This is the concept of algebra, to calculate the proportion of wool in each item we proceed as follows;
Let the amount of wool used for hat be x
amount of wool in sweater will be 5x
the amount of wool used in scarf will be x-5
therefore the total amount of wool will be:
x+5x+(x-5)=550
x+5x+x-5=550
7x-5=550
7x=550+5
7x=555
hence;
x=555/7
x=79
the amount used in hat x=79g
amount used in sweater 5x=395g
amount used in scarf=79-5=74g
Answer:
x ≅ 5.44864209
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.
Answer:
12
Step-by-step explanation:
(10/y + 13) -3
Let y=5
(10/5 + 13) -3
PEMDAS says parentheses first
(2 +13) -3
15 -3
12
Answer:
14G-30
Step-by-step explanation:
3G -9 + 11G -21
14G-30
105 times 15= 1575
57 times 20= 1140
1140+1575= 2715
(2715)(d)= x
x being the total amount the company paid
