Answer:
5x + 10 + 55 = 90
5x = 90 -55 - 10
5x = 90 - 65
5x = 25
5x ÷ 5 = 25 ÷ 5
x = 5
Answer:
x=5
Step-by-step explanation:
If you replace the x in (5x+10)º
(5x+10)º
[5(5)+10]º
[25+10]º
= 35º
Combine the sums for angles M and R
55º+35º
=90º
Therefore, the answer is x=5.

Step-by-step explanation:
Theo bought 2 hot dogs and two drinks for $4.00. At the same concession stand, Vicky bought 3 hot dogs and a drink for $4.50. Write a system of equations and find what is the price of a hot dog concession stand?
Answer:
The hot dog are $2.63
Step-by-step explanation:
Hot Dogs = H
Drinks = D
2H + 2D = 4
Divide both sides by 2
H + D = 2
Subtract D from either side
H = 2 -D
3H + D = 4.50
Plug in 2 - D for H
3(2- D ) + D = 4.50
6 - 3D + D = 4.50
6 - 4D = 4.50
Add 6 to either side
-4D = 10.50
Divide either side by -4
D = -2 . 625
Can anybody help me on number 4? Find the measure of each interior angle of the regular polygon.
Answer:
22.5 degrees
Step-by-step explanation:
there are 8 corners in that polygon and there are 180 degrees inside every polygon
so divide 180 by 8
you should get 22.5 degrees

The graph that is made up of two straight lines, which has an absolute maximum or absolute minimum, and is symmetric belongs to the
function family.
Answer:
This may be a function of the absolte value family.
f(x) = IxI.
f(x) = x if x ≥ 0
f(x) = -x if x ≤ 0
Where this is the parent function, and the graph is shown below in green.
If the coefficient is positive, then the lines open upwards, and we will have a minimum (in this case, when x = 0).
And also in this case, we have symmetry around the value x = 0.
Now, the vertex can also be an absolute maximum if the coefficient is negative, like in the example shown below in color blue (the equation for the blue graph is f(x) = -3*IxI )
The manager of a grocery store determined that the number of bananas remaining on the shelves at her store can be determined by the function b(n) = 150 − 6 n, where n is the number of hours since the store opened. According to this function, how many bananas are left on the shelves after the store has been open for 6 hours?

The equation of the graph line is 2X-3Y=12
What is the x-intercept of the graph?
A. -4
B. -3/2
C.2/3
D.6
Answer:
A. -4
Step-by-step explanation:
For solving for x intercepts analytically. You can set the the y in the equation to 0. So, 2x-3(0)=12, and solving for x will get you -4.
You can also solve graphically by plugging in the equation and looking at where it intercepts the x axis.
List the coefficients from the following expression
3x + 6 - 8x + 1
Answer:
3 and 8
Step-by-step explanation:
Coefficients are just the numbers that accompany the variables. So if you have any number, let's take 4, and put it next to an x: 4x, 4 will be your coefficient.
Find the Value
A.
B.
C.
D.
Answer:
C
Step-by-step explanation:
Using the trig. identity
sin²x + cos²x = 1 ⇒ cosx = ± [tex]\sqrt{1-sin^2x}[/tex]
Here sinθ = [tex]\frac{1}{2}[/tex] , thus
cosθ = ± [tex]\sqrt{1-(\frac{1}{2})^2 }[/tex] = ± [tex]\sqrt{1-\frac{1}{4} }[/tex] = ± [tex]\sqrt{\frac{3}{4} }[/tex] = ± [tex]\frac{\sqrt{3} }{2}[/tex]
Since 0 ≤ θ > 90 then cosθ > 0 , thus
cosθ = [tex]\frac{\sqrt{3} }{2}[/tex] → C
Which is the solution to the following system x+2y+z=9
X-y+3z=13
2z=10
Step-by-step explanation:
I'm not sure but,here you go
2z = 10
z = 10 ÷ 2 = 5
x + 2y + z = 9
x + y + 3z = 13
____________
x + 2y + 5 = 9
x + y + 3(5) = 13
_____________
x + 2y = 9 - 5
x + y = 13 - 15
___________
x + 2y = 4
x + y = -2 (×-1)
___________
x + 2y = 4
-x - y = 2
___________
y = 6
x = -2y - z + 9 = -2(6) - 5 + 9 = -12 - 5 + 9 = -8
If you wanna check,
x + y +3z = 13
(-8) + 6 + 3(5) = 13
x = -8 , y = 6 , z = 5
I'm not very sure but here you go,I might be wrong^^
Solve the two steps equations below and check your solution R/2-8=16
Answer:
r= 48
Step-by-step explanation
r/2 - 8 = 16
+8 +8
r/2 = 24
multiply both sides by two so it cancels out and you get r by itself.
the 2 cancels out and 24 times 2 = 48
r= 48
