8.03×10^10. move the decimal behind the eight and count the amount of places the decimal moved and that would be your power.
Answer:
y =3x + 12
Step-by-step explanation:
So here's PEMDAS:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
So we will complete this equation in that order. So first is solving the problem within the <u>parenthesis:</u>
<em>(12)</em> ÷ 4 · 7 - 4² ÷ 4 =?
Then we solve all the parts including an <u>exponent:</u>
12 ÷ 4 · 7 - <em>16</em> ÷ 4 = ?
Next, we solve the parts with<u> multiplication: </u>
12 ÷ <em>28</em> - 16 ÷ 4 = ?
Then, we solve for all the <u>division:</u>
<em>0.43</em> - <em>4</em> = ?
If there was any addition we would do that next, but because there is none, we move onto<u> subtraction:</u>
0.43 - 4 = -3.57
So, your <u>answer</u> is -3.57
Answer:
see explanation
Step-by-step explanation:
(a)
The opposite sides of a rectangle are congruent, hence
x + 1 = 5 ( subtract 1 from both sides )
x = 4
Or
x - 1 = 3 ( add 1 to both sides )
x = 4
(b)
The sum of the 3 angles in a triangle = 180°, hence
3y + 2y + y = 180
6y = 180 ( divide both sides by 6 )
y = 30
