Answer:

Step-by-step explanation:

$x = 5 - 2y \\ y = 3(5 - 2y) - 8 \\ y = 15 - 6y - 8 \\ y = 7 - 6y \\ 7y = 7 \\ y = 1$

$x = 5 - 2y \\ x = 5 - 2 = 3 \\$

In traveling from a dormitory to a certain city, a student went 1/5 of the way by foot, 2/3 of the way by bus, and the remaining

kykrilka [37]

Answer:

Step-by-step explanation:

Now, what we know is that the total distance from the dormitory to the city is 1 if expressed in fraction. What we need to know is the fraction of the journey that is scheduled as the last part.

We can get this by subtracting the fractions of the first two phases from 1.

This goes as follows:

1 - (1/5) - (2/3) = 2/15

Now, we know that the final 8 kilometers constitute a fraction of just 2/5

Hence, we know that 2/15 of the total journey is 8 kilometers.

Let the total journey distance be T. This means that 2/15 of T is 8km

2/15 * T = 8km

T = ( 8 * 15 )/2 = 120/2 = 60km

Find the 23rd term of this sequence -25,-15,-5,5....

notsponge [240]

Answer:

195

Step-by-step explanation:

To find the 23rd term of this sequence, we can use the arithmetic sequence formula $a_{n} =a_{1} +(n-1)d$ where,

$a_{n}$ = $n^{th}$ term

$a_{1}$ = first term

$n$ = term position

$d$ = common difference

$a_{23}=-25+(23-1)10$

$a_{23} =195$

A man invests a certain amount of money at 2% interest and $800 more than that amount in another account at 4% interest. At the

Nookie1986 [14]

X the first account interest = x/100*2 = 2x/100
(x + 800)/100 * 4 =( 4x + 3200)/100
2x/100 + (4x + 3200)/100 = 92
2x + 4x + 3200 = 9200
6x = 6000
x = 1000
