Answer:
14
Step-by-step explanation:
2v - 7 = 9
Add 7 to both sides
2v = 16
Divide both sides by 2
v = 8
Plug it into 3v - 10
3v - 10 =
3(8) - 10 =
24 - 10 =
14
Answer:
Step-by-step explanation:
63 - (-4) = 63 + 4 = 67 <== a difference of 67
or think of it this way..
if its at 63, u subtract 63 just to get to 0....but then u have to subtract 4 more to get to -4......making a difference of 67
Area = (a+b/2)h
a and b means base
(3+8/2)x7=38.5 I’m not very sure about my answer sorry if it’s wrong
Since there are no numbers, i will assume that the length of recess is 1 minute, or x. if social studies is 4 more than 2 times the length of recess, we can use the equation x*2+4 to solve the problem. the end result will be 6 minutes. Social studies is 6 minutes longer than recess
Y= 3/5x-2 if you are solving for y. You first subtract the 10 so it would be 3x-10=5y then divide everything by 5. Giving you a slope of 3/5. And 10/5=2 . So Y=3/5x-2
