Answer:

(10x)²

Step-by-step explanation:

For this equation, you can imagine it as 100×x².

If you want to put this all into the brackets, you must square root 100.

The square root of 100 is 10, so the equation can be written as 10²x².

This can be combined to (10x)².

Solve the system using substitution x=3y-11 4x-3y=-26

iragen [17]

Answer:

x=3y-11

then now putting the value of x in second equation

4(3y-11)-3y =26

12y - 44-3y=26

9y=44+26

9y=70

y=70/9

now putting the value of y in 1st equation then

x=3*70/9-11

x=37/3

now checking this is correct or not in 2nd eqn

4*37/3-3*70/9=26

148-70/3=26

26=26

20 pounds to 16 pounds is what present

ExtremeBDS [4]

Answer:

Decreased by 20%.

16 lbs is 80% of 20 lbs.

Step-by-step explanation:

$\frac{y}{100} :\frac{16}{20}$

y × 20 = 16 × 100

20y = 1600

20y ÷ 20 = 1600 ÷ 20

y = 80

100% - 80% = 20%
