S + l. = 34
11s + 21l= 514
-11s - 11l= -374
11s + 21l = 514
10l = 140
l = 20 long sleeve shirts
s + 20 = 34
s = 14 short sleet shirts
Answer:
area = 160 cm²
Step-by-step explanation:
area = (8x 4 x 4) + (4 x 4 x 2) = 160 cm²

Answer:
3.5
Step-by-step explanation:
To find the constant of proportionality between y/x you investigate the trend in values of x with corresponding values of y
For this case, when x =1, y=3.5
when x=2, y=7
Taking in case 1, y/x = 3.5/1 = 3.5
In case 2, y/x= 7/2 = 3.5
But you know that the constant of proportionality k is given by;
y=kx------------------------making k subject of formula
y/x=k
Hence in this case, your constant of proportionality is 3.5
