Answer:
180 rolls.
Step-by-step explanation:

x = 81/0.45
x = 180
Answer:
Use F.O.I.L method
First, Outter, Inner, Last
So:
5x*7x= 35x^2
5x*-6= -30x
7x*2= 14x
2*-6= -12
So just add it all up, combine like terms and you have your answer.
35x^2 -16x -12
Answer:
∠DCF = 129°
Step-by-step explanation:
We assume that line CE is between lines CD and CF.
The angle sum theorem applies:
∠DCF = ∠DCE +∠ECF
∠DCF = 75° +54°
∠DCF = 129°
Jim owns 48 cars.
4:3 as x:36
36/3 is 12, so the scale is 12.
x is 4*12 = 48
So 52 words per 1 minute
364 words per x minute
52:1 as is 364:x so
divide 364 by 52 and get 7
she typed 7 minutes
so 40% means 40/100 or 4/10
so 364=4/10
divide 364 by 2
364/2=182=2/10
multiply 182 by 5 ( to make 2/10 into 10/10) and get 910=words total to type
BUT WE WANT TO FIND WORDS LEFT so
910-364=546
she has 546 words left to type
