Answer:
<h2> <em><u>x = 2.82 (approx.)</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
- 356 = -77 - 99x
=> -77 - 99x = -356
=> -99x = -356 + 77
=> -99x = -279

=> x = 2.8181....
=> <em><u>x = 2.82 (approx.) (Ans)</u></em>
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:
-(5x+8)(x - 3)
Step-by-step explanation:
add and subtract second term to expression and factor using grouping
The perimeter of a rectangle that is 70 can be put into an equation like this:
2l + 2w = 70
The information given for us is this:
length = x
width = x - 9
Plug in the values for length and width:
2(x) + 2(x - 9) = 70
Multiply through the parenthesis:
2x + 2x - 18 = 70
Combine like terms:
4x = 88
Divide by 4 on both sides:
x = 22
The length of the rectangle is 22.
