<span>The missing value that represents the rate for Marie is 1/60. As mentioned in the table, rate (r) is the part (p) per minute (t). Let's check if it works for Lea. If p = 1/80t, then r = (1/80t)/t = 1/80 * t/t = 1/80 * 1 = 1/80. So, the formula works. Now, calculate the rate for Marie. If p = 1/60t, then r = (1/60t)/t = 1/60 * t/t = 1/60 * 1 = 1/60</span>
Do you still need the answer to this or nah?
Answer: x=3 and y=5
Step-by-step explanation: 11x-6y=3, 5x-8y=-25
11x-6y+6y=3+6y
11x/11=3/11+6y/11
x=3+6y/11
5(3+6y/11)-8y(11)/11
5(6y+3)-88y/11
30y+15-88y/11
88y-30y
58y
11(15-58y)/11=11(-25)
15-58y-15=-275-15
-58y/-58=-290/-58
y=5
x=3+6(5)/11
3+30
33
33/11
x=3
x=3, y=5
1/4 is the slope!
That equation is in slope intercept form aka y=mx+b. M is the slope, and b is the y intercept
In that equation, m=1/4 therefore 1/4 is the slope
Hope this helps!
Angle D is 60° because it is a supplementary angle, meaning 180 (straight line) - 120 (angle A) = 60°
