Answer:
75 green tiles
Step-by-step explanation:
Green : Blue = 3 : 4
3 : 4 = x : 100
Write as fractions
3/4 = x/100
Cross Multiply (numerator * denominator / numerator * denominator)
300 = 4x
Divide both sides of the equation by 4
x = 75

Answer:
Yes. Plug in your x and y into the first given equation and you'll see why.
(7) ≥ -(2)+1
7 ≥ -1 (7 is greater than or equal to -1)
...As well as the second equation.
(7) < 4(2)+2
7 < 8+2
7 < 10 (7 is less than 10)
Step-by-step explanation:
-5x+13y=-7
5x+4y=24
add the equation to eliminate x:
13y+4y=-7+24
17y=17
solve for y:
17/17y=17/17
y=1
then plug in y into any equation to solve for x:
-5x+13y=-7, y=1
-5x+(13*1)=-7
-5x+13-13=-7-13
-5x=-20
-5/-5x=-20/-5
x=4
the answers are x=4, y=1
