Mark bikes 4/10 of a mile in 1/5 of an hour.
That is 4/10miles in 1/5hours
Average speed = Distance ÷ time
= 4/10 ÷ 1/5 = 4/10 ×5/1 = 2 miles/hour
Split it into three rectangles, find the area of each one and add them together. You can split it multiple ways but the way I did it, you would end up with this: 10*2+2*2+2*2
Answer:
c
Step-by-step explanation:
Let 1/x = a &
1/y = b
So, now the equation:
2a +3b = 13 --------------------(i)
5a - 4b = -2 --------------------(ii)
To eliminate a, Multiply equation (i) by 5 and multiply (ii) by (-2)
(i)*5 10a + 15b = 65
(ii)*(-2) <u> - 10a + 8b = 4</u> ( Now add, a will be eliminated}
23b = 69
b= 69/23
b = 3
Plug in the value of b in equation (i)
2a + 3*3 = 13
2a + 9 = 13
2a = 13 - 9
2a = 4
a= 4/2
a = 2
Now a = 1/x ------>x = 1/a = 1/2
b = 1/y ----------->y = 1/b = 1/3
Answer:
40°, 60°, and 80°
Step-by-step explanation:
We know that the sum of the angles of a triangle is equal to 180°.
We can use this equation to solve for these angles:
180 = 2x + 3x + 4x
180 = 9x
20 = x
Then substitute the solution in for x to solve for the angles:
2(20) = 40°
3(20) = 60°
4(20) = 80°
Therefore, the angles are 40°, 60°, and 80°.
It would be lets see 3.25 is the number so 185is divied by 50 miles
