A field is in the shape of a Rectangle. The width
of the rectangle is x yards. The length of the
rectangle is 3 more than the width. Write an
expression for the perimeter of the field.
Answer:
4x+6
Step-by-step explanation:
The perimeter of the field can be obtained by calculating the distance around the field.
in this case, we know that the shape of the field is a rectangle.
The perimeter of a rectangle can be obtained by using the formula
[tex]2(l+b)[/tex]
The width of the rectangle is given as x yards
The length of the rectangle is given as x +3 yards
Therefore, an expression to determine the perimeter of the rectangle can be given as
[tex]2(x+3+x)\\=2(2x+3)\\=4x+6[/tex]
Tell whether the angles are adjacent or vertical. Then find the value of x.

Answer:
They are adjacent. x=10/3

If f(x)=|x+7|, find f(−12).
−19
−5
5
19
Answer:
5
Step-by-step explanation:
insert f(-12) for f(x) and solve
f(-12)=|-12+7|
add -12 and 7
f(-12)=|-5|
absolute value makes it positive
f(-12)=5
If f(x)=|x+7|, the value of f(-12)=5
Given :
the function f(x)=|x+7|. Lets find out f(-12)
f(x) is an absolute function . Absolute function always gives us positive value .
for example |-6|=6
In f(-12) the value of x is -12
To find f(-12) we replace x with -12 in f(x).
[tex]f(x)=|x+7|\\f(-12)=|-12+7|\\f(-12)=|-5|\\f(-12)=5[/tex]
so, we got f(-12)=5
The answer is 5

Solve for X.
-24+6x=-6
Answer:
3
Step-by-step explanation:
start by added 24 to both sides to get
6x = 18
then divide 18 by 6 to get
x = 3
Answer:
x=3
Step-by-step explanation:
Get your constant -24 to the other side to isolate the 6x.
-24+24+6x=-6+24
6x=18
Now since the 6 is multiplied by the x to isolate the x further divide 6x by 6, make sure to divide both sides. It should look like:
6x/6=18/6
x=3
To prove the answer just plug in 3 into the orginal equation and if both sides are equal its correct.

Step-by-step explanation:
To raise money for the
music program, your
choir sells programs for
$.50 and CDs of its music
for $5 at a concert. It costs
$.15 to produce each
program and $1.75 to
produce each CD.
Everything sells for $400,
yielding a profit of $265.
How many CDs were
made?
Answer:
x = 60
y = 200
Step-by-step explanations:
Selling price:
Price of program = $0.5
Price of music = $5
Cost of production :
Program = $0.15 per program
CD = $1.75 per CD
Total Revenue = $400
Total Profit = $265
Let
Number of CD's = x
Number of program's = y
(0.5y + 5x) = 400
0.5y = 400 - 5x
y = (400 - 5x) / 0.5
y = 800 - 10x (1(
Cost of production:
1.75x + 0.15y
Profit = Total Revenue - Total cost of production
5x + 0.5y - 1.75x + 0.15y = 265
3.25x + 0.35y = 265 (2)
Put y = 800 - 10x in (2)
3.25x + 0.35y = 265
3.25x + 0.35(800 - 10x) = 265
3.25x + 280 - 3.5x = 265
-0.25x = - 15
Divide both sides by -0.25
x = -15/ -0.25
x = 60
y = 800 - 10x
= 800 - 10(60)
= 800 - 600
= 200
y = 200
Erica purchased adult and youth tickets for a movie. She bought x adult tickets for $7 each and y youth tickets for $5. Write an expression that can be used to show the total cost, C, of all tickets.
PLZ HELP IM FALING :o
i will give brainlyest
Answer:
C = 7x + 5y
Step-by-step explanation:
Algebraic Expressions
Erica purchased tickets for a movie. It's given each adult ticket cost $7 and each youth ticket cost $5.
If each adult ticket cost $7 and she bought x tickets, then she spent 7x dollars on adult tickets.
Similarly, if each youth ticket cost $5 and she bought y tickets, then she spent 5y dollars on youth tickets.
The total cost C is the sum of the individual costs, thus:
C = 7x + 5y

=−10x+1.5
Each person in a certain group supports only one of the two candidates R and T. Of the people in the group, 45 percent support Candidate R and the rest support Candidate T. How many people in the group are in favor of a flat tax
Missing Information:
Of the people in the group who support Candidate R, 58 percent are in favor of flat tax Of the people in the group who support Candidate T, 22 are in favor of a flat tax.Answer:
[tex]Total = 26.1\%N + 22[/tex]
Step-by-step explanation:
Given
[tex]R = 45\%[/tex] -- [tex]Percentage[/tex] [tex]of\ R[/tex] in the total population
[tex]Favor\ Flat\ Tax = 58\%[/tex] in group R
[tex]Favor\ Flat\ Tax = 22[/tex] in group T
Required
Determine the number of people that supports T
First, the proportion of those that supports flax rate in R needs to be calculated.
[tex]Proportion = 45\% * 58\%[/tex]
[tex]Proportion = 26.1\%[/tex]
So, those that favor flat tax rate in group R are:
[tex]Favor\ Flat\ Tax = 26.1\%N[/tex]
Where N represents the total population.
Total number of people that supports the flax tax rate is gotten by adding people that support flat tax rate in each group.
[tex]Total = Group\ R + Group\ T[/tex]
[tex]Total = 26.1\%N + 22[/tex]

Answer:
4/5
Step-by-step explanation:
The rise is 4, and the run is 5. The rise comes first, so the answer is 4/5. The line is positive.
Answer:
slope = 4/5
Step-by-step explanation:
The best way to find the slope with just a line is to pick the most direct points on the graph, meaning points that are not in between numbers but right on the graph lines
y value - y value over x value - x value
Points: (-2,0) and (3,4)
4-0 = 4
3-(-2) = 5

The costs of 1 kg apples and 1 kg grapes are in the ratio of 9:7. The cost of 1 kg apples is Rs 20 more than the cost of 1kg grapes. Find the cost of 1 kg apples and 1 kg of grapes.
Answer:
Apple = Rs90
Grape = Rs70
Step-by-step explanation:
Given
Represent Apples with A and Grapes with G
Such that:
The ratio is
[tex]A : G =9:7[/tex]
And the price is
[tex]A = 20 + G[/tex]
Required
Determine the cost of 1 kg of each fruit
[tex]A : G =9:7[/tex]
Convert to fraction
[tex]\frac{A}{G} = \frac{9}{7}[/tex]
Cross Multiply
[tex]7A = 9G[/tex]
Make A the subject
[tex]A = \frac{9}{7}G[/tex]
Substitute [tex]\frac{9}{7}G[/tex] for A in [tex]A = 20 + G[/tex]
[tex]\frac{9}{7}G = 20 + G[/tex]
Collect Like Terms
[tex]\frac{9}{7}G - G = 20[/tex]
Take LCM
[tex]\frac{9G - 7G}{7}= 20[/tex]
[tex]\frac{2G}{7}= 20[/tex]
Multiply through by 7
[tex]7 * \frac{2G}{7}= 20 * 7[/tex]
[tex]2G= 20 * 7[/tex]
Divide through by 2
[tex]\frac{2G}{2} = \frac{20 * 7}{2}[/tex]
[tex]G = \frac{20 * 7}{2}[/tex]
[tex]G = 10 * 7[/tex]
[tex]G = 70[/tex]
Substitute 70 for G in [tex]A = \frac{9}{7}G[/tex]
[tex]A = \frac{9}{7} * 70[/tex]
[tex]A = 9 * 10[/tex]
[tex]A = 90[/tex]
