To solve this problem you could set up a proportion 1/20=6.75/x. Next you would use property of cross products to get 20*6.75=x. Just mulitply to solve you should get 135 inches. To find the answer in ft just divide by 12

Pls help i dont get how to do this

Lorico [155]

Step-by-step explanation:

What this is saying is...20 is a whole number; but 3/4 is not. What they are saying is, if you have to add a mixed number with a whole number, you can add both of the whole numbers together. Then, you add the 3/4 at the end...because it is not a whole number. You can break apart a mixed number by separating the whole number and the fraction.

Hope this helps :)

Y=-2x-21 determine the intercepts of the line (,) (,) ASAPPPP

Nesterboy [21]

Answer:

x intercept (10.5,0)

y intercept (0, -21)

Step-by-step explanation:

y=-2x-21

there are two intercept for a line

x intercept, the point of given equation of line which lies on x axis.

For x intercept corodinate of y is o

Thus, value x intercept is form (x,0)

putting these value in y=-2x-21, we find x intercept

0=-2x-21

2x = 21

x = 21/2 = 10.5

Thus, x intercept (10.5,0)

Y intercept, the point of given equation of line which lies on y axis.

For Y intercept coordinate of x is o

Thus, value y intercept is form (0,y)

putting these value in y=-2x-21, we find y intercept

y = -2*0 -21

y = -21

Thus, y intercept (0, -21)

Please help. solve for x

malfutka [58]

Step-by-step explanation:

Given,

Base of the triangle

$2 \sqrt{6}$

Hypotenuse of the triangle = 5

Height of the triangle = x

Therefore, According to Pythagoras Theorem,

${base}^{2} + {height}^{2} = {hypotenuse}^{2}$

$= > {(2 \sqrt{6)} }^{2} + {x}^{2} = {5}^{2}$

$= > 24 + {x}^{2} = 25$

$= > {x}^{2} = 25 - 24$

$= > {x}^{2} = 1$

$= > x = \sqrt{1}$

$= > x = 1$

Hence, the required value of <u>x is 1.</u>
