Answer:

160

Step-by-step explanation:

Muliply both sides by 20/3 to get e=20/3*24=160

Answer:

e = 160

Step-by-step explanation:

20 * 3/20e = 24 * 20

3e = 480

3e/3 = 480/3

e = 160

Answer:

3 cups

Step-by-step explanation:

Double 1.5 to get 3.

Lara would need 3 cups of chocolate chips

The cookie recipe uses of [tex]1\frac{1}{2}[/tex] cups of chocolate chips to make 25 cookies. The ratio of chocolate chips to cookies is [tex]1\frac{1}{2}[/tex] : 25

If Lara wants to double the number of cookies she wants to make, it means she wants to make 50 cookies (25 x 2). In order to determine the cups of chocolate chips that she would need, we also need to double the cups of chocolate chips

Chocolate chips needed = [tex]1\frac{1}{2}[/tex] x 2

Convert the mixed fraction to an improper fraction

3/2 x 2

= 3 cups

A similar question was solved here : https://brainly.com/question/14379402?referrer=searchResults

Step-by-step explanation:

let the angles be ' 7x, 8x and 5x'

as we know, the sum of all the angles of a triangle is 180 degree, so,

7x + 8x + 5x = 180

20 = 180

x = 180/2

x = 90 degrees

7x = 7 × 90 = 630 degree

8x = 8 × 90 = 720 degrees

5x = 5 × 90 = 540 degrees

therefore, 5x is the smallest degrees

Answer:

The first one (Cedric is correct because he used the inverse of subtraction and added 4.5)

Step-by-step explanation:

First....I'll do it my way

z - 4.5 = -1.5

Add 4.5 on both sides

z - 4.5 + 4.5 = -1.5 + 4.5

z = 3

This should be our answer.....and so who did it right?

Cedric did

Which is the true statement?

Cedric is correct because he used the inverse of subtraction and added 4.5

y = 7

Step-by-step explanation:

9y - 7 = 56

       +7     +7

9y = 63

/9     /9

y = 7

(/9 = divided by 9)

check :  9 x 7 = 63 ( 63 - 7 = 56) correct!

Answer:

The answer is y = 4x - 1.

Step-by-step explanation:

☆The equation we'll be using: y = mx + b

☆Since we already have the slope. we have to find the y-intercept.

☆[tex]y = mx + b \\ \\ 7 = 4(2) + b \\ 7 = 8 + b \\ \frac{ - 8 = - 8 \: \: \: \: \: \: \: \: \: \: \: }{ - 1 = b \: \: \: \: \: \: \: \: \: \: } [/tex]

Answer:

He must score an 86 or more on his third test.

Step-by-step explanation:

An average is calculated by the sum of the numbers divided by the total number (#) of numbers (if that makes sense). Knowing this, we can write an algebraic equation in order to find the answer. Let x equal the unknown number.

John's previous test scores and this test score now must be at least an average of 90 or more. Therefore, the equation would be [tex]\frac{86+98+x}{3} \geq 90[/tex]. Isolate x to find the answer:

[tex]\frac{86+98+x}{3}\geq 90\\ \frac{184+x}{3} \geq 90\\184 + x \geq 270\\x \geq 86[/tex]

Therefore, he needs to get at least a 86 or higher.

Question:

[tex]5x-3y=14[/tex]

[tex]3x-5y=2[/tex]

Find x and y

Answer:

[tex]x = 4[/tex]

[tex]y =2[/tex]

Step-by-step explanation:

Given

[tex]5x-3y=14[/tex]  -- (1)

[tex]3x-5y=2[/tex] -- (2)

Required

Find x and y

We'll solve this using elimination method.

Multiply (1) by 3 and (2) by 5 to eliminate x

([tex]5x-3y=14[/tex]) * 3

([tex]3x-5y=2[/tex]) * 5

-------------------------------

[tex]15x - 9y = 42[/tex]

[tex]15x - 25y =10[/tex]

Subtract

[tex]15x - 9y = 42[/tex]

- ([tex]15x - 25y =10[/tex])

-----------------------

[tex]15x - 15x - 9y + 25y = 42 - 10[/tex]

[tex]- 9y + 25y = 42 - 10[/tex]

[tex]16y = 32[/tex]

Make y the subject

[tex]y = \frac{32}{16}[/tex]

[tex]y =2[/tex]

Substitute 2 for y in [tex]5x-3y=14[/tex]

[tex]5x - 3 * 2 = 14[/tex]

[tex]5x - 6 = 14[/tex]

Collect Like Terms

[tex]5x = 14+6[/tex]

[tex]5x = 20[/tex]

Make x the subject

[tex]x = \frac{20}{5}[/tex]

[tex]x = 4[/tex]
