Let h equal the number of hours the electrician works.

We can write the equation like this:

90h + 60 = 600

Solve for h.

90h + 60 = 600

~Subtract 60 to both sides

90h + 60 - 60 = 600 - 60

~Simplify

90h = 540

~Divide 90 to both sides

90h/90 = 540/90

~Simplify

h = 6

Therefore, the electrician work for 6 hours.

The correct answer is Option 1.

Best of Luck!

Find the measure of an exterior angle of each regular polygon: 100-gon.

Gelneren [198K]

If this is a 100-gon, then not only does it have 100 sides, it also has 100 central angles. Each one measures 360/100 = 3.6. This is the vertex angle for each of those 100 triangles. 180 - 3.6 = 176.4, which has to be split equally between the 2 base angles. This puts each of those at 88.2. If you are looking for the exterior angle to each of those, it's the supplement of them. 180-88.2 = 91.8

Allison’s dog is 6 pounds more than 5 times the weight of Gail’s dog. What algebraic expression could you make to find (g) which

emmasim [6.3K]

Given that Allison’s dog is 6 pounds more than 5 times the weight of Gail’s dog, it is important to know the following:

1. The word "more" indicates an Addition.

2. The word "times" indicates Multiplication.

Knowing this, you can write the following expression to represent "5 times the weight of Gail’s dog", where "g" is the weight of Gail’s dog:

$5g$

Therefore, you can determine that the weight of Allison's dog (in pounds) is the sum of 6 pounds and 5 times the weight of Gail's dog (in pounds). Then, you can represent this with this algebraic expression:

$5g+6$

Hence, the answer is:

$5g+6$
