-16 ( -2 +y) - 3y= -25
32 -16y -3y = -25
32 - 19y = -25
-32. -32
-19y =-57
y=3
AnsweTo see if multiple ratios are proportional, you could write them as fractions, reduce them, and compare them. If the reduced fractions are all the same, then you have proportional ratios.r:
Step-by-step explanation:
Equation 1 is ,
Equation 2 is [/tex] 3x-2y = -1 [/tex]
for first equation LCD= 3 *5 = 15 , So we multiply whole equation by 15
Now multiply second equation by -3 , to make the coefficient of y equal and opposite , so that we can apply the elimination method
Add both the equations
Divide both sides by 11
Plug in any one of the equation we get
3(3) -2y = -1
9 - 2y = -1
subtract 9 from both sides
-2y = -10
divide both sides by -2
y=5
So the solution is x= 3 , y= 5
Which means
a. The system is consistent and independent. TRUE
Answer:
24 F
Step-by-step explanation:
Temp increases by 4F per hour.
-8F - 6F = 12F / 3hours
To find the unit rate for 5 you would do price/amount
So 5.75/40=.14375 this rounds down to .14
Therefore the correct answer would be B
For 6 the unit rate is the same, meaning you would have to do price/amount, so 2.99/8=.37375 which rounds to .37
So the correct answer is B
