The answer would be 19. If u have a calculator you can just plug it in though
Answer:
100 girls and 20 boys
Step-by-step explanation:
since its 5 times as many girls multiply 20 by 5 which is 100 and then boom 20 boys cause 100 divided by 5 is 20
Answer:
$14
Step-by-step explanation:
The total amount, C charged by an electrician for h hours of work is ;
C= 7h+125
If the electrician spends 2 more hours on Sanchez job than Ronald, then the amount Mrs Sanchez paid more than Ronald can be obtained thus:
From the equation :
C= 7h+125
The slope relation with number of hours worked gives the change in amount paid for differebt work hours. Since the intercept is constant, we ignore its value in this exercise.
For 2 more hours of work :
Additional amount = 7h ; h = 2
7h = 7 * 2 = 14
Hence, Mrs Sanchez pays $14 more.
Answer:
see below
Step-by-step explanation:
x+2<4
Subtract 2 from each side
x+2-2 < 4-2
x<2
There is an open circle at 2 and since x is less than, the lines goes to the left
Given: ∠3 = ∠4
1) ∠1 = ∠4 because of vertical angles
2) ∠4 = ∠3, given
3) So ∠1 = ∠4 = ∠3, so ∠1 = ∠3, because of transitive property
2) ∠3 + ∠2 = 180 degrees because definition of a straight line
3) ∠1 + ∠2 = 180 degrees, using substitution
4) Since ∠1 + ∠2 adds up to 180 degrees, that makes them supplementary angles.
