I tryed my best to figure out what all of the numbers were. if i got any wrong then please tell me and i will put the right answer in the comments.
1) 3/5= 5/x (cross multiply)
3x=5(5)
3x=25
x= 25/3 -or- 8.33
2) 2/4=x/12<span> (cross multiply</span><span>)
</span> 2(12)=4x
24=4x
6=x
3) 10/x=5/9<span> (cross multiply</span><span>)
10(9)=5x
90=5x
18=x
4) 5/5=x/18</span><span> (cross multiply</span><span>)
5(18)=18x
90=18x
5=x</span>
Answer: option d.
Step-by-step explanation:
We have the function:
y = f(x) = x^2 - 1
The output is 99 when y = 99, and the input is x.
Then we need to solve:
y = 99 = x^2 - 1
for x.
99 = x^2 - 1
99 + 1 =x^2
100 = x^2
√100 = x
10 = x
The correct option is d, input equals 10.
X + 2(x - 4) = 62
x + 2x - 8 = 62
3x - 8 = 62
3x = 70
x = 23 1/3 cm
Answer:
$158.75
Step-by-step explanation:
Given:
The Maple Car Rental Comany charges a flat fee of $45 plus 35 cents per mile
And we have to write a linear equation that gives the total cost in terms of numbers of miles driven then find the total cost if the renter drives 325 miles.
Solution:
Total cost = 35 cents of renter drives in miles + fixed charge of the car
Total cost = 

Thus, total cost is $158.75, when the renter drives 325 miles.
