The number of white sweatshirts is 28
Step-by-step explanation:
Let ordered black shirts be represented by b
Let ordered white shirts be represented by w
So total sweatshirts will be represented by the equation
b+w=50
The total cost of the ordered sweatshirts will be represented by
10b + 12 w= $556
For simultaneous equations as;
b+w=50
10b+12w=556
solving the equations using substitution method where b=50-w
10(50-w)+12w=556
500-10w+12w=556
-10w+12w=556-500
2w=56
w=56/2= 28
b=50-w=50-28=24

<span>Y is directly proportional to x^2. It could be represented by the expression:
y </span>α x^2
We can make it into an equality by inserting the proportionality constant, k.
y = kx^2
k would be constant for any value of y with a corresponding value of x. We solve the problem by this concept as follows:
y1/(x1)^2 = y2/(x2)^2
10/(x1)^2 = y2/(x1/2)^2
10/4 = y2
Therefore, when the value of x is halved, y is equal to 10/4.
No, he almost earns $400
9.20 / 1.5 = 6.13
9.20 - 6.13 = 3.07
9.20 + 3.07 = 12.27
12.27 x 2.25 = 27.61
9.20 x 40 = 368
368 + 27.61 = 395.61

*I'm going to assume you meant stripes.
Answer:
So in total there are 15 chips in the bag.
9 of them are stripes and 6 are numbers.
Step-by-step explanation:
So there are 9 stripes in the bag.
The probability of getting a stripe is 3/5
This means that for every 5 chips that the contestant pulls out, 3 of them should be stripes. This also means 2 of them are numbers.
So we know that 9 of the chips in the bag are stripes. To find the total number of stripes we should divide 9 by 3/5:
So we get:
