Answer:

$\large\boxed{x=\dfrac{8}{9}}$

Step-by-step explanation:

$9x-8=0$ <em>add 8 to both sides</em>

$9x-8+8=0+8$

$9x=8$ <em>divide both sides by 9</em>

$\dfrac{9x}{9}=\dfrac{8}{9}\\\\x=\dfrac{8}{9}$

The residence of a city voted on whether to raise property taxes the ratio of yes votes to no votes was 7 to 4 if there were 367

Tresset [83]

Answer: 10,098 votes

Step-by-step explanation:

The ratio is 7 : 4 which means that for every 7 yes votes, there were 4 no votes.

To find the total votes, add the ratios:

= 7 + 4

= 11

4/11 are the no votes out of the total. Assuming the total is x, the formula is:

4/11x = 3,672

x = 3,672 / 4/11

x = 10,098 votes

Make a 8 1/3 a faction then make it into simplest form and then explain PLS HELP ME

horsena [70]

Answer:

2 2/3

Step-by-step Explanation:

You can make the 8 1/3 a fraction by making the whole number 8 into a fraction by putting 8 as the numerator and 1 as the denomenator and then multiply 8/1 by 1/3 to get 8/3. You can then simplify this even further by making this improper fraction into an mixed fraction. 3 goes into 8, 2 times with a remainder of 2. You then write the remainder as 2 over 3 to make the fraction 2/3. This then comes out to be 2 2/3.

8/1 • 2/3 = 8/3

8/3 = 2 2/3

Rewrite the expression with rational exponents as a radical expression.

nexus9112 [7]

Answer:

If the expression is $4x^\frac{3}{7}$ , then the answer is the first option.

If the expression is $(4x)^\frac{3}{7}$ , then the answer is the third option.

Step-by-step explanation:

Remember that when you have a radical expression in the form $\sqrt[n]{x}$ , you can rewrite as:

$=x^\frac{1}{n}$

Then:

- If the expression is $4x^\frac{3}{7}$ , then you can rewrite it in the following radical form:

$=4\sqrt[7]{x^3}$ (This form matches with the first option.)

- If the expression is $(4x)^\frac{3}{7}$ , then you can rewrite it in the following radical form:

$=\sqrt[7]{(4x)^3}$ (This form matches with the third option).

a polynomial function has -5<img src="https://tex.z-dn.net/?f=%5Csqrt%7B3t%7D" id="TexFormula1" title="\sqrt{3t}" alt="\sqrt{3t}

Goshia [24]

Answer:

$5 \sqrt{3}i$

Step-by-step explanation:

Assuming one root of a polynomial function is

$- 5 \sqrt{3} i$

Then the other root is

$5 \sqrt{3}i$

The reason is that , complex roots of polynomial functions occur in pairs.

One complex root is the conjugate of the other.

This means that, if

$x - yi$

is a root, then

$x + yi$

is also a root.

You are trying to recreate flubber because you are obsessed with that movie and you thought it was the coolest. you take 70% sli

german

Let $x$ be the amount (gal) of the 40% slime solution you end up using. You want to end up with 120 gal of the 50% solution, so that you would use $120-x$ gal of the 70% solution.

You want the final solution to consist of 50% slime, or 60 gal of slime. Each gal of the 40% solution contributes 0.4 gal of slime, while each gal of the 70% solution contributes 0.7 gal of slime. This means

$0.4x+0.7(120-x)=0.5\cdot120=60$

$\implies0.4x+84-0.7x=60$

$\implies24=0.3x$

$\implies x=80$

so the answer is B.
