Answer:
16
Step-by-step explanation:
Remember to use pemdas:
8÷2(2+2)
First we do whats in parentheses.
= 8÷2(4)
Then we do multiplication and division from left to right
= 4(4)
= 16
So the answer is 16. Remember that multiplication and division have the same priority in pemdas, and you should always do them left to right, because order does matter.
Answer:
B. (4,12)
Step-by-step explanation:
The process is really easy, all you have to do is substitute the numbers of the ordered pairs into the equations.
So like for A. (-5,8)
Putting this into the equation would look like this,
10 * -5 + 2 * 8 The -5 being substituted for the x and the 8 for the y.
This equation equals to -34, not 64.
3 * -5 - 4 * 8 = -47
not equal to -36, so A is eliminated.
For B. (4,12)
10 * 4 + 2 * 12 = 64
3* 4 - 4 * 12 = -36
These equal to both of the given equations.
For C. (2, 10)
10 * 2 + 2 * 10= 40
3 * 2 - 4 * 10 = -34
These are not equal to the given answers of these equations, C is eliminated.
And D. (-3,11)
10 * -3 + 2 * 11 = -8
3 * -3 - 4 * 11 = -53
These are not equal to the given answers of these equations, D is eliminated.
So the only pair that have made both equations true is B.(4,12)
