21x + 84 + 12x - 16
33x + 68
The correct answer is 1.) 33x + 68.
Hope this helps!
We are asked in the problem to deterimne the point slope form that is y - y1 = m(x-x1),. Substituting, m = 3 and x1 = 2
Translating,
y + a = 3*(x-2).
Ahnswer to this problem then is C.
Answer:
t = (v-u)/y
Step-by-step explanation:
yt = v - u
t = (v-u)/y
Answer:
20
Step-by-step explanation:
We write what we know.
Jimmy
$50/mo app 65¢ or .65
Lisa
$55/mo app 40¢ or .40
a = number of apps
The difference will come from the number of apps, a.
We need them to equal each other so let's write an equation.
$50 + .65a = $55 + .40a
We need to solve for a.
$50 + .65a = $55 + .40a subtract $50 for each side.
$50 - $50 + .65a = $55 - $50 + .40a
.65a = $55 - $50 + .40a
.65a = $5 + .40a subtract .40a from each side
.65a - .40a = $5 + .40a - .40a
.65a - .40a = $5
.25a = $5 Divide each side by .25
.25a/.25 = $5/.25
a = $5/.25
a = 20
So Jimmy and Lisa need to download 20 apps for their bill to be the same.
