Given:
recipe: 2 tsp of butter
Melinda wants to make 40% more servings than the recipe.
2 tsp is equal to 100%
additional of 40% makes it 100% + 40% = 140%
140% * 2 tsp = 2.8 tsp.
The expression that shows the number of teaspoons needed is:
D. 1.4 x 2
Answer:
(b) 4 x = 4 5 is the needed expression to solve for the value of x.
Step-by-step explanation:
Here, the given proportion is simplified as:
Now, to simplify any proportion of the form 
the simplest way is CROSS MULTIPLICATION.
So, cross multiplying 
Similarly cross multiplying , we get:
4 (x) = (9) (5)
or, 4 x = 45
Hence, 4 x = 45 is the needed expression to solve for the value of x.
Answer:
x=50
Step-by-step explanation:
It is a line so it should be 180 degrease. You already have two of the angles and to find the third (x) you just need to subtract them from 180. 180-105=75, and 75-25 is 50, so x is 50.
Answer:
30240 number of ways are there to seat them
Step-by-step explanation:
Total number of ways of arranging 9 people on 9 chairs in circular manners = (9-1)! = 8! =
number of ways A sit always sit next to B = AB together makes a single and
therefore total number of arrangements for this = 7+(AB) = 8 that is 8 persons sitting in circular manner
number of ways = (8-1)! =7! = 5040
likewise number of arrangements for A and C will be = 5040
Total number of ways such that A cannot sit next to B or C = total ways of 9 persons - total number of A always sitting next to B - total number of ways always sitting next to C = 8! - 7!-7!
= 40320- 5040-5040
= 30240
=
