Twice the difference of a number and 2 is 7.
Answer:
9
Step-by-step explanation:
-Twice means muliply by 2
-The difference of a number and 7 means subtract a number/variable and 7.
-Is equal to 9 means =9
2(X - 7) = 9
An equation to model the number is: n - 7 x 2 = 2
To find the equation, break apart the question.
twice the difference of a number and 7 equals 2. - "Twice" means we are multiplying by 2, or x 2
twice the difference of a number and 7 equals 2. "The difference of a number and 7" means we are subtracting n - 7, and this is being multiplied by 2 so we have n - 7 x 2 so far.
twice the difference of a number and 7 equals 2. "Equals two" means the equation is equal to 2, or = 2, so our equation is n - 7 x 2 = 2.

Mandy spent $287 on 7 pairs of shoes. She purchased some pairs of boots that cost $65 per pair and some pairs of workout shoes that cost
S23 per pair
Use a system of equations to help you identify how many pairs of boots (b) and workout shoes (w) Mandy bought
Enter the number of pairs of boots and workout shoes Mandy bought
Answer: Boots = 3
workout shoes = 4
Step-by-step explanation:
boots cost $65 so 65 x 3 = 195
and workout shoes cost $23 so 23 + 4 = 92 then 195 + 92 = 287
Alisa is making a design for the bottom of a dress using trapezoid shapes cut from different colors of fabric. Each trapezoid has base lengths 5 inches and 10 inches and a height of 6 inches. How much fabric does she need for 4 trapezoids?
Answer:
Well we are going to use the formula of a trapezoid.
What'd given is that two bases are 5 and 10 and the height is 6
add the two bases: 10 + 5 = 15 multiply it by 6 = 15 x 6 = 90 then divide by 2 = 45 since she is making 4 multiply it by 4,
45 x 4 = 180 fabric she needs.

Emily’s lawn grows at a constant rate. The height of her lawn, during a 10-day period, is represented by the graph below.
Based on the graph, after how many days will the lawn be 12 centimeters in height?
A) 8 days
B) 10 days
C) 16 days
D) 24 days
Answer:
I think the answer would be C 16 days.
I cant really see the bottom of the graph
Step-by-step explanation:
In 16 days Emily's lawn will achieve a height of 12 centimeters. option C is correct.
Given that,
Emily’s lawn grows at a constant rate. The height of her lawn, during a 10-day period. Based on the graph, after how many days will the lawn be 12 centimeters in height is to be determined.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The slope of the graph = Δy/Δx = 1 / 2
Now,
Equation of the height of the lawn,
y - 4 = 1/2(x)
y = 1/2x + 4
Now, for y = 12
12 = 1/2x + 4
x/2 = 8
x = 8 * 2
x = 16
Thus, In 16 days Emily's lawn will achieve a height of 12 centimeters. Option C is correct.

Find an equation of the line passing through the pair of points (4,5) and (6,9) . Write the equation in the form Ax+By=C .
Answer:
-2x + y = -3
Step-by-step explanation:
Find the slope:
9 - 5 / 6 - 4 = 4/2 = 2
Put it in point-slope form:
y - 5 = 2(x - 4)
rearrange:
y - 5 = 2x - 8
y - 2x = -3
-2x + y = -3
Which equation is true?
f(x) - 5 = g(x)
f(x) = g(x) - 5
Of(x) = g(x - 5)
Of(x - 5) = g(x)
PLZZZ HELPPP
Answer:
f(x)-5 = g(x)
Step-by-step explanation:
We translate the function g(x) down 5 units from the function f(x)
g(x) = f(x) -5
Rewriting
f(x)-5 = g(x)
Answer:
Option A
Step-by-step explanation:
f(x)-5=g(x)f(x) and g(x) are exponential functions
We can see that f(x) is shifted 5 units down
So change in y
hence 5 is to be subtracted

