The area of a triangle is 16 square units. The base of the triangle is x+4. The height of the triangle is x. Find x.
OLga [1]
The area of triangle formula is A = B*H  / 2
so it means 16 square = (<span>x+4) x /2
so x²+4x -32=0, D' = 2²- (-32)= 36, sqrt of D' = 6
so x = -2 -6 = -8 or x= -2 +6 = 4
x must be positive so x = 4</span>

What is the value of x in the equation 1/3x − 2/3 =− 18?
Klio2033 [76]

Answer:

x = -52

Step-by-step explanation:

\frac{1}{3}x-\frac{2}{3}=-18

Let us solve for x.

\frac{1}{3}x=-18+\frac{2}{3}

\frac{1}{3}x=-\frac{18*3}{1*3} +\frac{2}{3}

\frac{1}{3}x=-\frac{54}{3} +\frac{2}{3}

\frac{1}{3}x=\frac{-54+2}{3}

\frac{1}{3}x=\frac{-52}{3}

Use cross multiplication to find the value of x.

\frac{1x}{3}=\frac{-52}{3}

3*1x=3*-52

3x=-156

Divide both sides by 3.

x = - 52

Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin. Write the ratio of hours spent prac
Pavel [41]

Given:

Kelly spends 5 hours each week playing softball and 4 hours each week practicing her violin.

To find:

The ratio of hours spent practicing violin to hours spent playing softball three different ways.

Solution:

We have,

Time spend on Softball = 5 hours

Time spend on Violin = 4 hours

The ratio to hours spent practicing violin to hours spent playing softball is

\text{Required ratio}=\dfrac{\text{Time spend on Violin}}{\text{Time spend on Softball}}

\text{Required ratio}=\dfrac{4}{5}

It can be written as

\text{Required ratio}=4:5

\text{Required ratio}=4\text{ to }5

Therefore, the ratio of hours spent practicing violin to hours spent playing softball three different ways are \dfrac{4}{5}, 4:5 and 4 to 5.
