Answer:
-24
Step-by-step explanation:
you first do the parenthesis first then you do 3x4 12 then you add 9 and then -48 so your at negative 40 then you do 8+8 which is 16.
Round trip travel: 2*15miles*$0.45/mile = $13.5
Equipment: $84 + $15.50 + $47 + $32 + $22 = $200.50
Tax = $200.50 * 5%/100 = 10.025
Lessons: $25*10 = $250
Total cost = 13.5 + 200.5 + 10.025 + 250 = $474.025
We'll want to end this one with x ≥ another value.
So, subtract 5 from both sides.
x+5≥10
-5 -5
x≥5
So, x must be greater than or equal to 5.
Answer:
x = 7.535 and y = 0.307
Step-by-step explanation:
Given that,
Two equations,
2x + 3y = 8 ...(1)
x – 5y = 6....(2)
Multiply equation (2) by -2.
-2x + 10y = -12....(3)
Now, adding equations (1) and (2),
2x + 3y -2x + 10y = 8-12
13y = 4
y = 0.307
Put the value of y in equation (2).
x – 5(0.307) = 6
x = 6 + 1.535
x = 7.535
So, the solutions of the given equation are x = 7.535 and y = 0.307.
