whenever you see this kind of question you don't need to start doing all the expressions, but look at the first and last numbers of the answer, the ones that cannot be changed (have no x or y or have those that cannot be changed in this expression):

the answer can't be a or c because in the given expression we can find 3x²y² and that's the only number where we can find x²y², so it cannot be changed. (you'll have 3x²y² in the answer)

now let's look at the last digit, that doesn't have a x or a y:

in b and d we can find 2 different results so this can determine which answer is correct:

let's look back at the given expression: -7+4= -3

so the answer is b

1/6m=5/8<br> i can't slove this question<br> 8th Grade Math
murzikaleks [220]

we are given

\frac{1}{6} m=\frac{5}{8}

Since, we have to solve for m

so, we will try to isolate m on anyone side

so, firstly , we will get rid of 1/6

so, we can multiply both sides by 6

6*\frac{1}{6} m=6*\frac{5}{8}

m=6*\frac{5}{8}

now, we can simplify right side

m=3*\frac{5}{4}

now, we can multiply them

and we get

m=\frac{15}{4}...........Answer

Step-by-step explanation:

Let

x ----> amount that Jethro owes in taxes

we know that

Amount that he made last year  \$68,000

His tax rate  27\%=\frac{27}{100}

Applying proportion

\frac{x}{68,000}= \frac{27}{100}

solve for x

x=68,000(27)/100\\x=\$18,360
