Answer:
If he has 45% of his cheak remaining we already have the remaining so we just to turn it into a fraction
First we put it over 100
<u>45</u>
100
Then we reduce it to the lowest terms
which would be
9/20
Answer:
If Ahmad travel 280 miles the cost of both plans will be the same
Step-by-step explanation:
Let's call x the number of miles traveled by Ahmad.
If we say that C1 is the cost of the first plan and C2 is the cost of the second plan then:
C1 = initial fee + additional cost per mile
C2 = initial fee + additional cost per mile
We want to know for what value of x, cost 1 will be equal to cost 2. Then we equate the equations and solve for x.
1 times 108 because the normal height for a skyscraper is usually way more than any of those
Answer:
Step-by-step explanation:
Given :
re - writing the equation , we have
we need to find the value of a and b for which -2<x < 4 , this means that the roots of the quadratic equation are -2<x < 4.
The formula for finding the quadratic equation when the roots are known is :
- sum of roots(x) + product of root = 0
sum of roots = -2 + 4 = 2
product of roots = -2 x 4 = -8
substituting into the formula , we have:
, which could be written in inequality form as
comparing with , it means that :
