Step-by-step explanation:
So you have 31/40
3/4=30/40 (multiply by 10/10)
4/5=32/40 (multiply by 8/8)
So, there you have it, 31/40 is right in between those two.
turn it into decimal format. just do the division,. 31 divided by 40 = .775 and 3 divided by 4 = .75 and 4 divided by 5 = .8. all you have to do is the division and once it is in decimal format you can tell which is greater. hope this helps
Answer:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
Step-by-step explanation:
First calculate the value of the 3 shirts as follows:
$ 71.83 - $ 7.99 = $ 63.84.
$ 63.84.
The general equation would be, where x is the value of shirt # 1, and the value of shirt # 2 and z is the value of shirt # 3:
x + y + z = 63.84, then for each shirt would be the following equations:
Shirt #1
x = 63.84 - y - z
Shirt # 2
y = 63.84 - x - z
Shirt # 3
z = 63.84 - x - y
For example, if we give values (always the sum of both under 63.84) to two shirts, x = $ 20, y = $ 30 then the value of shirt # 3 would be:
<em>z = 63.84 - 20 - 30 = $ 13.84</em>
Answer: х=3.
Step-by-step explanation:
А point is missing here: determining the allowable values of x for this equation.
1. Consider the right side of the equation:
The root expression 2x+3 must be greater than or equal to 0.
2x+3≥0
2x≥-3\ |:2
x≥-1,5.
2. Consider the left side of the equation:
the left side of the equation must be greater than or equal to 0.
x≥0.
We get x≥0. ⇒
х=3 ∈ х≥0
х=-1 ∉ х≥0.
The given statement is
all real numbers at least –8 and at most 0
At least means the minimum value which is -8 here. And at most means the maximum value which is 0 here.
So x is in between -8 and 0 incuding -8 and 0. And the compound iequality is
And the correct option is D .
