Answer:
Step-by-step explanation:
First you do the division in parentheses and you get (-3/4*8/1) = -24/4 = -6
The new exercise becomes 2/3 *(-6)*1/3
Next, since there are only multiplication we have to do then in order from left to right so we have
-12/3*1/3 = -12/9
We can simplify by 3 and we get -4/3

The given statement is "nine times five less than twice x".
So, twice of x can be written as 2x and nine times five is 9*5.
Now 9*5 less 2x means we need to take out 9*5 from 2x.
Hence, this statement will be converted into an algebraic expression as follows:
2x-9*5
On problems ii, and iii, you just count up the amount of sides on the polygon and add x behind it to create a type of an equation to find the perimeter of that shape that will work as longs as the sides are congruent to each other.
For problems a,b, and c, you just have to calculate what x is. On a, you find what the other side is if one side is 2 and the area is 24. On b you find what the other side could equal if one side is 4 and the area is 16. On c you know what the perimeter is (72) . The longer sides are 2x and the shorter sides are x. SO you divide by the #s and check your work!
