Mathematics

Flauer [41]2 years ago

Answer:

The two numbers are 29 and 18

Step-by-step explanation:

Let x and y be the two numbers

x = 2y-7

x+y = 47

We have two equations and 2 unknowns

Substituting the first equation into the second equation

2y-7+y = 47

Combine like terms

3y -7 = 47

3y-7+7 = 47+7

3y = 54

Divide by 3

3y/3 = 54/3

y = 18

Now find x

x = 2y-7

x = 2*18 -7

x = 36-7

x = 29

The two numbers are 29 and 18

A vendor at the State Fair has learned that, by pricing his deep fried bananas on a stick at $1.00, sales will reach 82 bananas
Tasya [4]

Answer:

Y=-40x+122

Step-by-step explanation:

hello

Due to the nature of the data, it is most convenient to model this problem as a linear function.

To solve this problem we must use the equation that defines a line, then start assigning the corresponding values

y1=82bananas per day

X1=1 dolar

y2=52bananas per day

x2=1.75dolar

line ecuation

y − y 1 = m(x − x 1 )

where

m=slope=\frac{y2-y1}{x2-x1} =\frac{52-82}{1.75-1}=-40

solving:

Y-82=-40(x-1)

Y=-40x+40+82

Y=-40x+122

let's try the result!

Price =1dolar

Y=-40(1)+122=82bananas per day

Price=1.75dolar

Y=-40(1.75)+122=52bananas per day

3/7 x 28/9 x 15/17 ... how do I use cancellation? my answer was 15/17 but thats not the right answer, can someone explain this a
Ne4ueva [31]
First you cancel 7 and 28, and 3 and 9, so that leaves you with 4/3 x 15/17, then you cancel 3 and 15 so you get 4x5/17 which should give you 20/17!

5a - 7 = 0.1a - 0.14
DIA [1.3K]

Answer: a=1.4

move the 0.1a to the other and the 7 to the other side which will make the  7 positive and the 0.1a negative.

5a-0.1= 4.9a

-0.14+7=6.86

dive both sides by 4.9 and you get

67+65+ what gives me 180
Serga [27]

Answer:

48.

Step-by-step explanation:

To find the missing number write out the equation :

67 + 65 + ? = 180.

67 + 65 = 132

To find out how much more we need you can minus 132 from 180.

180 - 132 = 48.

Plug it in to see if it works.

67 + 65 + 48 does equal 180.

Hope this helps,

Davinia.
