Answer:
48
Step-by-step explanation:
The answer is not correct because on line one, it should be x/4 - 8 = 4.
On line five, (-x/4)/(-4) is not x, it is x/16!
The correct solution should be:
x/4 - 8 = 4
x/4 - 8 + 8 = 4 + 8
x/4 = 12
x = 48. ![\blacksquare](https://tex.z-dn.net/?f=%5Cblacksquare)
Answer:
LL
Step-by-step explanation:
You are given two congruent legs: BC≅BC and AC≅DC. The fact that it is a right triangle lets you invoke the LL theorem of congruence for right triangles. (This is a special case of the SAS theorem, where the A is 90°.)
Area of a circle is :
![\pi {r}^{2}](https://tex.z-dn.net/?f=%5Cpi%20%7Br%7D%5E%7B2%7D%20)
Where r is the radius.
To find r, you divide the diameter by 2
![\frac{3.7}{2} = 1.85](https://tex.z-dn.net/?f=%20%5Cfrac%7B3.7%7D%7B2%7D%20%20%3D%201.85)
Then,
Answer:
P(Multiple of 3) = 33/100
Step-by-step explanation:
We have 3 + 6 + 8 + 11 + 14 + 16 + 15 + 12 + 9 + 5 + 1 = 100 total rolls
We have 6 + 14 + 12 + 1 = 33 rolls of a multiple of 3
P(Multiple of 3) = 33/100
Answer:
2x - y = -7
Step-by-step explanation:
The equation y = 2x+7 needs to be written in standard form
where A must be positive.
To convert to standard form, subtract 2x from both sides.
-2x + y = 7
Multiply each term by -1.
-1(-2x + y =7)
2x - y = -7
