Answer:
3/4
Step-by-step explanation:
5 3/8 - 4 5/8
We need to borrow from the whole number
5 becomes 4 and the one becomes 8/8
4 + 8/8+ 3/8 - 4 5/8
4 11/8 - 4 5/8
Subtract the fractions
6/8
Simplify the fractions
3/4
Answer:
Equation B, 10 + 5.50n = y.
Step-by-step explanation:
N is the pounds of shrimp that were purchased. This has no set value, it can change at any time.
Since each pound of shrimp is $5.50, if you wanted to buy 10 pounds of fish you'd pay $55.
If I wanted to write an equation to find the total amount of money that I'd need to pay for n pounds of shrimp, I would use the equation 5.50n. (I don't know if this makes sense lol I'm terrible at explaining ;-;)
Now, it states that he wants an extra 10 dollars to pay for expenses. On top of the 5.50n, he wants an extra $10.
You need to add 10 to 5.50, in order to get the total amount, or y.
The final equation is going to be 5.50n + 10 = y, or choice B.
Answer – Always
A negative number raised to an odd power is always negative. When a negative number is raised to an even power, the pairs of negatives will cancel out; but when it is raised to an odd power, after pairs of the negative sign have canceled each other out, there will still be one minus sign left unpaired, which will not cancel out.

Answer:
The measure of the two angles are 27° and 153° respectively
Step-by-step explanation:
Given parameters
Let the first angle be represented by x°
And the second angle which is supplementary to the first be represented by y°
From the question, we have that y measures 126° less than x.
So, y = x - 126°
Two angles are said to be supplementary if the both add up to 180.
In this case, it means that x and y are supplementary if and only if x and y add up to 180.
x + y = 180
Substitute x - 126 for y
x + x - 126 = 180
2x - 126 = 180 --- collect like terms
2x = 180 + 126
2x = 306 ----- multiply both sides by ½
2x * ½ = 306 * ½
x = 153°
Recall that y = x - 126°
Substituton 153 for x
y = 153 - 126
y = 27°
Hence, the measure of the two angles are 27° and 153° respectively
