Answer:

x=1

Step-by-step explanation:

Original Equation:

-5(5x+3)-5x+1= -44

Distribute the -5

-25x-15-5x+1= -44

Add like terms

-30x-14=-44

Add 14 to both sides

-30x=-30

Divide both sides by -30

x=1

Answer:

x = 1

Step-by-step explanation:

-5(5x+3) - 5x + 1 = -44

(-5*5x -5*3) - 5x + 1 = -44

(-25x - 15) - 5x + 1 = -44

-25x - 5x - 15 + 1 = -44

-30x - 14 = -44

-30x = -44 + 14

-30x = -30

x = -30/-30

x = 1

Check:

-5(/5*1) + 3) - 5*1 + 1 = -44

-5(5+3) - 5 + 1 = -44

-5*8 - 5 + 1 = -44

-40 - 5 + 1 = -44

-45 + 1 = -44

-4.5x-2y=-12.5 3.25x-y=-0.75<br> solve by elimination
creativ13 [48]
-4.5x-2y=-12.5 and 3.25x-y=-0.75
we first multiply the second equation by -2
(-2)*(3.25x-y=-0.75)=-6.5x+2y=-1.5
add the equation to eliminate the y
so yo get (-4.5x-6.5x)=(-12.5-1.5)
-11x=-11
x=1
now we plug in x into any equation to solve for y
-45x-2y=-12.5 and x=1
(-45*1)-2y=-12.5
-4.5-2y=-12.5
-2y=-12.5+4.5
-2y=-8
y=4
then your answer is x=1 and y=4

The specifications for an electronic device state that it is to be operated in a room with relative humidity ℎ defined by |ℎ − 5
Nadya [2.5K]

Answer: \Large\boxed{20 < h < 80}

Step-by-step explanation:

<u>Given inequality </u>

|h-50| < 30

<u>The goal of the question</u>

To find the minimum and maximum of the relative humidities

For this question, we need to solve the inequality

<u>Simplify the absolute value sign</u>

h-50 < 30          or          h-50 > -30

<u>Add 50 on both sides</u>

h-50+50 < 30+50          or          h-50+50 > -30+50

       \Large\boxed{h < 80}                   or                    \Large\boxed{h > 20}

Hope this helps!! :)

If tan∅ = √15÷10, find cot∅
Ghella [55]

Answer:

cot(∅) = \frac{10\sqrt{15} }{15}

Step-by-step explanation:

tan ∅ and cot ∅ are inverse functions

therefore the inverse of

tan ∅ = √15 / 10

is equal to

cot ∅ = 10 / √15

Rationalizing the denominator

\frac{10}{\sqrt{15} } * \frac{\sqrt{15} }{\sqrt{15} }

cot ∅ = \frac{10\sqrt{15} }{15}
