I need help solving this​

Answer:

p = 3

q = 4

Step-by-step explanation:

p + 2q  = 11          --------------------(I)

       p = 11 - 2q

2p + q = 10         --------------------(II)

Substitute p = 11 -2q in equation (II)

2(11 - 2q) + q =10

2*11 - 2q *2 + q = 10

22 - 4q + q = 10

  22 - 3q    = 10

         -3q   = 10 - 22

        -3q    = -12

              q = -12/-3

 q = 4

Plugin q = 4 in equation (I)

p + 2q = 11

p + 2*4  = 11

p + 8 = 11

      p = 11 - 8

      p = 3

Answer:

One, or both the congruent angles measure 30 degrees

Step-by-step explanation:

180 - 120 = 60

60 / 2 = 30

30 + 30 + 120 = 180

Yes

Answer:

30°

Step-by-step explanation:

180-120=60

60/2 = 30

Answer:

-3

Step-by-step explanation:

The equation would first look like 9/-3

When you are dividing negativ numbers a negative divided by a positive is always a negative so 9/-3 is -3

Answer:

the answer is the first one which is a

Answer:

A

Step-by-step explanation:

Distributive property is the stuff you do in the parentheses. Here's an example-

6(x+1)=13

6 times x would be 6x and 6 times 1 would be one

6x+1=13

Separate the x

6x+1=13

    -1    -1

6x=12

Divide

x=2

Answer:

children is 115 and adult is 117

Step-by-step explanation:

Given

let the number of children be x

and the number of adults be y

so

x+y=232----------------1

We are told that the  daily prices are $1.50 for children and $2.25 for adults

so

1.5x+2.25y= 435.75-------------------2

Hence the system of equation for the situation is

x+y=232-----1

1.5x+2.25y= 435.75-------2

From 1    x=232-y

Put this in Eqn 2

1.5(232-y)+2.25y= 435.75

348-1.5y+2.25y= 435.75

collect like terms

-1.5y+2.25y= 435.75-348

0.75y=87.75

divide both sides by 0.75

y= 87.75/0.75

y=117

the number of adults is 117

put y= 117 in eqn 1

x+117=232

x=232-117

x=115

The number of children is 115

Answer:

Simplifying

7 + -1(4p + 3) = -3(p + 2) + -1(2P + 3)

Reorder the terms:

7 + -1(3 + 4p) = -3(p + 2) + -1(2P + 3)

7 + (3 * -1 + 4p * -1) = -3(p + 2) + -1(2P + 3)

7 + (-3 + -4p) = -3(p + 2) + -1(2P + 3)

Combine like terms: 7 + -3 = 4

4 + -4p = -3(p + 2) + -1(2P + 3)

Reorder the terms:

4 + -4p = -3(2 + p) + -1(2P + 3)

4 + -4p = (2 * -3 + p * -3) + -1(2P + 3)

4 + -4p = (-6 + -3p) + -1(2P + 3)

Reorder the terms:

4 + -4p = -6 + -3p + -1(3 + 2P)

4 + -4p = -6 + -3p + (3 * -1 + 2P * -1)

4 + -4p = -6 + -3p + (-3 + -2P)

Reorder the terms:

4 + -4p = -6 + -3 + -2P + -3p

Combine like terms: -6 + -3 = -9

4 + -4p = -9 + -2P + -3p

Solving

4 + -4p = -9 + -2P + -3p

Solving for variable 'p'.

Move all terms containing p to the left, all other terms to the right.

Add '3p' to each side of the equation.

4 + -4p + 3p = -9 + -2P + -3p + 3p

Combine like terms: -4p + 3p = -1p

4 + -1p = -9 + -2P + -3p + 3p

Combine like terms: -3p + 3p = 0

4 + -1p = -9 + -2P + 0

4 + -1p = -9 + -2P

Add '-4' to each side of the equation.

