Answer:
x = 400
Step-by-step explanation:
Let 15% of x is equal to 60.
We can find it as follows :
[tex]15\%\ of\ x=60\\\\\dfrac{15x}{100}=60\\\\x=\dfrac{60\times 100}{15}\\\\x=400[/tex]
So, 15% of 400 is equal to 60.

The length of a rectangle is 13 centimeters less than its width. What are the dimensions of the rectangle if its area is 140 square centimeters?
Answer:
Dimensions = 7 cm by 20 cm.
Step-by-step explanation:
Let the length and width of the rectangle be L & W respectively.
Given the following data;
Area of rectangle = 140 cm²
L = W - 13
To find the dimensions of the rectangle;
The area of rectangle = L * W
Substituting into the above formula, we have;
140 = L * W
140 = (W - 13) * W
140 = W² - 13W
W² - 13W - 140 = 0
Solving the quadratic equation using factorization method;
Factors are -20 and 7
W² - 20W + 7W - 140 = 0
W(W - 20) + 7(W - 20) = 0
(W - 20)(W + 7) = 0
W - 20 = 0
W = 20
W + 7 = 0
W = -7
Thus, W = 20 or -7
But the width has to be positive, W = 20 centimeters.
Next, to find the length of rectangle
L = W - 13
L = 20 - 13
L = 7 centimeters.
Ms. Joseph has 6 tables ready for her 24 art students to make posters. The students do not all fit at the tables, so Ms. Joseph sets up 2 more tables. The students share the tables evenly. How many students are at each table now?
Answer:
There are 3 students at each table
Step-by-step explanation:
If Ms. Joseph has 6 tables to begin with and she sets up 2 more that is 8 tables in total. 24 divided by 8 is 3. So there are 3 students at each table.

Solve this equation h + 17 = 40
Thanks!
Answer:
H= 40-17
H= 53
Therefore, h=23
Answer:
h=23
Step-by-step explanation:
Since h plus 17 is equal to 40, h needs to be a number that adds to 17 to get 40. Therefore, you can subtract 17 from 40 to get 23. If you add it into the equation you get 23+17=40 which is correct.

Step-by-step explanation:
First we calculate the obvious square without the extra points. The side length of the square is four; therefore, the area of the square is 16 square units. The points are each 1 square unit as they split the squares down the midde. In total, 16 + 4(1) = 20.

WILL GIVE BRAINLIEST FOR CORRECT ANSWER: All 5 students in Mrs.Awful's class score 50 on a test. What is the class's average score on this test?
Answer:
50
Step-by-step explanation:
If everyone scored 50, the average is just 50.
The math would also be:
50 + 50 + 50 + 50 + 50 / 5 = 250 / 5 = 50
Answer:
50
Step-by-step explanation:
In short explanation, since all the students scored the same score, the average will be the that score
Since all students scored 50, the average will be 50.
Proof:
[tex]50 + 50 + 50 + 50 + 50 = 250[/tex]
[tex]250 \div 5 = 50[/tex]

What is the total interior measure of the polygon?
And what’s the value of x?
Answer:
x =196°
Step-by-step explanation:
The polygon is 5 sided, therefore, total interior angles of a pentagon is:
(n - 2) 180
(5 - 2) 180
(3) 180
540°
96° + 112° + 102° + 84° + x° = 540°
394° + x = 540°
Collect like terms
x = 540° - 394°
x = 196°
2) A landscaping company charges $40 to mow a lawn and $15 per hour to mulch the flower beds. Write an equation to represent the amount paid to the landscaping, A, to mow the lawn and mulch the flower beds for H hours.

Diego and Jada are both trying to write an expression with fewer terms that is equivalent to
7a+5b−3a+4b
Jada thinks 10a+1b is equivalent to the original expression.
Diego thinks 4a+9b is equivalent to the original expression.
Substitute your own values for “a” and “b” and determine if the expressions are equivalent. Show your work in the space provided.
Answer:
Diego's answer 4b+9b is correct:)
Step-by-step explanation:
Our first step is to combine like terms.
Causing you to combine 7a and -3a which gives you 4a because 7-3=4
Next, you would combine 5b and 4b which gives you 9b because 5+4=9
After you have combined like terms you would have your simplified equation 4b+9b causing Diego's answer to be correct!
Hope this helps!
