1 answer:
spin [16.1K]2 years ago
7 0

Answer:

For the first test the score was 89 and on the second test it was 96

Step-by-step explanation:

To find the answer we make the situation into an algebraic expression.

x + (x  - 7) = 185 \\ 2x  -  7 = 185 \\ 2x = 185  + 7 \\ 2x = 192 \\  \frac{2x}{2}  =  \frac{192}{2}

192 divided by 2 is 96; hence

x = 96 \\ x + (x - 7) = 185 \\ 96 + (96 - 7) = 185 \\ 96  + 89 = 185

goblinko [34]

Answer:

30-3p and 3(10-p)

Step-by-step explanation:

We know that he starts with 30 candy bars.

Now, we know that he has p friends, and that each friend received 3 candy bars.

Therefore, the answer is 30-3p

However, if you divide 30-3p by 10, you get the expression 3(10-p)

Thus, either answer is acceptable.

patriot [66]

Answer:

I got 32.

Step-by-step explanation:

I used the Pythagorean theorem to find the lengths of the width and length. The length between (-1, 4) and (3, 3) was approximately 4 in. The distance between (-1, 4) and (-3, -4) was approximately 8 in. I then used those numbers to find the perimeter ((2*4)+(2*8))
