Answer:
Step-by-step explanation:
We have been given a parallelogram. We are asked to solve for the values of x and y.
We know that opposite sides of parallelogram are equal, so we can set equation as:
Similarly, we will solve for y.
To solve for z, we will subtract y from x as:
Therefore, the value of z is negative 3.
Answer:
Milk consumed in 30 days = (30 days)(3.25 litres/day) = 97.5 litres
Step-by-step explanation:
You are given a rate at which the milk is consumed (3.25 litres per 1 day). This is just multiplied by the 30 days to get your answer.
Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h
Step-by-step explanation:
Lets assume Malcolm maximum speed to be M km/h and Ravi maximum speed to be R km/h
Average of their maximum speed is; (M+R)/2 =260 km/h
This can be simplified to M+R= 260*2
M+R = 520.......................................(I)
When Malcolm's speed is doubled,
2M=R+80 km/h ----------------------(ii)
The two equations are;
M+R = 520 ------ M=520-R ----(i)
2M=R+80 ---------------------------(ii)
Replacing M with (i) above
2M=R+80
2(520-R) =R+80
1040 -2R =R+80
1040-80 = R+2R
960 = 3R
960/3 =R
320 =R
M+R =520
M=520-320 =200
Malcolm maximum speed is 200 km/h and Ravi maximum speed is 320 km/h
