-2 (3+5y-10) = 34
Step 1) -6-10y+20=34
Step 2) -10y+20=40
Step 3) -10y=20
Step 4) y = -2
Answer is -2
Answer:
48
Step-by-step explanation:
3 times 13 (john's age) = 39
39 + 9 = 48 (nine years older than 3 times (39) so you add 9)
Therefore, Tim is 48.
Answer:2600
Step-by-step explanation: 25%=1/4
650×4=2600
So to find a cylinder's volume, you do πr^2*h = volumeSo we can fill in a few of the elements.3.14 * 2.5 ^2 * h = 170And then we can continue to simplify it.3.14 * 6.25 * h = 17019.625 * h = 170And then to find h,170/19.625 = about 8.66
Answer: 0.5
Step-by-step explanation:
Add 3/16 to both sides to isolate the variable on one side. Then the equation should be x=8/16 which is 0.5.
