Answer:
72 marbles are yellow
Step-by-step explanation:
The equation 0.15 x + 150 ≥ 450 will help Teagan determine how much he has to sell today ⇒ A
Step-by-step explanation:
The given is:
- The computer store pays its employees $150 per day plus a commission of 15% of their sales
- Teagan wants to make at least $450 today
We need to find which equation will help Teagan to determine how much he has to sell today
Assume that he has to sell by $x today
∵ The store pays $150 per day plus a commission of 15%
of their sales
∵ Teagan's total sales = x
- Multiply 15% by x, then add the product by 150
∴ Teagan makes = 15% × x + 150
∵ 15% × x =
× x = 0.15 x
∴ Teagan makes = 0.15 x + 150
∵ Teagan wants to make at least $450 today
- At least means ≥
∴ Teagan makes ≥ 450
- Substitute Teagan makes by 0.15 x + 150
∴ 0.15 x + 150 ≥ 450
The equation 0.15 x + 150 ≥ 450 will help Teagan determine how much he has to sell today

Try the first one, it looks right since it’s all in sequenced right
The first one is 4, the second one is 30, and the third one is 48. If you get a number from the sugar you divide it by three, and if you get a number from the flour you multiply it by three

<span>Borders are interesting because you have to remember that you have to pave the 4 corners.
.
The area of the garden = 12*16 = 192 square meters.
.
Then you add the border with width 'x'.
So,
Length is now L + 2x
Width is now W + 2x
.
We are told:
(L+2x)(W+2x) = 285
.
(12+2x)(16+2x) = 285
.
192 +24x +32x +4x^2 = 285
.
4x^2 + 56x + 192 = 285
.
4x^2 + 56x - 93 = 0

For these solutions to exist, the discriminant should not be a negative number.
First, we need to compute the discriminant : .
Discriminant d=4624 is greater than zero. That means that there are two solutions: .
Quadratic expression can be factored:
Again, the answer is: 1.5, -15.5. Here's your graph:

.
You cannot have a negative width, so the border is 1.5 m.
.
Always check your work.
L = 12 + 2(1.5) = 15
W = 16 + 2(1.5) = 19
15*19 = 285
Correct.
.
Answer: The border is 1.5 meters wide.
