Answer:
10
Step-by-step explanation:
I assume it's a rectangle, therefore:
P = 50
a = 15 ft
b = ?
P = 2a + 2b
50 = 2 * 15 + 2b
50 = 30 + 2b
2b = 50 - 30
2b = 20
b = 10
Basically you can write taking from something or using something 20 times. Here are three examples.
- You borrowed 1 dollar from someone 20 times.
- You descend 1 meter at a time (like a submarine).
- There are 20 candies in the jar. Each day you eat 1 candy.
Answer:
13.45
Step-by-step explanation:
HELLO !
Okay so what you do is<em> eliminate the parenthesis </em>in the equation because it really helps
So you would multiply 8 and b
Also multiple 8 and a
You would get 8b and 8a
Your equation would look like ...
2a + 8b + 8a = ...
<em>Now you add the alike things in the equation </em>
8a and 2a are the alike things.
Now you would have ...
10a + 8b = ?
