Answer:
7/150
Step-by-step explanation:
the answer on my pic is wrong sorry
its meant to be 900A = 42 not 990A
In the number 157,562, the one is in the hundred-thousand place.
Step-by-step explanation:
Sum of opposite angles are supplementary,
x + 60 + 3x = 180
4x + 60 = 180
4x = 180 - 60
4x = 120
x = 120 / 4
x = 30
Answer:
-2
Step-by-step explanation:
Using y=mx+c
ax+2y=10
Put y as subject of formula
2y= 10-ax
2y= -ax+10
using point (3,2)
2y= -ax+10
2(3)= -a(2)+10
6= -2a+10
Put a as subject of formula
-2a=10-6
-2a=4
a= 4/-2
a= -2
Answer:
x=+6
Step-by-step explanation:
First, let's divide both sides of the equation by
3
:
⇒
3
x
2
3
=
108
3
⇒
x
2
=
36
Then, let's subtract
36
from both sides:
⇒
x
2
−
36
=
36
−
36
⇒
x
2
−
36
=
0
The left-hand side of the equation is now in the form of a difference of squares.
We can factorise it in the following way:
⇒
(
x
+
6
)
(
x
−
6
)
=
0
Using the null factor law:
∴
x
=
±
6
Therefore, the solutions to the equation are
x
=
−
6
and
x
=
6
.
