For the first Listing Exercise:
(NOT A)
1. 5x + 65 = 5(x + 13) because if you apply distributive property to the one from List B, it would equal the same as List A's answer.
2. 5(x + 1) = 5x + 5 because if you apply distributive property to the equation from List A, it would equal the same as the one from List B.
3. 1 + 5x = 5x + 1 because this is simple commutative property.. switching the placements.
Answer:
a = A/πb
Step-by-step explanation:
To solve this subject of the formulae given that A = πab.
<u>solution</u>
A = πab
the next step is to look for a unique way to get rid of the variables disturbing "a" from standing alone. this variables are π and b, we need to detach dem from a
A = πab
divide both sides by πb
A/πb = πab/πb
A/πb = a
a = A/πb
therefore the value of a in the fomular A = πab is evaluated to be a = A/πb
Answer:
1st number = 17
2nd number = 18
Step-by-step explanation:
Unknown number = x
Since they are consecutive numbers, we add 1 to each other.
=> x + x + 1 = 35
=> 2x + 1 = 35
=> 2x + 1 - 1 = 35 - 1
=> 2x = 34
=> 2x/2 = 34/2
=> x = 17
So, the first number = x = 17
=> Second number = x + 1 = 17 + 1 = 18
1st number = 17
2nd number = 18
Answer:
two lines in the same plane called parallel - b.
Answer: <em>44°</em>
Step-by-step explanation:
<em>Due to x and 136° being on a straight line, they need to add up to 180°</em>
<em>Let's take 180 and subtract it by 136</em>
<em>180-136</em>
<em>44°</em>
