If you are solving for x, you could set it up like this:
x + 8 = 2x + 5
-5 - 5
x + 3 = 2x
-x -x
3 = x
So now that you have the value of x. You can plug it in. The first one is x + 8 or 3 + 8 since the value of x is 3. Then the next one is 2x + 5 or 2(3) + 5.
Answer:
D
Step-by-step explanation:
if a<b,then b<a is the answer
A) the perimeter of a triangle is the bottom plus the left slanty side plus the right slanty side, but you need the bottom in ft so that would be 6 ft. the perimeter is 13 ft
b) 1 yard
Answer:
x = s/2
Step-by-step explanation:
● s states have joined the union in 1788
● half of s have joined in 1889
Let x be the number of states that have joined in 1889
● x = (1/2)× s
● x = s/2
Answer:
y=5/3 or y=1.67
Step-by-step explanation:
In this problem we have that
(5x+8)=21x ----> given problem
21x-5x=8
16x=8
x=0.5
In the same way
Remember that the slope of a line is a constant
so
20y-2=17y+3
Solve for y
20y-17y=3+2
3y=5
y=5/3 or y=1.67
