Answer:
2.75x + 114 = 320.25
x = $75
Step-by-step explanation:
2.75x + 114 = 320.25
number of hours of labor (2.75) times the cost per hour of labor (x) + cost of parts (114) = total cost (320.25)
2.75x + 114 = 320.25
subtract 114 from both sides
2.75x = 206.25
divide both sides by 2.75
x = 75
------------------------
check the math:
2.75(75) = 114 = 206.25 + 114 = 320.25
7 is your number because 7x3=21 +5=26
There will be 110 mushrooms I think.
Year one: 10
Year two: 10 plus 10
Year three: 20 plus 20
Year four: 40 plus 30
Year five: 70 plus 40 which equals 110 mushrooms.
Answer:
B
Step-by-step explanation:
a,b and c are the sides of a triangle if it satisfies:
a<b+c , b<a+c and c<b+a
Here, a=4 and b=7
We have to find c
i.e. all those c which satisfies:
4<7+c , 7<4+c and c<4+7=11
A.3 it is not true since it doesn't satisfies second inequality
B.5 it is true
C.7 it is true
D.9 it is true
E.11 This is clearly false, since it doesn't satisfies inequality third
F.17 This is clearly false, since it doesn't satisfies inequality third
Hence, correct options are:
B.5
C.7
D.9

Answer:
x < -3 1/2 or 3.5
Step-by-step explanation:
-9x + 5 < 17
13x +25 < -1
If we add the 2 equations together, we will have
4x + 30 < 16
4x < 16 - 30
4x < -14
Divide both sides by 4
x< -14/4
x < -3 1/2 or 3.5
