Answer: The sum of their ages is 42
Step-by-step explanation:
This can be translated to:
in 15 years from now, Jorge's age will be 2 times the age of Eduardo.
If 6 years ago the age of Jorge was the triple of the one of Eduardo.
Find the sum of their ages:
If E is Eduardo's age and J is Jorge's age, we have a system of equations:
J + 15 = 2(E + 15)
J - 6 = 3*E
The first step is isolating one of the variables in one of the equations, let's isolate J in the second equation:
J - 6 = 3E
J = 3E +6
Now we can replace it in the first equation:
J + 15 = 2E
3E + 6 + 15 = 2E + 30
3E + 21 = 2E + 30
3E - 2E = 30 - 21 = 9
E = 9
Eduardo is 9 years old:
J = 3E + 6 = 3*9 + 6 = 27 + 6 = 33
Jorge is 33 years old.
then E + J = 33 + 9 = 42
The answer you are looking for is option C, ten feet!
1 yard = 3 feet, so, when we have 3 yards, it is 9 feet! Then, we add a foot making the answer 10! Hope this helps! :)
The two inside angles add up to the external angle's total. The m∠1 will be 69°. Option D is correct.
<h3>What is angle measurement?</h3>
An angle measure is the measurement of the angle created by two rays or arms at a shared vertex in geometry. A protractor is used to measure angles in degrees (°).
From the exterior angle property, the sum of the exterior angle is the sum of the two interior angles.
The m∠1 will be 69°.
Hence, option D is correct.

Answer:
$182000000000
1.82 * 10^11
Step-by-step explanation:
Given that :
Number of engineers = 2.6 million
Average salary = $70,000
Collective income generated by group of engineers yearly :
This will be on average :
2,600,000 * 70,000 = $182000000000
In scientific notation :
$182000000000 = 182 * 1000000000
182 * 1000000000 = 182 * 10^9
182 = 1.82 * 100 = 1. 82 * 10^2
Hence,
$182000000000 = 1.82 * (10^2 * 10^9)
$182000000000 = 1.82 * 10^11
