Answer:
X would equal 4
Step-by-step explanation:
5 x 4 is 20. And the equation was 5x + 1 = 21.
So, the answer would equal 20. Hope this helped!! :D
Answer:
x=4
Step-by-step explanation:
Start with your equation: 5x+1=21
Subtract 1 on both sides: 5x=20
Divide by 5 on both sides: x=4

A ball inside of a cube has a volume of 524 cubic inches. If each side of the cube measures 12.75 inches. what is the volume of air inside the cube? (Round to the nearest tenth.)
1) 1548.7 cubic inches
2) 2072.7 cubic inches
3) 2596.7 cubic inches
4) 1048.0 cubic inches
Answer:
1548.7 in³
Step-by-step explanation:
Given that :
Volume of ball = 524 in³
Volume of a cube = s³
Where, s = 12.75 inches
Volume of cube = 12.75 * 12.75 * 12.75 = 2072.671875 in³
The volume of air inside the cube :
(volume of cube - volume of ball)
(2072.671875 - 524) in³
= 1548.671875 in³
= 1548.7 in³ (nearest tenth)
Ashik claims that the graph on the right is the correct interpretation of the scatterplot, but his friend Shelby claims that the graph on the left is correct.
Shelby’s Graph Ashik’s Graph
A graph titled Shelby's Graph has points that form a curved line. A line with negative slope is drawn. A graph titled Ashik's Graph has points that form a curved line. A curved line is drawn to connect the points.
Who is correct and why?
Shelby is correct because the line of best fit has a negative slope and the trend shows a decrease in y values as the x values increase.
Shelby is correct because the line of best fit matches the points as closely as possible with a weak correlation.
Ashik is correct because the points are a strong correlation to this nonlinear association.
Ashik is correct because points with a weak correlation can never have linear association.

What is the answer for x?
Answer:
x = 7°
Step-by-step explanation:
Sum of All angles = 180°
Form an equation
180 - 90 - 36 = 7x + 5
54 = 7x + 5
Subtract 5 from both sides
49 = 7x
x = 49/7
x = 7
Solve please. 20 points.
Answer:
336 cm^2
Step-by-step explanation:
Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.
The next one the 6X13 one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.
Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get
336 cm^2

a. 20
b. 10
c. 9
d. 8
Answer:
the answer is c. 9
Step-by-step explanation:
20=2x+2
18=2x
x=9
Answer:
C
Step-by-step explanation:
Given f(x) = 2x + 2 and f(x) = 20, then equate right sides, that is
2x + 2 = 20 ( subtract 2 from both sides )
2x = 18 ( divide both sides by 2 )
x = 9 → C

Find the slope between the two points:
(3,-2) and (-5, 2)
Answer:
the slope is -2
Step-by-step explanation:
a)3/5x + 1/x+2
can be written as a single fraction in the form ax+b/5x(x+2) where a and b are integers.
Work out the value of a and the value of b.
a =
b=
b) Factorise 4(x + y) + (x + y)^2
The value of a and b are a=8 and b=6 respectively.
What is factorization?factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.
We are given the expression as
3/(5x) + 1/(x+2)
We have to multiply 3 by (x+2) and 1 by (5x)
3(x+2) = 3x+2 and 1(5x)= 5x
Now we have
3x+6/(5x)(x+2)
5x/(5x)(x+2)
Now adding the numerators gives us
8x+6/(5x)(x+2)
Therefore a=8 and b=6

Answer:
filled in dot on -2 and shade the rest to the right (see below)
Step-by-step explanation:
This can also be read as "x is equal to or greater than -2." The "alligator" mouth, aka the inequality sign, is "eating" the x, meaning it's greater than the -2.
First graph the -2. Because it's also equal to, the dot on the -2 is filled in.
The inequality also acts as an arrow. It's pointing to the right, so the rest of the number line to the right is shaded.
This arrow method works only when the variable is on the left side so that is read "x is greater/less than a number."
circumference of circle whose radius is 7cm
Answer:

Answer:
The answer is E.) 0
Step-by-step explanation:
Please, touch some grass.
ū= (5,8)
Find the direction angle of ū.
Enter your answer as an angle in degrees between 0 and 360° rounded to the nearest hundredth.
Assuming the angle made by a vector refers to the angle it makes with the positive horizontal axis, take the dot product of u with the vector (1, 0), and recall that
a • b = ||a|| ||b|| cos(θ)
where θ is the angle made by the vectors a and b. Then
u • (1, 0) = ||u|| ||(1, 0)|| cos(θ)
We have
u • (1, 0) = 5×1 + 8×0 = 5
||u|| = √(5² + 8²) = √89
||(1, 0)|| = √(1² + 0²) = √1 = 1
so that
5 = √89 cos(θ)
cos(θ) = 5 / √89
θ = arccos(5 / √89) ≈ 57.99°
Solve for m:
598 + 15.75m < 850
Answer:

15.75m < 850 - 598
15.75m < 252
