Substitute x with (-2) and y with (-4)<br> Simplify: 5(41 - x) + {-7(y + x)} =

kkurt [141]

Answer:

$257$

Step-by-step explanation:

We want to evaluate:

$5(41 - x) + ( - 7(y + x)$

for x=-2 and y=-4.

We substitute to get:

$5(41 - - 2) + ( - 7( - 4 + - 2)$

We now simplify to get:

$5(41 + 2) - 7( - 6)$

$5 \times 43 + 42$

$215 + 42 = 257$

Plz solve -8 ( x - 3 ) - 4x = 48

Llana [10]

Answer:

x = -2

Step-by-step explanation:

-8 ( x - 3 ) - 4x = 48

Distribute

-8x +24 -4x = 48

Combine like terms

-12x +24 = 48

Subtract 24 from each side

-12x+24-24 = 48-24

-12x = 24

Divide each side by -12

-12x/-12 = 24/-12

x = -2

AlexFokin [52]

Answer:

$x\approx7.8$

Step-by-step explanation:

In relation to the given angle, we are given the triangle's opposite side and hypotenuse. Therefore, we use the sine function to set up a proportion and solve for the opposite side:

$sin(\theta)=\frac{opposite}{hypotenuse}$
