The ages of three sisters are consecutive integers. If the sum of three sisters ages is 54 how old are the sisters?

1 answer:

3 0

Let's say S is the age of the youngest sister. Then the age of the middle sister is S + 1, and the age of the oldest sister compared to the youngest is S + 2 we have54 = S + (S+1) + (S+2)which is the same as54 = 3S + 3 divide both sides by 354 / 3 = S + 118 = S + 1 subtract one from both sides17 = S check54 = 17 + 18 + 19 Hope this helps!!!

Nataliya [291]

The U.S RDA for protein is 46g for girl

If a piece of fried chicken contains 23g

To find the pieces of chicken she is to eat to satisfy the U.S RDA requirement,

The number of pieces of chicken is

$\text{Number of pieces}=\frac{U.S.\text{ RDA g protein required for a girl}}{g\text{ of protein in a piece of chicken}}$

The number of pieces of chicken is

$\begin{gathered} \text{Number of pieces of chicken}=\frac{46}{23}=2\text{ pieces of chicken} \\ \text{Number of pieces of chicken}=2\text{ pieces of chicken} \end{gathered}$

Hence, the right option is B

#7. What are the values/ how do I do it

Tasya [4]

Answer:

x =2

SK = 21

KY = 13

SY = 34

Step-by-step explanation:

we can see from the picture the following:

SK + KY = SY equation 1

SK=13x-5 equation 2

KY = 2x+9 equation 3

SY = 36-x equation 4

using equation 2, equation 3 and equation 4 in equation 1 we have:

13x - 5 + 2x + 9 = 36-x

15x +4 = 36 - x

15x +x = 36-4

16x = 32

x = 32/16

x= 2

using x as 2 we evaluate it in equation 2, equation 3 and equation 4:

SK=13(2)-5 = 21

KY= 2(2) +9 = 13

SY = 36-2 = 34
