To check, we can solve how much sunscreen is in a family sized bottle first. We need to find what is 20% of 12. First, turn 20% into a decimal: 20%/100= 0.2. Now, multiply 0.2 by 12, which is 2.4. Then, you add this to 12 because it is 20% more. 12+2.4= 14.4. Multiply this by 4: 14.4*4=57.6. Since his number is close to 50, he is kinda correct, but a much more reasonable answer would be closer to 60. Hope this helped!
"The least common multiple (LCM) is the smallest number which is a multiple of two numbers. If two numbers have no common factors greater than 1, then their LCM will be their product. For example, take numbers 7 and 9. They have none common factor greater than 1."
Answer:
m = 1 and c = - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 5 is in this form
with m = 1 and c = - 5
Answer:
( 4 x 10 y )
Step-by-step explanation:
The solution is a pair of numbers ... one for 'x' and one for 'y' ... that
makes the equation a true statement. There are an infinite number
of solutions. If you use the equation to draw a graph, then the graph
of it is a straight line without ends, and <em><u>every point</u></em> on the line is a
solution to the equation.
Here are a few of them:
(In each pair, the first number is 'x', the second number is 'y'.)
