water cost $2 for 8 bottles orange juice cost a $1.50 for 3 bottles which is more expensive per bottle ​

Answers

I believe you can use ratios and multiply both of them like fractions to get the same amount of bottles and compare the prices fairly.


2:8 = 2/8
1.5:3 = 1.5/3


(2/8)3 = 6/24 or $6 per 24 bottles
(1.5/3)8 = 12/24 or $12 per 24 bottles


In conclusion, the latter ($1.50 for 3) costs more than the $2 per 8.


Answer:

orange juice

Step-by-step explanation:

1 water -> 2÷8

                = 0.25

1 orange juice ->1.50 ÷ 3

                    = 0.50

hence, orange juice is more expensive

find for x

Answers

Answer:

120°

Step-by-step explanation:

The angle next to the x will be 40° due to the alternate angles so

x + 40° + 20° = 180° { being linear pair }

x + 60° = 180°

x = 180° - 60°

x = 120 °

Hope it will help :)

Answer:

120˚

Step-by-step explanation:

Since the two lines are parallel, they are alternate angles

So that means that the angle next to x must be 40˚

So 40 + 20 + x = 180 (since it's half a circle)

60 + x = 180

x = 120

(2z+3)(2z+1)=0

z=(-3/2, -1/2) (Or z=(-1.5,-0.5) if they want decimals instead of fractions)

Answer:

Step-by-step explanation:

7z^2 + 8z + 3 = 3z^2

4z^2 + 8z + 3 = 0

2z + 3 = 0

z = -3/2

2z + 1 = 0

How does the graph of a linear function compare with an absolute value function?

Answers

Answer:

In contrast, linear equations can describe values that are negative, zero or positive. As a result, the range of an absolute value function is zero and all positive numbers, while the range of a linear equation is all numbers.

The function inside the absolute value is NOT linear, therefore the graph contains curves.

Brad buys a sandwich. The regular cost is $6. He uses a coupon for 10% off. After that deduction, a sales tax of 5% is added. How much money Brad need to pay for the sandwich?
A. $5.10
B. $5.67
C. $5.94
D. $6.93

Answers

A is the answer to that
The answer is B.

5% of 6.00 = 0.4

6.00 - 0.60 = $5.40

10% of 5.40 = 0.27

5.40 + 0.27 = $5.67

twice the difference of a number and 5 is 7​

Answers

Answer:

8.5

Step-by-step explanation:

The required value of the number is 8.5 which is twice the difference between a number and 5 is 7​.

How to solve this problem?

To solve this problem, we first need to express the given information in terms of a mathematical equation.

The statement "Twice the difference of a number and 5 is 7" can be represented as the equation 2 × (x - 5) = 7, where x is the number we're trying to find.

Next, we can solve this equation to find the value of x. To do this, we can first distribute the 2 on the left-hand side of the equation to get 2x - 10 = 7.

Then, we can add 10 to both sides of the equation to get 2x = 17.

Finally, we can divide both sides of the equation by 2 to get x = 17/2 = 8.5.

Therefore, the required value of the number is 8.5.
