Answer:
164 is not a perfect square
Step-by-step explanation:
Because if you calculate its square root, 164 doesn't have a whole number as its square root and a perfect square needs the square root to be a whole number.
Answer:
B) 200 miles.
Step-by-step explanation:
Let M = miles that you need to drive
45 + 0.295M = 90 + 0.07M
90 - 45 = 0.295M - 0.07M
45 = 0.225M
M = 45/0.225
M = 200

I think buying two 10 inch pizzas would make more sense because you can get different topping on each. For example where I live a 10 inch pizza is 5 dollars and a 20 inch pizza is 18 dollars so 2 10 inch pizzas would cost less as well.
Hope this helps! :)
Answer: 139°
Reasoning:
Angle 3 and 5 are congruent, so you can put their expressions equal to each other and solve.
14x-1=9x+14
To isolate the x to one side, subtract the 9x from the 14x.
5x-1=14
Now to get the constants on one side, add the 1 to the 14.
5x=15
Now divide both sides by 5 to isolate the x.
5x/5=15/5
x=3
Now that we know that, we can figure out angle 3.
9(3)+14
27+14= 41
Angle 3 = 41°
Now that we know what angle 3 is, we can subtract it from 180° to figure out angle 8 since angle 3 and 8 are supplemtary angles, aka linear pairs.
180°- 41°= 139°
<h3>Double checking your answer:</h3>
41°+139°=180°
