1) -3x -3 -7x = 17
• start by grouping so add -3x and -7x which gives you -10x
• 10x -3 (+3) = 17 +3 = 20 add 3 on both sides)
• 10x (/10) = 20/ 10 = 2
1) x = 2

2) 10x -6 (+6) = 24 + 6 = 30
• 10x (/10) = 30/ 10 = 3
2) x = 3

3) -4 (+4) -5x = -39 +4 = -35
• -5x (/-5) = -35/ -5 = 7
3) x = 7

4) 3x - 5 > 10
this one i don’t understand, is there a typo maybe ?

5) -5x + x + 16 = -3 you can put a 1 to hold the place of x to make it 1x
• (-5x + 1x) + 16 = -3
• -4x + 16 (-16) = -3 -16 = -19
• -4x (/-4) = -19/ -4 = 4.75 or 4 3/4
5) x = 4.75

guapka [62]

Answer:

250

Step-by-step explanation:

36% are rabbits, and 28% are dogs. That means the percent that are hamsters is:

100% − 36% − 28% = 36%

There are 160 dogs and hamsters, which are 28% + 36% = 64% of the pets. Therefore, we can write and solve a proportion:

160 / 64% = x / 100%

x = 250

There are a total of 250 pets.

Using the Exxon data as an example, pretend Penny’s Pickles (a fake pickle company) divides their company into 10,000 shares of

Leviafan [203]

Answer: 2 percent.

Step-by-step explanation:

Here, The Penny’s Pickles (a fake pickle company) divides their company into 10,000 shares of stock.

Therefore total shares = 10000

If we buy 200 of those shares.

Then shares which we have = 200

Thus the percentage of Penny’s Pickles which we have = (Shares which we have/ total shares)×100 = $\frac{200}{10000}\times 100$ = 2%

Therefore, we have 2% shares of total penny pickles.
