Answer:
-51
Step-by-step explanation:
PEMDAS suggests you start with parenthesis
10+9•(-3)2-(7)
10-(27)2-(7)
10-54-7
-51
Answer:
2 years: 9 months
We know that, 1 year =12 months
2 years =2×12 months
=24 months
Given
2 years: 9 months
This can be written as
=
9months
24months
=
3months
8months
=8 months :3 months
Hence, 8 months: 3 months is the simplest form of 2 years :9 months
Step-by-step explanation:
It would be B (530.7) because if you do 3.14 x 13 x 13 (Or to the second power) Then you get 530.66, the round to the nearest tenths
Isn’t that suppose to be with graphs?
The solution of the equations is (-2, -1)
<h3>System of equation:</h3>
2x - 3y = -1
11x - 9y = -13
Using elimination method let multiply the first equation by -3.
Therefore,
-6x + 9y = 3
11x - 9y = -13
5x = -10
x = -10 / 5
x = -2
let's find y as follows;
2(-2) - 3y = -1
-4 - 3y = -1
-3y = -1 + 4
-3y = 3
y = 3 / -3
y = -1
