Answer:
<A =21
<B = 84
<c = 75
Step-by-step explanation:
<A =x
<B = 4x
<C =5x-30
The sum of A+B+C = 180
x+ 4x + 5x-30 = 180
Combine like terms
10x -30 = 180
Add 30 to each side
10x-30+30 = 180+30
10x = 210
Divide by 10
10x/10 = 210/10
x= 21
Since x =21 we can find the value of the angles
Substituting x into the equations for angles A, B and C
<A =21
<B = 4x = 4*21 = 84
<C = 5x-30 = 5*21-30 = 105-30 = 75
Hi there!
You're answer is going to be- 2.8 lbs.
Hope this helps!
The answer is D
To solve the inequality:
3-2x >= -17
-2x >= -20
x <= 10 when you divide by a negative, the inequality sign switches
Graph D covers all numbers less than or equal to 10
Answer:
millimeters.
Step-by-step explanation:
We have been given that a leak in a water tank causes the water level to decrease by millimeters each second.
To find the decrease in water level in 5 hours let us multiply water decrease in one second by number of seconds in 5 hours.
Using the exponent product rule let us add the exponents with same base (10).
Therefore, the water level in tank decreased millimeters in 5 hours.
