1: Identify the angle.

The following angle is a 90.

2: Set up the equation.

x + (3x + 10) = 90

3: Combine like terms.

4x + 10 = 90

4: Solve for x.

4x + 10 = 90

-10 = - 10

--------------------------

4x = 80

------------------

4 4

x = 20

Your answer is x = 20.

Hope this helps! Have a good day/night! c:

Add all the similar terms
4x+10 = 90
4x = 90 -10
4x = 80
80/4= 20
x = 20

Then substitute x = 20 in to make sure it’s right (:
it is thought so don’t worry (:

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks. Today's cafeteria s

kobusy [5.1K]

Answer:

Equation 1: 14t + 61s = 150

Equation 2: 14t + 25s = 78

Use Elimination (x)

(-1) (14t + 25s) = (78) (-1)

-14t - 25s = -78

14t + 61s = 150

+ -14t - 25s = -78

--------------------------

36s = 72

s = 2

Salad costs $2

Then find t

14t + 61(2) = 150

14t + 122 = 150

14t = 28

t = 2

Sandwich costs $2

What is the solution to this system of equations?

amm1812

Answer:

Step-by-step explanation:

(i) x+2y=4

(ii) x=4-2y

(iii) 2x-2y=5

substituting (ii) in (iii)

2x-2y=5

2(4-2y)-2y=5

8-4y-2y=5

-6y=5-8

-6y=-3

(iv) y= $\frac{1}{2}$

substituting (iv) in (ii)

x=4-2y

x=4-2× $\frac{1}{2}$

x=4-1

x=3

∴ B.(3, $\frac{1}{2}$ )

HOPE IT HELPS YOU!!!!
