Answer: X=-7/2
y=-11
Step-by-step explanation:
4x+3=2x-4
4x-2x=-4-3
2x=-7
x=-7/2
y=-7/2*2-4
y=-7-4=-11
5 quarters, 15 dimes
q + 10 = d
0.25q + 0.1d = 2.75
0.25q + 0.1(q + 10) = 2.75
0.25q + 0.1q + 1 = 2.75
0.35q = 1.75
q = 5
Check:
0.25(5)+ 0.1(15)= 2.75
1.25 + 1.5 = 2.75
2.75 = 2.75 :)
Answer:
Explanation:
Use the Pythagorean theorem (
a
2
+
b
2
=
c
2
)
Lets label the right triangle such that:
a
=
12
b
=
16
c
=
x
Thus,
12
2
+
16
2
=
x

144
+
256
=
x

400
=
x
2
√
400
=
x
20
=
x
So our missing side,
c
is
20
We can now say that the sides of our triangle are
12
,
16
,
20
I've included a link that lists a couple of Pythagorean triples (a couple because they are infinitely many).
