Answer:
$12
Step-by-step explanation:
Lola has x.
Mary-Ann has 2 1/3 times Lola's amount, so Mary-Ann has (2 1/3)x.
Mary-Ann has $28.
(2 1/3)x = 28
7/3 x = 28
Multiply both sides by 3/7.
x = 28 * 3/7
x = 12
Lola has $12.
Move the decimal so that there is one whole number.
0.00000482 => 4.82
We moved 6 units to the left so:
4.82 * 10^-6

Answer:
d. 84.5
Step-by-step explanation:
You will have to put the numbers in order than cross out one from each side;
70x
80x
83
86
88x
88x
In doing this you have taken out B,E, and F. The answer would have to be somewhere in between 83 and 86, which would be around 84 and 85, so therefore the answer would be 84.5
Answer:
Step-by-step explanation:
The triangle is equilateral. That means that <N = 60 degrees
7x - 3 = 60 degrees Add 3
7x = 60 + 3 Combine the right
7x = 63 Divide by 7
7x/7 = 63/7
x = 9
