Answer:
1.627 miles
Step-by-step explanation:
Longest distance: 2.55 miles
Shortest distance: 0.923 miles
difference: 2.55 miles - 0.923 miles = 1.627 miles
Answer:
x = 200
y = 100
Step-by-step explanation:
20x + 30y = 7000 Divide by 10
15x + 35y = 6500 Divide by 5
===============
It helps if you break down both equations to something simpler. It looks like not always.
(2x + 3y = 700) Multiply by 3
(3x + 7y = 1300) Multiply by 2
==================
6x + 9y = 2100
<u>6x + 14y =2600</u> Subtract
-5y = - 500 Divide by -5
-5y/-5 = -500/-5
y = 100
2x + 3y = 700 substitute y = 100
2x+ 3*100 = 700 Combine
2x + 300 = 700 Subtract 300 from both sides.
2x = 700 - 300
2x = 400
x = 400/2
x = 200
===================
Hockey check
15x + 35y = 6500
15*200 + 35*100 = 6500
3000 + 3500 = 6500 Just as it should.
X=45
Why?
Becuz this triangle relies on 180 degrees. So 180-170= 10
10+125=135
180-135=45
Answer:
h = 2f + 30 (in inches)
Step-by-step explanation:
The length of the femur bone is f. Hence twice the length of femur bone is 2f. since height of skeleton is 30 inches taller than 2f,
<u>h = 2f + 30</u>, assuming h is measured in inches
