A cell phone company charges $45 per month for unlimited calls and $0.25 per text messages. Another call phone company $0.15 per text messegaes and $70 per month for unlimited calls. Write an equation to reoresent when the cost from both compsnies will be the same after one month
Answer:
You first start by making your equation: 45 +.25x = 70 +.15x. then subtract .15x from both sides. it should look like 45 +.10x = 70. subtract 45 from both sides then you get .10x = 25. divide 10 to both sides and you get 250. so the two companies will be the same at 250 texts.

Help plz. 4x^2-10x=84
Answer:
my brain just died sorry
Step-by-step explanation:
Answer:
x = 6
4x2−10x=84
Step 1: Subtract 84 from both sides.
4x2−10x−84=84−84
4x2−10x−84=0
Step 2: Factor left side of equation.
2(2x+7)(x−6)=0
Step 3: Set factors equal to 0.
2x+7=0 or x−6=0
x=

What is the vertex of this parabola? y= 2x² + 4x +5
Answer:
vertex = (- 1, 3 )
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 2x² + 4x + 5 ← is in standard form
with a = 2, b = 4, then
[tex]x_{vertex}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1
Substitute x = - 1 into the equation for corresponding value of y, that is
y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3
vertex = (- 1, 3 )

If triangle ABC has the following angle measurements, what is the set-up to solve for x?
∠A= 4x - 17
∠B= 3x + 8
∠C= x + 13
4x - 17 + 3x + 8 + x + 13 = 180
4x - 17 = 3x + 8 + x + 13
4x - 17 - 3x + 8 - x + 13 = 180
4x - 17 - 3x + 8 - x + 13 = 180
Answer:
A
Step-by-step explanation:
The answer is the first one. We've used that in previous questions.
B is wrong. It needs to be equal to something (180 in this case). B is also saying that the first angle is = to the sum of the other two. Not so.
C is wrong. the third angle's x term has to be plus.
D has the same problem.

there were 252 people at the concert . If 90% of the seats were filled, how many seats are in the auditorium?
Answer:
280 seats total
Step-by-step explanation:
90/100 = 252/x
To find x, cross multiply.
90x = 25,200
Divide both sides by 90 to get the variable alone.
x = 280 seats
Klein opened a savings account that paid 5% simple interest with 6,000 in principal. If Klem left that money untouched in the account for ten years,then how much interest with he have earned?
Answer:
I= $3,000
Step-by-step explanation:
Giving the following information:
Klein opened a savings account that paid 5% simple interest with 6,000 in principal.
Number of periods= 10 years
To calculate the interest earned, we need to use the following formula:
I= P*r*t
P= principal
r= interest rate
t= time
I= 6,000*0.05*10
I= $3,000
33 is 90% of what number? Round to the tenths place.
Answer:
36.7
Step-by-step explanation:
Since 33 is 90% of a number, you can divide 33 by 9 to get 3 2/3. This 3 2/3 is 10% of the number, so multiply 3 2/3 by 10 to get 36 2/3. 36 2/3 rounded to the nearest tenth is 36.7, so there's your answer. Hope it helps!
