How do I solve this proportion?

Answers

Answer 1

Answer: $(3)/(x)=(7)/(10);\ \ \ \ D:x\neq0\n\ncross\ multiply:\n\n7\cdot x=3\cdot10\n\n7x=30\ \ \ \ /:7\n\nx=(30)/(7)\n\nx=4(2)/(7)$

Answer 2

Answer: Okay this should be simple. So take 10 times 3. Because those are diagnal to eachother. 10*3 = 30. Now take 30 divided by 7. 30/7 = 4.28 and rounded would be just 4.2. That's your answer! Hope i helped!

Which interval for the graphed function contains the local maximum? A ( -3,-2)
B (-2,0)
C (0,2)
D (2,4)

Answers

Answer:

Option C is correct .i.e., ( 0 , 2 )

Step-by-step explanation:

We are given with a graph.

To find: Interval of local maximum

We can clearly see from graph that there is only one point of maximum.

Point of maximum is ( 1.55 , 10.8 )

Option A:

Interval is ( -3 , -2 ) means x > -3 & x < -2

but this interval does not contain x-coordinate of point of Maximum.

Thus, this option is incorrect

Option B:

Interval is ( -2 , 0 ) means x > -2 & x < 0

but this interval does not contain x-coordinate of point of Maximum.

Thus, this option is incorrect

Option C:

Interval is ( 0 , 2 ) means x > 0 & x < 2

Here, this interval contain x-coordinate of point of Maximum.

Thus, this option is correct

Option D:

Interval is ( 2 , 4 ) means x > 2 & x < 4

but this interval does not contain x-coordinate of point of Maximum.

Thus, this option is incorrect

Therefore, Option C is correct.

Sue asked a total of 35 points in two games. She scored 6 times as many points in the second game as in the first how many more points did she score in the second

Answers

210 because 35 times 6 is 210 because if you break it apart 5 time 6 =30 bring the 3 times 6 is 18 add 3 from the 30 and you will get 21 and then add 0 to the end of 21 and you will get 210

2 ( 4a - 12 ) + 3a = 6a + 1
