BARSIC [14]3 years ago

So we'll assume the number is x.

So,

15+\frac{x}{2}= 9.

Now, we solve for x:

\frac{x}{2}= 9-15

\frac{x}{2}= -6

x = -6*2

x = -12


Check work:

15+\frac{-12}{2}= 9

15+(-6) = 9

15-6 = 9

9 = 9

Write an equation that you can use to find the value of x.
MariettaO [177]
Line CA is a straight line, meaning it adds up to 180°

Line BE splits the line into two supplementary angles, because when the two angles are added together they will equal 180°

Using the rule of supplementary angles, we can then make the equation 3x + 8x + 15 = 180

Now, simplify the equation by combining like terms

11x + 15 = 180

To solve, isolate x

11x + 15 = 180
11x = 165
x = 15

navik [9.2K]

10t = b - 4

12b+8t = $348

This is a system of equations. I’ll be solving through substitution.

In the first equation. solving for b (the easier variable to isolate) gives you:

b = 10t + 4

Substitute this into the second equation:

12(10t+4) +8t = 348

120t+48+8t = 348

128t = 300

t = 2.34375 —> round it to the nearest cent to get 2.34 dollars

b = 10t+4

b = 10(2.34)+4

b = 27.4 dollars
