360 - 2(65) = 230
A = C = 230/2 = 115
m<y = 360 - 115 = 245
answer: m<y = 245
The answer is 166cm
Explanation: 2LH+2WH+2LW
Answer:
45; 9
Step-by-step explanation:
1) if the rate of the boat in still water is 'b' and the rate of the current is 'c', then it is possible to write the rate of the boat going upstream: b-c, downstream: b+c.
2) the basic formula is: D=r*t, where D - distance, r - rate/velocity, t - time;
3) according to the condition it takes 3 hours to travel 108 km upstream, it means according to the formula above 3(b-c)=108;
4) according to the condition it takes 2 hours to travel 108 km downstream, it means according to the formula above 2(b+c)=108;
5) if to make up the system of two equations, then:

6) rate of the boat in still water: 45 km/h;
rate of the current: 9 km/h.
Answer: The slope is 2.
Step-by-step explanation:
First rewrite the equation in slope intercept form to find the slope.
4x -2y = 8
-4x -4x
-2y = 8 - 4x Divide both both sides by -2 to solve for y
y = -4 + 2x rewrite it in slope intercept form.
y= 2x -4 the slope as you can see now is 2.
d = (t + r) / 2
Multiply each side by 2 :
2d = t + r
Subtract r from each side :
2d - r = t
