Answer:
2.5 miles
Step-by-step explanation:
22.50-6=16.50
16.50÷3=5.5
5x + 4y = 8
-5x + 3y = -1
Let's add both equations, to eliminate x.
5x + 4y - 5x + 3y = 8 - 1
7y = 7
y = 1
Let us substitute this value of y in equation 1, so we can find x.
5x + 4 = 8
5x = 4
x = 4/5
Day One- 2d (d being Day Two)
Day Two- d
Day Three- 5 miles
So the expression would be:
5 + 2d + d
Now, we add together the like terms.
5 + 3d
Hope this helps!
Answer:
a
Step-by-step explanation:
2x +7= 19
2x= 19 -7 <em>(-7 on both sides)</em>
2x= 12 <em>(</em><em>simplify</em><em>)</em>
x= 12 ÷2
x= 6
