Answer:
x= 4
y= -5
Step-by-step explanation:
-2x+6y=-38 equation 1
3x-4y=32 equation 2
using equation 1 we have:
-2x+6y=-38
6y +38 = 2x
3y + 19 = x equation 3
using equation 3 in equation 2 we have:
3(3y + 19) - 4y = 32
9y + 57 -4y =32
5y = 32 -57
5y = -25
y= -25/5
y = -5
so we have:
3y + 19 = x
3(-5) +19 = x
x= 4
The set of x ordinates or {1,2,3}
Answer:
t = 0.7
Step-by-step explanation:
s = k/t where 'k' is the constant of variation
given: 0.5 = k/7 so k = 3.5
5 = 3.5/t
5t = 3.5
t = 0.7
Answer:
160 mL of fruit juice and 400 mL of sparkling water
Step-by-step explanation:
According to the statement we have that the ratio between fruit juice and sparkling water is 2/5.
Therefore, we could also say that:
200/500
with it could be done with 200 mL of fruit juice and 500 mL of sparkling water, so for 400 mL, how much would it be:
400 * 200/500 = 160
Therefore, the largest amount of the drink can be made with 160 mL of fruit juice and 400 mL of sparkling water.
