Answer:
142 degrees
Step-by-step explanation:
When you divide a fraction by a fraction, you're really just multiplying by a reciprocal. A reciprocal is the fraction flipped around.
So, 1/8 <span>÷ 1/4 is the same thing as 1/8 x 4/1
Now, you just multiply. 1 times 4 is 4. 8 times 1 is 8.
1/8 x 4/1=4/8
4/8 simplified is 1/2
So that is how 1/8</span><span>÷1/4=1/2</span>
Answer:
x - 6
Step-by-step explanation:
(4x2 + x - 5) - (5x2 - 1)
According to the order of operations, parenthesis come first so we will solve what is in the parenthesis first.
Then we do the multiplication because it comes before addition and subtraction.
4x2 = 8
Now we have 8 + x - 5
Combine like terms and 8-5=3 so we have 3 + x
Now for the second one.
5x2=10
10-1=9
Subtracting this from the first expression we have:
3+x-9 =
x - 6
Answer:
C and D
Step-by-step explanation:
So from the equation <em>y = 1.26x + 9.49</em> we can gather that <em>9.49</em> is an initial value because it has to be added to the number with a variable <em>( 1.26x)</em>
Because <em>1.26</em> has a variable of <em>x </em>and x represents a week, we know that the number<em> 1.26 </em>will increases in value depending on how many weeks have passed.
