and the equation is 7 ? 7
And since 7 = 7, the symbol is =

If we let x as the amount of money saved per month and m be the number of months:
xm = 300m2 + 120m 180
The quadractic equation would result to:
300m2 + (120-x)m + 180 = 0
Using the quadratic formula we have the following factorization:
(m - ( -120 + x + sqrt (x2 - 240x - 2145600) ) / 600) (m - ( -120 +x - sqrt (x2 - 240x - 2145600) ) / 600) = 0
Answer:
800 M &Ms
Step-by-step explanation:
First, we can operate on the estimate that the proportion of M&Ms of the sample is equal to the proportion of M&Ms in the giant bag.
Therefore,
number of orange M&Ms in sample / sample size = number of orange M&Ms in bag / bag size
3/50 = 48 / bag size
multiply both sides by 50 to remove a denominator
3 = 48 * 50 / bag size
multiply both sides by bag size to remove the other denominator
3 * bag size = 48 * 50
divide both sides by 3 to isolate bag size
bag size = 48 * 50 / 3
bag size = 800 M &Ms
Answer:
36
Step-by-step explanation:
First do -1 - 5, which is -6.
then square -6.
so 6 x 6 equals 36.
