Answer: 3.33

Step-by-step explanation:

The answer is 3.33. You get that by dividing the x value in the ordered pair by the y value.  

The ordered pair was (40, 12). The x value is 40 and the y value is 12.

Divide 40 by 12 and you get 3.33

Answer:

Step-by-step explanation:

Given the decimal value 588.55

The ones digit value is 8

The tens digits value is 80

Taking the ratio

The ones digits/the tens digits = 8/80

The ones digits/the tens digits = 1/10

The ones digits = 1/10 * the tens digits '

Hence the value of the ones digit is 1/10 of the value of the tens digit.

Hudson went into a grocery store and bought 5 peaches and 7 mangos, costing a total of $16. Austin went into the same grocery st
strojnjashka [21]

Answer:

the mango cost 1.75$ each and the peach 0.75$

Step-by-step explanation:

M= mango

P=peach

we know that Hudson spend 16$ buying 7 mangos and 5 peaches. So we can write the equation

(1) 16=7M+5P---> (2)P=(16-7M)/5

and we know that Austin spend 14.50 buying 4 mangos and 10 peaches.

we write the equation

(3)14.50=4M+10P

and we replace the P with the equation (2)

14.5=4M+10*(16-7M)/5

14.5=4M+2*(16-7M)

14.5-32=4M-14M

M=1,75$

and now we replace M in eq. (2)P=(16-7*1.75)/5=0.75$
