Answer: it goes up like 10,20,30,40
Step-by-step explanation:
Answer:
A = 68
B = 44
C = 68
Step-by-step explanation:
find x:
68 + x + x - 24 = 180
2x + 44 = 180
180 - 44 = 136
136 / 2 = 68
x = 68
_________________________
68 + 68 + 44 = 180
You want the minimum of the solutions to
x + y = 24
7x - y = 16
There are many ways to solve these equations. Adding them together, you get
8x = 40
x = 5
Since this value is less than 12, it is the smaller number. The smaller number is 5.
Answer: 3x+5=23
Step-by-step explanation:
The answer is D.
Answer:
1. 4.5 g
2. 56.25 g
Step-by-step explanation:
3 % substance solution means :
3 g of dry substance is present in 100 g of solution.
By unitary method:
The weight of dry substance in 1 g of solution = 
The weight of dry substance in 150 g of solution = 
Let the weight of solution be w.
8 % solution contains 8 g dry substance in 100 g.
We have to find the weight of the solution(w) which contains 4.5 g of dry substance.
