There are certain cases that need to be taken into consideration: 1. If the lines intersect at one point the solution that fits all equations is exactly that point. 2. If the lines do not intersect at only one point the system has no solution because the lines 3. If the system of equations intersects completely overlaps the other line we say that we have an infinite number of solutions that fits the equations.
Answer:
35%
Step-by-step explanation:
The percentage of blue tint in paint mixture (a mixture of 200ml of green tint, 350ml of blue tint and 450ml of red tint) is the ratio of the quantity of blue tint to the total quantity of tint.
The total quantity of tint
= 200ml + 350ml + 450ml
= 1000ml
The percentage of blue tint in the paint mixture
= 350ml/1000ml * 100%
= 35%
Find the perimeter of the yard ( the distance around the yard).
A rectangle has two sides of each dimension.
The perimeter is 20 + 20 + 45 + 45 = 130 feet.
Now multiply the total feet by the cost per foot:
130 feet x 25 per foot = $3,250 total.

Laura, David, and Carlos served a total of 115 orders
David served 3 times as many orders as Carlos. David = 3x
Laura served 10 more orders than Carlos. let Carlos = x
How many orders did they each serve? Laura = x + 10
Carlos + David + Laura = 115
x + 3x + x+10 = 115
5x + 10 = 115
5x = 115 - 10
5x = 105
x = 21 Carlos
63 Davide
31 Laura
add then up 115 Total
