What is the value of x in the equation -2/9x=2/5

densk [106]

Answer:

x = (-9)/5

Step-by-step explanation:

Solve for x:

(-2 x)/9 = 2/5

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (-2 x)/9 = 2/5 by -9/2:

(-9 (-2) x)/(2×9) = (-9)/2×2/5

Hint: | Express (-9)/2×(-2)/9 as a single fraction.

(-9)/2×(-2)/9 = (-9 (-2))/(2×9):

(-9 (-2))/(2×9) x = (-9)/2×2/5

Hint: | Express (-9)/2×2/5 as a single fraction.

(-9)/2×2/5 = (-9×2)/(2×5):

(-9 (-2) x)/(2×9) = (-9×2)/(2×5)

Hint: | In (-9 (-2) x)/(2×9), divide -9 in the numerator by 9 in the denominator.

(-9)/9 = (9 (-1))/9 = -1:

(-2-1 x)/2 = (-9×2)/(2×5)

Hint: | In (-(-2) x)/2, divide -2 in the numerator by 2 in the denominator.

(-2)/2 = (2 (-1))/2 = -1:

--1 x = (-9×2)/(2×5)

Hint: | Multiply all instances of -1 in -(-x).

(-1)^2 = 1:

x = (-9×2)/(2×5)

Hint: | Cancel common terms in the numerator and denominator of (-9×2)/(2×5).

(-9×2)/(2×5) = 2/2×(-9)/5 = (-9)/5:

Answer: x = (-9)/5

The graph of the function f(x)=mx+b contains the points (-1,3) and (-2,4) find m and b

inysia [295]

Answer:

m = -1; b = 2

Step-by-step explanation:

the first step in solving this equation is to find the slope

so we use the equation (y2-y1)/(x2-x1)

so with this the equation is

(4 - 3)/(-2 + 1)

then it would be 1/-1

that is -1

so the function so far is f(x) = -x + b

to find the b you would plug in the coordinates

we can plug in the first set

3 = 1 + b

b = 2

so the m is -1 and the b is 2

-18-6k=6(1+3k) <br> how do I find k

Brut [27]

Answer:

k=-1

Step-by-step explanation:

-18-6k=6(1+3k)

-18-6k=6+18k

+6k +6k

-18=6+24k

-6 -6

-24=24k

/24 /24

Answer:

d = 5

Step-by-step explanation:

Pythagorean Theorem

a^2 = b^2 = c^2

3^2 + 4^2 = 9 + 16 = 25

sqrt.25 = 5

This is important<br> to meee help

Rina8888 [55]

Answer:

I'll help you! Answer is <u>3/2</u>. It's Friday so most people aren't on Brainly doing homework lol

Step-by-step explanation:

The heaviest bag (far right) weighs 4.75 lbs, whereas the lightest bag (far left) weighs 3.25 lbs. As mixed numbers, these would be $4\frac{3}{4}$ and $3\frac{1}{4}$ . To find how much heavier the 4.75 lb bag is, you must subtract the 2 numbers.

<h3>Step 1. Convert each to a complex fraction</h3>

$4\frac{3}{4}$ = $\frac{19}{4}$

Numerator = (4 x 4) + 3 = 19
Denominator = 4 (stays the same)

$3\frac{1}{4}$ = $\frac{13}{4}$

Numerator = (3 x 4) + 1 = 13
Denominator = 4 (stays the same)

<h3>Step 2. Subtract fractions like normal </h3>

$\frac{19}{4} - \frac{13}{4} =\frac{6}{4}$

$\frac{6}{4} =\frac{3}{2}$

<h3><u>Final answer: 3/2</u> <u>(</u>Hope this helps!)</h3>
