Answer:
x < −4
Step-by-step explanation:
−3x + 5 > 17
Subtract 5 from both sides.
−3x > 17 − 5
Subtract 5 from 17 to get 12.
−3x > 12
Divide both sides by −3. Since −3 is < 0, the inequality direction is changed.
Divide 12 by −3 to get −4.
So then you get x < −4 which is your answer.
First you take the 20 hours it took for the 3 service calls... 20/3=6.67. Then you multiply 6.67X7.5=50.025 hours.
For this case we will define the following:
A, B: are the values of the triangle angles
a, b: are the values of the lengths of the sides opposite the angles A, B.
We then have to use the law of the sine:
Clearing the angle B we have:
Substituting values we have:
Answer:
the following is true:
A. angle B=38.08 degrees
Half of what the recipe required because your using half the required amount of sugar
Answer:
50.5 degrees
Step-by-step explanation:
Since this is a parallelogram then...
Angle U + Angle R = 180
3x+4+9x-10=180
Combine like terms
12x-6=180
Add 6 to both sides
12x=186
Divide both sides by 12
x=15.5
Now we plug 15.5 in for x to find Angle U
3(15.5)4=46.5+4=50.5
Angle U = 50.5 degrees
