Ryo accidentally ordered 240% as many eggs as his restaurant needed. What fraction of the number of eggs his restaurant needs di
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

A. Factor 28 + 7g  7(g <span>+ 4) 

add 
28 </span><span>+ 7g 

= 7 (g </span>+ 4)

B. (12r + 15) – 65 Remove parentheses
12r+15-65

= 12r - 50 

C. 24 – (8p – 12)

24 - (8p - 12) = -8p + 36 

24 - (8p - 12)  -(8p - 12) 8p + 12

= 24-8p+12

Simplify 24-8p+12 

Group like terms
-8p+12+24

Add the numbers  12+24=36

Answer is -8p+36

netineya [11]
Expand the square: 4(x-11)^ =25
4(x-11)(x-11)=25

Distribute : 4(x-11)(x-11)=25
4(x(x-11)-11(x-11))=25

Distribute: 4(x(x-11)-11(x-11))=25
4(x^-11x-11(x-11))=25

Solution: x=17/2
x=27/2
