Answer:
20
Step-by-step explanation:
10^2 = 10 x 10 = 100
5^1 = 5 x 1 = 5
100/5=20
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:
1. 62
2. 13
3. 6
4. 18
5. 3
Step-by-step explanation:
1. Let's use pemdas
16*1/2= 8
32 / 4 * 8 - 2
8*8 - 2
64 - 2
= 62
2. Let's use pemdas
5*2/5 = 2
20 / 2 + 3
10 +3
= 13
3. Let's use pemdas
1/2 * 24 / 3 +2
12 / 3 +2
4 +2
=6
4. Let's use pemdas
2 * (6 / 2 + 8) -4
2 * 11 - 4
22 - 4
= 18
5. Let's use pemdas
(28 / 7 +6 / 3) * 1/2
( 4 + 2) *1/2
6 *1/2
= 3
