Answer:
58 years old
Step-by-step explanation:
the equation would be 500-4x=268 with x being his age.
subtract both sides by 500 to get -4x=-232
then divide both sides by -4 to get x=58
The following do not have a solution:
• 6x+1=3(2x-4)
• -4(x+3)=4(-x-1)
Answer:
x = 12
Step-by-step explanation:
Angles in a triangle add up to equal 180 degrees
Hence, 10x - 11 + 3x - 2 + 3x + 1 = 180
( note that we just created an equation that we can use to solve for x )
we now solve for x using the equation we created
10x - 11 + 3x - 2 + 3x + 1 = 180
step 1 combine like terms
10 + 3x + 3x = 16x
- 11 - 2 + 1 = -12
we now have 180 = 16x - 12
step 2 add 12 to each side
- 12 + 12 cancels out
180 + 12 = 192
we now have 192 = 16x
step 3 divide each side by 16
16x / 16 = x
192 / 16 = 12
we're left with x = 12
Answer:

0 4
Step-by-step explanation:
This is a function table. For a linear function, find the average rate of change between the listed points called slope. Then use the slope to fill in other inputs and outputs for the function.
This means for every 3 units made in the input, the function moves down 1 output.
x y
15 -1
12 0
