Answer:
2
Step-by-step explanation:
None
Answer:
The correct options are: Option A, C and D
Step-by-step explanation:
We need to choose correct options by solving the given system of equations.

Let:

First Multiply equation 2 by 2 and add both equations.

Now, we will put value of x in equation 2 to find value of y

So, we get x = 3.14 and y = 2.14
Solution set is (3.14,2.14)
The given solution set (2,3) is not the solution of system of equations.
If we put x=2 and y =3 in the first equation:

(2,3) when substituted in the First equation the equation is True.
If we put x=2 and y =3 in the second equation:

So, (2,3) when substituted in the second equation the equation is false.
The correct options are: Option A, C and D
Answer: Choice D. (x/8) - 2 = 5
Work Shown:
x = Aatif's age
x/8 = divide the age by 8
(x/8) - 2 = divide the age by 8 first, then subtract off 2
(x/8) - 2 = 5 .... the previous result is equal to 5
Answer:
angle 6 = 144
angle 7 = 36
Step-by-step explanation:
1 + 4 = 180 so 180 = 36 = 144
corresponding angles are congruent theorem
3 = 36 8 = 144
5= 36
4 = 144
2 = 144
To solve this problem you must follow the proccedure below:
1. You have that Luisa sells a stuffed elephant for $34.90 and <span>the sale tax is 6% of the sale price.
2. Then, you only have to multiply</span> $34.90 by the sale tax, as below:
6/100=0.06
Sales tax on the elephant=$34.90x0.06
Sales tax on the elephant=$2.094
<span>
About how much is the sales tax on the elephant?
</span>
The answer is: $2.094
