Find a number such that one-half of the number is 9 less than two-thirds of the number
dimulka [17.4K]
Let's say, the number is "a"
thus        \bf \cfrac{1}{2}a=\cfrac{2}{3}a-9\implies \cfrac{a}{2}=\cfrac{2a}{3}-9\implies \cfrac{a}{2}=\cfrac{2a-27}{3}

cross-multiply and solve for "a"

sveticcg [70]

Answer:

170m

Step-by-step explanation:

The answer to the above question is letter d which is 170 m. To get the 170 m, kindly check the below solution: 

x^2 + 13x = 1764 so x = -49 and 36, we take 36 as its the positive value. And the other side is 49. Now use 2(l+b) to find perimeter. You get (36+49)*2 = 170

What is the answer i'll give brainly
egoroff_w [7]

Answer:

c = -3

Step-by-step explanation:

Multiply all terms by the same value to eliminate fraction denominators

4(-2)=4*\frac{-c-11}{4}

Cancel multiplied terms that are in the denominator

4(-2)=-c-11

Multiply the numbers

-8=-c-11

Add 11 to both sides of the equation

-8+11=-c-11+11

Simplify

3=-c

Divide both sides of the equation by the same term

\frac{3}{-1}=\frac{-c}{-1}

Simplify

c=-3
