Juan bought 5 cupcakes and 3 bearclaws for 45$. Lily bought 4 of the same cupcakes and 6 of the same bearclaws for 72$. What is
puteri [66]

Answer:

Cup cakes= $3

Bear claws = $10

Step-by-step explanation:

Let the orice of cupcakes be x and the price of bear claws be y

5x+ 3y= 45

4x + 6y= 72

Multiply equation 1 by 4 and equation 2 by 5

20x + 12y= 180

20x + 30y= 360

-18y= -180

y= 10

Substitute 10 for y in equation 1

5x + 3(10)= 45

5x + 30= 45

5x = 45-30

5x= 15

x= 15/5

= 3

Hence the price of cup cakes is 3 and bear claws is $10

A mammal's surface area can be calculated by using the equation S(m) = km where s(m) is the surface area in square centimeters,
Virty [35]

Answer: 706 grams

Step-by-step explanation:

s(m) = km

So 6000 = 8.5m

Divide both sides by 8.5 to isolate m

6000/8.5 = 8.5m/8.5

705.88 = m

m = 706 (rounding up)
