Hey there!

Formula: πr^2

r = radius

pi = 3.1415926535898 (but we can say it approximately equals 3.14)

Your equation (3.14)(4.2)^2 = answer

4.2^2 = 4.2 × 4.2 = 17.64

New equation: 17.64 × 3.14 = 55.3896

We round our answer to the nearest tenth

Answer: 55.4 ☑️

Good luck on your assignment and enjoy your day!

Examine this system of equations. Which numbers can be multiplied by each equation so that when the two equations are added toge

podryga [215]

Answer:

18 times the first equation and 8 times the second equation

Step-by-step explanation:

we have

$\frac{1}{4}x-\frac{1}{6}y=5$ ------> first equation

$\frac{4}{5}x+\frac{3}{8}y=10$ ------> second equation

step 1

Multiply the second equation by 8 both sides to remove the fraction in the variable y

$8(\frac{4}{5}x+\frac{3}{8}y)=10(8)$

$\frac{32}{5}x+3y=80$

step 2

Multiply the first equation by 18 both sides to obtain the coefficient -3 in the variable y

$18(\frac{1}{4}x-\frac{1}{6}y)=5(18)$

$\frac{18}{4}x-3y=90$

step 3

Adds the new equation 1 and equation 2

$\frac{18}{4}x-3y=90\\\\ \frac{32}{5}x+3y=80\\ -------$

The y-term is eliminated

therefore

The answer is

18 times the first equation and 8 times the second equation
