She had $10 dollars and the 15 is far so you need to have only one estimate.
Answer:
40
Step-by-step explanation:
Ratio of cars to total:
32:80
so we can make another ratio with x
x:100
now make them fractions and cross-multiply
32/80 = x/100
32(100) = 80x
80x = 3200
x = 40
Answer:
-11≤x
Step-by-step explanation:
Given
6.7 ≥ -0.2x +4.5----------------collect like terms
6.7-4.5 ≥ -0.2x--------------divide by -0.2 both sides
2.2/-0.2 ≥ -0.2/-0.2x-------------------reverse the sign
-11 ≤ x
Answer:
1)all numbers less than -5 and greater than 5
Step-by-step explanation:
We are given
x<-5
and
x>5
So
Looking at both the inequalities one by one, The solution will consist of all the numbers that are less than -5 and greater than 5. The numbers between -5 and 5 will be excluded from the solution..
Hence,
1)all numbers less than -5 and greater than 5
is correct ..
