8(1 - 5x) = 13 in mixed numbers

tangare [24]

Perform indicated multiplications on left side.

8-40x=13 subtract 8 from both sides

-40x=5 divide both sides by -40

x=-5/40

x=-1/8

Note: There are no mixed numbers in this problem.

Answer:

3 shirts and 6 skirts

Step-by-step explanation:

lets call number of shirts x and number of skirts y

so x+y=9

17x+22y=168

multiplying the first equation by 17 we get

17x+17y=153

17x+22y=168

subtracting we get

5x= 15

x=3

and we know x+y=9 so y=6

so 3 shirts and 6 skirts

Choose the missing step in the given solution to the inequality -2x-14>-4+3x

Komok [63]

Answer:

$x$

Step-by-step explanation:

The given inequality is

$-2x-14>-4+3x$

We need to solve the above inequality.

Step 1: Given inequality.

$-2x-14>-4+3x$

Step 2: Add 14 on both sides.

$-2x-14+14>-4+3x+14$

$-2x>10+3x$

Step 3: Subtract 3x from both sides.

$-2x-3x>10+3x-3x$

$-5x>10$

Step 4: Divide both sides by -5. If an inequality is multiplied or divided by a negative number then the sign of inequality will change.

$\frac{-5x}{-5}$

$x$

Therefore, the solution of given inequality is $x$ .
