Solve: 8- (y + 3) = 11
y = 6
y = 3
y=0
y = -6​

Answer:

4

Step-by-step explanation:

First n(AUB)=n(E) - n((AUB)')

So n(AUB) = 40 - 6 = 34

Now all u hv to do is use the formulae,

n(AUB) = n(A) + n(B) - n(ANB)

So when u substitute above values,

34=22 + n(B) - 8

So,

n(B) = 4

Answer:

Was the question meant to say "what is the value of 4x-7 when x=4?" if so the answer is 9.

Step-by-step explanation:

First plug in 4 for x. The equation should then read 4(4) -7

Next use pemdas to solve (multiple 4 × 4 and then subtract 7 to get the answer 9

Answer:

n < -14

Step-by-step explanation:

6 (n+2) < -72

6n + 12 < -72

6n < -72 - 12

6n < -84

n < -84/6

n < -14

Answer:

11

Step-by-step explanation:

QS = QR + RS ➡ 19 = -1 + x + 2x - 7 add like terms

19 = 3x - 8

27 = 3x

9 = x

RS = 2x - 7 so 2×9 - 7 = 11

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

G(1,7) and H(-3,11)

The midpoint is

[tex]M = ( \frac{ - 1 + 3}{2} , \: \frac{7 + 11}{2} ) \\ = ( \frac{2}{2} \: , \: \frac{18}{2} )[/tex]

We have the final answer as

Answer:

Step-by-step explanation:

its not right equation

because

5X - 10 ≠ 2X - 4

Answer:

7. 24

8. -1

9. 28

10. 24

Step-by-step explanation:

substitute values into equations. don't forget the brackets :))

7. 3x + 2y2 Let x = 4, y = 3

= 3(4) + 2(3)2

= 12 + 12

= 24

8. (x + 2)2 - (3x - 2) - 4 Let x = 3

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

= (5)2 - (9 - 2) - 4

= 10 - 9 + 2 - 4

= -1

9. x + 2y - 3z + xyz Let x = 4, y = 3, z = 2

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

= 4 + 6 - 6 + 24

= 28

10. xyz Let x = 4, y = 2, z = 3

= (4)(2)(3)

= 24

Answer:

Step-by-step explanation:

This excercise, focuses on ratio problem, and it has to do with the representation of ratio, since we can represent ratio in different ways. let us represent this ratio in the normal/ usual format.

we will first reduce the given value and represent it in the ratio format

given that for  roller skate race, 48 are boys and,

roller skate race, 64 are girls

we have the ratio as

=48/64 divide both denominator and numerator by 4

=12/16  further divide both denominator and numerator by 4

=3/4

The ratio is 3:4

Answer:

18

Step-by-step explanation:

Product in math terms means to multiply

When the term "a number" is used, you can just put a variable

"Is," tells you what the problem equals

With this information, we can create the equation:

(2/3x) + 6 = 12

Now that we have this equation, we can solve it

(2/3x) +6 = 12            We can subtract 6 from both sides.  

            -6     -6

2/3x = 12                   We can divide the 2/3 from each side.

/2/3         /2/3

x = 18

Hope this helps!

Answer:

1

Step-by-step explanation:

2/3x + 12 = 6

2/3x = -6

x = -6 divided by 2/3

(6 divided 2) divided 3 =1

Answer:

[tex]\large\boxed{x = 7}[/tex]

Step-by-step explanation:

3x - 2(x + 3) = 4x - 9 - x

Start by multiplying 2 by the values in the parenthesis

3x - 2x + 6 = 4x - 9 - x

Subtract 3x - 2x and 4x - x

x + 5 = 3x - 9

Add 9 to both sides of the equation

x + 14 = 3x

Subtract x from both sides of the equation

14 = 2x

Divide both sides of the equation by 2

[tex]\large\boxed{x = 7}[/tex]

Answer:

p = -2

Step-by-step explanation:

5p - 10 = + 4(1 + 3p)

first get rid of the bracquetes:

5p - 10 = + 4*1 + 4*3p

5p - 10 = + 4 + 12p

subtract left and right of = sign by 5p

5p -5p - 10 = + 4 + 12p -5p

0 - 10 = + 4 + (12p -5p)

subtract left and right of = sign by 4

-10 -4 = 4 -4 + ( 7p )

re arrange

7p + 0 = -14

divide left and right of = sign by 7

7/7 p = -14/7

p = -2
