−0.85 – (−1.9) +– 2.06 Group of answer choices

-1.01

1.01

3.96

-3.96

−1.01

Step-by-step explanation:

Simplify the expression!

-1.01

Step-by-step explanation:

a double negative equals a positive. -(-1.9) = 1.9

-0.85 + 1.9 = 1.05

when you have a positive number and add a negative number you just subtract the negative number from the positive.

1.05 + - 2.06 = 1.05 - 2.06

1.05 - 2.06 = -1.01

the answer is -1.01

hope this wasn’t confusing!

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

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
