We can use the substitution method to solve this problem.
The second equation is
, so we can plug in 2x for 'y' in the first equation:
Multiply:
Combine like terms:
This is the x-value of our solution, we can plug this into any of the two equations to find the y-value:
Multiply:
This is the y-value of our solution. So our entire solution is (3, 6).
Answer:
I think 15.
Step-by-step explanation:
20 ÷ 5=4 and 5 × 3=15.
Convert liters to milliliters so that you have one unit for all of the amounts in the question.
1 liter is equal to 1000 milliliters, so multiply the 1.5 liters you have by 1000:
Since you drank 295 milliliters, and your friend drank 135 milliliters, you will subtract those values from the amount in the bottle:
There is
1070 milliliters of water left in the bottle. If you want to find the amount remaining in the bottle in liters, divide the amount remaining by 1000 to convert milliliters to liters:
Converted back into liters, there is
1.07 liters of water left in the bottle.
Answer:
96.90
Step-by-step explanation:
1700x.0570=96.90
Answer: UV = 52
Concept:
Additive property of length, or the segment addition postulate, states that given 2 points A and C, a third point B lies on the line segment AC if and only if the distances between the points satisfy the equation AB + BC = AC.
Solve:
<u>Given information</u>
TU = 4x
UV = 2x + 14
TV = 7x - 5
<u>Given expression deducted from the additive property of length</u>
TV = TU + UV
<u>Substitute values into the expression</u>
7x - 5 = 4x + 2x + 14
<u>Combine like terms</u>
7x - 5 = 6x + 14
<u />
<u>Subtract 6x on both sides</u>
7x - 5 - 6x = 6x + 14 - 6x
x - 5 = 14
<u>Add 5 on both sides</u>
x - 5 + 5 = 14 + 5
x = 19
<u>Find UV by substituting the value of x</u>
UV = 2x + 14 = 2 (19) + 14 =
