Answer:
6000
Step-by-step explanation:
first you do 40000-28000 =12000 that means we have 12000 left
12000÷2 because the shirt equals 2 to give 6000
Since vertical angles are congruent, (4x+7)=5(x-4). So simplifying we get 4x+7=5x-20. If we add 20 on both sides we get 4x+27=5x. Now when we subtract x from both sides, we get x=27
Answer:
line
Step-by-step explanation:
y= 2+(x-1)*1= x+1
y=x+1
linear function, the graph is going to be a line
Answer:
4 2/3
Step-by-step explanation:
4(2x -3) + 8(x - 4) = 2(2x + 6)
Distribute
8x -12 + 8x -32 = 4x +12
Combine like terms
16x - 44 = 4x+12
Subtract 4x from each side
16x-4x-44 =4x-4x+12
12x-44 = 12
Add 44 to each side
12x-44+44 = 12+44
12x = 56
Divide each side by 12
12x/12 = 56/12
x = 14 / 3
Changing to a mixed number
x = 4 2/3
10 - 4 2/3
First, we convert mixed fraction into improper fraction.
4 2/3 = ((4*3)+2)/3 = 14/3
In subtracting fractions:
1) Both must have the same denominator.
10 is 10/1 and 14/3 have different denominators.
2) Once they have the same denominator, then subtraction may be performed.
10 - 14/3 = 10 * 3/3 - 14/3 = 30/3 - 14/3 = 16/3
3) 16/3 must be simplified.
16/3 = 5 1/3
10 - 4 2/3 = 5 1/3
