Answer:
(-8,-6)
Step-by-step explanation:
You add the equations together, the 2y and -2y cancel out. You isolate x, then plug the answer you get for x from that into one of the equations. The amount you get for y is the y-coordinate and the amount you had for x is the x-coordinate. To check, try putting the y value into the equation you didn't plug the x into before. If you get the same x value as you had before, it means it's correct, I think.
Answer:
6.5 weeks.
55+50=105
35+60=95
It gets too wide when we double again.
55+ 100 =155
35+150=185
Therefore 55+70 =125
35+105= 125 Still too wide.
55+60=115
35+90= 125
The answer is between 6+ 7 weeks.
We then look at days.
Divide 55 weeks into 6.5 weeks less one day. Then apply 6.5
8.5 x 6.5 = 55 but when we plus 8.5+6.5=15
Divide 35 weeks into 6.5 weeks no remainder
5.5 x 6.5 = 35.75 =12
We see the ratio is 4:5
Banks round down and up for .5 answers.
Therefore both decimals round up so the answer is 6.5 weeks.
Step-by-step explanation:
Answer: You have to use the distributive property of multiplication. You're answer would be 21x+6y.
Step-by-step explanation: 3(7x+2y) You have to take each individual number in the parentheses by three. That will get you 21x+6y.
I think the answer would be d
