For number 3 it says
X - 9 for x=-5
X-9 = ___ -9
It gave you your x so you would just substitute and in result you will have an equation of -5 -9
It would give you -14 , since it’s 2 negatives being added ,because you double tapped . Hope this helps :)

This circle graph shows how Jimmy spent his time during the last 24 hours.
MariettaO [177]

Answer:

Excess time = 1.2 hour

Step-by-step explanation:

Given:

Total time = 24 hours

Talking on phone = 17 %

Sleeping = 33%

Going to school = 25%

Studying = 4%

Eating = 8%

Computation:

Watching TV percent = 100% - Talking on phone - Sleeping - Going to school - Studying -  Studying - Eating

Watching TV percent = 100% - 17% - 33% - 25% - 4% - 8%

Watching TV percent = 13%

Time taken by school = 24 x 25%

Time taken by school = 6 hour

Time taken by watching T.V. and Talking on the Phone = 24 x (13% + 17%)

Time taken by watching T.V. and Talking on the Phone = 7.2 hour

Excess time = 7.2 - 6

Excess time = 1.2 hour

Solve the two step equations
disa [49]

Hello!

1) -3x - 4 = 23

-3x = 23 + 4

-3x = 27

x = 27 : (-3)

x = -9

2) x/2 - 12 = -4

x - 24 = -8

x = -8 + 24

x = 16

3) 6a + (-1) = 10

6a - 1 = 10

6a = 10 + 1

6a = 11

a = 11 : 6

a = 11/6

4) -(x + 2) = 12

x + 2 = -12

x = -12 - 2

x = -14

5) 7a + 12 = 10

7a = 10 - 12

7a = -2

a = -2 : 7

a = -2/7

6) -4(a + 2) = 12

a + 2 = -3

a = -3 - 2

a = -5

Good luck! :)

Delvig [45]

Answer:

Below.

Step-by-step explanation:

Letter P is drawn - Impossible because there is no paper with P on it.

Letter drawn is a consonant - Likely because there are 6 out of 8 letters which are consonants.

Letter drawn is a vowel - Unlikely because there are only 2 vowels out of 8 letters.

Letter drawn is one of the first ten letters in the alphabet - Equally likely as there is 4 of these out of a total of 8.

Letter is L - Unlikely as there is only 1 piece of paper with L on it.

The paper draw has one letter on it  - Certain as there is a letter on all the pieces of paper.

What value does each equation need to be multiplied by in order to eliminate the y terms equation 1 6x-5y=-4 equation 2 4x+2y=28
Alex777 [14]
In order to eliminate the y term, you need to find what y is equal to in the equation.
1. 6x-5y=-4
-5y=-4-6x
Y=6/5x+4/5
You then sub in 6/5x+4/5 in for y in the equation
2. 4x+2y=28
2y=-4x+28
Y=-2x+14
Hope this helps!
