Answer:
A.)
Step-by-step explanation:
The answer that you had chosen is correct, because the number line is stating that you are subtracting 5 from 0, giving you -5. Then it is saying that you are subtracting 2 from that, giving you -7.
B.) is wrong, because they are adding the answer of the correct equation with another number, which would equal -12.
C.) is incorrect, because when you are adding a positive with a negative, you are actually subtracting, not adding. When you are doing this, always keep the sign for the answer (negative or positive) with whatever the larger addend is. So in this letter's situation, the equation would look like this: -5 + 2 = -3.
D.) is incorrect because once again, they are taking the original correct answer and subtracting it from another number, which would be -12.
I hope this helps.
129 divided by 5 is equal to 25 with a remainder of 4.
This means that she will need a total of 26 boxes, but only 25 of them will have 5 cupcakes in them. The last one will have 4 cupcakes.
The least common multiple<span> (</span>LCM<span>) of numbers is the smallest number that they all can divide evenly into.
2 = 1 </span>× 2
10 = 1 × 2 × 5
6 = 1 × 2 × 3
Hence, the least common multiple is 1 × 2 = 2.
Answer:
is the answer
Step-by-step explanation:
First we need to substitute X and Y with their respective numbers
Then, following PEMDAS, We just need to simplify
Answer:
Area of the shaded region = 3.46 square units
Step-by-step explanation:
Measure of the interior angle of a regular polygon = 
From the picture attached,
Number of sides of the given polygon 'n' = 6
Interior angle (∠BAF) of the given polygon = 
= 120°
Measure of ∠BAC = 
= 30°
Now we apply sine rule in ΔAGB,
sin(30°) = 
= 
BG = AB[sin(30°)]
= 
= 1
By applying cosine rule in ΔABG,
cos(30°) = 
= 
AG = AB[cos(30°)]
= 
= 
AC = 2(AG)
= 2√3
Area of ΔABC = 
= 
= 
=
Area of the shaded region = Area of ΔABC + Area of ΔFED
= 2(Area of ΔABC)
= 2√3
= 3.46 square units
