Answer:
8x + 9
Step-by-step explanation:
Combine 6x and 2x since they are "like variables" meaning they both contain an x, and write in standard form ax + bx + c
They are equal because you can measure the percentage as a decimal with a maximum of 1.
Answer: IX - 4I ≤ 4
Step-by-step explanation:
In the numer line we can see that our possible values of x are in the range:
0 ≤ x ≤ 8
And we want to find an absolute value equation such that this set is the set of possible solutions.
An example can be:
IX - 4I ≤ 4
To construct this, we first find the midpoint M of our set, in this case is 4.
Then we write:
Ix - MI ≤ IMI
Notice that i am using the minor and equal sign, this is because the black dots means that the values x = 0 and x = 8 are included, if the dots were empty dots, it would be an open set and we should use the < > signs.
Answer:
1/2
Step-by-step explanation:
The answer is 1/2 because the fraction 4/8 can be simplified into 1/2 because they are the same.
Area ABD = 16*12/2
area ABC = 9*12/2
------------------------------
so the ratio of the area ABC to the area of ABD = (9*12/2)/(16*12/2) =
= 9/16
