7a + 5 (a + 3) = 8a + 4 (a + 2)

Answers

Answer:

[tex]no \: solution[/tex]

Step-by-step explanation:

1) Expand.

[tex]7a + 5a + 15 = 8a + 4a+ 8[/tex]

2) Simplify 7a + 5a + 15 to 12a + 15.

[tex]12a + 15 = 8a + 4a+ 8[/tex]

3) Simplify 8a + 4a + 8 to 12a + 8.

[tex]12a + 15 = 12a + 8[/tex]

4) Cancle 12a from both sides.

[tex]15 = 8[/tex]

5) Since 15 = 8 is false, there's no solution.

[tex]no \: solution[/tex]

(I forgot to place the picture) A local taxi company charges a base fare of $3.20. The taxi company charges $0.40 for every minute the taxi is in service.

Answers

Answer:

5 minutes costs 5.20 10 minutes cost 7.20 $20 gets you 42 minutes

Step-by-step explanation:

for 5 and 10 multiply the number of minutes by the price per minute then add 3.2 base fee.  5*.4=2 +3.2=5.2      10*.4=4 +3.2=7.2

For $20 subtract the 3.2 base fee (16.8) and divide that by the .4 a minute fee to get 42 which would be 42 minutes.

Rename 5/6 and 14/15 using the least common denominator.

Answers

Answer:

25/30 and 28/30

Step-by-step explanation:

1. To find the least common denominator, you need to find the least common multiple of the two denominators which are 6 and 15. Prime factorization of these numbers gives:

6 = 2 x 3

15 = 5 x 3

A number that would evenly divide both 6 and 15 must contain 2 x 3 x 5 which is 30.

Thus 30 is the least common denominator.

2. Now we need to somehow change both fractions to make them have a denominator of 30. To do this we can multiply by fractions with same numerator and denominator since that would be like multiplying by 1.

So, 5/6 x 5/5 = 25/30

And 14/15 x 2/2 = 28/30

A balloon is floating above a lake and a sunken canoe is below the surface of the lake. The balloon’s vertical position is 12 meters and the canoe’s is -4.8 meters. The equation  represents this situation.

Answers

Complete question :

A balloon is floating above a lake and a sunken canoe is below the surface of the lake the balloons vertical position is 12 meters and the canoes is -4.8 meters the equation the equation 12+d= -4.8 represents the situation 1. What does the Variable d represent 2. What value of d make the equation true

Answer:

d = lake

d = - 16.8

Step-by-step explanation:

The scenario described is represented by the equation :

12 + d = - 4.8

The variable d in the equation would refer to the surface of the lake. Hence, the lake is represented as d ;

For the equation above to be true such that the position of canoe is - 4.8

The we solve for d in the equation given :

12 + d = - 4.8

12 + d - 12 = - 4.8 - 12

d = - 16.8
