Convert 3/4 into decimal form = 0.75
0.75 x 7 = 5.25
Convert 5.25 into a fraction = 5 1/4
In conclusion, 7 trails were conducted.
Hope this helps!:D
Answer:
-22
Step-by-step explanation:
18 + 4 = 22
then just add the negative to 22
-22
12 x 40 = hours she worked = 480
3 x 31 = appointment fee = 93
480 + 93 = 573
Since vertical angles are congruent, (4x+7)=5(x-4). So simplifying we get 4x+7=5x-20. If we add 20 on both sides we get 4x+27=5x. Now when we subtract x from both sides, we get x=27
Remmber you can't divide by 0
if you can canel out something from both that is a hole
exampe if you had y=[(x-2)(x+3)]/(x-2), then the equation is y=x+3 with a hole at x=2 (since x=2 to make x-2=0 true)
so

y=2x-3 is theh graph
zero at y=0 or x=3/2
(1.5,0) is the zero
set factored out thing to zero
x+4=0
x=-4
at x=-4
input into later one
y=2x-3
y=2(-4)-3
y=-8-3
y=-11
hole at (-4,-11)
the hole is at (-4,-11)
zero at (3/2,0)
