Answer:
There were 49 questions on this Geometry test.
Step-by-step explanation:
You can start by setting up a proportion:
x = total number of questions on Geometry test
= 
Now, to solve for x, cross multiply:
75.51x = 3700
Finally, isolate x and solve:
x = 49.0001324328
This is very close to 49.
4 p.m to 8 p.m is 4 hrs.....so she worked 4 regular hrs
8 p.m. to 1 a.m is 5 hrs...she she worked 5 hrs for 1.5 times as much
4x + 5(1.5x) = 92
4x + 7.5x = 92
11.5x = 92
x = 92 / 11.5
x = 8 <==== so she charged $ 8 per hr from 4 pm. to 8 pm. and (8 * 1.5) = $ 12 per hr for hrs after 8 p.m
Answer:
x=5
Step-by-step explanation:
First you have to solve for y. Since it is a isoceles triangle, the two base angles are equal. You dont even need to solve for y because both of them will equal 73. Now you know two of the angles are 73 degrees, 146 in total. Since you know the total degrees in a triangle is 180, set up an equation that is adding all the angles to equal 180. Then solve for x.
Solve:
73+73+(6x+4)=180
146+6x+4=180
150+6x=180
6x=30
x=5
