Find the value of x
Answers
Answer:
27 degrees
Step-by-step explanation:
12: 180 = 3x - 17 + x + 40 + 2x - 5
180 = 6x + 18
180 - 18 = 6x
162 = 6x
x = 27 degrees
Answer:
Remember the Triangle Angle Sum theory which states that all angles of a triangle add up to 180˚. With this, make the following equation:
(3x-17) + (x + 40) + (2x - 5) = 180
Get rid of parenthesis
3x - 17 + x + 40 + 2x - 5 = 180
Group like terms:
3x + 2x + x + 40 - 17 - 5 = 180
Simplify
6x + 18 = 180
Subtract 18 from both sides.
6x + 18 - 18= 180 -18
6x= 162
Divide both sides by 6
6x/6= 162/6
x= 27
How do I solve this with explanation?
Answers
Answer:
x = 23°
Step-by-step explanation:
[tex]94 + x = 117 \\ \\ x = 117 - 94 \\ \\ x = 23[/tex]
Answer:
x=23˚
Step-by-step explanation:
So, 117˚ is the measurement of the whole angle. 94˚ is the measurement for the angle it's on. To get x˚, subtract 94 by 117.
117˚-94˚=23˚
So, x=23˚
A school needs to buy new notebook and desktop computers for its computer lab. The

hope this helps!!
Answer:
notebook computer= $5500
desktop computer= $5250
notebook and desktop computer= $10750
Step-by-step explanation:
First of all, we multiply $275 by 20 which would give you 5500. Next, we multiply 350 by 15 which gives you 5250. now to add the total number of notebook and desktop computers, we add them both, which results to 10750.

Answer:
12 is 48% of 25
Step-by-step explanation:
One way we can find a percentage of two numbers is to divide, and then multiply our quotient by 100. In this case, the question is: What percent of 25 is 12? We will divide 12 by 25, which gives us 0.48. 0.48 x 100 is 48, which gives us our answer: 12 is 48% of 25.
