Write the equation for the area of a triangle with a height that is 5 more than twice its base using one variable. Please help m
zysi [14]

Answer:

A=b(b+\frac{5}{2} )

Step-by-step explanation:

hey there!!!

we know already that the area of a triangle is given as

A=\frac{1}{2}b *h

where b= base

and h= heigth

Given that the height is 5 times more than twice it base

let h= 2b+5

Now we substitute h=2b+5 in the area of the triangle

A=\frac{1}{2}b * (2b+5)

A= \frac{2b^2}{2} +\frac{5b}{2}

A= b^2+\frac{5b}{2}\\\\A=b(b+\frac{5}{2} )

Determine whether the equation represents a direct variation. If it does, find the constant of variation. 2y=5x+1
coldgirl [10]
It does represent a direct variation.

Direct variation: y = kx
y varies directly with x

Your equation 2y = 5x + 1 is in the form of y = kx but we need to divide out the 2 from 2y so we have the following
2y = 5x + 1
2y / 2 = 5 x/ 2 + 1/2
y = 5x / 2  + 1/2
y = kx
k = 5/2
k = constant of variation = 5/2

When you add 18 to 1/4 of a number you get the number itself
JulijaS [17]
X - the number

\frac{1}{4}x+18=x \\
18=x-\frac{1}{4}x \\
18=\frac{3}{4}x \ \ \ |\times \frac{4}{3} \\
18 \times \frac{4}{3} = x \\
6 \times 4=x \\
x=24

The number is 24.
