Given: 5x – 4 + 13x = 5
Combine like terms in the given expression.
⇒ (5x + 13x) – 4 = 5
⇒ 18x – 4 = 5
By addition property of equality, add 4 on both sides to equal to the expression.
⇒ 18x – 4 + 4 = 5 + 4
⇒ 18x = 9
By division property of equality, divide 18 on both sides to equal the expression.
⇒ 
By symmetric property of equality, both sides are equal
⇒ 
Hence, .
what's the question u want me to answer :)
Answer:
119 inches
Step-by-step explanation:
cos 42° = 
b = 160 × cos 42° ≈ 119 in.
The length of an arc in a circle is radius x the angle (Ф).
Mind you angle Ф should be in radian.
In our case we have the arc length & the radius, find the angle (Ф)
Arc Length = Ф x 4 = 10 meters ===> Ф=10/4 =5/2 = 2.5 RADIANS
Now let's convert 2.5 RADIANS into DEGREE:
2.5/π = x/180 ===> x= (2.5 x 180) / π ==>143.239° or 143.24° (A)
(7) The stadium would need to be filled 11 times. This is because the stadium holds <em>almost</em> 100,000 people, so 10 would not be enough. Of course, 10*100,000 is 1,000,000.
(8)It would take Stacy 6,000 minutes to count to 1,000,000 is she remained at the constant rate. You can find this by dividing 1,000,000 by 1,000 to see how many 1,000s it will take to get to 1,000,000. Then, you can multiply that by 6 since each 1,000 takes 6 minutes. This yields a result of 6,000 minutes.
(9) The manager has exactly enough money to buy 100 cars for a price of 10,000 each. You can find this answer by simply multiplying 100 and 10,000 and seeing that it is less than or equal to 1,000,000.
