A number plus itself, plus twice itself, plus 4 times itself is equal to -104
NARA [144]

The scenario will will be represented by: x+x+2x+4x=-104

The number will be -13

Step-by-step explanation:

We have to convert the given situation into the mathematical form

Let x be the number

Then

"a number plus itself"

x+x

"plus twice itself"

x+x+2x

"plus 4 times itself"

x+x+2x+4x

"is equal to -104"

x+x+2x+4x=-104

This can also be written as:

x+x+2x+4x=-104\\8x=-104\\Dividing\ both\ sides\ by\ 8\\\frac{8x}{8}=\frac{-104}{8}\\x=-13

A shop sells 3 types of boots football boots rugby boots and hiking boots sales are usually sold in the ratio 6:2:3 last moth 24
salantis [7]

Answer:

44

Step-by-step explanation:

The sum of the ratios is 6 + 2 + 3 = 11

Let b = total number of boots sold last week

If 24 football boots are sold, the equation representing this =

6/11 x b = 24

To solve for b, divide both sides by 11/6

b = 44 =  total number of boots sold last week