4 + -4 + -1p = -9 + -4 + -2P

Combine like terms: 4 + -4 = 0

0 + -1p = -9 + -4 + -2P

-1p = -9 + -4 + -2P

Combine like terms: -9 + -4 = -13

-1p = -13 + -2P

Divide each side by '-1'.

p = 13 + 2P

Simplifying

p = 13 + 2P

As given

x²-3x-10

Now according to the one of the rule of factorization ,

we have to find such two values whose product becomes equal to the

"product of first and last term " and if we sum those numbers it should be equal to the "middle term of it".

so such numbers are   -5x and +2x

if we add or multiply them we get the above

as  adding    -5x+2x=-3x  (middle term)

also multiplying   -5x*2x=-10x²  (product of 1st and last term)

so now , we can write as,

x²-3x-10

=x²-5x+2x-10

now making groups of 2 terms,

=(x²-5x)+(2x-10)

now common

=x(x-5)+2(x-5)

now common(x-5)

=(x-5)(x+2)   This is the required factors.....

Answer:

90 cm²

Step-by-step explanation:

Given that both triangles are similar, it follows that the ratio of their area equals the square of their corresponding sides.

Let the area of the other triangle be x. Therefore:

[tex] \frac{10}{x} = \frac{4^2}{12^2} [/tex]

[tex] \frac{10}{x} = \frac{16}{144} [/tex]

Cross multiply

[tex] 10*144 = 16*x [/tex]

[tex] 1440 = 16x [/tex]

Divide both sides by 16

90 = x

Area of the other polygon = 90 cm²

Answer:

Answer is 90

I had this homework and got it right

===========================================================

Explanation:

The question asks "What percent of females participate in extracurricular activities?" This means we only focus on the second column. There are 36 women, and of this total, 19 are in extracurricular activities.

Dividing the two values leads to approximately 19/36 = 0.52777 which rounds to 0.53

Then we move the decimal to the right two spots to get 53%

Roughly 53% of the female students participate in extracurricular activities.

We are given here the individual costs of DVD and CD as well as the total sales and the number of items sold on one day. To solve the number of DVDs and CDs sold each, we devise two independent linear equations:

(1) x + y = 39

(2) 4x + 7y = 204

x- number of DVDs; y - number of CDs

solving, x= 23 DVDs

Answer:

8100

Step-by-step explanation:

We first see that in the first day it tripled from 100 to 300 this is the pattern that is seen throughout this whole experemint, we can see that the cells triple again on the second day to get 900 cells from this. It is likely to say that they will triple again on the third day to get 2100 and again on the fourth to get 8100

Answer:

Step-by-step explanation:

x2 + 5x + 4  (the area of the rectangle)

x + 2   (the length of one side)

(x2 + 5x + 4)/(x + 2)

do a division of this polynomial and you get;    (x + 3) - 2/(x+2), you could leave the answer like this or you could simplify by using the LCM method

= [(x+2)(x+3) - 2]/(x + 2)

checking; (x + 2)*[(x+2)(x+3) - 2]/(x + 2) = (x+2)(x+3) - 2 = x2 +5x + 6 - 2 = x2 +5x + 4 (proven)

This expression is simplified by adding the two terms together since they are like terms.

6f + 8f  = 14f

Therefore, the simplified expression is 14f.

Answer:

Option C

Step-by-step explanation:

To test a graph whether it represents a function or relation we conduct a vertical line graph.

If the vertical line intersect the graph at two different points, graph represents a relation only.

By analyzing the given graph with the vertical line test,

Since, a vertical line (x = -4) intersect the graph at two points (y = -1 and y = 5),

Given graph represents a relation only.

Option C is the answer.

Answer:

a=1/3

Step-by-step explanation:

from the point on the graph

x=4 and y=8

substitute them into the equation:

y=a(x-2) (2x+4)

you will get

8=a(4-2) (2(4)+4)

8=a(2) (8+4)

8=a(2) (12)

8=2a×12

8=24a

divide both sides by 24

8/24=24a/24

1/3=a or a=1/3

Step-by-step explanation:

Answer:

2/7 , 3/7 , 6/7

Step-by-step explanation:

Answer:

x=1 and y = 5

Step-by-step explanation:

you add y = 4x+1 into the equation

3x+2(4x+1)=13

3x + 8x + 2 = 13

11x = 11

x = 1

then you just add the x into the equation y = 4x+1

4(1)+1

y = 5
