Answer:

x=51

Step-by-step explanation:

subtract 74° from 180° to get the first missing angle and then get 106°. After that, add 106° to 23° and subtract the sum (129°) from 180° to get x which equals 51°.

An inlet pipe on a swimming pool can be used to fill the pool in 40 hours. The drain pipe can be used to empty the pool in 42 ho

statuscvo [17]

Answer:

Pool will be filled in 280 hours

Step-by-step explanation:

Inlet pipe fills in 40 hours = 1 pool

Inlet pipe fills in 1 hours = $\frac{1}{40}$

Drain pipe empty in 42 hours = 1 pool

Drain pipe empty in 1 hour = $\frac{1}{42}$

If both pipes are opened together

then in pool fills in 1 hour = $\frac{1}{40}$ - $\frac{1}{42}$

on simplifying the right side ,we get $\frac{42-40}{(40)(42)}$

= $\frac{2}{(40)(42)}$

= $\frac{1}{840}$

$\frac{1}{840}$ pool fills in 1 hour

1 pool will be filled in 840 hours

$\frac{2}{3}$ pool is filled

empty pool = 1 - $\frac{2}{3}$ = $\frac{1}{3}$

therfore $\frac{1}{3}$ pool will be filled in $\frac{1}{3}$ X 840 =

= 280 hours

Find the solution of this system of equations<br> -2y = 48 + 6x<br> -6x + 9y = -84

anygoal [31]

-2y = 48 + 6x
-6x - 2y = 48 ——(1)

-6x + 9y = -84
-6x = -84 -9y ——(2)

Substitute (2) into (1):
(-84 -9y) -2y = 48
-84 -9y -2y = 48
-84 -11y = 48
-11y = 48 + 84
-11y = 132
y = - 12

Substitute y = -12 into (1):
-6x -2(-12) = 48
-6x + 24 = 48
-6x = 48 -24
-6x = 24
X = -4

ANS : y= -12, x= -4
