Answer:
30 pupils
Step-by-step explanation:
first you divide 75 and 2.5 to get 30.
20% is equal to .2 if 1 is the whole.
You would multiply the original cost, d, by .2 to get an answer.
Therefore, the expression is: 0.2d
Answer:
x = 11 and H = 39°
Step-by-step explanation:
Complementary angles add up to 90 degrees, so angles G and H will add up to 90 degrees.
Create an equation by adding the expressions together and setting it equal to 90.
(6x - 15) + (3x + 6) = 90
Solve for x by adding like terms first:
9x - 9 = 90
Isolate x and solve:
9x = 99
x = 11
Then, find H by plugging in 11 as x into the expression:
3x + 6
3(11) + 6
33 + 6
= 39
So, x = 11 and H = 39°
Answer:
<h2>f(-8) = - 42</h2>
Step-by-step explanation:
f(x) = 6(1 - x)
To find f(-8) substitute the value of x that's - 8 into f(x) that is for every x in f (x) replace it with - 8
We have
f(-8) = 6( 1 - 8)
= 6(-7)
We have the final answer as
<h3>f(-8) = - 42</h3>
Hope this helps you
The answer is 100, because the word "difference" means subtraction, so we subtract 747 form 847 and we get 100.
