Answer: 22.4
Explanation:
The pieces of the chords multiply together to get the same result. This is from the intersecting chord theorem.
The first chord has pieces of 10 and x, which multiply to 10*x
This is equal to the other product found by multiplying the pieces 14 and 16 (from the other chord)
10*x = 14*16
10x = 224
x = 224/10 ... divide both sides by 10
x = 22.4
70 * 0.22 = 15.4
70 + 15.4 = $85.40
The total cost is $85.40
Answer: -45
Step-by-step explanation: According the order of operations, or PEMDAS, we first simplify what's inside the parentheses.
So here, we have 7 + -12 which is -5.
When we are adding a negative, think of it as subtracting a positive so 7 + -12 can be changed to 7 - 12 or -5.
Now, we have (-5) (9).
Since a negative multiplied by a positive gives us a negative, -5 multiplied by 9 will give us an answer of -45.
Therefore, (7 + 12) × 9 = -45.
