Answer:
q=
−4t+7u over 8r
Step-by-step explanation:
8qr+4t=7u
Step 1: Add -4t to both sides.
8qr+4t+−4t=7u+−4t
8qr=−4t+7u
Step 2: Divide both sides by 8r.
8qr
8r
=
−4t+7u
8r
q=
−4t+7u
8r
Answer:
q=
−4t+7u
8r
8-3(x+6)
explanation:
it just makes sense lol but also bc “8 decreased by three” means “8 minus 3”
then “times” means “multiply”
then “a sum” means “addition”
then “a number” since we don’t know what a number is then we use “x”
“and” means “addition”
“a number and six” means “x+6”
Answer:
- 9
Step-by-step explanation:
2/3 x - 4 = -2
2/3 x = -2+4
x = 6 * (-3/2)
9 = -9

Answer:
2y^3-7y^2+7y
Step-by-step explanation:
7y - 2y^3 + 5y^2 - ( 12y^2 – 4y^3)
Distribute the minus sign
7y - 2y^3 + 5y^2 - 12y^2 + 4y^3
Combine like terms
2y^3-7y^2+7y
