Amy: x skirts Betty: 2x skirts Carol: (2x) + 7 skirts If Amy has 18 less than Carol, than Carol's equation minus 18 equals Amy's equation: [(2x) + 7] - 18 = x +18 +18 (2x) + 7 = x + 18 - 7 -7 2x = x + 11 -x -x x = 11 Input the solution for x into the girls equation to double check. Amy: 11 Betty: 2(x) 2(11) =22 Carol: (2x) + 7 22 + 7 =29 Does Amy have 18 less than Carol? Carol - Amy = 18 29 - 11 = 18 18 = 18 the problem is solved

What is the difference of the fractions? Use the number line to help find the answer

alisha [4.7K]

Answer:

-7/10

Explanation:

Given the expression

$\frac{1}{2}-1\frac{1}{5}$

We can rewrite the expression as:

$\frac{1}{2}-\frac{6}{5}=\frac{5}{10}-\frac{12}{10}$

The number line showing the location of the two numbers is attached below. Therefore:

$\frac{5}{10}-\frac{12}{10}=-\frac{7}{10}$

What is the explicit formula for the sequence 7,2,-3,-8,-13

eduard

You could say that a(n) = 12 - 5n .

Then ...

a(1) = 12 - 5 = 7
a(2) = 12 - 10 = 2
a(3) = 12 - 15 = -3
and so on.
So it seems to work.
