Answer:
a = 3
Step-by-step explanation:
Factorise both expressions\x² - x - 6 = (x - 3)(x + 2)
x² + 3x - 18 = (x - 3)(x + 6)
Thus both expressions have a common factor of (x - 3) , thus
a = 3
Answer:
<h2>x=5/7</h2><h2>y=12/7</h2>
Step-by-step explanation:
5x+2y=7
5x+2(x+1)=7
5x+2x+2=7
7x=5
x=5/7 or ~0.71
y=5/7+1
y=12/7 or ~1.71
<u>Check your solutions:</u>
1.71=0.71+1
1.71=1.71 ✅
5(0.71)+2(1.71)=7
3.55+3.42=6.97 ✅
we rounded down so this answer is fine
Answer:
B. 14 ft approx
Step-by-step explanation:
Given data
A teepee has a conical shape
Diameter= 10ft
radius= 5 ft
Volume = 366ft³
Height = ????
The expression for the volume is
V= 1/3πr^2 h
substitute
366= 1/3*3.142*5^2*h
366= 1/3*78.55*h
366= 26.18h
h= 366/26.18
h=13.98 ft
h= 14 ft approx
Hence the Height is 14 ft approx

<h3><u>Answer</u>:- </h3>
<h3><u>Solution:-</u></h3>
<u>Given </u><u>that </u><u>:</u><u>-</u>
- job last for h hours
- Cost of job lasting more than 1 hour = $30
- Cost for the first hour = $75
Remaining hours for which the job will last after first hour= (h-1)
<u>Therefore</u>,
Cost for subsequent hours = 30×(h-1)
= 30(h-1)
Total Cost for job = Cost for 1st hour + Cost for subsequent hours
