Answer:
11Step-by-step explanation:
The sum of interior angles is equal to exterior angle
Given the following
Interior angles = 5x + 10 and 58
Exterior angle 11x+2
According to the postulate:
5x + 10 + 58 = 11x + 2
5x + 68 = 11x + 2
Collect like terms
5x -11x = 2 - 68
-6x = -66
x = -66/-6
x = 11
The value of x is 11
Can someone explain how to work this out please ?
Answer:
x=4
Step-by-step explanation:
f(x) = (x-2)^5 +3
Let f(x) = 35
35 = (x-2)^5 +3
Subtract 3 from each side
35-3 = (x-2)^5 +3-3
32 = (x-2)^5
Take the fifth root of each side
32 ^ (1/5) = (x-2)^5^ 1/5
2 = x-2
Add 2 to each side
2 +2 = x-2+2
4 =x

solve the system by substitution y=x-8 y=2x-14
Answer:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form:
(6,-2)
Equation Form:
x=6,y=-2
Step-by-step explanation:
The value of x is 6 and y is -2.
What is Substitution Method?The algebraic approach to solving simultaneous linear equations is known as substitution method. The value of one variable from one equation is substituted in the second equation in this procedure, as the name implies.
When a variable (or set of letters) in an algebraic statement is substituted, its numerical value is used instead.
Given:
y=x-8..................(1)
y=2x-14.................(2)
Substitute the value of y from equation (1) to equation (2), we get
x-8 = 2x- 14
2x - x = -8 + 14
x = 6
and, y= x-8
y= 6-8
y= -2.
Hence, the value of x is 6 and y is -2.

Solve for x:
7x = 105
Answer:
X=15
Explanation: You have no like terms to combine and are at the last step of the algebraic equation. So, you would divide 7 on both sides. 7 by 7 cancels it out and 105 divided by 7 equals 15. Hope this helps ^-^.
The solution to the equation 7x = 105 is x = 15.
We have the equation: 7x= 105
To solve for x in the equation 7x = 105, we need to isolate x on one side of the equation.
Divide both sides of the equation by 7:
(7x)/7 = 105/7
Simplifying:
x = 15
Therefore, the solution to the equation 7x = 105 is x = 15.

Please help me :)
Answer:
??You texted incomplete question.
By the way, x = 90
The Nguyen family is traveling cross-country, driving 300 miles each day. Let 2 represent the number of days in the trip and let y represent the total number
of miles driven.
Write an equation to model their trip.
Enter the correct equation in the box.
Step-by-step explanation:
y = Total number of miles driven
= Number of days * Number of miles per day
= (x) * (300).
Therefore the equation is y = 300x.
When x = 2, y = 300(2) = 600.
The Nguyen family drove 600 miles during the 2 days.

Step-by-step explanation:
I really hope this helps, if not I am so sorry
Answer:
G= 1/6p -15
Step-by-step explanation:
Let's solve for g.
p=6g+90
Step 1: Flip the equation.
6g+90=p
Step 2: Add -90 to both sides.
6g+90+−90=p+−90
6g=p-90
Step 3: Divide both sides by 6.
6g/6 = p−90/6g
=1/6p−15
How many cubic centimers of water can this paper cone cup hold?
Answer:
B: 48π cubic centimeters
Step-by-step explanation:
A: 216π cubic centimeters
B: 48π cubic centimeters
C: 144π cubic centimeters
D: 192π cubic centimeters
Volume of the paper cone cup = 1/3πr²h
Diameter = 8 cm
Radius, r = diameter / 2
= 8 cm / 2
= 4 cm
Height, h = 9 cm
Volume of the paper cone cup = 1/3πr²h
= 1/3 × π × 4² × 9
= 1/3 × π × 16 × 9
= (1 × π × 16 × 9) / 3
= 144π / 3
= 48π cm³
Volume of the paper cone cup = 48π cm³

Find the measure of each missing angle.
Answer:
m< 3 = 180 - 93
m< 3 = 87 degrees
m< 4 = 180 - 87 - 49
m< 4 = 44 degrees
m< 2 is vertically opposite to the 49 degree angle given
m< 2 = 49 degrees
m< 1 = 180- 68 - 49
m< 1 = 63 degrees
The measure of each missing angle are; m< 1 = 63, m< 2 = 49, m< 3 = 87 and m< 4 = 44 degrees
What are vertically opposite angles?The vertically opposite angles are those angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.
We can determine angle 3 as;
m< 3 = 180 - 93
m< 3 = 87 degrees
Also,
m< 4 = 180 - 87 - 49
m< 4 = 44 degrees
We can see that m< 2 is equal to 49-degree angle by a vertically opposite angle.
m< 2 = 49 degrees
m< 1 = 180- 68 - 49
m< 1 = 63 degrees
Hence, the measure of each missing angle are; m< 1 = 63, m< 2 = 49, m< 3 = 87 and m< 4 = 44 degrees

what is 9 : 45 = 6 : ?
Answer:6:45
Step-by-step explanation:
Answer:
x = 30
Step-by-step explanation:
a ratio is just a fraction
9:45 = 9/45
6:x = 6/x
now you have 9/45 = 6/x
cross multiply:
9 * x = 45 * 6
9x = 270
divide both sides by 9
9x/9 = 270/9
x = 30
Can I get some help with this is the Last question
Answer:
x = 11
Step-by-step explanation:
Here, we want to get the value of x
Let’s start by looking at the point U
Now, we can see angles on a straight line at that point
Mathematically, angles on a straight line are supplementary
What this mean is that they add up to 180
Now, the value of the angle that falls into the triangle on that straight line will be;
180-(11x + 12)
Now, we have all the angles of the triangle
Mathematically, the sum of all is 180 as the a sum of the angles of a triangle is 180
5x + 10 + 58 + 180-(11x+2 )= 180
5x + 10 + 58 -11x-2 = 0
-6x+ 66 = 0
6x = 66
x = 66/6
x = 11
