Answer:

x=-3

Step-by-step explanation:

So we have the equation:

-2(-x-4)+3=-7-4x

First, distribute the left side:

-2(-x)-2(-4)+3=-7-4x\\2x+8+3=-7-4x

Add values on the left side:

2x+11=-7-4x

Add 7 to both sides. The right side cancels:

(2x+11)+7=(-7-4x)+7\\2x+18=-4x

Subtract 2x from both sides. The left side cancels:

(2x+18)-2x=(-4x)-2x\\18=-6x

Divide both sides by -6:

(-6x)/-6=18/-6\\x=-3

Therefore, x equals -3.

Answer:

x =  - 3

Step-by-step explanation:

- 2( - x - 4) + 3 =  - 7 - 4x

to \: get \: rid \: of \: the \: parenheses \:  \\ distribute \: two \: through \: the \: parentheses

2x + 8 + 3 =  - 7 - 4x

add \: the \: numbers \\  \\2x + 8 + 3 =  - 7 - 4x \\  \\ 2x + 11 =  - 7 - 4x \\  \\ move \:  - 4x \: to \: the \: left - hand \: side \: and\: change \: its \: sign \\  \\ 2x + 4x + 11 = - 7 \\  \\ move \: constant \: to \: the \: right - hand \: side \: and \: change \: its \: sign \\  \\ 2x + 4x =  - 7 - 11 \\  \\ 6x =  - 18 \\  \\ x =  - 3 \\  \\  \\ hope \: this \: helps \:

Mary is preparing for her college entrance exams in a practice test she answered 12 problems in 30 minutes at this rate how many
kap26 [50]

Answer:

40 problems in 100 minutes

Step-by-step explanation:

This is a ratio problem.

You first divide 30 minutes by three to get how many problems she can do in 10 minutes. What you do to one side you do to the other side. So then, you should have 4 problems in 10 minute. Then, you multiply 10 by 10 and 4 by 10 to get 40 problems in 100 minutes.

in Ryan's V. Class 50% of the students like the teacher if 15 of the students like the teacher how many students are in that cla
Anton [14]

Answer: 30 students.

Step-by-step explanation: They are saying 50% of the class like the teacher. We know that 50% is half of the 100% so that mean only half of the students like the teacher. Is 15 students like the teacher it means that 15 are half of the students in the class. The other half should be another 15. So 15+15=30 or 15x2=30.

I hope I didn’t make it to confusing.
