Answer:
a = 1
Step-by-step explanation:
Step 1: Write equation
3(a - 1) + 2a = a + 1
Step 2: Solve for <em>a</em>
<u>Distribute 3:</u> 3a - 3 + 2a = a + 1
<u>Combine like terms:</u> 5a - 3 = a + 1
<u>Subtract a on both sides:</u> 4a - 3 = 1
<u>Add 3 on both sides:</u> 4a = 4
<u>Divide both sides by 4:</u> a = 1
For the bottom you could switch the top row with the bottom and you would have to divide instead of multiplying
Multiply each term by
b
and simplify.
a = cb
Rewrite the equation as
cb = a
Divide each term by
c
and simplify.
b = a/ c
14/16
Then reduced it would be
7/8 you leave 16 and add 11 to 3 and get that number
Answer:
610
Step-by-step explanation:
((59 -2) / 3) + 1 = 20
Sum: (2 + 59) x (20 / 2) = 610
It's like a trapezoid with upper base length 2 and lower base 59 and height of 20.
