Answer:
x = 19
Step-by-step explanation:
These angles are supplementary angles which mean they add up to 180:
8x - 7 + x + 16 = 180
9x + 9 = 180
9x = 180 - 9
9x = 171
x = 171/9
x = 19
Answer:
n = -2
Step-by-step explanation:
Step 1: Write equation
3 = -1.5n
Step 2: Divide both sides by -1.5
n = -2
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
3 = -1.5(-2)
3 = 3
The next number will be 625
Im guess that says the first # is half the second #
Since one # is 2 times the other, if we make the smaller number x and the bigger # 2x, the sum of them is 3x. So...
3030=3x
1010=x
so one number is 1010 and the other is 2020
