X/72 = 135/90 what is x?

1 answer:

5 0

Hey! I'll provide the steps required.

First, solved the proportion by cross multiplication.

$X(90) = (135)(72)$

Then use the commutative property to reorder the terms as well as multiply the numbers.

90x = 9720

Finally, divide it by 90.

x = 108

Answer:

Answer in explanation.

Step-by-step explanation:

Lets take

$y = \frac{3}{4} x - 5$

as L1.

Take L2 the line perpendicular to L1.

Standard form of equation of line:

y=mx+c, where m = slope and c = y-intercept.

Since L1 and L2 are perpendicular,

mL1 x mL2 = -1

Substitute mL1 into the equation,

3/4 x mL2 = -1

mL2 = -1 ÷ 3/4

mL2 = -4/3

L2 : y = mx+ c

Substitute y = 6, x = 8 and m = -4/3 into the equation,

$6 = - \frac{4}{3} (8) + c \\ 6 = - \frac{32}{3} + c \\ c = 6 + \frac{32}{3} \\ = 16 \frac{2}{3}$

therefore L2:

$y = - \frac{4}{3}x + 16 \frac{2}{3}$

Lets take L3 as the line parallel to L1.

Since L3 and L1 are parallel,

mL3 = mL1 = 3/4

equation of line: y = mx+c

substitute y = 6, x = 8 and m = 3/4 into equation.

$6 = ( \frac{3}{4} )(8) + c \\ 6 = 6 + c \\ c = 6 - 6 \\ = 0$

therefore L3:

$y = \frac{3}{4} x$

the sum of Ages of two brother is 18the elder brother is 10 years older than younger brother then what are the ages of those bro

NemiM [27]

Answer:

Age of younger brother is 4 years..

And age if elder brother is 14 years.

Step-by-step explanation:

Let us denote 'x' as the age of smaller brother,

then, the age of younger brother will be x+10 years.

x+x+10 = 18

2x+10 = 18

2x = 18-10

2x = 8

x = 8/2

x = 4

Age of younger brother is 4 years.

Age of elder brother = x + 10

= 4 + 10

= 14 years.
