Answer:
The answer is 9x-68 :)
Step-by-step explanation:
Answer:
{(-2, -7), (-1, -5), (0, -3), (1, -1), (2, 1)}
Step-by-step explanation:
Consider an element in the set we want to achieve. This element can be written as the ordered pair (x, y), where x comes from the set {-2, -1, 0, 1, 2} and given some value of x, we can find y (with the formula y = 2 * x - 3).
So to begin finding the set of all pairs in the resulting set, we first begin by listing out all values of x in each pair:
(-2, y)
(-1, y)
(0, y)
(1, y)
(2, y)
Now to find y, we use the formula y = 2 * x - 3, and we get
(-2, 2 * (-2) - 3)
(-1, 2 * (-1) - 3)
(0, 2 * (0) - 3)
(1, 2 * (1) - 3)
(2, 2 * (2) - 3)
which simplifies to
(-2, -7)
(-1, -5)
(0, -3)
(1, -1)
(2, 1)
Answer: 1/8
Step-by-step explanation: 3/4 x 1/6 = 24/3 (simplify to 1/8)
Answer:
The answer is 4.
Step-by-step explanation:
In order to get this answer you have to use inverse operations. The inverse operation for multiplication is always division. So, you have to solve the equation 7.5 ÷ 1.75. When getting the answer to that (the answer of the equation above), you get <em>n</em>, as it is only a one-step equation. I hope I could help you.
Answer:
9
Step-by-step explanation:
let the number
=
x
then 4 times the number
=
4
x
and 4 times the number increased by 15
=
4
x
+
15
also 6 times the number
=
6
x
and 3 less than 6 times the number
=
6
x
−
3
equating the two expressions gives the equation
4
x
+
15
=
6
x
−
3
←
solve for x
subtract 6x from both sides
4
x

6
x

15
=

3
⇒
−

x
+
15
=
−
3
subtract 15 from both sides
−
2
x
+
15
−
15
=

3
−
15
⇒
−

x
=

18
divide both sides by

18
−
2
⇒
x
=
9
As a check
(
4
×
9
)
+
15
=
36
+
15
=
51
(

×
9
)
−

=

⇒
the number is 9
