3x + 8 = 2x + 21
Answer:
Step-by-step explanation:Simplifying
3x + 8 = 2x + -21
Reorder the terms:
8 + 3x = 2x + -21
Reorder the terms:
8 + 3x = -21 + 2x
Solving
8 + 3x = -21 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
8 + 3x + -2x = -21 + 2x + -2x
Combine like terms: 3x + -2x = 1x
8 + 1x = -21 + 2x + -2x
Combine like terms: 2x + -2x = 0
8 + 1x = -21 + 0
8 + 1x = -21
Add '-8' to each side of the equation.
8 + -8 + 1x = -21 + -8
Combine like terms: 8 + -8 = 0
0 + 1x = -21 + -8
1x = -21 + -8
Combine like terms: -21 + -8 = -29
1x = -29
Divide each side by '1'.
x = -29
Simplifying
x = -29
3x + 8 = 2x + 21
3x - 2x + 8 = 21
x + 8 = 21
x = 21 - 8
x = 13

To make a base for a jar of handmade cream, Barbara needs 3 tablespoons of coconut butter for every cup of beeswax. Which statement below is TRUE about this scenario?
a) The ratio of a jar of handmade cream to coconut butter is 3:1.
b) The ratio of beeswax to coconut butter is 3 to 1.
c) The ratio of beeswax to coconut butter is 1 to 3.
d) The ratio of coconut butter to beeswax is 1 to 3.
Answer:
c) The ratio of beeswax to coconut butter is 1 to 3.
Step-by-step explanation:
A ratio can be defined as a mathematical expression used for the comparison of two (2) values or quantities.
Basically, a ratio gives the relationship between two values or quantities by comparing them together. It is typically written in the form; x : y
In this scenario, to make a base for a jar of handmade cream, Barbara needs 3 tablespoons of coconut butter for every cup of beeswax. The statement which is true about this scenario is that, the ratio of beeswax to coconut butter is 1 to 3.
Given the following data;
Amount of coconut butter (X) = 3 tsp
Amount of beeswax (Y) = 1 cup
The ratio of beeswax to coconut butter is;
Y : X = 1 : 3
Hence, the ratio of beeswax to coconut butter is 1 to 3.

Henry makes $12.50 per hour for the first 40 hours he works in a week. For 5 points
each additional hour he makes $18 per hour. How much did he make if he
worked 44 1/2 hours last week? *
Answer:
He made $581 if he worked 44 1/2 hours last week
Step-by-step explanation:
Let us solve the question
∵ Henry makes $12.50 per hour for the first 40 hours
∵ For each additional hour, he makes $18 per hour
→ We need to find how much he made if he worked 44 1/2 hours
→ At first, find his earning for the first 40 hours
∵ His earning in the first 40 hours = 40 × 12.50
∴ His earning in the first 40 hours = $500
→ Find how many hours he worked after the first 40 hours
∵ 44 1/2 - 40 = 4 1/2 hours
∴ He worked 4 1/2 hours over the first 40 hours
→ Find his earning from them
∵ His earning in 4 1/2 hours = 4 1/2 × 18
∴ His earning in 4 1/2 hours = $81
→ Now add the two amounts to find his total earning
∵ His total earning = 500 + 81
∴ His total earning = $581
∴ He made $581 if he worked 44 1/2 hours last week

There is an initial fee to join a gym, plus a
monthly charge. The table represents the linear
relationship between the total cost of joining
the gym and the number of months a person is
a member. What is the y-intercept of the line,
and what does it represent in this situation?
I took a pic of the table
Answer:
the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.
Step-by-step explanation:
Using, the formula y1+y2/x1-x2,
Choosing any two points, make the expression:
1-2/125-155
simplify:
-1/-30
the slope of the equation is -1/-30.
to find y intercept, using the function y=mx+b, plug in the slope and one of the two points that you used:
y would be 2
x would be 155
b is the y intercept
2= -1/-30•155 + b
2=5⅙+b
b = - 3⅙
the equation of the line is y = -1/-30 - 3⅙ and the y intercept is -3⅙.
What would be the answer for 75 X 152
Answer:
75 x 152 = 11,400.
Step-by-step explanation:
75 times 152 equals 11,400. You can find this by using a calculator, or you can multiply it out by hand. There's lots of videos on how to multiply things by hand, if you wanted to learn how. Hope this helps! :)

Evaluate 0.1m + 8- 12n when m=30 and n = 1/4 answer
Answer:
8
Step-by-step explanation:
Original equation:
0.1m + 8 - 12n
Plug in the values of m and n
0.1(30) + 8 - 12(0.25)
Multiply.
0.1 x 30 = 3
3 + 8 - 12(0.25)
Multiply.
-12 x 0.25 = -3
3 + 8 - 3
Add.
3 + 8 = 11
11 - 3
Subtract.
11 - 3 = 8
