Answer:
21
Step-by-step explanation:
21 + 21 = 42
42 + 12 = 54
so 21 is your answer
Answer:
21.
Step-by-step explanation:
For questions like this, it's easiest to work your way backwards from the answer to get the original number.
In this case, you subtract 12 from 54, which gives you 42 (54-12=41)
Then, you divide by 2, the opposite of "doubling". 42 ÷ 2 = 21.
Since there are no other operations, your original number is 21.
To confirm, just go through the problem again starting with 21 and seeing if you get to 54.
21, doubled (42), add 12 = 54.

A store sells mugs Each mugs cost the same amount. During a sale the store reduces of each mug by $1.75 Wen spends $28.20 on 5 mugs at the sale price what was the price of one mug before the sale
Answer: $7.39
Step-by-step explanation:
From the question, we are informed that a store sells mugs and that each mugs cost the same amount. We are further told that during a sale the store reduces of each mug by $1.75 and that Wen spends $28.20 on 5 mugs.
Since the store reduced $1.75 on each mugs, the amount that When would have paid without the discount will be:
= $28.20 + ($1.75 × 5)
= $28.20 + $8.75
= $36.95
The price of one mug before the sale will then be:
= $36.95 / 5
= $7.39
Answer:
7.39

We can split this up into 3 shapes.
Using the attached image:
[tex]A = (5-2)*(3)\\A = 3*3 = 9\\\\B = \frac{1}{2}(7-3)(5-2)\\B = \frac{1}{2}(4)(3)\\B = 2*3 = 6\\\\C = 7 * 2 = 14\\\\A + B + C = 14 + 6 + 9 = 29[/tex]

find the side length of the triangle
Answer:
19
Step-by-step explanation:
The markings on the triangle means that this is an equilateral triangle (All sides are the same length)
So, we can set the two equations we have equal to each other
4x + 7 = 3x + 10
x + 7 = 10
x = 3
Plug it into either equation
3(3) + 10 = 19

What is the range of f(x)=−3x+4
A. the set of real numbers less than 0
B. the set of real numbers less than 4
C. the set of real numbers greater than 4
D. the set of real numbers greater than 0
The range of the function f(x) = -3x + 4 is all real numbers
None of the options is correct
The given function is:
f(x) = -3x + 4
The range of a function is the set of its valid output values
The function f(x) = -3x + 4 does not have any constraint, neither does it have any value that will make the function f(x) to be undefined.
Therefore, both the domain and the range of the function is a set of all real numbers
The range of the function f(x) = -3x + 4 is a set of all real numbers

What does -B + a = 8 mean
Answer:
Step-by-step explanation:
If you're looking to find what b= Subtract a from both sides
-b=-a-8
Then divide negative 1 from both sides to equal
b=a+8
If you're looking to find what a= Add b to both sides
a=b+8
Half the value of 3x-9 is x+37. What is the value of x?
Answer:
x = 83
Step-by-step explanation:
You know that half of 3x-9 is x+37. That means 2(x+37) = 3x-9. Solve the left side of the equation. You will get 2x+74. Now the whole equation is 2x+74=3x-9. Well, move the like terms to each of their sides. You will now have 74+9 = 3x-2x. Simplify and you will get 83 = x.
Hope this helps! Please mark me as brainliest!
Answer:
x=83
Step-by-step explanation:
Since we know that half of 3x-9 is x+37, that's the same as saying the double of x+37 or 2(x+37) is equal to 3x-9. So, we can write this equation: 3x-9=2(x+37). Now, all we have to do is use simple algebra to solve the problem:
Steps Justification
3x-9=2(x+37) Original Equation
3x-9=2x+74 Distributive Property of Equality
x-9=74 Subtraction Property of Equality (Subtract 2x from both sides)
x=83 Addition Property of Equality (Add 9 to both sides)
Hope this helps!! :)

Mr. Smith has an online cooking show. Before he films an episode about baking the perfect pound cake, he prepares his ingredients. His recipe calls for 2 1 /2 cups of sugar for the cake and 1 1/ 4 cups of sugar for the vanilla glaze. How many 1 /4 -cup scoops of sugar does he need? Write your answer as a whole number, fraction, or mixed number. Simplify any fractions.
Answer:
15
Step-by-step explanation:
We are given
Mr. Smith's recipe calls for 2 1/2 cups of sugar for the cake and 1 1/4 cups of sugar for the vanilla glaze.
The total amount of sugar he would need
2 1/2 + 1 1/4
= (2 + 1) + (1/2 + 1/4)
= 3 3/4 cups of sugar.
We need this amount of sugar in 1/4 cup scoops.
This is calculated as:
let x be the number of scoops needed
x * 1/4 = 3 3/4
x* 1/4 = 15/4 ( 3 3/4 = 15/4)
x= 15
Therefore, he would be needing 15 , 1/4 cup scoop of sugar

solve the inequality 3x-3<9
Answer:
x < 4
General Formulas and Concepts:
Pre-Algebra
Equality PropertiesStep-by-step explanation:
Step 1: Define inequality
3x - 3 < 9
Step 2: Solve for x
Add 3 to both sides: 3x < 12Divide 3 on both sides: x < 4Here we see that any number x smaller than 4 would work as a solution.
Answer:
x < 4 is the answer.
Step-by-step explanation:
3x - 3 < 9 <----- This is the original question.
3x - 3 + 3 < 9 + 3 <----- Add 3 to both sides.
3x < 12 <-----Simplify
3x/3 < 12/3 <----- Divide both sides by 3.
x < 4 = x is less than 4

26) Hailey is 3 times as old as Maverick.
The sum of their ages is 48 years. How
old is Maverick?
Let H = Hailey's age and M = Maverick
Hailey is 3 times as old as Maverick: H = 3M
The sum of their ages is 48 years: H + M = 48
Since H = 3M, substitute 3M in place of H in the second equation:
H + M = 48
3M + M = 48
4M = 48
M = 12
Maverick is 12 years old. Hailey = 3M = 3(12) = 36 years old.
