Answer:
we just did this in class a few weeks ago in pretty sure its 3 because that's where the line crosses the y axis but im not 100 percent sure good luck!❤
Answer: the rate uphill is 6 mph.
The rate downhill is 10 mph
Step-by-step explanation:
Let x represent the rate at which the jogger ran uphill.
The jogger runs 4 miles per hour faster downhill than uphill. This means that speed at which the jogger ran downhill is (x + 4) mph
Time = distance/speed
if the jogger can runs 5 miles downhill, then the time taken to run downhill is
5/(x + 4)
At the same time, the jogger runs 3 miles uphill. It means that the time taken to run uphill is
3/x
Since the time is the same, it means that
5/(x + 4) = 3/x
Cross multiplying, it becomes
5 × x = 3(x + 4)
5x = 3x + 12
5x - 3x = 12
2x = 12
x = 12/2
x = 6
The rate downhill is 6 + 4 = 10 mph
Supplementary=add to 180. U/V=7/13, U+V=180. Solving, U=63 and V=117
Answer:
C. 15 cm
Explanation:
The radius is the same in a circle. PA and PB has same length of 8 cm.
In order to find AC, find the length of PA and PC.
Here given:
- PC = PB + BC = 8 cm + 9 cm = 17 cm
Hence solve using Pythagoras theorem:
Answer:
14
Step-by-step explanation:
PEMDA ( ( ), ^, x, ÷, +, -)
write equation
(2x4) + (12x2) ÷ 4 =?
solve
(2x4) = 8
rewrite
8 + (12x2) ÷ 4
solve
(12x2) =24
rewrite
8 + 24 ÷ 4
solve
24 ÷ 4 = 6
rewrite
8 + 6
Solve
8+6=14
Answer = 14
