Answer:

9/8

Step-by-step explanation:

-3/4 ÷ -8/12

Use keep, change, flip

KEEP the first fraction: -3/4 ÷ -8/12

CHANGE the division to multiplication: -3/4 × -8/12

FLIP the denominator and numerator of the second fraction: -3/4 × -12/8

Then cross multiply: -3 × -12 = 36, 4 × 8 = 32

This results in 36/32. Now you simplify from here:

36/32 = 9/8 OR 18/16 OR 27/24 OR 36/32

Let me know if I did something wrong.

What is the value of b in the equation (y)*
KonstantinChe [14]

Answer:

b = -6

Step-by-step explanation:

Apply the exponent rule that   \frac{1}{x^{n}} = x^{-n}

In this case, \frac{1}{y^{24}}  = y^{-24}

Set that equal to (y^{b})^{4}:

(y^{b})^{4} = y^{-24}

Apply the exponent rule that (x^{m})^{n} = x^{mn} so now you get:

y^{4b} = y^{-24}

Since the base is y for both sides of the equation, just set the exponents equal to each other and solve for b.

4b = -24

divide each side by 4 to get:

b = -6

Please help me solve this
Nataly_w [17]

Answer:

x = 24

Step-by-step explanation:

using the rule of exponents

a^{m} × a^{n} = a^{(m +n)}

consider left side

5^{\frac{x}{6} } × 5^{\frac{x}{2} }

= 5^{\frac{x}{6} } × 5^{\frac{3x}{6} }

= 5^{\frac{4x}{6} }

then

5^{\frac{4x}{6} } = 5^{16}

since the bases on both sides are equal, both 5 then equate exponents

\frac{4x}{6} = 16 ( multiply both sides by 6 )

4x = 96 ( divide both sides by 4 )

x = 24

Answer:

$45 after the discount

Step-by-step explanation:

Set up a proportion.

     \frac{x}{50} = \frac{10}{100}      $50 is the total amount and make the 10% a decimal

x(100) = 50(10)

100 = 500

100 ÷ 500

x = 5     <-- We have to subtract this amount from the total

$50 - $5 = $45 <-- total after the discount

<u>Hope this helps!!</u>
