Natalie bought a 3 - pack of erasers for $1.47. How much did each eraser cost?

Answers

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.

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

Answers

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]

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.

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

Triangle Sum Theorem CLASSWORK

Answers

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]
