Divide. Write your answer in simplest form. 6/7 ÷ 5/21

1 answer:

5 0

The answer is 8/5.
To divide fractions, flip the second fraction and multiply.
For example,
= 6/7 • 21/5
= 126/35
Simplify by dividing both sides by 7 to get your answer.
= 8/5

HELP ASAP !!

Aleks [24]

Answer:

Step-by-step explanation:

total money = $2.25 = 225 cents

types of denomination in coins or cents are dimes and nickels

dime = 10 cents , nickel = 5 cents

twice of dimes to nickels

let no of dimes = x and no of nickels = y

our equation

10x + 5y = 225

x = 2y

10(2y) + 5y = 225

20y +5y = 225

25 y = 225

y=9

x =2y 2x9 = 18

so the number of dimes = 18 and nickels = 9

cross verification:

10x18 + 5x9 = 180 +45 = 225

There is a line whose Y intercept is -5 and whose slope is 0. What is its equation in slope – intercept form?

Aleonysh [2.5K]

<h2>Key Concepts</h2>

Linear equations
Slope-intercept form

Slope-intercept form looks like this: $y=mx+b$

<em>m</em> = slope
<em>b</em> = y-intercept

<h2>Solving the Question</h2>

We're given:

<em>m</em> = 0
<em>b</em> = -5

Plug the given values into y=mx+b:

$y=0x-5\\y=-5$

<h2>Answer</h2>

$y=-5$

Write an equation in slope intercept form of the line that passes through the given points (-3, 3) and (1,2) HELP

zhannawk [14.2K]

Answer:

The answer is $y = - \frac{1}{4} x + \frac{9}{4}$

Step-by-step explanation:

❃Incase you forgot what the slope-intercept formula is ☟

$y = mx + b$

❃Incase you also forgot, what the slope formula is ☟

$m = \frac{y_2 - y_1}{x_2 - x_1}$

☆ First: We are going to be solving for the slope.

$m = \frac{2- 3}{1 - ( - 3)} = \frac{ - 1}{4} = - \frac{1}{4}$

☆Second: We are going to find the y-intercept.

$y = mx + b \\ 3 = - \frac{1}{4} ( - 3) + b \\ 3 = \frac{3}{4} + b \\ \frac{ - \frac{3}{4} = - \frac{3}{4} \: \: \: \: \: \: \: \: \: \: \: }{ \frac{ 9}{4} = b \: \: \: \: \: \: \: \: }$

☆Third: Plug in.

$y = - \frac{1}{4} x + \frac{9}{4}$
