Answer:
82
Step-by-step explanation:
m = 4
8m = 4 x 8 = 32
n = 10
5n = 5 x 10 = 50
32 + 50 = 82
Answer:
m = 26
n = 13
Step-by-step explanation:
Use the sine rule
2/5 are girls, therefore 3/5 are boys
3/5 = 24
1/5 = 24 ÷ 3 = 8
2/5 = 8 x 2 = 16
Altogether = 16 + 24 = 40
24 - 1 6 = 8
There are 40 children altogether
There are 8 more boys than girls.
Answer:
B :)
Step-by-step explanation:
Answer:
X is 160. because you can add all the value of x. But first substrate 540 with 100 which is 440. then 1/2x + 1/2x+ (x-15) + (x-25) which is further simplified as x + 2x - 40. then it's further simplified as 3x - 40 = 440. then add 40 with 440 which is 480 then divide it by 3 which is 160. therefore X= 160.
