There are 178 more bikers than hikers if there are 676 people in the park total how many people are hikers?
Verizon [17]

Answer:

The total number of hikers are 427

Step-by-step explanation:

Let:

The number of bikers = x

The number of hikers = y

There are 178 more bikers than hikers

y = x + 178

if there are 676 people in the park total how many people are hikers?

Hence:

x + y = 676

we substitute x + 178 for y

x + x + 178 = 676

2x + 178 = 676

2x = 676 - 178

2x = 498

x = 498/2

x = 249

y =x + 178

y = 249 + 178

y = 427

Therefore:

The number of bikers = x = 249

The number of hikers = y = 427

The total number of hikers are 427

Pls help me with this
Taya2010 [7]

Answer: x=5 z=115

Step-by-step explanation:

First, subtract 91 from 180(which is the amount of degrees on the line)

Secondly, subtract 24 from 89(which is the amount of degrees on the x portion

Next, divide 65 (the amount of angles missing after subtracting 24)

Lastly, add 65(for the perpendicular value), then find the difference between 180 and 65 to get to the value of z.
