Step-by-step explanation:
B= -20+45/56
B=-20.80
The only error you made is on problem 3. Everything else is correct. Nice work.
-------------------------------------------------------
Here is how to solve problem 3
Plug x = 1 into the equation and solve for y
-3x + y = 1
-3*1 + y = 1 ... replace x with 1
-3 + y = 1
y - 3 = 1
y - 3 + 3 = 1 + 3 .... add 3 to both sides
y = 4
<h3>The answer is 4</h3>
-------------------------------------------------------
Verifying the answer:
Plug (x,y) = (1,4) into the equation. Both sides should be the same number after simplifying both sides.
-3x + y = 1
-3*1 + 4 = 1 ..... replace x with 1; replace y with 4
-3 + 4 = 1
1 = 1
The answer is confirmed.
If you were to graph -3x + y = 1, which is equivalent to y = 3x+1, you'll find that the point (1,4) is on this line.
Answer:
The answer would be 2:30
Step-by-step explanation: lets say they both take 3 hours, that would mean that if they work together, that means they can cut their time by half,
but if jai is slower paced it and takes about 1 hour more, just add 1 hour to the hour and 30 to be able to get 2:30
pls give brainliest.
Answer:
-28
Step-by-step explanation:
If y = 98 when x is 14, y is always seven times x. We know this because x = y/7.
So if Y is seven times bigger, -4 * 7 = -28
