Answer:

A.) -3/4 + 11/4 = <u>2</u>

-3/4 = -0.75

11/4 = 2.75

-0.75 + 2.75 = 2

B.) 3/4 + (-21/2) = <u>-9.75</u>

-21/2 = -10.5

3/4 = 0.75

-10.5 + 0.75 = -9.75

C.) -9 + 6 = <u>-3</u>

D.) 8 + (-4) = <u>4</u>

E.) -1.5 + 1.9 = <u>0.4</u>

-9+6= -3

8 - 4 = 4

-1.5+1.9 = .4

lapo4ka [179]
There are several ways to confirm that the two expressions are equal. One method is to simply factor the first expression and see it you get a result equal to the second expression. An easier method is to set a value for x and substitute it to the two expressions. If the resulting value is that same, this means that the two expressions are equal.

gavmur [86]

Answer:

2\frac{4}{5}\ \ or \ 2.8 \ \ cups

-The total portion fed to the dog is 7/10 cup

  • Canned-3/10
  • Dry=7/10-3/10=4/10

-One week has 7 days. we multiply the dry portion per day by the number of days in a week.

Dry= Total -Canned\\\\=\frac{7}{10}-\frac{3}{10}\\\\=0.40 \ cup\\\\Dry \ per \ Week= Dry/ day\times days\\\\=0.40\times 7\\\\=2\frac{4}{5}\  or\  2.8 \ cups

Hence, Erin feed her dog 2 4/5 0r 2.8 cups of dry food
