Answer:
3000 notebooks
Step-by-step explanation:
75000 sheets
each sheet has 8 pages
each notebook has 200 pages so,
75000x8=600000
600000/200=3000
4 feet is bigger because there is only 3 feet in 1 yard
Answer:
The angle measures are 53.5° and 36.5°.
Step-by-step explanation:
We can create a systems of equations, assuming x and y are the angle measures.
Since the two angles are complementary, their angle measures will add up to 90.
x + y = 90
x - y = 17
We can now use the process of elimination, and end up with:
2x = 107
Dividing both sides by two gets us
x = 53.5
Substituting this value into an equation will get us y
53.5 + y = 90
y = 36.5
Hope this helped!
Answer:D
Step-by-step explanation:
Answer:x=1,y=
Step-by-step explanation:Here's one of many ways of solving this system. Since we are already told that
x
=
y
−
3
from the first equation, just plug in
y
−
3
everywhere you see an
x
in the second equation.
So the second equation becomes
(
y
−
3
)
+
3
y
=
13
. Solve this for
y
to get
y
=
4
.
Then, go back to the first equation that says
x
=
y
−
3
and plug in
y
=
4
. So
x
=
1
.
Check your work by plugging in the values.
1
=
4
−
3
and
1
+
3
(
4
)
=
13
, so we are right.
