Step-by-step explanation:
48:44= 12:11
Answer:
2√3
Step-by-step explanation:
5y2+20=80
Step 1: Subtract 20 from both sides.
5y^2+20−20=80−20
5y^2=60
Step 2: Divide both sides by 5.
5y^2
/5 =
60/5
y2=12
Step 3: Take square root.
y=√12
y=2√3
Answer:
x=5
y=30
x=15
Step-by-step explanation:
y=3x=15, then x=15/3, x=5
x=10, then y=3x=3*10=30
y=3x=45, then x=45/3, x=15
