What is the solution to this system of equations? y = x - 20 x + y = 84

Pepsi [2]

Answer:

(52, 32 )

Step-by-step explanation:

Given the 2 equations

y = x - 20 → (1)

x + y = 84 → (2)

Substitute y = x - 20 into (2)

x + x - 20 = 84, that is

2x - 20 = 84 ( add 20 to both sides )

2x = 104 ( divide both sides by 2 )

x = 52

Substitute x = 52 into (1) for corresponding value of y

y = 52 - 20 = 32

Solution is (52, 32 )

Two complementary angles are in the ratio 7:8. What is the measure of the larger angle?

yan [13]

Answer

Step-by-step explanation:

We know that sum of complementary angle adds to 90°

Let the angles be 7x and 8x

First of all, finding the value of x

$\sf{7x + 8x = 90 °}$

Collect like terms

⇒ $\sf{15x = 90 °}$

Divide both sides of the equation by 15

⇒ $\sf{ \frac{15x}{15} = \frac{90}{15} }$

Calculate

⇒ $\sf{x = 6 °}$

The value of X is 6°

Now, substituting / Replacing the value of x

⇒ $\sf{7x = 7 \times 6 = 42}$

⇒ $\sf{8x = 8 \times 6 = 48}$

The measure of larger angle is 48°

Hope I helped!

Best regards!!
