Answer:
The benefit of the multiplicative inverse property is when you are dealing with fractional coefficients, you can use the property to solve for the variable.
Step-by-step explanation:
The multiplicative inverse property allows us to take the reciprocal (opposite) of a number and multiply it by the original value to obtain the number '1'. We know that they are equivalent because when we multiply fractions, we multiply the numerators and denominators straight across:
The benefit of this property is in getting rid of fractions in an equation. For example, take the following equation:
4 = 
I can solve for 'x' by using the multiplicative inverse property and multiplying both sides of the equation by 
:
or 8 = x
Answer:
Step-by-step explanation:
if you connect the 2 pointy parts of this shape at the top, what you have is a square. That means that the cut out part is a half circle. To find the area of the shaded portion, subtract the area of the half circle from the area of the square. Let's start with the square, cuz that's the super easy one.
A = s*s so
A = 64 in squared.
Now for the half circle. Let's just do this: let's find the area of the whole circle and then cut it in half, how about?
If the length of one of the sides is 8, then half that length is 4, right? Since the circle is touching the sides of the square, the diameter of the circle is the same as the measure of the side of the square. That means that the radius is 4. The area for the circle is
and filling in:
so
A = 50.24 in squared. Divide that in half and the area of half the circle is 25.12 in squared.
Subtract 25.12 from 64 to get 38.88 in squared
Answer:
30 yd²
Step-by-step explanation:
Hello There!
The shown figure is a trapezoid
The first thing we need to do is figure out what the formula for area of a trapezoid is
where a and b = bases and h = height
we are given all of the dimensions so all we have to do is plug in the values
a = 9
b = 6
h = 4
so we can conclude that the area of the figure is
30 yd²

Answer:
30
Step-by-step explanation:
We can ignore the fact they are similar altogether. It's known that all 3 angles of a triangle add up to 180, so:
180=102+48+m
180=150+m
30=m
Answer:
You wrote:
2*x + 4 = 14
This is not an inequality, so i guess that you wanted to write something like:
2*x + 4 ≥ 14
Now, this means that the left equation is always equal to or larger than 14.
Now, which type of problem this may represent?
Well, 2*x + 4 should represent something that is larger than 14, only that.
Then we can write something like:
"You have 4 dinosaur toys, and in the toy store near your house, they sell packs of 2 dinosaur toys. If you want to have at least 14 dinosaur toys, how many packs can you buy?"
Now x represents the number of packs that you buy.
2*x is the number of dinosaurs in these packs
2*x + 4 is the total number of dinosaurs that you have, when you also count the ones that you previously had.
2*x + 4 ≥ 14
Is the inequality that represents the problem.
