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

6 times 1/5 (which is also 0.2) is greater than 1
Answer:
The correct answer is 25
Step-by-step explanation:
It is given a quadratic equation,
x² – 8x = 9
<u>To find the number to be added</u>
The given equation be x² – 8x = 9
here we have to add (b/2)² - the square of half the coefficient of x,
Here b = -8
(b/2)² = (-8/2)² = -4² = 16
Add both side with 16
x² – 8x + 16 = 9 + 16
(x - 4)² = 25
(x - 4)² = 5²
