There were 40 desks in a class. The teacher wanted to arrange the desks in a rectangle with at least 4 desks in each row and column. Which of the following is a possible desk arrangement?
A) 20 rows and 20 columns
B) 5 rows and 8 columns
C) 2 rows and 20 columns
D) 7 rows and 7 columns
Answer:
B) 5 Rows and 8 Columns
Step-by-step explanation:
First you take the information from the question to know that C is wrong. This is because It has only 2 desks in rows and the question asks for 4 desks in rows and columns. Next you know that you have 40 desks so the two numbers need to multiply to 40. This makes A and D wrong, leaving your answer as B.

What is a system of equations?A set of simultaneous equations, also known as a system of equations or an equation system, is a finite set of equations for which common solutions are sought.
Given that, you buy 1 balloon and 1 banner for $4. your friend buys 3 balloons and 2 banners for $9.
Let x represents balloons and y represents banners.
Establishing the equations,
x+y = 4
x = 4 - y......(i)
3x + 2y = 9...(ii)
Put eq(i) in eq(ii)
3(4 - y) + 2y = 9
12 - 3y + 2y = 9
y = 3
Put y = 3 in eq(i)
x = 4-3
x = 1
Hence, the costs of each balloon and banner are $1 and $3 respectively.

the remaining angle for thw triangle is found by subtracting the already shown angles from 180 (the angle some of a triangle) which happens to be 96 to get 84 but now you need to subtract 84 from 180 to find the angle on the other side of line because lines have a total angle measurement of 180 but we already kbow what this get's us because it's 96 now we devide 96 by 6 to get 16 our answer.
Mia is a songwriter who collects royalties on her songs whenever they are played in a commercial or a movie. Mia will earn $50 every time one of her songs is played in a commercial and she will earn $120 every time one of her songs is played in a movie. How much would Mia earn if his songs were played in 5 commercials and 3 movies? How much would Mia earn if his songs were played in cc commercials and mm movies?
Answer:
50c + 120m represents Mia's earnings with c commercials and m movies
Mia would earn $610 with 5 commercials and 3 movies
Step-by-step explanation:
First, create an expression that represents her earnings with c commercials and m movies:
50c + 120m will represent her earnings with c commercials and m movies
Now, find her earnings with 5 commercials and 3 movies:
50c + 120m
50(5) + 120(3)
= 250 + 360
= 610
So, Mia would earn $610
Answer:
$610
Step-by-step explanation:
Ok so I would multiply $50 with 5 because it costs $50 for one commercial and there are 5 of them. You get $250 from it.
Next you multiply $120 and 3 because it costs $120 for 3 movies. You get $360.
Now you add and you get your answer which is $610.

6) a pizza is divided among John, Tim and kevon . John received 3/8 and Tim received 1/3 of the remainder. What fraction does Kevon receive? (A) 5/8 (B) 9/24 (C) 5/24 (D) 10/24
Answer:
C. 5/24
Step-by-step explanation:
John = 3/8
Tim = 1/3
Kevon = ?
---------------------------------
3/8 = 0.375
1/3 = 0.333
0.375 + 0.333 = 0.708
0.292 is left
---------------------------------
5/8 = 0.625 - wrong
9/24 = 0.375 - wrong
5/24 = 0.208333 = 0.293
10/24 = 0.416667 - wrong

What is the slope. Write the answer in simplest form.
Answer:
-1/4
Step-by-step explanation:
Points: (-8, -3), (-24, 1)
slope = rise/run = difference in y / difference in x
Find the difference in the y-coordinates in either order:
Let's do 1 - (-3) = 1 + 3 = 4
Now we find the difference in x, but it must be in the same order we did the difference in y.
-24 - (-8) = -24 + 8 = -16
Difference in y = 4
Difference in x = -16
slope = 4/(-16) = -1/4
Answer: -1/4

Answer:
a. E(a) = (a+1)²
b. E(a + h) = (a+h+1)²
c. E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h

E(z)=(z+1)²
E(a) = (a+1)²
E(a + h) = (a+h+1)²
E(a + h) - E(a) / h = (a+h+1)²- (a+1)²/h

A rectangle measures 7.08 cm by 3.2 cm.
Work out the area of the rectangle.
Answer:
22.67 cm^2
Step-by-step explanation:
The computation of the area of the rectangle is shown below:
As we know that
Area of the rectangle = Length × breadth
Here we assume the length be 7.08 cm
Or breadth be 3.2 cm
Or if we assume them inverse like length be 7.08 cm and breadth be 3.2 cm
SO the area of the rectangle is
= 7.08 cm × 3.2 cm
= 22.67 cm^2
In the both cases the answer would be the same

x=y-8;5x+y=-4
Step: Solve x=y−8for x:
Step: Substitute y−8 for x in 5x+y=−4:
5x+y=−4
5(y−8)+y=−4
6y−40=−4(Simplify both sides of the equation)
6y−40+40=−4+40(Add 40 to both sides)
6y=36
6y /6 = 36/ 6 (Divide both sides by 6)
y=6
Step: Substitute6foryinx=y−8:
x=y−8
x=6−8
x=−2 (Simplify both sides of the equation)
x=−2 and y=6
