25/D
26/ C
Step-by-step explanation:
Conversion:
3 km - 3000m
0.5 km - 500 m
1.05 km - 1050 m
Solution:
3, 000 m = 500m + 1050m + n
3, 000 m = 1550m + n
n = 3, 000 m - 1550m
n = 1450m
1.45 kilometers must PJ hike to reach the river.
Answer:
Expand
2b + 3 = 2 -3b -9
Correct like terms
2b + 3 = 3b - 7
Move 2b to the otherside as a negative number and -7 to the otherside positive number.
-4 = -5b
Divide both sides by negative five
b is equal to 4/5
Step-by-step explanation:
<em>h</em><em>o</em><em>p</em><em>e</em><em> </em><em>i</em><em>t</em><em> </em><em>h</em><em>e</em><em>l</em><em>p</em><em>s</em><em> </em><em>y</em><em>o</em><em>u</em><em> </em><em>!</em><em>!</em>
In math, IS represents = OF represents multiply
1. So for the first problem is saying 24% * 80 24% is the same as .24 so .24*80=19.2
2. For this one the problem is saying 15=30%*x So for this we need to find x. So we divide both sides by .3 and get x = 50
3. You do the same thing as in 2. Im not gonna do all ur homework so you can do this one.
Hope that helps :)<span />
