Answer:
To work this problem out you would do it as if it were just a simple equation
7x-19<16 (you would first have to add 19 to both sides)
7x<35 (then you would divide by 7 to get the variable by itself)
x<5 ( you answer would then be 5)
Step-by-step explanation:
Answer:
£252
Step-by-step explanation:
The ratio of their profit is 9 ; 5 = 9x : 5x ( x is a multiplier )
Bill gets £72 more than Mischa , then
9x = 5x + 72 ( subtract 5x from both sides )
4x = 72 ( divide both sides by 4 )
x = 18
Total received = 9x + 5x = 14x = 14(18) = £252
He can use addition by adding 0.44 and 1.224 together to see how much Vitamin B-12 (so far he has 1.664 in all.) he has right now. then he needs to subtract that amount (1.664) of B-12 he has from the amount of vitamin B-12 (2.4) he needs. That'll be 0.736 of vitamin B-12 he needs to reach the amount of B-12 he needs.
