Answer:
x = 8
Step-by-step explanation:
We can see that in the picture that they are similar triangles and that CA is four times VT, so that means that all the sides in triangle TUV are four times those in triangle ABC. We now know that TU is four times AB, and 8 times 4 is 32, so we can say that 5x - 8 = 32. Now, we can add by 8 on both sides to get that 5x = 40. Now, we divide by five on both sides to get that x = 8.
The answer is D. 7x 4y and 1
Answer:
The correct answer is x =9
Step-by-step explanation:
It is given that, the polygons are similar.
Then the ratio of corresponding sides are equal.
<u>To find the ratio of corresponding sides</u>
corresponding sides are
16 and 12 ratio = 12/16 = 3/4
32 and 24 ratio = 24/32 = 3/4
x - 1 and 6
y + 1 and 21
Therefore we can write 6/(x-1) = 3/4
<u>To find the value of x</u>
6/(x-1) = 3/4
24 = 3(x-1)
24 = 3x - 3
3x = 27
x = 27/3
x = 9
Therefore the value of x = 9
To find the mean, you add up all the numbers and divide by the number of numbers in the sequence
28+42+56+70+84+98+112
=490 divide by 7
=70
