Yes. <u>Integers are </u><em><u>whole numbers</u></em><u>.</u> Since 10 & -10 are whole numbers (they have no fractional part), this means that they are integers.
1.7 miles: subtract 1.5 from 3.2 which equals 1.7 (make sure to line up the decimals!)
Answer:
The ordered pair will simply be the point at which these two lines cross. We solve the equations as simultaneous equations.
The solution is the point
(
−
6
,
−
11
)
Explanation:
We solve the set of two equations as simultaneous equations.
Call this Equation 1:
y
=
2
x
+
1
Call this Equation 2:
y
=
x
−
5
Rearrange Equation 2 to make
x
the subject:
x
=
y
+
5
Substitute this value of
x
into Equation 1:
y
=
2
(
y
+
5
)
+
1
=
2
y
+
10
+
1
=
2
y
+
11
Rearranging:
−
y
=
11
y
=
−
11
We can substitute this into either equation to find the value of
x
:
x
=
−
6
That means the intersection of the lines is at the point
(
−
6
,
−
11
)
.

Answer:
$14.975
Step-by-step explanation:
Multiply them togther.
She will earn $920 after working 40 hours.
Step-by-step explanation:
Given,
Amount per hour = $20
Raise = 15%
Raise amount = 15% of Amount per hour
New amount per hour = Amount per hour + raise amount
New amount per hour = 20+3= $23
Total earning after working 40 hours = Amount per hour * 40
She will earn $920 after working 40 hours.
