First number multiply by 3 for the next number subtract 10 and repeat process
First multiply the 2 into the parenthesis. Then add the 10 and 2 in order to simplify. Then subtract 4a from both sides. This gives you 12=3a-3. Add 3 on both sides, this gives you 15=3a. Divide 3 on both sides which will give you a =5
Tangent 3 degrees = height / 1,000
height = tangent (3) * 1,000
height = 0.052408 * 1,000
height = 52.408 meters
Answer:
(2/3)n + 7
Step-by-step explanation:
Represent the number by n.
Then "two thirds of (that) number" is (2/3)n.
Finally, we add 7:
"Two-thirds of a number increased by seven" is (2/3)n + 7
The answer is 69.5 because all you have to do is 139/2
