Please help!
fiasKO [112]

Answer:

10

Step-by-step explanation:

let a = amount of apple

let g = amount of grapefruit

14a+25g=340

a+g=2a-2

-a     -a

g=a-2

plug this into your first equation

14a+25(a-2)=340

14a+25a-50=340

              +50  +50

39a=390

a=10

you have 10 apples

Which place is the tenths and what is it rounded to? please answer quick thx​
Lubov Fominskaja [6]

Answer:

Step-by-step explanation:

see attached to identify which is the tenth's place

How you round the tenth's place depends on the digit in the hundredths place.

If the hundredths digit is less than 5, then you keep the tenths place the same (i.e round down)

If the hundredths digit is greater or equal than 5, then you increase the tenths place by 1 (i.e round up)
