Answer: -3x-5
Step-by-step explanation:
The guy above did you dirty
1 gallon of milk costs 0.50 more than 5 times a gallon of water.
From that information milk is 5x +0.50 the cost of water.
The cost of milk is $3.75, so now we have:
3.75 = 5x + 0.50
Subtract 0.50 from each side:
3.25 = 5x
Divide both sides by 5:
X = 3.25 / 5
x = 0.65
The cost of water = $0.65
That is the combination of 10 over 3, which is calculated as the quotient of factorials:
n!/k!(n-k)!
where n = 10 and k = 3:
= 10!/3!(10 - 3)!
= 10!/3!*7!
= (10*9*8)/(3*2*1)
= 720/6
= 120
therefore there a re 120 possible different groups
Answer:
Answer:x=
−3z−1
0
Step-by-step explanation:x=
Step 1: Add -2x to both sides.
2x+3z+4+−2x=2x+3+−2x
3z+4=3
Step 2: Add -3z to both sides.
3z+4+−3z=3+−3z
4=−3z+3
Step 3: Add -4 to both sides.
4+−4=−3z+3+−4
0=−3z−1
Step 4: Divide both sides by 0.
0
0
=
−3z−1
