Answer:

11

Step-by-step explanation:

11 fred

6 louis

18 tom

please mark me as brainliest!!<3

Answer:

Fred Painted 11 chairs. B

Step-by-step explanation:

Let Tom = T

Let Louis = L

Let Fred = F

Formulas

T = 3*L

F = L + 5

T + L + F = 35             Subtitute for Fred and Tom

Solution

3*L + L + L+5 = 35      Combine like terms

5L + 5 = 35                 Subtract 3 from both sides

5L = 35 - 5

5L = 30                       Divide by 5

L = 30/5  

L = 6

Fred Painted 5 more than Louis.

That makes Fred = 11

Answer:

25

Step-by-step explanation:

Answer:

3/4 * 2/5

Step-by-step explanation:

Areas is L * W

(1/5 + 1/5) * (1/4 + 1/4 + 1/4) = 2/5 * 3/4

Answer:

3/10

Step-by-step explanation:

The area will be the length of the striped rectangle multiplied by the width of the striped rectangle.

The length will be 1/4 + 1/4 + 1/4 = 3/4 and the width will be 1/5 + 1/5 = 2/5.

Now just multiply 3/4 by 2/5 and you'll get 6/20 which in its simplest form is 3/10.

Step-by-step explanation:

Step 1: Define Systems

5x - 9y = -26

-2x + 3y = 11

Step 2: Rewrite Systems

-2x + 3y = 11

Step 3: Redefine Systems

5x - 9y = -26

-6x + 9y = 33

Step 4: Solve for x

Elimination

Step 5: Solve for y

Answer:

x= -7

y= -1

Step-by-step explanation:

5x-9y= -26..............(1)

-2x+3y= 11...............(2)

5(-2x+3y= 11)

-10x +15y = 55................(3)

2(5x-9y= -26)

10x-18y= -52.....................(4)

Add equation 3&4

-10x+15y= 55

10-18y= -52

-3y= 3

y= -1

put y= -1 into equation ............(3)

-10x+15y= 55

-10x+15(-1)= 55

-10x-15 = 55

-10x= 55+15

-10x= 70

x= -7

Therefore;

x= - 7 and y= - 1

Answer:

Below.

Step-by-step explanation:

30 kg 500g + 28kg 700g

= 58kg + 1200g

= 59kg 200g.

Difference

= 30 kg 500g - 28kg 700g

= 2kg + 500 - 700

= 2kg - 200g

= 1kg 800g.

Answer:

x<56

Step-by-step explanation:

Since the dot over 56 isn't filled in, the inequality doesn't include 56 (so we'll use < or > not [tex]\leq[/tex] or [tex]\geq[/tex])

Now, let's look at the direction of the shading: is it going to the left of 56 or to the right?

This shading is to the left of 56, which indicates that it's all of the numbers less than 56.

As said above, the inequality doesn't include 56

therefore, it will be x<56 (x is less than 56, and 56 is not included)

hope this helps!

Answer:

x<56

Step-by-step explanation:

First off look at the number the dot is on.

Its at 56.

So next we see if the dot is filled in or not.

If the dot is filled in, then its either less than equal to or greater than equal to

If the dot is empty, then its less than or greater than

The dot is not filled in

So next see which way the line is going

The line is going left, which means that the number is getting smaller

Make the equation

start with x

x

The sign will be < because x has to be less than 56.

x < 56

An easy trick to remember which way the sign goes in these types of questions [not in all cases though] is look which way the line is going.

Think of the signs as arrows

If you have < then the line goes <-- left

If you have > then the line goes --> right

Step-by-step explanation:

Step-by-step explanation:

We have v = u + at = (21) + (12)(2) = 45.

Answer:

v= 1008

v=21*2*12*2

Step-by-step explanation:

Answer:

Please check the explanation.

Step-by-step explanation:

Part a)

Given

It is clear that m∠ABD and m∠CBD lie on a straight line.

Thus, the sum of m∠ABD and m∠CBD will be 180°.

