Answer:
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180 so the third angle in the first triangle is 180 - 60 - 40 = 80
The value of x is 40 because given triangles are have two pair of angles that are equal.
Answer: 
Step-by-step explanation:
For this exercise it is important to remember:
- The Distributive property:

- The multiplication of signs:

Then, given the following expression:

You need to apply the Distributive property. Then:

Now you can combine like terms (or add the like terms). Then you get:

Therefore, the equivalent expression created by combining like terms, is:

Answer:
$1.56
Step-by-step explanation:
You have to divide the cost $12.48 and divide it with the 8lbs and it gives you $1.56, if your not sure that its the right answer than just multiply the answer with the 8lbs, your welcome!
No, because it <em>is not a straight line when graphed.</em>
Answer:
Mariya is 1 year old
Vikram is 7 years old
Step-by-step explanation:
Here, we want to know the present ages of Mariya and Vikram.
Let the present age of Mariya be M and the present age of Vikram be V
From the question, we are told that in 6 years time, Mariya will be as old as Vikram is now
Thus, mathematically;
M + 6 = V ••••••(i)
Furthermore , in 2 years time Vikram will be 3 time older than Mariya
Mathematically;
( V + 2) = 3( M + 2)
V + 2 = 3M + 6
V = 3M + 6-2
V = 3M + 4 •••••••(ii)
So let’s equate the V
3m + 4 = m + 6
3m -m = 6-4
2m = 2
m = 1
But V = m + 6
V = 1 + 6
V = 7
