Cancel something
we cancel x's
multiply 1st equation by 5 and 2nd by 7 and add them
-35x-30y=-5
<u>35x-28y=7 +</u>
0x-58y=2
-58y=2
divide both sides by -58
y=-1/29
sub back
5x-4(-1/29)=1
5x+4/29=1
minus 4/29 from both sides
note, 1=29/29
5x=25/29
divide bot sides by 5 (or times 1/5)
x=5/29
(5/29,-1/29)
Answer:
x = 1.9
Step-by-step explanation:
Thanks to a theorem we can use this proportion
10.47 : 4.44 = 4.44 = x
x = (4.44^2)/10.47 = 1,882865 = 1.9
8x10=80
8-are 8, 16, 24, 32, 40, 48, 56, 64, 72, 80
10-10, 20, 30, 40, 50, 60, 70, 80, 90, 100
Answer:
Yes, she would reach her goal of 10 miles. She would have ran 10.5 (or 10 1/2) miles.
Step-by-step explanation:
If you multiply 1 3/4 (7/4) times 6 (6/1) you would get 10 1/2, which in decimal form is 10.5.
Hope this helps!
