Answer:
v = -5, t = -13. , d = -12
Step-by-step explanation:
29) 3v - 9v = 30
Simplifying gives us -6v = 30. Then dividing both sides by -6 reaches our answer of v = -5.
30)12t - 8t = -52
Simplifying gives us 4t = -52. We can divide both sides by 4 to reach a conclusion that t = -13.
31) -8d - 5d + 7d = 72
Simplifying gives us -6d = 72. We can then divide both sides by -6. In doing so, we can achieve our answer that d = -12.
Add all the integers together and then divide by 10 because that’s how many numbers you’re adding.
Answer:
area of circle=πr²=3.14×5²=78.5unit²
64+(2x)=35(x-1)
expand
64+2x=35x-35
minus 2x from both sides
64=33x-35
add 35 to both sides
99=33x
divide both sides by 33
3=x
the number is 3
Answer:
(x+1)²= 49, the answer is B
Step-by-step explanation:
x² + 2x = 48
x² + 2x + (2/2)² - (2/2)²= 48 --[what we are trying to do is to complete a square by adding (2/2)² - (2/2)²]
(x+1)²= 49, the answer is B
