Answer:
7 fancy shirts and 5 plain shirts
Step-by-step explanation:
f and p are the numbers of fancy and plain shirts
f+p = 12
p = 12-f
20f + 10p = 190
20f + 10(12-f) = 190
20f + 120 - 10f = 190
10f = 70
f = 7
p = 12-f = 5
Point C is located at (4,3)
When rotating 90 degrees counterclockwise Change the X value to the new Y value and then take the opposite of the Y value and make it the x value.
Point C' becomes ( -3,4)
Answer:
option b) 0.079
Step-by-step explanation:
The explanation for this question is given in the attachment below.
Brian has 39 cards and Wesley has 48 cards
Step-by-step explanation:
Let w be the number of cards Wesley has
and
b be the number of cards Brian has
Then
Putting w = 2b-30 in equation 1
Dividing both sides by 3
Putting b=39 in equation 2
Hence,
Brian has 39 cards and Wesley has 48 cards
