Answer:
25.
Step-by-step explanation:
Whenever you attempt to solve an equation with multiple operations, remember this: PEMDAS
- Parenthesis
- Exponentiation (exponents)
- Multiplication/Division
- Addition/Subtraction
**THIS IS THE ORDER IN WHICH YOU SHOULD SOLVE EQUATIONS WITH MULTIPLE OPERATIONS.**
First, we solve what is in parenthesis.
20+(5 x 2/5) + 3
5/1 x 2/5 = 10/5 = 2 (simplified)
Then, replace the equation with the answer.
20 + 2 + 3
Secondly, there are no exponents.
There is no multiplication nor division.
However, there is addition.
20 + 2 + 3
20 + 2 = 22
Now, we solve the remaining addition problem.
22 + 3 = 25.
Therefore, 20+(5 x 2/5) + 3 = 25.
Answer:
A
Step-by-step explanation:
-3 1/3 or -10/3, so A is the correct answer.
10 • 6 = 60
10 + 10 + 10 + 10 + 10 + 10

40 + 20 = 60
Answer:
6y^2-7y-3
Step-by-step explanation:
<u>(-7-10y+6y^2)+(4+3y)</u>
<u>-7-10y+6y^2+4+3y </u><u><em>(Plus before brackets means the numbers stays the same)</em></u>
<u>6y^2+3y-10y+4-7</u><u><em> (Arrange them)</em></u>
<u>6y^2-7y-3 </u><u>(Do the maths)</u>

Answer:
=11/4 cm
Step-by-step explanation:
We are finding the perimeter
P = 2(l+w)
l = 3/4 cm
w = 5/8 cm
The common denominator is 8
l = 3/4 *2/2 = 6/8
P = 2(6/8+5/8)
=2(11/8)
=22/8
=11/4 cm (2 1/4 cm)
It says an integer or a fraction, not a mixed number
