To solve the system of equations below, Pedro isolated the variable y in the first equation and then substituted it into the sec
Reil [10]

Answer:

Resulting equation will be 5x²=36.

Step-by-step explanation:

The given equations are 5y = 10x-----(1)

and x²+y²=36------(2)

Now we substitute the value of y from equation (1) into equation (2).

5y = 10x ⇒ y = 2x

Then equation (2) will be x²+(2x)²=36

x²+4x²=36 ⇒ 5x² = 36

So the equation after substitution of the value of y from equation 1 will be 5x² = 36.

Oksi-84 [34.3K]

Answer: The percentage change is 56.67%.

Step-by-step explanation:

= 68 meals

The percentage change = \dfrac{\text{change in meals}}{\text{Original quantity of meals}}\times100

=\dfrac{68}{120}\times100\\\\=56.67\%

Hence, the percentage change is 56.67%.
