Answer:
4 x (7-x)
Step-by-step explanation:
4 times (multiply) the difference (subtraction) of 7 and a number (seeing as how you don't know that number use a variable, x)
Answer:
Value of x = -7
Step-by-step explanation:
Given:
First angle = 83°
Second angle = 24°
Third angle = (38 - 5x)°
Find:
Value of x
Computation:
We know that sum of all interior angle in triangle is 180°
So,
83 + 24 + 38 - 5x = 180
145 - 5x = 180
-5x = 35
x = -7
Value of x = -7
Answer:
1a) t = 0.17b
1b) $36.03
2) 51,167.50
Step-by-step explanation:
1a) 17% converted to a decimal (divide by 100) = 0.17. Multiply that by the amount of the bill (before tipping) to get the amount of the tip
1b) The bill of $248 represents the entire bill (100%) plus the tip amount (17%) which makes 117%. As a decimal, this is 1.17.
To find what the cost was without the tip, divide the bill total by 1.17
248/1.17 = 211.97. That was the bill before the tip was added.
248-211.97 = 36.03 was the tip added.
2) 5.5% converted to a decimal is 0.055
0.55 x 48,500 = 2667.50
$2,667.50 + $48,500 = 51,167.50
Or, you can use what we did in 1b, and his new salary is 1.055 times 48,500
1.055 x 48,500 = 51,167.50
Answer:
The actual area of the field in square kilometers is 
Step-by-step explanation:
Scale : 1 cm = 50000 km
Area of field on map = 
Now , 1 cm = 5000 km
We are supposed to find the actual area of the field in square kilometers.
So, the actual area of the field in sq. km =
Actual area of the field in sq. km 
Hence the actual area of the field in square kilometers is
28 divided by 8 is equal to 3.5, so one hotdog will cost $3.50
