First you figure out how much money she used so $25 - $20.14 which is equal to $5.86. Now you need to figure out how much minutes that is equal to $5.86. So you need to figure out what x is equal to in: x * <span> ¢</span>18 = $5.86.
x is equal to 32.555555
so she was calling for 32.555555... minutes or if you are rounding it would be 32.6 minutes
hope this helps ^^
A rhombus is a shape that has all four sides equal, whether they be in the shape of a parallelogram, or a square, if it has all four sides equal length, it's a rhombus. The definition of a rectangle, is a shape that has four right angles. (90 degrees).
So, if a square has all four sides equal, and four right angles, it can be both a rhombus and a rectangle.
Not all rhombuses are squares, because not all have four right angles. Not all rectangles are squares, because they do not all have four equal sides. Not all rectangles are rhombuses because they do not have four equal sides.
But all squares are a rhombus and all squares are a rectangle.
Subtract 39 from both sides
-7x = -4 - 39
Simplify -4 - 39 to -43
-7x = -43
Divide both sides by -7
x = -43/-7
Two negative make a positive
<u>x = 43/7</u>
<em>For the second equation;</em>
Simplify brackets
7x + 7 = 4
Subtract 7 from both sides
7x = 4 - 7
Simplify 4 - 7 to -3
7x = -3
Divide both sides by 7
<u>x = -3/7</u>
Answer:
72 grams
Step-by-step explanation:
If one marshmallow weighs 7.2 all you have to do is take that times 10, which would give you 72 grams as the answer.
