1.7,5-1,5=6
2.10-11=-1
3.6×-1=-6
4.-6+2=-4
Answer:
<em>The expression is equal to 22</em>
Step-by-step explanation:
<u>Expression Evaluation</u>
We are given the expression
10 + 2p - 3r
And it's required to evaluate it when p=3 and r=2. This means we have to replace the letter for the value assigned to them, as follows:
10 + 2*3 - 3*(-2) = 10 + 6 - (-6)
= 10 + 6 + 6
= 22
The expression is equal to 22
An infinite amount seeing as you can have infinite of each number
1. Let the first integer be represented by: 2k
the second integer by: 2(k+1)
the third integer by: 2(k+2)
and the fourth by: 2(k+3)
Then, 2k + 2(k+2) = 2(k+3) - 6
2k + 2k + 4 = 2k + 6 - 6
4k + 4 = 2k
4 = -2k
-2 = k
Answer: -4, -2, 0, 2

2. Let the first integer be represented by: 2k+1
the second integer by: 2k+3
the third integer by: 2k+5
and the fourth by: 2k+7
Then, 2k+7 = (2k+1) + (2k+3) + (2k+5) + 2
2k + 7 = 6k + 11
-4 = 4k
-1 = k
Answer: -1, 1, 3, 5
