Answer:
112
Step-by-step explanation:
Since 7 goes into 7 put it down and subtract it’s 0
drop down 8 and only 7 goes into it (now you have 11 at the moment)
you have 1 remaining, drop down the 9, 7 goes in 15 twice, (so it’s 112)
with remainder of 5
Answer:
Step-by-step explanation:
I'll be solving this system of equations using the elimination method since the x and y values are neatly lined up.
I want to get a pair of x's or y's that cancel out, and it looks like the easiest way to start would be by multiplying the first equation by -2 (the y's will cancel).
I chose to multiply the first equation by -2 instead of multiplying the second equation by 5 because -2 is a smaller number and easier to multiply by.
Distribute -2 inside the parentheses. Now you've got:
Add up the equations from top to bottom.
-10x plus x is -9x, the -4y and 4y cancel out, and 16 plus 2 is 18. Make this one single equation.
Divide both sides by -9.
Substitute this value of x into the second equation (less to do with the x since it has no coefficient which means no multiplying).
Add 2 to both sides.
Divide both sides by 4.
The final answer is .
You need to rewrite the given equations in standard form y = mx +b, where m is the slope.
First equation:
x + 2y = 0
Subtract x from each side:
2y = -x + 0
Divide both sides by 2:
y = -x/2 +0 = y = -1/2x +0
This give you a negative 1/2 slope
The first equation is the correct one.
