Answer: Question 3: 2x-4
Question 4: -2x+8
Step-by-step explanation:
in the first one you multiply the 2 into each part of the parenthesis
in the second you add all of the ones with the "x" on them and then add both of the 4's together
Answer:
Hi
The answer is C
Step-by-step explanation:
Because it descend means goes down so it's minus and after that it ascends means goes up so it's plus so the answer will be -
26,843-1,284+5832
Given:
Total number of marbles = 15
Probability of randomly selecting a green marble = .
Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble = .
To find:
The number of blue marbles.
Solution:
Let the number of blue marbles be x.
It is given that,
Probability of randomly selecting a green marble, replacing it, and then randomly selecting a blue marble is . So,
Multiply both sides by 75.
Therefore, the number of blue marbles in the bag is 6.
Both triangles are similar. The area of the smaller triangle is about 270 ft2. Which is the best approximation for the area of the larger triangle? small traingle side is 25ft the bigger traingle side is 35ft.
We know the relation between the area of similar triangles and the side length
=
area of the smaller triangle= 270 ft2
Let the area of bigger triangle =x
small traingle side=25ft
the bigger triangle side = 35ft
Ratio of sides is 25 : 35 that is 5:7
Now we make a proportion
=
270/x = 25/49
Cross multiply it
270 * 49 = 25 * x
13230 = 25x
divide by 25 on both sides
So x= 529.2
Area of larger triangle is approximately 530 square feet.
