Answer:

y = 5

Step-by-step explanation:

This is a multi-step equation, so you can solve for the variable 'y' by using a series of steps:

1. Combine like terms:

-4y - 3 = 5 - 3y + 6 -19 or -4y - 3 = -3y - 8

2. Isolate the variable using inverse (opposite operations):

Add 8 to both sides: -4y - 3 + 8 = -3y - 8 + 8 or -4y + 5 = -3y

Add -4y to both sides: -4y + 5 + 4y = -3y + 4y

3. Solve for 'y'

5 = y

Answer: $2\frac{3}{20}$

<u>Step-by-step explanation:</u>

First, convert mixed numbers into improper fractions and simplify all fractions

$\frac{4}{10}$ ÷ $\frac{2}{2}$ = $\frac{2}{5}$

$1\frac{6}{8}$ = $\frac{8(1) + 6}{8}$ = $\frac{14}{8}$ ÷ $\frac{2}{2}$ = $\frac{7}{4}$

Next, find their sum. Remember to find the LCD and convert the fractions so they have like denominators.

Monday + Tuesday = Total

$\frac{2}{5}$ + $\frac{7}{4}$ = Total <em>the LCD of 5 and 4 is 20</em>

$(\frac{4}{4})\frac{2}{5}$ + $(\frac{5}{5})\frac{7}{4}$ = Total

$\frac{8}{20}$ + $\frac{35}{20}$ = Total

$\frac{43}{20}$ = Total

Then, convert the improper fraction into a mixed number

$\frac{43}{20}$ = $2\frac{3}{20}$

146, 74, 38, 20, ? what would the next number be in this sequence?

Anuta_ua [19.1K]

Looking at the numbers, we can see that the differences are 72, 36, and 18. Notice that they are each factors of the next by the same constant 2.

18 * 2 = 36
36 * 2 = 72

There, it means that 18/2 will be subtracted from 20.

20 - 18/2
= 20 - 9
= 11

The next number in the sequence would be 11. Hope this helps!
