Answer:
Step-by-step explanation:
Isolate the variable by itself
8x=23 divide each side by 8
x=23/8 (or 2.875 as decimal)
2x=112 divide each side by 2
x=56
5x=27 divide each side by 5
x=27/5 (or 5.4 as decimal)
14x=5 divide each side by 14
x=5/14
23x=15 divide each side by 23
x=15/23
Bobby eats at a restaurant and his bill comes out to $45.50. He liked his server and decides to leave a 20% tip.
What is the total cost of the bill?
Answer:
$54.60

John needs a plumber to repair the kitchen drain. The plumber charges $85 for the parts that he will need for the repair plus $30 for each hour worked. The maximum amount of money john can spend is $250. Which inequality would represent this situation if x is the number of hours worked?
Answer:
[tex]30x+85y\leq 250[/tex]
Step-by-step explanation:
Cost of each part is [tex]\$85[/tex]
Cost of working one hour is [tex]\$30[/tex]
Let number of hours worked be [tex]x[/tex] and
number of parts bought be [tex]y[/tex].
The maximum amount of money that John can spend is [tex]\$250[/tex].
From the question we have
[tex]30x+85y\leq 250[/tex]
The required inequality is [tex]30x+85y\leq 250[/tex].
If you have 4 red, 3 blue, and 5 green M&Ms and draw an M&M at random, what is the probability of the following. Write your answer as a fraction, decimal, and percent.
1. Red M&M
2. Green M&M
3. Green or Blue M&M
Answer:
1. 0.3333333
2. 0.4166666
3. 0.6666666
Step-by-step explanation:
add them all up for a total of 12. then divide 4 into 12 for the probability of number 1. Next, divide 5 into 12 for the probability of green. Finally, add 3 and 5 to get 8 and divide by 12.
Using the formula you developed in #2, convert 25 degrees Celsius to degrees Fahrenheit. Write your final numerical answer only.
Answer:
77
Step-by-step explanation:
Given
[tex]C = 25[/tex] --- Celsius
Required
Convert to degrees Fahrenheit
The formula is not given. So, I will answer using the general formula.
[tex]F = 1.8C + 32[/tex]
Substitute 25 for C
[tex]F = 1.8 * 25 + 32[/tex]
[tex]F = 45 + 32[/tex]
[tex]F = 77[/tex]

3 * 3 = 9, that alone is bigger than 7.
3 * 3 + 1 = 10.
10 is bigger than 7.
Answer:
No
Step-by-step explanation:
To know if (3, 7) is a solution, plug 3 into the x and 7 into the y.
[tex](3)^{2} +1=7[/tex]
9 + 1 = 7
[tex]10\neq 7[/tex]
Therefore, (3, 7) is not a solution.

Answer: (13.5 , 8)
14 + 13 / 2 = 13.5
14 + 2 / 2 = 8
Answer:
(13.5,8)
Step-by-step explanation:
midpoint formula = [tex](\frac{x_{1} +x_{2} }{2}, \frac{y_{1} +y_{2} }{2})[/tex]
[tex](\frac{14 +13 }{2}, \frac{14 +2 }{2})[/tex] = (13.5,8)
A triangle is shown below what is the measure of
Answer:
70 Degrees
Step-by-step explanation:
All triangles add up to 180 degrees so add 44+26=70 180-70= 110 so remaining angle is 110. A straight line is 180 degrees so using the remaining angle of the blue triangle we find that 180-110=70 so B is 70 degrees.
Answer:
[tex]70\textdegree[/tex]
Step-by-step explanation:
The Exterior Angle Theorem states that in a triangle, the measure of an exterior angle is equal to the sum of its two remote interior angles.
In this case, the exterior angle is ∠[tex]B[/tex] and the remote interior angles measure [tex]44\textdegree[/tex] and [tex]26\textdegree[/tex], so [tex]m[/tex]∠[tex]B=44+26=70\textdegree[/tex]. Hope this helps!
