Step-by-step explanation:
4(3x-1)=9-x
12x-4=9-x
12x+x=9+4
13x=13
x=13/13
x=1
Solve for x. 20x + 5 = 5x + 65
Answer:
x=4
Step-by-step explanation:
move the variable to the left side and change its sign
20x-5x=65-5
collect like terms
15x=65-5
15x=60 divide both side by 15
x=4
7 + 22 x 4 - 31 = 85
This is for order of operations I don’t know how to do any of this
Answer:
64
Step-by-step explanation:
7 + 22 × 4 - 31 = 64
How the answer is 64:
Use BODMAS (Bracket, Of, Division, Multiplication, Addition, Subtraction) for order of operation.
22 × 4 is first which is equal to 88
7 + 88 is next which is 95
95 - 31 is last which is 64.
The answer is 64, not 85.

A trangle has a 30 angle and a 55angle .what is the other angle ？how do you know？
Answer:
95°
Step-by-step explanation:
Sum of 3 angles of a triangle equals to 180°Here we have angles of 30° and 55°, so the remaining angle is:
180° -(30° + 55°) = 95°Based on the pattern, what are the next two terms of the sequence? 9, 15, 21, 27, . . .
Answer: The next two terms are 33 and 39
Step-by-step explanation:
9,15,21,27
First determine how you get from one value to the other.
To get from 9 to 15 you add 6.
To get from 15 to 21 you add 6 to 15.
And to get from 21 to 27 you add 6 to 21
So to get to the next term add 6 and another 6 to the value you get.
27 + 6 = 33
33 + 6 = 39

It takes 45 minutes to drive to the nearest bowling alley taking city streets going 30 miles per hour
(mph). How long will it take to get there using the freeway going 65mph if the distance is the same?
(Round to the nearest minute).
HELLLLPPPPPPP
Answer:
The time it will take to get to the bowling alley while driving at 65 mph on the freeway is approximately 20.8 minutes
Step-by-step explanation:
The given parameters are;
The time it takes through the streets to drive to the nearest bowling alley = 45 minutes
The speed of driving through the streets = 30 miles per hour (mph)
The speed of driving through the freeway to the bowling alley = 65 mph
From the speed of driving through the streets and the time taken we have;
The formula for speed, S, is S = Distance/Time
Therefore, 30 mph = Distance/45 minutes
Where, 1 hour = 60 minutes, 45 minutes = 1/60×45 hour = 3/4 hour
30 mph = Distance/45 minutes = Distance/(3/4 hour)
30 mph = Distance/(3/4 hour)
Distance = 30 mph × 3/4 hour = 22.5 miles
Given that the distance through the freeway and through the streets are the same, we have from speed = Distance/Time;
Time = Distance/Speed
The speed through the freeway = 65 mph while the distance remain 22.5 miles
Therefore;
Time = 22.5 miles/(65 mph) ≈ 0.346 hour ≈ 20.8 minutes
The time it will take to get to the bowling alley while driving at 65 mph on the freeway is approximately 20.8 minutes.

Q11. The ratio of angles of a quadrilateral are
in 3: 5:9:13. Find the angles.
Step-by-step explanation:
Let us take ratio constant as 'x'
Therefore ratio of angles
3x:5x:9x:13x
Sum of interior angles of quadrilateral is 360 degree.
3x+5x+9x+13x=sum of interior angles of quadrilateral
=>3x+5x+9x+13x=360
=>30x=360
=>x=12
Write an equation in slope-intercept form for the line parallel to y= -7x-9 that passes through the point (4,9). Show your work. Thank you :)
Answer: y=-7x + 37
Step-by-step explanation:
Parallel lines will have the same slope but different y-intercepts so again we can use the coordinates to determine the y intercept of the new equation.
So we know that the slope intercept formula is y=mx + b where m is the slope and b is the y-intercept so we will input the x and y coordinates to solve for b.
9 = -7(4) + b
9 = -28 + b
+28 +28
b = 37
The equation will be y= -7x + 37
The equation of line passes through the point (4, 9) will be;
⇒ y = - 7x + 37
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (4, 9).
And, The parallel line is,
⇒ y = - 7x - 9
Now,
Since, The equation of line passes through the point (4, 9).
So, We need to find the slope of the line.
Since, The slope of the parallel line is same.
Hence, Slope of the line is,
y = - 7x - 9
m = dy/dx = - 7
m = - 7
Thus, The equation of line with slope - 7 is,
⇒ y - 9 = -7 (x - 4)
⇒ y - 9 = - 7x + 28
⇒ y = - 7x + 28 + 9
⇒ y = - 7x + 37
Therefore, The equation of line passes through the point (4, 9) is,
⇒ y = - 7x + 37

Given segment XZ and point Y that lies on XZ, find XY if XZ = 37 and YZ = 18
Answer:
XZ=19
Step-by-step explanation:
the total length of the segment is 37, and half of the segment is 18, so to find the other half of the segment, you would subtract the half from the total amount: 37-18=19

I will give 20 Brainly points if answered within 30 minutes!!!!!!
Answer:
15 DEGREES
Step-by-step explanation:
OK SO BASICALLY, USING THE EXTERIOR ANGLES THEOREM, YOU FIND THAT 9x = 5x + something. That something is 4x so:
9x = 5x + 4x
THEN YOU FIND THAT 8x = 5x + something. That something is 3x so:
8x = 5x + 3x
4x and 3x and 5x are the interior angles of the triangle (ABC)
Then you use triangle theorem and get 4x + 3x + 5x = 180
Then: 12x = 180 and so you get x = 15
