Step-by-step explanation:

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:

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:

a or c

Answer:

148 cm^2.

Step-by-step explanation:

It has 2 surfaces of area 5*6, 2 of  5*4 and 2 of 4*6.

= 2*30 + 2*20 + 2*24

= 60 + 40 + 48

= 148 cm^2.

Answer:

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:

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

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]

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]

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

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.
