B
Step-by-step explanation:
Answer:
x = 7
y = 0
Step-by-step explanation:
→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:
4x + 9y = 28
-4x - y = -28
__________
8y = 0
y = 0
<u>→Plug in 0 for y, into an equation:</u>
-4x - 0 = -28
-4x = -28
x = 7
Answer:
- Architect - $83000
- Lawyer - $128000
Step-by-step explanation:
- Salary of a lawyer = l
- Salary of an architect = a
<u>According to the question we have:</u>
- l = 2a - 38000
- l + a = 211000
<u>Substitute l into the second equation and solve for a:</u>
- 2a - 38000 + a = 211000
- 3a = 211000 + 38000
- 3a = 249000
- a = 249000/3
- a = 83000
<u>Find the value of l:</u>
- l = 211000 - 83000
- l = 128000
Answer:
15.62 feet
Step-by-step explanation:
If the flagpole is 10ft tall and the shadow is 12ft long, and you need to find the distance from the top of the flagpole to the far end of the shadow, to get your answer, you must use the pythagorean theorum.
let height of flagpole = a
let length of shadow = b
let distance between the two = c
Answer:
x = 60
Step-by-step explanation:
The formula for this kind of question is
Area of sector = x / 360 * pi * r^2 = 24*pi
x/360 * pi * 12^2 = 24 pi
x/360 * pi * 144 = 24 pi the pi s cancel out
x / 360 = 24/144 Multiply both sides by 360
x = 24 * 360/144
x = 60
