Answer:
The lines y = x + 7 and y = 5x - 13 intersect at (3.5,10.5)
Answer:
2.33 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan B = AC / BC
tan 25 = AC / 5
Multiply each side by 5
5 tan 25 = BC
2.331538291 = BC
To the nearest hundredth
2.33 = BC
Product=multiplication
Sum=addition
Difference=subtraction
Quotient=division
Quantity=parentheses
X + y = 125
x - y = 47
---------------add
2x = 172
x = 172/2
x = 86
x + y = 125
86 + y = 125
y = 125 - 86
y = 39
ur 2 numbers are 39 and 86
If he starts with one piece and ends up with 5 pieces, then he makes 4 cuts.
It takes him 8 minutes to do the actual cutting, although he may take breaks
between cuts.
