−2∣5w−7∣+9=−7 What is the 2 answers for this question

Mathematics
1 answer:
loris [4]4 years ago
5 0
The two possible answers are w = 3 and w = -1/5

These answers can be obtained through solving to the absolute value symbols. 

<span>−2∣5w−7∣+9=−7 ---> subtract 9 from both sides
</span><span>−2∣5w−7∣= -16 ---> divide both sides by -2
</span>∣5w−7∣= 8

Now, because of the absolute value symbols, set the inside equal to 8 and -8 for the two answers. 

5w - 7 = 8
5w = 15
w = 3

AND

5w - 7 = -8
5w = -1
w = -1/5

Team Green and Team Blue play in a competition. Team Green has twelve more points than Team Blue.
valentinak56 [21]

Answer:

Team blue points = 4 points

Team green points = 16 points

Step-by-step explanation:

Let

Team blue points = x

Team green points = (x + 12) points (1)

Team green points = 4x (2)

Equate equation (1) and (2)

x + 12 = 4x

12 = 4x - x

12 = 3x

x = 12/3

x = 4 points

Team blue points = x

= 4 points

Team green points = (x + 12)

= 4 + 12

= 16 points

Team green points = 4x

= 4(4)

= 16 points

Prasad worked 15 hours this week and earned $195. Assuming he is paid by the hour, how much will Prasad earn next week if he is
kati45 [8]

Answer:

$156

Step-by-step explanation:

First you must find out the number of dollars Prasad receives per hour.

Since he earns $195 in 15 hours we can do 195/15 = 13 to find out the amount of dollars he earns per hour which is $13.

Next we must find out how much money he receives when he work for 12 hours so we simply do 13 (payment per hour) * 12 (amount of hours he works) which will give us $156!

This makes sense cuz 156 is a little bit less than 195 and ofc 12 is a little bit less than 15!
