Answer:
60
Step-by-step explanation:
given: length = 10m + width
perimeter = 220
find length of backyard
Solution
let us assume width = x
length = 10 + width
10 + x
perimeter of rectangular backyard = 2( length + width)
= 220 = 2 ( 10 + x + x )
= 220 = 2 ( 10 + 2x )
= 220 / 2 = 10 + 2x
= 110 - 10 = 2x
= 100/2 = x = 50
so, according to above solution and Q.
width = x = 50
length = 10 + width = 10 + x = 10 + 50 = 60
So the answer is 60
Hope this helps and if I'm wrong I sincerely apologize

5m + 8 and -2m - 6. Could i get the answer and an explanation?
Answer:
m=-5
Step-by-step explanation:
Simplifying
5m + -6 = 8m + 9
Reorder the terms:
-6 + 5m = 8m + 9
Reorder the terms:
-6 + 5m = 9 + 8m
Solving
-6 + 5m = 9 + 8m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-8m' to each side of the equation.
-6 + 5m + -8m = 9 + 8m + -8m
Combine like terms: 5m + -8m = -3m
-6 + -3m = 9 + 8m + -8m
Combine like terms: 8m + -8m = 0
-6 + -3m = 9 + 0
-6 + -3m = 9
Add '6' to each side of the equation.
-6 + 6 + -3m = 9 + 6
Combine like terms: -6 + 6 = 0
0 + -3m = 9 + 6
-3m = 9 + 6
Combine like terms: 9 + 6 = 15
-3m = 15
Divide each side by '-3'.
m = -5
Simplifying
m = -5
Which shows one way the equation can be represented in words?
z minus 6 = 1.4
The difference of a number and z is the same as one and four-tenths.
A number subtracted from one and four-tenths is equal to six.
Six less than a number is the same as one and four-tenths.
Six decreased by a number is equal to one and four-tenths.
Answer:
C

6) Write a system of linear inequalities that is given by the following graph.
Answer:
The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be
⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)

Find the area of the circle with a circumference of 18.84 miles. Use 3.14 for π.
Answer:
Area = 28.25[tex]mi^{2}[/tex]
Step-by-step explanation:
Circumference formula:
C = πd
Plug in your data:
18.84mm = 3.14(d)
Divide by 3.14 to isolate for x.
18.84mm / 3.14 = d
d = 6mm

Sweety’s mother is 12 years more than twice Sweety’s age. After 8 years, she will be 20 years less than three times Sweety’s age. Find Sweety’s age and Sweety’s mother’s age?
*******x******
please show work if can
Answer: 44
Step-by-step explanation:
Let your age be x.
Then your mother's age will be 2x + 12.
After 8 years,
Your age will be x + 8.
Your mother's age will be 3(x + 8) - 20 = 3x + 24 - 20 = 3x + 4.
This is equal to 2x + 12 + 8 = 2x + 20
2x + 20 = 3x + 4
3x - 2x = 20 - 4
= x = 16
Hello again, I have another question!

35 points!!!I need help on these questions it’s a part of a common assessment.
Answer:
1) 4
2) y <= 9
3) NO SOLUTION
4) 24
5) 5 cards
Step-by-step explanation:
1st pic) 2x + 7 = 15
2x + 7 = 15
-7 -7
2x = 8
divide by 2 to isolate x
x = 4
2nd pic) y - 3 <= 6
y - 3 <= 6
+3 +3
y <= 9
3rd pic) x + 0.5 = x + 6
x + 0.5 = x + 6
-0.5 -0.5
x = x + 5.5
NO SOLUTION
4th pic) 5m + 10 <= 130
5m + 10 <= 130
-10 -10
5m <= 120
divide by 5 to isolate the m
m <= 24
5th pic) 2c - 8 > 0
2c - 8 > 0
+8 +8
2c > 8
divide by 2 to isolate the c
c > 4

Sara worked 25 hours last week. She was paid the same amount of money per hour that worked. Let h represent Sara's hourly pay. Write an algebraic expression that represents Sara's total pay last week.
Answer:
y = 25h
Step-by-step explanation:
y is the total pay she received.
25 is the amount of hours she worked, and h is the hourly pay. If she is paid $10 per hour then she will receive $250 in pay.
Answer:
If H represents Sara's hourly pay
Step-by-step explanation:
then it would be H = $250
25 and add it 10 times you get 250.

Simplify.
−6x+8/6−3/2x−1/2+5/2x
Enter your answer in the box.
Do not use decimals in your answer
Answer: =−5x+5/6
Step-by-step explanation:
Your equation:
−6x+8/6-3/2x-1/2+5/2x
Gather all the numbers with the x variable:
-6x - (3/2x) = -7 1/2x
-7 1/2x + (5/2x) = -5x
-5x is the answer to your first part.
Finally, gather all the numbers without the x variable.
(8/6) - (1/2) = 5/6
This makes your answer into -5x+5/6 ! Hope this helps :D
