47 - 19 = 28
28/4 = 7
At most they can spend 7 hours
The solution is
T = (47-19)/4
T = 28/4
T = 7
I think that solution is what your teacher is asking for, i'm not certain but ik the answer should be 7 hours.
16. The answer is 1. It means the total amount of the part of the work force.
16. The answer is 24%
Answer: From the figure attached,
Point X is the midpoint of line AC.
Since coordinates of the midpoint of the segment joining endpoints and is given by,
Therefore, coordinates of the point X will be, = (a, a)
From triangle AXB,
Length of AB = 2a
Length of AX =
Length of BX =
=
Length of AX = BX =
Therefore, triangle AXB is an isosceles triangle.
Step-by-step explanation:
Answer:
Answer:
Total number of cards = 32(4) or y=32(4)
Roberto had 128 cards.
Step-by-step explanation:
Consider the provided information.
Part (A)
He gave his four friends 32 baseball cards each.
Let the number of cards he have before giving them to his friends is y.
This can be written as:
y = 32(4)
Part (B)
Now solve the above equation as shown.
y = 32(4)
Multiply 32 with 4
y = 128
Hence, Roberto had 128 cards.
