Answer:
y= 34/23
x= 123/46
Step-by-step explanation:
Solve for x
8x-5y= 14
x= 14/8 +5/8y
Sub x into second equation
– 5х+бу = -3
-5(14/8 +5/8y) + 6y= -3
-29/4 +23/8y = -3
y= 34/23
Sub y into any equation and solve for x
8x=483/23
x= 123/46
Answer:
1/8
Step-by-step explanation:
1st day......1/3
2nd day....1/6
3rd day....3/8
common denominator of 24
1/3 + 1/6 + 3/8 = 8/24 + 4/24 + 9/24 = 21/24 (this is water used)
that means that : (24/24 - 21/24) = 3/24 reduces to 1/8 .....water in the tank
Answer:
1
Step-by-step explanation:
Distance between x's (Δx)
0
This field is calculated automatically, you cannot change it's value manually.
Distance between y's (Δy)
1
d = √(Δy2 + Δx2) = √(12 + 02) = √1 = 1
It costs $122.4 dollars before the increase.

How to calculate percentage of a number. Use the percentage formula: P% * X = Y</h3>
- Convert the problem to an equation using the percentage formula: P% * X = Y.
- P is 17%, X is 7.20, so the equation is 17% * 7.20 = Y.
- Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Therefore, It costs $122.4 dollars before the increase.
