Answer:
120 bricks = 10 kg
120 bricks × 10 kg = 1200 kg
1200 kg + 9000 kg = 10200 kg
Answer:
1 one-dollar bill
3 quarters
3 pennies
Step-by-step explanation:
5.00 - 3.22 = 1.78
1 one-dollar bill
3 quarters (25 x 3 = 75 cents)
3 pennies (3 x 1 = 3 cents)
SOLUTION:
Let whole number = x
x + 2x^2 = 21
2x^2 + x - 21 = 0
2x^2 + 7x - 6x - 21 = 0
x ( 2x + 7 ) - 3 ( 2x + 7 ) = 0
( 2x + 7 ) ( x - 3 ) = 0
2x + 7 = 0
2x = - 7
x = - 7 / 2
OR
x - 3 = 0
x = 3
ANSWER:
Therefore, as 3 is a whole number while - 7 / 2 isn't a whole number, the whole number must be 3.
Hope this helps! :)

(if i get this wrong im so sorry :(
Use the Pythagorean theorem. The equation for this right triangle would be a^2+b^2=c^2. Since you have one leg and the hypotenuse, you can plug these into the equation. It would be 7^2+b^2=12^2. Do the exponents. You will get 49+b^2=144. You need to get b by itself so subtract each side by 49. You get the equation b^2=95. Square root each side to get b=9.746. This rounds to 9.7. So the answer is A. Hope this helps! ;)
