Answer:
A unit rate is a special kind of ratio, where the second number, or the denominator, is equal to one. With a unit rate, you are comparing a quantity to one. Some common unit rates are miles per gallon, price per pound, and pay rate per hour. ... Next, divide the price by the pounds so you can find the unit rate.

Write the word sentence as an equation. Then solve.
10 more than a number c is 3.
Answer:
10 +c=3
C=3-10
C=-7
.....
Answer:
c = -7
first, make the equation.
10 more than a number c is 3
the variable is c, according to the sentence.
c
"10 more than a number c"
c + 10
"10 more than a number c is 3 "
c + 10 = 3
now that you have your equation, time to solve it.
it's important to know that if you do something to an equation, as long as you do it to both sides the equation is still true.
for example.
2 + 2 = 4
if you add 1 to both sides of the equation,
2 + 2 + 1 = 4 + 1
5 = 5
this is still true.
Solving the equation.c + 10 = 3
subtract 10 from both sides of the equation.
c + 10 - 10 = 3 - 10
c = 3 - 10
c = -7

Given f(x) = -7x + 9, what is the slope and y-intercept?
Answer:
7x is the slope,9 is the y-intercept
Step-by-step explanation:
7x is the constant/unit rate,9 is what gets added after which makes the expression non-proportional.

The units of the floor plan at the right are in feet. Find the
perimeter and area of each room.
a. the kitchen
Kitchen
Bedroom
b. the bedroom
c. the bathroom
20 ft
Main
hallway
d. the closet
Closet
Bathroom
e. What is the area of the main hallway? Explain how
you could find this area using the area of each room
20 ft
Answer:
Step-by-step explanation:
a). Perimeter of the kitchen = total length of all sides
= 4 + 2 + 2 + 6 + 6 + 12 + 10 (Since side of one smallest square = 2 feet)
= 42 ft
Area of the kitchen = Area of the composite figure
= 4² + 2² + (6 × 12)
= 16 + 4 + 72
= 92 square feet
b). Perimeter of bedroom = 2(length + width)
= 2(12 + 8)
= 40 feet
Area of the bedroom = Length × Width
= 12 × 8
= 96 square feet
c). Perimeter of the bathroom = 2(9 + 4) = 26 feet
Area of the bathroom = 9 × 4 = 36 square feet
d). Perimeter of the closet = 2(6 + 8) = 28 feet
Area of the closet = 6 × 8 = 48 square feet
e). Area of the hallway = Total area of the floor plan - area of the (kitchen + bathroom + bedroom + closet)
Area of the floor plan = 20 × 20 = 400 square feet
Area of the hallway = 400 - (92 + 96 + 36 + 48)
= 400 - 272
= 128 square feet

Answer:
im pretty sure the answer is c
it is twice as likely for the next spin to land on green as opposed to red.
Explanation:
you can check your answer by multiplying 7(red) twice and you do get 14(green) as your answer.
hope this helped:)
Answer:
C.
Step-by-step explanation:
A is wrong because 5 and 4 are not the same.
B is wrong because there is a higher chance for red to spin than yellow, 7 is more than 5.
C is right because green is double as likely to spin as red, 14 is double of 7
D is wrong because 12 is less than 14
What does the word “flip” tell you to do in “keep change flip” for dividing fractions a) change the place of the numbers numerator and the denominator for the first fraction b) change the places of the numbers in the numerator and the denominator for the second fraction c) change the places of the numbers in the numerator and the denominator for both fractions d) change the ÷ between the fractions
Answer:
b) change the places of the numbers in the numerator and the denominator for the second fraction
Step-by-step explanation:
In the phrase "keep change flip":
You "keep" the first fraction.
"Change" the division sign into a multiplication sign.
"Flip" (or switch) the places of the numerator and denominator in the second fraction.
Example:
[tex]\frac{1}{2}[/tex] ÷ [tex]\frac{1}{3}[/tex]
[tex]\frac{1}{2}*\frac{3}{1}=\frac{3}{2}=1.5[/tex]

Answer:
C
Step-by-step explanation:
21 - (-5) A negative minus a negitive turns into a +
21 + 5 = 26
A. -21 + 5 = -16 NO
B. 21 - 5 = 16 NO
C. 21 + 5 = 26 YES
D. -21 - 5 = -26 NO
Answer:
C
Step-by-step explanation:
When subtracting a negative, the two negatives cancel out. The rule is that two like signs become positive.
Therefore, +(+) =+ and -(-) = +
So, the equation would be 21 + 5.

John and Jane went to a bakery to get cookies for a party. Jane bought x cookies that were $3 each. John bought x cookies that were on sale for $1 plus he got a small cake for $10.00. How much did John and Jane each spend, if they spent the same amount of money?
Answer:
They spent $15.
Step-by-step explanation:
It's given that Jane bought x cookies, so 3x.
John spent $1 on each of the x cookies he got, and also an extra $10, so x+10.
3x=x+10
2x=10
x=5
So they got 5 cookies each.
5 cookies x $3= $15 (check with $5(1)+$10= $5+$10= $15 )
Which is the first step in solving
X-2 = 2?
Answer:
The first step is to find a number that when subtracted from 2 gives you 2.
Step-by-step explanation:
The algebraic part of this problem would be to add the -2 (adding 2 to both sides) to both sides, so
first x-2=2, then x-2(+2)=2(+2) which would give us,
x=4
*note: the parenthesis are just to show that we are adding the 2, to make it more understandable.
What’s meaning of x in math
Answer:
variable
The letter "x" is often used in algebra to mean a value that is not yet known. It is called a "variable" or sometimes an "unknown". In x + 2 = 7, x is a variable, but we can work out its value if we try! A variable doesn't have to be "x", it could be "y", "w" or any letter, name or symbol.

again my sisters overdue test someone pls just help I’m doing my math and art homework and can’t help her jggvgrcrvgb
Answer:
She should get $23.6 in change
Step-by-step explanation:
You add the two items she bought which makes up $89.94, then you subtract the discount of $13.50, which leaves you with 76.44 to pay. If you pay with a 100 dollar bill, you subtract 76.44 from 100 in order to find out how much change you recieve.
Answer:
Step-by-step explanation:
100-((39.95+49.99)-13.50)=
100-(89.94-13.50)=
100-76.44=
23.56
You have to add the amount she is paying for the total then subtract that by the discount. Then subtract how much she gave them by the cost to get the change!
Which of the following rules describes the function graphed below? On a coordinate plane, points are at (1, 5), (2, 4), (3, 3), (4, 2). a. Output = Input c. Output = 5 · Input - 4 b. Output = Input - 4 d. Output = 6 - Input Please select the best answer from the choices provided A B C D
*see attachment
Answer:
D. Output = 6 - Input
Step-by-step explanation:
The output is the y-value, while the input is the x-value. The coordinates are represented as (x, y), and are graphed in the figure attached below.
Let's consider the function and see which rule best describes the function.
Considering the point (1, 5), the rule, output = 6 - input, applies.
Let's check it out:
Output is 5, input is 1. Substitute 1 as input into the rule, Output = 6 - input, and see if it would give you 5 as output:
Output = 6 - 1
Output = 5
If you try another coordinate pair of the function, the same rule will apply.
Therefore, the best answer is D. Output = 6 - Input
