Area of triangle = I/2*b*h
96 = I/2*b*8
96 = 4b
24in = b
Therefore perimeter = 24*3
= 72in
Answer:
D: all real numbers
R: (5, ∞)
Step-by-step explanation:
D: you can plug in anything for x and it makes sense. You can raise 3 to any real power (2, 1/2, -10 etc) and get an answer.
R: Because 3^x only produces positive numbers, the range is (0+5, ∞) ---> (5, ∞).
Answer:
Step-by-step explanation:
192 * 20 = 3,840
A + b = 147....a = 147 - b
5.85a + 4.40b = 786
5.85(147 - b) + 4.40b = 786
859.95 - 5.85b + 4.40b = 786
-5.85b + 4.40b = 786 - 859.95
- 1.45b = -73.95
b = -73.95 / -1.45
b = 51 <== she used 51 lbs of type B coffee
Answer:
left side: 3x *- (-2x) =8+7 right side: 2v -10 = -3v *-5
Step-by-step explanation:
on the left side you add 2x to move it from the right to the left. on the right side you multiply negative with positive which is negative
