Answer: 6a^2 +16

Step-by-step explanation: Combining like terms (7 a^2 -a^2) you get 6a^2. That’s as much as it can be simplified without knowing the values of x because there are no more like terms. Hope this helps :)

Answer:

1.) X = 7 and Y = 5

2.) 5 streamers

Step-by-step explanation:

According to the question, you are given the inequality equation of

2.5x + 3.5y < = 35

Since the equation is less than or equal to, than means that the equation can be 2.5x + 3.5y = 35

According to the graph,

X = 14 and Y = 10

Substitute both into the equation if it will not exceed 35

2.5(14) + 3.5(10) = 35

35 + 35 = 70. This is wrong.

Take the half value of both x and y and substitute again

X = 7 and Y = 5

2.5(7) + 3.5(5)

17.5 + 17.5 = 35

Therefore, she can buy 7 helium - filled balloons and 5 streamers

2.) If Julie buy 6 ballons, substitute x for 6 in the inequality equation to find y

2.5(6) + 3.5y < = 35

Open the bracket

15 + 3.5y < = 35

Collect the like terms

3.5y <= 35 - 15

3.5y <= 20

Make y the subject of formula

Y <= 20/3.5

Y < = 5.7

We can therefore conclude that she can buy 5 streamers. Or 5 1/2 if possible.

Jess was babysitting 4 kids. She brought candy as their reward for being good. Jess kept 10
Dmitry_Shevchenko [17]

Answer:

6 pieces

Step-by-step explanation:

The equation is

4x + 10 = 34

If she had 34 pieces, and kept 10, you can subtract the 10 because she divided the rest of the remaining candy after taking 10.

You now have 24 pieces left to divide, which she does between 4 kids, so you divide it by 4.
