Answer:

Drink=5.75

Popcorn=1.83

Percentage for drink=75.9%

Step-by-step explanation

Let the popcorn be p

the drinks be d

6p+4d=34....(1)

12p+7d=66.25...(2)

Multiply (1) by 2

12p+8d=72....(3)

Substrate (2) from (3)

d=5.75

Substitute the value for d into (1)

6p+4(5.75)=34

6p+23=34

Substrate 23 from both sides

6p=11

Divide both sides by 6

p=1.83

So for one drink=$5.75

For one popcorn=$1.83

To determine the% for drink

5.75+1.83=7.58

5.75/7.58 ×100

575/7.58

75.858~75.9%

The percentage for drink is 75.9%

Find the area of the rhombus.<br> A=<br> square units

mylen [45]

Answer: A=70 square units

Step-by-step explanation:

The area of a triangle can be found using the formula $A=\frac{1}{2} bh$

Let 5=h and 7=b

Plug in the values and solve

$A=\frac{1}{2} (7)(5)$

$A=17.5$

However, since four of these triangles make up this rhombus, we can multiply the area of one of these triangles by four to find the area of the whole rhombus.

$A=17.5*4$

$A=70$

If y=x³+x²-2x+1, it is possible for y to be a cubic number?

Damm [24]

Answer:

Below.

Step-by-step explanation:

Yes, because if x = 1:

y = 1^3 + 1^2 - 2 + 1

= 2 - 2 + 1

= 1 which is a cubic number.

9y + 9 - 3y + 7 = 2y + 4<br><br> y = Answer

DENIUS [597]

Answer:

y = -3

Step-by-step explanation:

9y + 9 - 3y + 7 = 2y + 4

Collect like terms;

6y + 16 = 2y + 4

Subtract 2y from both sides;

4y + 16 = 4

Subtract 16 from both sides;

4y = -12

Divide both sides by 4;

y = -3
