4 0

Answer:

For x, the equation is x=3(y+5)

Step-by-step explanation:

Given:  the equation x over 3-5=y

We have to solve for x,

Consider the given equation the equation x over 3-5=y

Here, over means divide, so,

Mathematically written as ,

\frac{x}{3}-5=y

Solving foor x,

adding 5 both sides, we have,

\frac{x}{3}-5+5=y+5

On solving, we have,

\frac{x}{3}=y+5

Now, multiply both side by 3, we have,

3(\frac{x}{3})=3(y+5)

On simplification, we have,

x=3(y+5)

Thus, for x, the equation is x=3(y+5)

Quinzel and Joseph sell shoes. Last month Quinzel sold 18 less pairs
hichkok12 [17]

Answer:

Quinzel sold 17 pairs of shoes last month.

Step-by-step explanation:

Let be "Q" the number of pairs of shoes Quinzel sold last month and "J" the number of pairs of shoes Joseph sold last month.

Set up a system of equations:

\left \{ {{Q=J-18} \atop {Q+J=52} \right.

Solve for "J" from the first equation:

J=Q+18

Applying the Substitution Method, you get:

Q+J=52\\\\Q+(Q+18)=52\\\\2Q=52-18\\\\Q=\frac{34}{2} \\\\Q=17

Emilia took a math quiz last week. She got 19 problems correct and 76 problems incorrect. What percentage did Emilia get correct
Volgvan

Answer: 20%

Step-by-step explanation:

To find the total number of problems Emilia solved, we can first add 19 and 76 to get:

19 + 76 = 95

Next, to find how many problems Emilia got correct out of the total, we can use the number of problems correct (19) and divide it by the total number of problems (95) to get:

19 ÷ 95 = 0.2

Finally, to make 0.2 a percentage, we can multiply it by 100 to get:

0.2 X 100 = 20

Therefore, Emilia got 20% of the problems correct.
