Answer:

x= 6.85 or 89/13

Step-by-step explanation:

perimeter is sum of all sides added, so add them all and set them equal to 84

4(x-3) + 3x - 1 + 6x + 8 = 84

distribute

4x + 12 + 3x - 1 + 6x + 8 = 84

combine like terms

13x - 5 = 84

solve for x

x = 89/13 = 6.85

Find the measure of the exterior angle X:<br> 125
igomit [66]
Answer: x=80°

Explanation:
To find the exterior angle x we first need to find the last corner angle (a) of the triangle. The angles of triangles add up to 180° so we can use the formula: 25+55+a=180

Solving formula:
25+55+a=180
80+a=180
(Subtract 80 from both sides)
a=100°

Now that we know a=100 we can find the exterior angle. a+x=180 because the angles are on a straight line which equals 180°

a+x=180
100+x=180
(Subtract 100 from both sides)
x=80°

Hope this helps! Please leave a thanks if possible so I can continue to help others :)

Varvara68 [4.7K]

Answer:

150

Step-by-step explanation:

Given that;

Company A offers;

Salary= $ 17000

commission= $100 per tv set

Company B offers;

Salary= $29000

Commission = $ 20 per tv set

Let the number of tv set sold to be= x

To solve this problem, the amount obtained after selling for A option should be equal to B option

<u>Form equations</u>

<u>17000 +100 x = 29000 + 20x\\\\\\100x-20x= 29000-17000\\\\\\80x=12000\\\\\\x=12000/80 = 150</u>

The number of televisions sold for the options to be equal = 150

Flauer [41]

Answer:

running 1.5 hours

Walking 4.5 hours

Step-by-step explanation:

Let the amount of time she spends on walking be x

d/3 + d/9 = 6            Multiply by 9

3d + d = 6*9

4d = 54                     Divide by 4

4d/4 = 54/4            

d = 13 2/4 = 13 1/2 = 13.5 miles

d/3 = 13.5/3 = 4.5 hours

d/9 = 13.5/<u>9 = 1.5 hours</u>

Total                6 hours

I hope this is the right interpretation.
