Answer:
x + y = 5
3x + 3y = 15
Step-by-step explanation:
let x represent apple and y represent orange
Hence x + y = 5
and 3x + 3y = 15
Solving both equations simutaneously
From first equation, x = 5-y
Substitute x=5-y into the second equation
3(5-y)+3y = 15
y= 0
x = 5-0 = 5
Answer:
9
Step-by-step explanation:
If you want the number to be divisible by three make sure the sum of all the numbers are divisible by three. Add all the numbers you have to see what they make.
3+4+2+8+4=21
So we just need to find the greatest number we can add to that to have it remain divisible by three. A number divisible by three is 30, and we can add 9 to 21 to make 30. Of course, there are other numbers we could add, but nine is the largest one-digit number that would work. Other smaller numbers include 3 and 6.
3+4+2+8+4+9=30
Now we check to see if our number is divisible by three
342984÷3 = 114328
114328 is a whole number so we know it's divisible.
The cost to pay for the gas if this car made a trip of 866 miles cost is $53.31.
A car averages 32 mpg and gas costs $1.97 per gallon.
By unitary method for 866 miles, average would be,
= 866/32
= 27.0625 miles per gallon
and the cost to pay for the gas if this car made a trip of 866 miles would be,
= 27.0625 × $1.97
= $53.31
Therefore, the cost to pay for the gas if this car made a trip of 866 miles cost is $53.31.

Answer:
see below
Step-by-step explanation:
3(x + 4) + 2 = 2 + 5(x – 4)
Distribute using the distributive property
3x + 12 + 2 = 2 + 5x – 20
Combine like terms (simplify)
3x + 14 = 5x – 18
Subtract 3x from each side using the subtraction property of equality
14 = 2x – 18
Add 18 to each side using the addition property of equality
32 = 2x
Divide each side by 2 using the division property of equality
16 = x
