Answer:
y=6
Step-by-step explanation:
y=3x x=2
y=3(2)
y=6
For the given expression, the value of y is 6.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ y = 3x

Natalie bought a 3 - pack of erasers for $1.47. How much did each eraser cost?
Answer:
Each eraser costs $0.49
Step-by-step explanation:
If three erasers cost $1.47, and you have to find the value of one eraser, all you have to do is divide $1.47 by three.
1.47 ÷ 3 = 0.49
To prove this, you can multiple 0.49 by three.
0.49 × 3 = 1.47
Therefore, your answer will be $0.49 per eraser.
(Remember to add the money symbol because some hardcore teachers won't accept the answer without it, or will deduct points. The symbol looks like this: $)
Answer:
$0.49
Explanation:
1.47 divided by 3 is 0.49.

Volume Of Cylinder :
π r² .Here , the radius of the cylinder is given as 70 cm and the volume is 1.54 m³ .
Converting ;
1 m³ = 1 × 10⁶ cm³ .> 1.54 × 10⁶ cm³ .> 1540000 cm ³.> π r² h = 1540000> 22/7 × 70 × 70 × h = 1540000> 22 × 10 × 70 h = 1540000> 15400 h = 1540000> h = 100 cm = 1 m.The height of the cylinder is 100cm.=1m.
PLEASE HELP i have to turn this in in an hour PLEASE DONT GUESS
Answer:
x = 29°
Step-by-step explanation:
the Δ on the right has 3 angles whose measures are 30°, 74°, and 76° (you get 76° because it forms a linear pair with an angle that is 104°; you get 74° by adding 30 and 76 and subtracting the sum from 180°.
the Δ on the left has 3 angles whose measures are 45°, 29°, and 106° (you get 106° because it forms a linear pair with an angle that is 74°; you get 29° by adding 45 and 106 and subtracting the sum from 180°.
∡x is a vertical angle with the angle that measures 29° and vertical angles are congruent
Answer:
hopw this helps!!!!!!! so this means that x = 29 :) hoep t∡x is a vertical angle with the angle that measures 29° and vertical angles are congruent

Triangle Sum Theorem CLASSWORK
Step-by-step explanation:
Sum of angles in a triangle = 180°.
Question 3:
We have 90° + 61° + (14x + 1)° = 180°.
=> 14x° + 152° = 180°
=> 14x° = 28°
=> x = 2.
Question 4:
We have 70° + 55° + (4x + 3)° = 180°.
=> 4x° + 128° = 180°
=> 4x° = 52°
=> x = 13.
Answer:
[tex](14x + 1) + 90 + 61 = 180 \\ 14x + 152 = 180 \\ 14x = 28 \\ \boxed{x = 2}[/tex]
2 is the right answer.[tex](4x + 3) + 55 + 70 = 180 \\ 4x + 128 = 180 \\ 4x = 52 \\ \boxed{x = 13}[/tex]

The weight y of an object on Titan, one of Saturn's moons, is proportional to the weight
x of the object on Earth. An object that weighs 105 pounds on Earth would weigh 15
pounds on Titan. How much would a spacecraft that weighs 3500 kilograms on
Earth weigh on Titan?
Answer:
The spacecraft would weigh 500 kilograms on Titan.
Step-by-step explanation:
An object that weighs 105 pounds on Earth would weigh 15 pounds on Titan.
This means that the weighs on Titan are 105/15 = 7 times less than the weighs on Earth.
How much would a spacecraft that weighs 3500 kilograms on Earth weigh on Titan?
3500/7 = 500 kilograms
The spacecraft would weigh 500 kilograms on Titan.

Name two ways that saving and investing are different
I hate these plz help again
Answer and Step-by-step explanation:
We can eliminate answer choices 2 and 4, since the graphs are shading below the line, which means y is less than or less than or equal to the values.
The answer is the first answer choice.
This is because this inequality matches up with the graph.
Everything is shaded below, and y is less than, so it matches up.
3 is the y-intercept.
The slopes match up as well.

Find the area of the following shape:
Answer:
30 cm
Step-by-step explanation:
the area is 1/2 base x height
so (1/2)x10 x 12
Answer:
60 cm squared
Step-by-step explanation:
The 13 cm is just to distract you.
The formula for calculating a triangle is (base x height)/2.
The base is 10 cm, and the height is 12 cm.
Then you plug in the numbers.
(10 x 12)/2=60 cm squared.

Tatiana is buying b number of books and m number of magazines at the book fair. The books cost $4 each and the magazines cost $2 each. Tatiana's total purchase can be shown with this expression: 4b+2m. Which
expression is equivalent to 4b+2m
Answer:
[tex]4b + 2m = 2(2b + m)[/tex]
Step-by-step explanation:
Given
[tex]4b + 2m[/tex]
Required
Write an equivalent expression
To do this, we simply write [tex]4b + 2m[/tex] as a product of two factors.
Express 4b as 2 * 2b
[tex]4b + 2m = 2 * 2b + 2m[/tex]
Express 2m as 2 * m
[tex]4b + 2m = 2 * 2b + 2 * m[/tex]
Factor 2 out of the expression:
[tex]4b + 2m = 2 *(2b + m)[/tex]
[tex]4b + 2m = 2(2b + m)[/tex]
Hence:
An equivalent expression is: [tex]2(2b + m)[/tex]
What are the solutions to x2 – 10x = 39?
Answer: x=−3 or x=13
Step-by-step explanation:
Step 1: Subtract 39 from both sides.
x2−10x−39=39−39
x2−10x−39=0
Step 2: Factor left side of equation.
(x+3)(x−13)=0
Step 3: Set factors equal to 0.
x+3=0 or x−13=0
x=−3 or x=13
