Mari made some treats for a bake sale. When she finished baking, she had 4 more cupcakes than brownies. She had twice as many cookies as cupcakes. Altogether, she had 108 treats.

28 cupcakes

24 brownies

56 cookies

Step-by-step explanation:

Since the question did not tell us what to look for, we can as well look for the amount of each treat used

Let x be the amount of cupcakes

Let y be the amount of brownies

Let z be the amount of cookies

If Mari had 4 more cupcakes than brownies, then;

x = y+4

y = x-41

Also if she had twice as many cookies as cupcakes

z = 2x 2

If she had 108treats in total, then;

x + y+z = 108 3

Substitute 1 and 2 into 3;

x + (x-4)+2x = 108

2x+2x-4 = 108

4x-4 = 108

4x =108+4

4x =112

x = 112/4

x = 28

Hence she has 28cupcakes

Get y

From 1: y = x-4

y = 28-4

y = 24

Hence she had 24 brownies

From 2: z = 2x

z = 2(28)

z = 56

She had 56 cookies

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
