12/25 are girls 1 - 12/25 =13/25 13/25 boys, 25 * 4 = 100 so 13 * 4=17 so 0.17 boys i think. Sorry if I'am wrong
7.1 is the value of Ef where cd=df
Answer:
-88 mph
Step-by-step explanation:
We can use the relation ...
time = distance/speed
to compare the times in the two directions.
The wind speed is -88 miles per hour.
_____
The problem statement tells us the travel is slower <em>with</em> the wind than <em>against</em> the wind. Hence "with the wind" must be subtracting from the net speed. That is, the wind speed is negative.

Answer: 7(x+3)(x-2)</h3>
========================================
Explanation:
First factor out the GCF 7
7x^2 + 7x - 42
7*x^2 + 7*x + 7*(-6)
7(x^2 + x - 6)
Now focus on factoring x^2+x-6
We need to find two numbers that multiply to -6 and add to 1. Those values are 3 and -2. That means x^2+x-6 factors to (x+3)(x-2).
The 7(x^2 + x - 6) then turns into 7(x+3)(x-2)
The factor out front, the "7", is the integer factor. The other factors (x+3) and (x-2) are binomial factors.
Step-by-step explanation:
let x represent the monthly budget.
13 % of x = $ 2600
(13/100) * x = $2600
13/100 = $2600/x
thus, the answer is D.
hope this helps you!
