

Hence

4y(8y3 – 12y2 + 6y) = 4y*2y(4y2 - 6y +3)

= 8y2(4y2 - 6y + 3)
