Answer:
12a) 4L - 6 = Perimeter
13) 4(6x + 9)
Step-by-step explanation:
for #12: two sides of the rectangle are referred to as L
The other two sides can be referred to as L-3 (these sides are the width, which are 3 less than the length)
Perimeter = sum of all sides; so, 2L + 2(L-3)
P = 2L + 2L - 6
= 4L - 6
Answer: 12. The expression is 2L+2(L-3)
13. The answer is 6x+9
Step-by-step explanation:
12. The perimeter of a rectangle is 2*length +2*width. So, in this case (when L is the length of the rectangle) the perimeter should be 2L+2(L-3). If you simplify you will get 4L-6.
13. The perimeter is just the value you get when all the sides of a shape are added. A square has 4 equal sides. So, just divide the perimeter, which in this case is (24x+36), by 4. You should get 6x+9.

The distance from Matt’s home to school is 5/8 of a mile. He has biked 3/8 of a mile. How much further does he have to bike?
Answers
Given:
The distance from Matt’s home to school is [tex]\dfrac{5}{8}[/tex] of a mile.
He has biked [tex]\dfrac{3}{8}[/tex] of a mile.
To find:
How much further does he have to bike?
Solution:
We have,
Total distance from Matt’s home to school = [tex]\dfrac{5}{8}[/tex] of a mile.
Distance covered = [tex]\dfrac{3}{8}[/tex] of a mile.
Remaining Distance = [tex]\dfrac{5}{8}-\dfrac{3}{8}[/tex] of a mile
= [tex]\dfrac{5-3}{8}[/tex] of a mile
= [tex]\dfrac{2}{8}[/tex] of a mile
= [tex]\dfrac{1}{4}[/tex] of a mile
Matt has [tex]\dfrac{1}{4}[/tex] mile left to bike.
Therefore, the correct option is A.

Answer:
A) 1. Multiply the divisor by a multiple of 10 to create an integer divisor. 2. Multiply the dividend by the same multiple of 10 as step 1. 3. Divide, and apply the rules for dividing signed numbers.
Step-by-step explanation:
In Mathematics, divisor is the number by which the dividend should be divided.
Now, if we want to divide a decimal by another decimal, to make things easy we have to transform both numbers from decimals to integer form to make direct division easier.
The first step will be to multiply the divisor by a multiple of 10. The multiple of 10 will depend on the number of decimal places.
The second step is to do the same to the dividend.
The last step would be to divide the integers by applying rules of division of numbers.

Answer:
(15 – 22x)/4x(2x – 5)
Step-by-step explanation:
Let us take the numerator first:
(1/2x – 5) – (7/8x – 20) = (1/(2x – 5)) – (7/4(2x –5)) = (8x – 20 – 7(2x – 5))/(4(2x – 5)(2x – 5)
= (8x – 20 – 14x + 35)/4(2x – 5)² = (15 – 22x)/4(2x – 5)²
The denominator is: x/2x – 5
So we now have:
(15 – 22x)/4(2x – 5)² ÷ x/(2x – 5) = (15 – 22x)/4(2x – 5)² x (2x – 5) /X = (15 – 22x)/4x(2x – 5)

B. x= -25/12

Answers
Answer:
c. x = -1/15
Step-by-step explanation:
5/2x - 1/3 = -1/2 [multiply the whole equation by 6 (lowest common denom)
15x - 2 = -3 [add 2 on both sides of equation
15x = -1 [divide both sides by 15 to isolate x]
x = -1/15

Answers
880 were surveyed.

Multiply number of surveyed by percentage that said yes:

A) -1
B) 1/5
C) 1
D) 5
Answers
Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
y - x = 5 ( add x to both sides )
y = x + 5 ← in slope- intercept form
with slope m = 1
Parallel lines have equal slope, thus
the slope of a parallel line is m = 1 → C
Chloe charged for admission to her play on three different nights. Each night, a
different number of people were in attendance, but remarkably, Chloe collected
S541 each night. If the admission charges for each child and each adult were $9
and S17, respectively, how many people in total came to the three showings?
Answers
Answer:
The number of people in total that came to the three showings is 138 people
Step-by-step explanation:
The amount Chloe collected each night for admission to her play = $541
The admission charge for each child = $9
The admission charge for each adult = $17
The number of people attending the play each of the three nights are different
Let x represent the number of children that attend the play on the first night and ley y represent the number of adults that attend, we have;
9·x + 17·y = 541
For the second night, we have;
9·a + 17·b = 541
For the third night, we have;
9·c + 17·d = 541
27·(x + a + c) + 51·(y + b + d) = 1,623
Using Microsoft Excel, where we create a series with the first term = 541 and the common difference, d = -9 and number the adjacent column serially from 1 to 61 and the on the right column we divide the created series by 17 then we search for the whole number combinations, we get three possible combinations as follows;
12 children and 26 adults
29 children and 17 adults
46 children and 8 adults
Therefore, the number of people in total that came to the three showings = 12 + 26 + 29 + 17 + 46 + 8 = 138
The number of people in total that came to the three showings = 138 people.
The weight of an object on Mars varies directly with its weight on Earth.An object that weighs 50 pounds on mars weighs 150 on Earth.If an object weighs 120 pounds on Earths,write and solve a direct variation equation to find how much an object would weigh on mars.
Answers
Answer:
Formula: y = x/3. Answer: 40 pounds.
Step-by-step explanation:
To solve this, we divide 150 by 50. This gets us 3. This means your weight on Earth is 3x your weight on Mars. That means we can make a formula. Our formula is y (weight in pounds on Mars) = x (weight in pounds on Earth)/3. Let's plug 120 in our formula. 120/3 is 40. This means the weight of the object on Mars is 40 pounds.
