Answer:
1) 80+(-20)
2) -13+9
3) -5+(8)
I don't quite know how to explain
Just think about 1) 60 is the new temperature, in order to have an addition problem we're going to have to use negative numbers. Since we had to subtract 20, in order to use addition it would be 80+(-20).
someone please help !

Cassie and her friend Molly played the balloon-pop game at the Belltown County Carnival. Cassie threw a total of 10 darts, 7 of which popped balloons. Molly threw a total of 5 darts, 4 of which popped balloons. Who had a greater ratio of darts that popped balloons to total darts?
Answer:
Molly had a greater ratio.
Step-by-step explanation:
If I were to multiply Molly's ratio by two it would give us 10:8 which is now comparable to 10:7 and 10:8 is greater than 10:7, therefore, Molly had the greater ratio. Hope this helps! Have a great day!

Answer:
5/3x - y = 5
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStandard Form: Ax + By = C
Step-by-step explanation:
Step 1: Define
Find points from graph.
x-int (3, 0)
y-int (0, -5)
Step 2: Find slope m
Substitute: [tex]m=\frac{-5-0}{0-3}[/tex]Subtract: [tex]m=\frac{-5}{-3}[/tex]Simplify: [tex]m=\frac{5}{3}[/tex]Step 3: Write Slope-Intercept Form
y = 5/3x - 5
Step 4: Find Standard Form
Subtract 5/3x on both sides: -5/3x + y = -5Multiply both sides by -1: 5/3x - y = 5And we have our answer!

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
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
Triangle CEN is congruent to Triangle CED. What property is shown by line segment CE being congruent to line segment CE?
Answer:
C. Reflexive property
Step-by-step explanation:
When a line segment is congruent or the same as itself, it is considered to have a property known as reflexive property.
This means line segment CE is a mirror image of itself. Therefore, line segment CE is congruent to line segment CE.
Line segment CE is what divides the figure given into two equal halves, making both parts congruent to each other.

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!! :)
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

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

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

WILL GIVE BRAINLIEST
Answer:d + q = 40 -----> d = 40 - q
10d + 25q = 760
Substitute!
10(40 - q) + 25q = 760
400 - 10q + 25q = 760
15q = 360
q = 24
d = 40 - 24
d = 16
