120+24 divided by 8=
144 divided by 8= 18 because 18 times 8 equals 144
Assuming the numbers are exponents expect the coefficient of 2, top expression, -12x^3y^6, multiply bottom
and= 72x^4y^8
Answer:
1 quart = .947 L
3 Q = 2.841 L
So you should use 2.841 L to dissolve the powder
Just set up 2 equations.
267 = 10(11) + 5(x) + 1(y)
x = y - 7
you can plug the second into the first and get
267 = 110 + 5(y - 7) + y
157 = 5y - 35 + y
6y = 192
y = 32
x = 32 - 7 = 25
thus, 32 $1's and 25 $5's
