Answer:
b is increased by 17% : A and E
b is decreased by 17%: H and J
Step-by-step explanation: Took the test hope this helps
You can write these scenarios into equations:
y = distance (in miles)
x = the number of hours [you could put h instead of x, doesn't matter the variable]
Nolan
2x + 4 = y [rides 2 miles per hour(x), and had already gone 4 miles/is 4 miles in]
Hugo
3x = y [rides 3 miles per hour(x), and just started riding]
You can set these two equations equal to each other to find out when they meet: [this will first find how long it will take for them to meet]
2x + 4 = 3x You need to isolate/get x by itself, subtract 2x on both sides
2x - 2x + 4 = 3x - 2x
4 = x Now that you found x, you can use this to find y, you can use either equation to plug in 4 for x
3x = y
3(4) = y
12 = y
2x + 4 = y
2(4) + 4 = y
12 = y
x = 4 hours
y = 12 miles
Answer:
a=29
Step-by-step explanation:
If a=b and b is 25
Then a is 25
25+24=49
