solve: 2x+3y=1
y=-2x+11

Answers

Answer 1

Answer:

(8, -5); x=8; y=-5

Step-by-step explanation:

i'll be solving via substitution

2x+3y=1; y=-2x+11

2x + 3(-2x +11) = 1

2x -6x +33 = 1

-4x = -32

x = 8

2(8) + 3y = 1

16 + 3y = 1

3y = -15

y = -5

(8, -5)

Check:

-5 = -2(8) + 11

-5 = -16 + 11

-5 = -5

That is called supplementary angles, so they add up to 180 degrees
So it would be 57 + x + 23 = 180
Add 57 and 23, which is 80, subtract that from 180, and you would get
x = 100

Mrs. brown has 8 more boys than girls in her class and has a total of 26 students. Determine how many girls and boys are in the class.

May I please get some help ASAP?

Answers

Answer:

There are 9 girls in the class and 17 boys in the class

Step-by-step explanation:

Set up a system of equations where b is the number of boys and g is the number of girls

b + g = 26

b = g + 8

Solve by substitution by substituting g + 8 as b into the top equation

b + g = 26

(g + 8) + g = 26

2g + 8 = 26

2g = 18

g = 9

So, there are 9 girls in the class. There are 8 more boys than girls, so add 8 to this to find the number of boys:

9 + 8

= 17

So, there are 17 boys.

There are 9 girls in the class and 17 boys in the class.

Answer: 9 girls 17 boys
since he has 8 more boys than girls.
The amount of girls 9
More than 8 so
9+8=17
So 17 plus the 9 girls would be 26 students
