Answer:
Step-by-step explanation:
In direct proportion, as the first variable increases (decreases), the second variable also increases (decreases). In mathematical statements, it can be expressed as y = kx. This reads as “y varies directly as x” or “y is directly proportional as x” where k is constant in the equation
In this equation, y and x are the two directly proportional quantities and k is a proportionality constant that tells you exactly how they are related (like 10 cents/piece above). On a graph, a direct proportion will look like a straight line and the slope of the line will be equal to the constant k
Answer:
110, 9.1. The total weight of the salt solution is the weight of water plus the weight of salt. So he made 100+10=110 kg of salt solution.
Step-by-step explanation:
F(n)= x+3. This shows that each number in the sequence was a result of adding three to the previous number. So if you plug a number into the formula shown, you will get the following number.
Answer:
A. 3/8*2=6/8
Step-by-step explanation:
Think about a whole number as (whole number)/1
(2/1)
Then multiply
3/8*2/1=6/8
Hope that helps!
Answer:
C. -4/5 x 8/9
the product of a negative number multiplied by a positive number is always negative
