Answer:
v=1
Step-by-step explanation:
-8 + 5v = -3
add 8 to both sides of the equasion
5v = 5
divide both sides by 5
v = 1
proof:
-8 + 5*1 = -8+5 = -3
Answer:
11
Step-by-step explanation:
Focus on the product of a number and three part first
3×X=?
next it says 18 is 15 less than the product so the product is equal to
18+15=33
now Rewrite the initial equation with the product
3×X=33
now divide by three on both sides to isolate the X , that will result in
X=11
good luck!!! I believe in you!!!
12:36 for the first one
6:21 for the second one
And 21:15 because let's say that for every 7 cans that a group gets , the other group gets 5
Answer:
x=7
Step-by-step explanation:
This problem uses vertical angles! I'm sure you know this but just in case I will explain. Whenever there are two angles that are across from each other in a junction of two straight lines, they are perfectly equal! In this problem, the angles 6x-7 and 4x+7 are the same angle, so those equations have to have the same answer. In order to solve it, you need to write the equations like this:
6x-7=4x+7
From there you can solve for x. I will write my process here:
2x-7=7
2x=14
x=7
Just writing those vertical angle equations as equalities of each other should give you the answers you are looking for!
