Use a calculator to work out: (1dp) 2.3 x 6.82 7.74 - 1.09 that is a fraction by the way

2.3588

Step-by-step explanation:

Assuming your problem is:

We multiply the top and subtract the bottom, then divide the results together in the calc.

Rounded to 1 decimal place: 2.4

≈2.36 (read below to make sure.)

≈2.4 (rounded to the tenths place)

Step-by-step explanation:

I'm assuming "--------------" is the fraction symbol.

≈2.36

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
