Answer:
t=2Q-sr/r
Step-by-step explanation:
We are to make t the subject of formula from the given question
Q=r/2 (s+t)
Q=Sr+tr/2
Cross multiply
2Q=Sr+tr
2Q-sr=tr
t=2Q-sr/r
Answer:
Step-by-step explanation:
area = 30x + 30(x+3) + 30(2x)
= 30x + 30x+90 + 60x
= (120x + 90) m²
length of planting area = x + (x+3) + 2x = 4x+3 m
area = 30(4x+3) = (120x + 90) m²
x = 5
maple area = 30(5+3) = 240 m²
locust area = 30(2·5) = = 300 m²
Since 12 is 8 x 1 1/2 she needs 1 1/2 time as much fruit.
1 1/2 x 10 = 15 strawberries and 1 1/2 x 4 = 6 oranges.
You could also solve this using proportions:

Cross multiply and get 8n= 120 divide by 8 and get 15 strawberries
Do the same for the oranges:

You can see that 4/8 = 1/2 so n/12 has to be 6 to be 1/2 (or solve it using cross products like I did above).
