Answer:
line 1
Step-by-step explanation:
because
3x + 2y + z = 11 ➡ z = 11 - 3x - 2y
3x and 2y must change sign when transfer to other sid eof equation
Answer:
When ordering fractions, you don't only have to take in account for the numerator, you also have to take into account the denominator, whereas with whole numbers, you only have to take into account the numerator. Also, in a fraction, you have to make sure the denominators are the same before ordering them.
Answer:
12y and 6bc
Step-by-step explanation:
multiply by 2
45machines:20mins
20mins=1/3hour
45machines:1/3hour
times 3
135machins=1hour
135machines per hour
B. 30 in 15
15=1/4 hour
30=1/4hour
times 4
120machines per hour
both produce for 2 hours
A. is 135*number of hours, B is 120 times number of hours
135*2+120*2=
270+240=
510
make 510 machines in 2 hours
Answer:
Step-by-step explanation:
In order to solve this equation we should know the format of slope-intercept form, which is: 
Given you already have the y-intercept and slope for the line, it's a matter of plugging in the slope for the "m" variable slot and the y-intercept into the "b" variable slot.
This is turn gives us our equation:
