Answer:
<h2>x=50000 dollars ( the average salary of bachelor degree)</h2><h2>the average salary of Masters degree = 2x-40000</h2><h2>2(50000)-40000=60000 dollars</h2><h2>
</h2><h2>
step by step explanation :</h2>
let x be the salary of individual with bachelor degree
Then the average salary of individual with Masters degree is:
(2x-40000)
the combined of two salaries is 110000:
x+(2x-40000)=110000
3x-40000=110000
3x=110000+40000
x=150000/3
<h2>x=50000 dollars ( the average salary of bachelor degree)</h2><h2>the average salary of Masters degree = 2x-40000</h2><h2>2(50000)-40000=60000 dollars</h2>
To answer the problem above, use the concept of ratio and proportion. The ratio between 1 cm to 21 km should be the same as the ratio of 3.1 cm to the actual distance. Let x be the unknown actual distance and mathematically express the situation,
(1 cm/ 21 km) = (3.1 cm / x km)
This equation gives a value for x which is 65.1 km. Therefore, the answer is letter C.
Answer:
D
Step-by-step explanation:
(I'm learning this right now!)
y = 3x - 3
If a line is perpendicular to another line, they have negative reciprocal slopes.
So you would use the slope -1/3.
Use y - y₁ = m(x - x₁) to get an equation in slope intercept form.
Plug the numbers in.
y - 1 = -1/3(x - 3)
y - 1 = -1/3x + 1
y = -1/3x + 2
An equation of a line perpendicular to line CD is y = -1/3x + 2.
Answer:
2/4 x 7/10 = 14/40, or 7/20.
5/6 x 3/4 = 15/24, or 5/8
3/4 x 2/3 = 6/12, or 1/2
3/10 x 4/5 = 12/50, or 6/25
i think you can finish the rest, all you have to do is multiply the numerator and the numerator, and the denominator and the denominator.
numerator = number on the top
denominator = number on the bottom
then put the two results:
[numerator x numerator]
____________________
[denominator x denominator]
hope this helped! ^^
