Answer:
192
Step-by-step explanation:
Multiply 3/4 by 256
X = <span>pencils
y = </span><span>pens
x + 1.5y = 7 [</span>Stefan spent $7 at the store]
x + y = 6 [<span>He bought a total of 6 items]</span>
if you take a number .1 of it would be 1/10 of it,
.1 of 10 would be 10 .1 of 100 would be 10 etc
to find .1 of 1/10 all we need to do is 1/10 / 10 = 1/100
to prove our answer is correct just do 1/100 x 10 = 1/10
Radiation from the sun. That depends on the sun.
Answer:
The lines are perpendicular
Step-by-step explanation:
we have
isolate the variable y
----> equation A
The slope of the line A is
-----> equation B
The slope of the line B is
Remember that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In this problem
The slopes of line A and line B are opposite reciprocal
therefore
The lines are perpendicular