Suppose y varies jointly as x and z. If y=15 when x=1/2 and z=6, what is the constant of variation?
Answer:
y= 15
Step-by-step explanation:
Y= Kxz
y=6 x=1/2 z=6
15= K (1/2) (6)
15= K (3)
K= 5
SO
y= (5) (1/2) (6)
Y= 15
Answer:
k = 5
Step-by-step explanation:
Given y varies jointly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 15 when x = [tex]\frac{1}{2}[/tex] and z = 6 , then
15 = k × [tex]\frac{1}{2}[/tex] × 6 = 3k ( divide both sides by 3 )
5 = k

A tank that is 40% full contains 650 gallons of water. On a side sheet of paper, use a double number line to find the maximum capacity of the water tank.
What did you get?
gallons
Answer: max capacity is 1625 gallons.
Diagram is shown below.
=========================================================
Explanation:
We'll draw two horizontal number lines to help make a comparison or connection between percentages and tank capacity.
For the top number line, make 5 sections with the labels: 0%, 20%, 40%, 60%, 100%. The reason I'm picking 5 is because 40% = 40/100 = 2/5. So having 40% capacity means we're 2/5 full. That denominator 5 tells us how to subdivide each number line.
The bottom number line will also have 5 sections. We only know one label for this bottom portion right now. That label is 650. Place this directly under the "40%". This visually is one way to represent that 650 gallons is 40% filled. See the diagram below.
Cut the 650 in half to get 325. This corresponds to 40% cut in half to get 20%. Therefore, 325 will go under the 20%. Being 20% full means we have 325 gallons of water.
To figure out the 60% portion, we will multiply 325 by 3. This is because 3*20% = 60%, so 3*325 = 975. We'll write "975 gallons" under the "60%"
Then we have 1300 gallons under the 80% since 4*325 = 1300. Note how 4*20% = 80%, so that's where the '4' multiplier comes from.
Finally, we multiply 325 by 5 to get 1625 and that represents the full tank's capacity. Technically we could have just jumped to this directly without having to find the 60% or 80% capacity values, but it's good practice I think.
Again the diagram is shown below. The answer we're after is at the very bottom right corner. It's under the 100% to indicate the tank is completely full, or has reached max capacity.
-----------------------
Here's a way to find the answer without a double number line. This method involves setting up a proportion.
(40% full)/(650 gallons) = (100% full)/(x gallons)
40/650 = 100/x
40x = 650*100
40x = 65000
x = 65000/40
x = 1625
We confirm that the tank's max capacity is 1625 gallons.

Jesse sells advertising pages for a magazine. He is paid a 13.5% commission for each page he sells. A page sells for $1,350. He sold an average of 24 pages a month. What was his commission for the year?
Answer:
$52,488
Step-by-step explanation:
The computation of the commission for the year is as follows:
It is given that a 13.5% commission is to be paid for each page that he sold
Here the page sold for $1,350
And, he sold average of 24 pages a month
So his commission for the year is
= $1,350 × 24 × 12 × 13.5%
= $52,488

A car rental company charges $56 per day plus $0.30 per mile driven. John paid $86 after renting a car for one day. What equation should he use to find x, the number of miles he drove?
Answer:
x + 56 = 86
Step-by-step explanation:
The study of calculus is the study of change. It offers a framework for modeling dynamic systems and a method for determining the models' predictions.
Given A car rental company charges $56 per day plus $0.30 per mile driven. Since john paid 86$ after renting a car for one day. from the equation we created.
Total charges(in $) = 56 * Day + 0.30 * x(in miles)
86 = 56 * 1 + 0.30 x
x = 100miles.
Therefore john drove 100 miles.

Complete question :
Jelena has a piece of fabric in the shape of a parallelogram the height is 10 feet and its base is 16 feet because the fabric into four equal parallelograms by current base and the height in half what is the area of each new parallelogram?
Answer:
40 ft²
Step-by-step explanation:
Given that:
Height = 10 feets
Base = 16 feets
Area of parallelogram = height * base
Area of parallelogram = 10 * 16 = 160 ft²
Area of each new parallelogram :
Area of parallelogram / number of divisions
= 160ft² / 4
= 40 ft²
