try to change all variable to the number below

2(4)+3(16)^2/4(8)^2-2(4)

8+48^2/32^2-8

so now you can do multiplication and division first

48^2=96

96/32=3

Anarel [89]

Answer:

Ryo ordered $\frac{12}{5}$ of the amount of eggs his restaurant needed

Step-by-step explanation:

Let's call z the number of eggs the restaurant needs

Ryo ordered 240% of the eggs he needed. Then Ryo ordered:

$\frac{240}{100}$ z.

This fraction can be simplified by dividing by 10 in the numerator and denominator.

Then it is:

$\frac{24}{10}$

It can be further simplified by dividing by 2 in the numerator and denominator:

$\frac{12}{5}$ z

Ryo ordered $\frac{12}{5}$ of the amount of eggs his restaurant needed

There are two numbers, one is 7 more than twice the other. The sum of the numbers is 43. Make the equation to find the smaller n

Mrrafil [7]

Answer:

Smaller number: 12

Greater number: 31

Step-by-step explanation:

Hi there!

Let x equal to the smaller number.

Let y be equal to the greater number.

1) Translate the information into equations

"One is 7 more than twice the other"

⇒ $y=2x+7$

"The sum of the numbers is 43"

⇒ $x+y=43$

2) Use substitution to solve for the smaller number

$x+y=43$

Plug the equation $y=2x+7$ into the above equation

$x+(2x+7)=43\\x+2x+7=43\\3x+7=43$

Subtract both sides by 7

$3x+7-7=43-7\\3x=36$

Divide both sides by 3 to isolate x

$\frac{3x}{3} = \frac{36}{3} \\x=12$

Therefore, the smaller number equates to 12.

3) Use substitution to solve for the greater number

$x+y=43$

Plug in x as 12

$12+y=43$

Subtract both sides by 12 to isolate y

$12+y-12=43-12\\y=31$

Therefore, the greater number equates to 31.

I hope this helps!