Hence,

m∠ABD and m∠CBD are supplementary angles.

Part b)

As m∠ABD and m∠CBD are supplementary angles, so the sum of m∠ABD and m∠CBD will be 180°.

Thus,

m∠ABD + m∠CBD = 180°

substitute m∠ABD = (7q-46)° and m∠CBD = (3q + 6)°

(7q-46)° + (3q + 6)° =  180°

Part c)

Given the equation

(7q-46)° + (3q + 6)° =  180°

Combining the like terms

7q + 3q - 46 + 6 = 180

10q - 40 = 180

10q = 180 + 40

10q = 220

divide both sides by 10

10q/10 = 220/10

q = 22

Therefore, the value of q = 22

Part d)

As

m∠ABD = (7q-46)°

substituting q = 22

m∠ABD = 7(22) - 46

             = 154 - 46

             = 108°

also

m∠CBD = (3q + 6)°

substituting q = 22

m∠CBD = 3(22) + 6

              = 66+6

              = 72°

Therefore,

Answer:

3/6 of a minute

Step-by-step explanation:

3/6 can also be simplified to 1/2. So, 1/2 of a minute is 30 seconds. 2/6 can be simplified to 1/3. So, 1/3 of an hour is 20 minutes. 30 seconds is very much shorter than 20 minutes. Thus, 3/6 of a minute is shorter than 2/6 fo an hour.

Answer:

5/8 i TOOK THE EXAM REVIEW

Step-by-step explanation:

Answer:

  (a)  m = 10

  (b)  n = 160

Step-by-step explanation:

To rewrite the expression in the manner indicated, write an equation that sets the given expression equal to the desired expression. Then solve for the variable value. The distributive property and the usual rules of exponents apply.

The rules of exponents you can use here are ...

  (a^b)(a^c) = a^(b+c)

  (a^b)^c = a^(bc)

  a^0 = 1

__

(a) 2^101 +2^103 = m×2^100

  2^(101-100) +2^(103-100) = m × 2^(100-100) . . . . . . . multiply by 2^(-100)

  2^1 +2^3 = m

  2 + 8 = m

  m = 10

__

(b) 2^101 +2^103 = n×4^48

  2^101 +2^103 = n×(2^2)^48 . . . . . substitute 4 = 2^2

  2^101 +2^103 = n×2^96 . . . . . . . . simplify

  2^5 +2^7 = n . . . . . . . . . . . . . . . . . as above, multiply by 2^(-96)

  32 +128 = n

  n = 160

_____

Additional comment

The rules of exponents tell you that ...

  (m × 2^100) × 2^-100 = m × 2^(100 -100) = m × 2^0 = m

This is effectively the same as dividing by 2^100. You're doing the same thing you would do to solve any linear equation: divide by the coefficient of the variable.

Answer:

senior citizen cost $4

children cost $7

Step-by-step explanation:

The question is not complete

Brenda's school is selling tickets to a spring musical. On the first day of ticket sales the school sold 3 senior citizen tickets and 9 child ... The school took in $67.00 on the second day by selling 8 senior citizen tickets and 5 child tickets. What is the price each of one senior citizen ticket and one child ticket?

Given data

let senior citizens be x

and children be y

so

3x+9y= 75--------------1

on the second day

8x+5y= 67------------2

solve 1 and 2 above

3x+9y= 75     X8

8x+5y= 67      X3

 24x+72y=600

-24x+15y=201

   0x+57y= 399

divide both sides by 57

y= 399/57

y= $7

put y= 7 in eqn 1 above

3x+9*7= 75

3x+63= 75

3x=75-63

3x=12

x= 12/3

x= $4

Answer:

Step-by-step explanation:

what number is 26% of 50 is the question

you can set up a proportion:   is  =   percent

                                                  of           100

what number 'is' = you are looking for this, so assign a variable

'of = 50

26% =  26  

            100

n  = 26      You can cross-multiply to find 'n'

50     100

100n = 1300

n = 13
