Answer:

x=-10/3

Step-by-step explanation:

negative multiplied by a negative is a positive 

8x+24=2x+4

subtract 24 from each side 

8x=2x-20

subtract 2x from each side 6x=-20

divide both sides by 6 

-20/6 

simply to -10/3 or -3 1/3 or -3.3

x=-10/3

Answer:

266 tickets

Step-by-step explanation:

Ratio of adult tickets to child tickets is 4 : 3

So, if we think of these as "parts", there are 4 parts adult tickets and 3 parts child tickets.

In total there is:

4 + 3 = 7 parts

Now, given 152 adult tickets. If there are 4 parts of adult tickets, how much is each part worth?

152/4 = 38

Total amount of tickets is 7 of these "parts", so total number of tickets is:

38 * 7 = 266 tickets

Sin 167 = 0.22495

cos 107 = -0.29237

cos 167 = -0.97437

sin 107 = 0.95630

(sin 167)(cos 107) - (cos 167)(sin 107)

(0.22495)(-0.29237) - ( -0.97437)(0.95630)

= 0.86602

hope this helps :)

Three days last week Maria ran 3/4 mile 7/8 Mile and 3/5 mile list of distances in order from least to greatest
NikAS [45]

I was taught to get a common denominator and then arrange them in the correct order.

So first you find out what all the denominations can be multiplied to. That would be 40

So you multiply the bottom of each fraction by a number that will get 40.

3/4 * 10 = 30/40

7/8 * 5 = 35/40

3/5 * 8 = 24/40

Then you get 30/40, 35/40, and 24/40.

Then you organize the m.

24/40, 30/40, and 35/40
