Step-by-step explanation:
whenever you see a variable ( a letter ) without a number in front of it, add a 1 ! It means the same thing...
y is the same as 1y
1). 3y + y = ?
Add that 1!
3y + 1y = ?
This problem is the same as 3 + 1
3y + 1y = 4y
2). b + b = ?
Add those 1's !
1b + 1b = ?
this is the same as 1 + 1
1b + 1b = 2b
Remember to keep the variable !
Part B is like a puzzle and the instructions give us hints.
It is telling us, when we see an r, we replace it with the number 3
and when we see t , we replace it with the number 9
Let's solve these puzzles!
8). [tex]\frac{r}{t} = ?[/tex]
We see and r and a t, let's plug in 3 and 9
Now we have ...
[tex]\frac{3}{9} = ?[/tex]
Divide using a calculator!
We get ....
[tex]\frac{3}{9} = \frac{1}{3}[/tex] or 0.33
9). [tex]rt = ?[/tex]
When variables are right next to each other, this means they are being MULTIPLIED!
Let's replace r and t with 3 and 9 and multiply them together!
[tex]rt =[/tex] 3 × 9
3 × 9 = 27
We do similar things for Part C
12). [tex]ab = ?[/tex]
It tells us a = 5 and b = -4
Let's plug it in
[tex]ab =[/tex] 5 × -4
5 × - 4 = -20

the rectangle.

Answer:
length: 24 ftwidth: 42 ftStep-by-step explanation:
The area is the product of length and width. If L represents the length, then the width is (2L -6), and the area is ...
L(2L -6) = 1008
L² -3L -504 = 0 . . . . . divide by 2, put in standard form
(L -24)(L +21) = 0 . . . . factor
L = 24 . . . . makes the first factor zero
W = 2L -6 = 2(24) -6 = 42
The length of the rectangle is 24 feet; the width is 42 feet.

Answer:
x ≈ 17.14
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{12}{x}[/tex] ( multiply both sides by x )
x × tan35° = 12 ( divide both sides by tan35° )
x = [tex]\frac{12}{tan35}[/tex] ≈ 17.14 ( to the nearest tenth )

eight times the reciprocal of a number equals 4 times the reciprocal of 2. find the number
Answers
Answer:
The number is 4
Step-by-step explanation:
Let the number = 'x'
Reciprocal of 'x' = 1/x
Reciprocal of 2 = 1/2
8 times the reciprocal of 'x' = [tex]8*\frac{1}{x}\\[/tex]
[tex]8*\frac{1}{x}= 4* \frac{1}{2}\\\\8*\frac{1}{x}= 2\\[/tex]
Now multiply both sides by x
[tex]8*\frac{1}{x}*x = 2*x\\\\8 = 2x[/tex]
Now divide both sides by 2
[tex]\frac{8}{2}=\frac{2x}{2}\\\\4 = x[/tex]
x = 4

Ella's lunch cost? Select the correct solution method, using x to represent the
cost of Ella's lunch.
A.
NIX
= 6. Multiply both sides by 2. Ella's lunch cost $12.
B. 2x = 6. Divide both sides by 2. Ella's lunch cost $3.
C. x + 2 = 6. Subtract 2 from both sides. Ella's lunch cost $4.
O D. X-2 = 6. Add 2 to both sides. Ella's lunch cost $8.
Answers
Answer:
D
Step-by-step explanation:
Because it says Klay lunch cost is $2 less than Ella's.
==> Ella's - $2 = Klay's
==> x-2=6
plus both side by 2
so the answer is $8
Find the areas of the figures below. Show all work on for each problem.
Answers
Answer:
310 in²
Step-by-step explanation:
Area of the figure = area of the larger rectangle + area of the medium rectangle + area of smaller rectangle
✔️Area of the larger rectangle = L*W
L = 20 in
W = 7 in
Area = 20*7 = 140 in²
✔️Area of the medium rectangle = L*W
L = 20 - 2 = 18 in
W = 22 - (10 + 7) = 5 in
Area = 18*5 = 90 in²
✔️Area of the smaller rectangle = L*W
L = 8 in
W = 10 in
Area = 8*10 = 80 in²
✅Area of the figure = 140 + 90 + 80 = 310 in²

What is the fraction?In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.
Let the unknown number be x.
Here, 1/3 = x/12
Multiply both the numerator and denominator of 1/3 by 4, we get
4/12
So, 4/12 = x/12
x=12
Therefore, the unknown number is 12.
