Answer:
3 laps.
Step-by-step explanation:
Hi! I can see how this is tricky, but I was a bit confused by the 4 in "If she runs 4." It says in the problem that the track is a mile long... So if you run the track 3 times, 3 x 1 = 3.
So basically, these questions want you to find the variable<em> x</em>, which you can do by isolating the variable.
3) x * 1/2 = 1/3 <-- To isolate the x in this case, you want to divide both sides by 1/2, aka multiply by 2.
x = 2/3
4) x * 3 = 2 <-- To isolate x, you want to divide both sides by 3
x = 2/3
5) 1/4 * x = 1/6 <-- To isolate x, you want to divide both sides by 1/4, aka multiply by 4.
x = 4/6 = 2/3
6) 4 1/2 * x = 1 1/2 <-- First, let's make these into improper fractions
9/2 * x = 3/2 <-- To isolate x, you want to divide both sides by 9/2, or multiply both sides by 2/9
x = 6/18 = 2/3
Answer:
-13.4+2.3c
Step-by-step explanation:
Add the like terms.
-6.5-5.1-1.8=-13.4
-13.4+2.3c
Hope this helps!
If not, I am sorry.
