Answer:
as a decimal it is 0.4 as a fraction it is 2/5
Answer:
Equation Form:
x=7,y=−2
Step-by-step explanation:
Multiply each equation by the value that makes the coefficients of x
opposite.
(−1)⋅(2x+5y)=(−1)(4)
2x−2y=18
Simplify.
−2x−5y=−4
2x−2y=18
Add the two equations together to eliminate x
from the system.
(−2x−5y=−4) +(2x−2y=18) = (-7y=14)
Divide each term by −7 and simplify.
y=−2
Substitute the value found for y into one of the original equations, then solve for x.
x=7
The solution to the independent system of equations can be represented as a point. (7,−2)
The result can be shown in multiple forms.
Point Form:
(7,−2)
Equation Form:
x=7,y=−2
I'm not sure if this is correct but you would put it into an equation while you solve for X. so 0.75x=150 or equivalently would be like (3/4)x=150 Then after that you would divide both sides by 0.75 or 3/4
Answer:
a) C(x) = 4x + 350
b) 13x; $13
c) 39
Step-by-step explanation:
a) Initial cost of lawnmower = $350
Maintenance cost for 1 lawn = $4
Maintenance cost for x lawns = 4x
Total cost function, C(x) = 4x + 350
b) Revenue = Cost + Profit
= C(x) + P(x)
= 4x + 350 + 9x - 350
= 13x
Charge per lawn = 
= 
c) For Jimmy to make a profit, P(x) must be greater than zero i.e.
The smallest integer value of x that satisfies this inequality is 39. Therefore, Jimmy needs to mow 39 lawns in order to start making profit.
