Answer:
A. (2,10)
Step-by-step explanation:
5x + y = 20
y = 5x
The second equation is already solved for y, so substitute 5x for y in the first equation to find x.
5x + 5x = 20
10x = 20
x = 2
Now substitute 2 for x in the second original equation to find y.
y = 5(2)
y = 10
Answer: (2, 10) which is A.
The megaliter is 10,000 times larger than a hectoliter
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
1 mega liter = 10⁶ Liter
1 hectoliter = 10² Liter.
Hence, a megaliter is 10,000 (10⁶/10²) times larger than a hectoliter

The answer will be 3.008 x 10^20
Solution:
Here we are given with the number 7,889.
we have been asked to find which places contain digits where one digit is ten times the value as the other digit.
Here the number 7889 can be re-written as
Here we can say
So number 100th place is ten times the number in the 10th place.
Answer:
D
Step-by-step explanation:
The sum of supplementary angles is 180°
To find the supplement of 60° subtract it from 180°, that is
second angle = 180° - 60° = 120° → D
