Answer:

The expressions that we can  use to describe the total grams of food Ariane feeds her animals per day is:

4k+2d

Step-by-step explanation:

It is given that:

  • Ariane feeds her kitten k grams of food 2 times in the morning and 2 times in the evening.

    so, the amount of food she feeds to her kitten in a day= 4k.

  • She feeds her dog d grams of food 1 time in the morning and 1 time in the evening.

  so, the amount of food she feeds to her dog in a day= 2d.

Hence the expressions that we can  use to describe the total grams of food Ariane feeds her animals per day is:

4k+2d

Answer:

x = 9

y = 13

Step-by-step explanation:

Side-Side-Side or SSS means that if all three sides of one triangle are equal to all three corresponding sides of another triangle, then the two triangles are considered to be congruent (equal).

Therefore, GH = PM  ⇒  7x + 8 = 6y - 7

and,            GP = HM  ⇒  8x - 10 = 5y - 3

Rewrite the first expression to make x the subject, then substitute this into the second equation, and solve for y:

         GH = PM  

⇒  7x + 8 = 6y - 7

⇒        7x = 6y - 15

⇒           x = (6/7)y - 15/7

Substituting  x = (6/7)y - 15/7  into GP = HM:

                              GP = HM  

⇒                      8x - 10 = 5y - 3

⇒  8[(6/7)y - 15/7] - 10 = 5y - 3

⇒  (48/7)y - 120/7 - 10 = 5y - 3

⇒                      (13/7)y = 169/7

⇒                               y = 13

Now we have found a value for y, substitute this into one of the expressions and solve for x:

    8x - 10 = 5y - 3

⇒  8x - 10 = (5 x 13) - 3

⇒  8x - 10 = 62

⇒          8x = 72

⇒            x = 9
