3/5x + 10 = 4/5x - 6
Answer:
80
Step-by-step explanation:
multiply both sides by 5
3x +50 = 4x -30
combine like terms
-x = -80
x = 80

Answer:
Lilly, since the angles are the same we can set the equal to each other, that's the "trick" of this problem
Step-by-step explanation:
3x + 50 = 6x - 10
3x + 60 = 6x
60 = 3x
20 = x
see how I got that?
A number is 11 less than 3 times another number. The sum of the numbers
is 25. What are the two numbers?
Can you please send the work too
Step-by-step explanation:
this is simple use it and enjoy
Step-by-step explanation:
Let x be the first number
Let y be the 2nd number
given,
[tex]x = 3y - 11 \\ x - 3y = - 11[/tex]
as equation 1
and
[tex]x + y = 25[/tex]
as equation 2.
Now we will use elimination method to solve for simultaneous equations.
We will use equation 1 - equation 2 to eliminate x to solve for y.
[tex]x - x - 3y - y = - 11 - 25 \\ - 4y = - 36 \\ y = - 36 \div - 4 \\ = 9[/tex]
Substitute y into equation 2.
[tex]x + 9 = 25 \\ x = 25 - 9 \\ = 16[/tex]
The numbers are 9 and 16.

Brad wants to have available to buy a car in 5 years. How much must he deposit now at compounded monthly to reach that goal?
Group of answer choices
$22,366.96
$12,395.17
$22,905.95
$12,920.84
Answer:
$10,857.8
Step-by-step explanation:
Brad wants to have $17000 available to buy a car in 5 years. How much should he deposit now at 9% compounded monthly to reach that goal?
A = p(1 + r/n)^nt
P = A / (1 + r/n)^nt
P = 17000 / (1 + 0.09/12)^(12*5)
= 17,0000 / (1 + 0.0075)^60
= 17,000 / (1.0075)^60
= 17,000 / 1.5657
= 10,857.8
P = $10,857.8

Step-by-step explanation:
Binaya spent 9/10 of his pocket money. He has Rs 120 left now. Find:. (i) how much money did he spend ? (ii) how much money did he have?
Solving a linear equation we will find that they spent a total of Rs 1.080 and they initially had Rs 1,200.
How much money did he spend?Let's assume that initially they had M money, we know that they spend 9/10 of it, so now they have:
(1/10)*M
And we also know that at the end Binaya had Rs 120, so we can write the linear equation:
(1/10)*M = Rs 120
Solving that for M we will get:
M = 10*Rs 120
M = Rs 1,200
And the amount that they spent is 9/10 of that, so it is:
(9/10)* Rs 1,200 = Rs 1,080
So, they spent a total of Rs 1,080 and they initially had a total of Rs 1,200
