Step-by-step explanation:
40/24=10/6
40/10=4
24/6=4
(40/24)/(4/4)=10/6
(10/6)(4/4)=10/24

Step-by-step explanation:
Forming an algebraic equation and solving:
Let the number she thought = 'x'
5/6 of the number :
Multiply both sides by 6
5x = 35 * 6
Divide both sides by 5,
Answer:
F
Step-by-step explanation:
4.85-4.15=0.7 divided by 2 = 0.35+4.15=4.5*25 cause 30-20=10 divided by 2=5+20=25*4.5=112. closest to that is 120
Answer:
after 2 months the total cost will be the same.
Step-by-step explanation:
21+20x=27+17x subtract 17x on both sides because its the lowest coefficient
20x- 17x = 3x 17x-17x= cancel out
subtract 21 on both sides because its the lowest number
21-21= cancel out. 27-21=6
divide the coefficient by both sides
3x/3= x
6/3= 2
x=2
Answer:
3) f(x) = 3(x + 2)^2 - 1.
Step-by-step explanation:
f(x) = 3x² + 12x +11
f(x) = 3(x^2 + 4x) + 11 Completing the square:
f(x) = 3[(x + 2)^2 - 4] + 11
f(x) = 3(x + 2)^2 -+3*-4 + 11
f(x) = 3(x + 2)^2 - 12 + 11
f(x) = 3(x + 2)^2 - 1.
