Answer:
substitution method is tricky until u get the hang of it. 6y=x so 3x-8y=-50 can be rewritten as 3(6y)-8y=-50.
Step-by-step explanation:
3x-8y=-50.........(1)
6y= x ..............(2)
<u>Substituting x = 6y in (1)</u>
3(6y) - 8y = -50
<u>multiply 3(6y)</u>
18y - 8y = -50
<u>subtract 8y from 18y</u>
10y = -50
<u>divide to get y alone</u>
y = -50/10
y = -5
<u>now substitute. you know what y is. 6y=x / 6(-5)=x</u>
<u>solve :)
</u>
6y = x
6(-5) = x
-30 = x
x = -30
Answer: 80 miles
Step-by-step explanation:
- 400/5 = 80
- so 80 is 1/5 of 400
hope this helps :)
B. (3,-1) is the answer.
it is in the shaded part so it’s a solution
The simple answer is 3/3 in a total minus 2/3 being 1/3 is debit 1/3 of 600 is 200 so put 200 I. Those forms or 1/3
