XZ : YZ = 5:8
3 * XY = 27 (9*3 = 27)
3*XZ : 3*YZ = 3*5 : 3*8
SW : TW = 15 : 24
SW = 15 and TW = 24
Answer:
x=0
x=7
Step-by-step explanation:
x²-x-1=6x-1
x²-x-1-6x+1=0
x²-7x=0
x(x-7)=0
x=0
x-7=0
x=7
D. About 122 units I just took the test
She will be $1.40 under budget.
8% = 8/100 = 0.08
Adding this to 100% of the price of the shoes, we get 108% = 108/100 = 1.08.
We multiply the price of the shoes by this:
45*1.08 = 48.60
Subtract this from 50:
50 - 48.60 = 1.40
