Hey there! :D

So, the steps should look somewhat like this: 

5x+5=-10

5x+5(-5)=-10(-5)

5x= -15

5x÷5= -15÷5

x=-3

I hope this helps!

1. Subtract 5 from both sides

5x=10-5

2. Simplify 10-5=5

So 5x=5

3. Divide both sides by 5

X=1

If a and b are the measures of two first quadrant angles and sin a = 4/9 and sin b = 2/5 find sin(a+b).
frutty [35]

Answer:

sin(a+b)=\frac{4\sqrt{21}+2\sqrt{65}}{45}

Step-by-step explanation:

we are given

sin(a)=\frac{4}{9}

sin(b)=\frac{2}{5}

Firstly, we will draw triangle

we get

cos(a)=\frac{\sqrt{65} }{9}

cos(b)=\frac{\sqrt{21} }{5}

now, we can sue formula

sin(a+b)=sin(a)cos(b)+cos(a)sin(b)

now, we can plug values

sin(a+b)=\frac{4}{9}\times \frac{\sqrt{21} }{5}+\frac{\sqrt{65} }{9}\times \frac{2}{5}

now, we can simplify it

sin(a+b)=\frac{4\sqrt{21}+2\sqrt{65}}{45}

Find the measure of angle A
omeli [17]

Answer:

Step-by-step explanation:

A and B are along a straight line

An electrician charges an hourly rate of $60, but also charges a fixed fee for making house calls regardless of time spend on th
Luba_88 [7]

Answer:

$50

Step-by-step explanation:

Step one:

charges per hour= $60

We are told that the electrician earned $350

for a job that took 5hours

The linear equation to represent his earnings is

let the flat fee be x

C=60t+x------------1

so for C=$350

Required

the flat fee

350=60(5)+x

350=300+x

collect like terms

x=350-300

x=50

Flat fee is $50

3x<br> Are 10 - 20 and 5(2 - 20) equivalent expressions? Explain.
Nutka1998 [239]

Answer:

No.

Step-by-step explanation:

Take the second expression: 5(2 - 20)

To solve, you must distribute the 5 to all terms within the parenthesis:

5(2 - 20) = (5 * 2) - (5 * 20) = 10 - 100 = -90

On the other hand:

10 - 20 = -30

∴ the two expressions are not equivalent.
