meal cost $11.23, and Annas meal cost $7.89. After a tax of 8% and chipsi 5%,
What is the total amount of the bill?
Answer:
$35.53

12.32+11.23+7.89=31.44
31.44*0.08(for the 8% tax)=2.52
31.44*0.05=1.57
31.44+2.52+1.57=35.53

angle1,2 , and angle3 form a straight line. If m angle3 is six more than twice m angle1 m angle2 is 27 less than m angle3 find m angle2
Since it's an angle on a straight line, the value of angle 2 is 23.25°
Angle 1 = m
Angle 2 = m - 27
Angle 3 = 2m + 6
It should be noted that the sum of angles in a straight line is equal to 180°, therefore we need to equate all the angles given to 180°. This will be:
m + (m - 27) + (2m + 6) = 180°
m + m - 27 + 2m + 6 = 180°
4m = 180° + 27° - 6°
4m = 201°
m = 201/4
m = 50.25°
Therefore, angle 2 will be:
m - 27 = 50.25 - 27 = 23.25°

The temperature T of a refrigerator is at least 35°F and at most 41°F. Write a compound
inequality and an absolute value inequality for the temperature of the refrigerator.
The compound inequality for the temperature T of a refrigerator that is at least 35°F and at most 41°F is 35 ≤ T ≤ 41
A compound inequality has two inequality statements joined together
The the temperature of the inequality is represented by T
The temperature T of a refrigerator is at least 35°F and at most 41°F
This means that the temperature falls between 35°F and 41°F
Since the temperature, T, is at most 41°F
This can be mathematically interpreted as
T ≤ 41
The temperature, T, is at least 35°F
35 ≤ T
Combining the two inequality statements 35 ≤ T and T ≤ 41, the compound statement formed is:
35 ≤ T ≤ 41
The compound inequality for the temperature T of a refrigerator that is at least 35°F and at most 41°F is 35 ≤ T ≤ 41

Marisol bought a soda for $1.99 and 6 bags of chips, which cost "m" dollars each. Which equation represents
the total amont, T, that Marisol spent?
The equation which represents the total amount, T, that Marisol spent is [tex]T = 1.99 + 6m[/tex]
Let the total amount spent be T.Let the cost of bags of chips be m.Given the following data:
Cost of soda = $1.99To find the equation which represents the total amount, T, that Marisol spent:
Translating the word sentence into an algebraic expression, we have;
6 bags of chips = [tex]6m[/tex]
The total amount is equal to:
[tex]T = 1.99 + 6m[/tex]

Step-by-step explanation:
A contractor needs to buy nails to build a house. The nails come in small boxes and large boxes. Each small box has 150 nails and each large box has 400 nails. The contractor bought 2 more small boxes than large boxes, which altogether had 1950 nails. Write a system of equations that could be used to determine the number of small boxes purchased and the number of large boxes purchased. Define the variables that you use to write the system.
Answer:
The number of small and large boxes purchased are:
2 small boxes.
6 large boxes.
Step-by-step explanation:
To solve the unknowns, two equations must be established with the information provided:
150X + 400Y = 2700 (the price of the boxes and the final number of nails, where X is the small boxes and Y the large boxes)
Y = 3X (Large boxes are triple the small ones)
Then equation 2 is replaced in equation one and variable X is cleared:
150X + 400 (3X) = 2700
150X + 1200X = 2700
1350X = 2700
X = 2700/1350
X = 2
Finally, the value of X is replaced in equation 2 to find the number of large boxes:
Y = 3X
Y = 3 (2)
Y = 6
