The correct answer is 3 degrees.
-7 + 10 Ten degrees higher (+10) than minus seven degrees (-7)
3 When adding a positive to a negative, the answer will be the difference between the two numbers. Whether the answer is positive or negative depends on which number is larger; for instance, in this case, 3 is positive because 10 is larger than 7.
Therefore, the answer is 3 degrees.
Hope this helps!
Answer:
3.12
Step-by-step explanation:
Line up the number in long multiplication form as usual
Multiply each digit on the top by the first to the right on the bottom
Add the products together
Place the decimal the number of digits it is collectively in front of in each factor
Example 5.2 has one behind the decimal and .6 also has one digit behind the decimal collectively that would be two digits behind the decimal.

Write the ratio of corresponding sides for the similar triangles and reduce the ratio to lowest terms.
a. 12/24 = 18/16 = ½
b. 12/18 = 16/24 = ⅔
c. 12/16 = 18/24 = ¾
d. 18/12 = 24/16 = 3/2
Answer:
c. 12/16 = 18/24 = ¾
Step-by-step explanation:
Given
Two similar triangles
Required
Ratio of corresponding sides
To solve questions like this, you have to make comparisons between the similar sides of the triangle.
From the attached file,
Side PQ is similar to Side AB
And
Side QR is similar to Side BC
Also from the attached file
PQ = 12 and QR = 18
AB = 16 and BC = 24
Now, the ratio can be calculated.
Ratio = PQ/AB or QR/BC
Ratio = PQ/AB
Ratio = 12/16
Divide numerator and denominator by 4
Ratio = ¾
Or
Ratio = QR/BC
Ratio = 18/24
Divide numerator and denominator by 6
Ratio = ¾.
Combining these results
Ratio = 12/16 = 18/24 = ¾
Hence, option C is correct
$21 would be the price of all three necklaces. But you need only 1 necklace so divide by 3, and the answer is $7.
