2x +4 (3 - 2x) = 3(2x + 2)/6 + 4

Answer:

Sadie weighs 61 pounds.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

Sadie's weight is x.

Buddy's weight is y.

Buddy weighs 14 pounds more than Sadie.

This means that [tex]y = x + 14[/tex]

Their total weight is 136 pounds.

This means that

[tex]x + y = 136[/tex]

Since [tex]y = x + 14[/tex]

[tex]x + x + 14 = 136[/tex]

[tex]2x = 122[/tex]

[tex]x = \frac{122}{2}[/tex]

[tex]x = 61[/tex]

Sadie weighs 61 pounds.

Answer:

1/10

Step-by-step explanation:

1/10 + 1/10 + 1/10 + 1/10 + 1/10 = 1/2

Answer:

The first book was published in 1816.

Step-by-step explanation:

A series of books is published at 4-year intervals.

This means that:

The first book is published at year x.

The second book is published at year x + 4.

The third book is published at year x + 4 + 4 = x + 8

The fourth book is published at year x + 8 + 4 = x + 12

The fifth book is published at year x + 12 + 4 = x + 16

When the fifth book is issued, the sum of the publication’s years will be 10,020.

This means that:

[tex]x + x + 4 + x + 8 + x + 12 + x + 16 = 10020[/tex]

[tex]5x + 40 = 10020[/tex]

When was the first books published?

This is x. So

[tex]5x + 40 = 10020[/tex]

[tex]5x = 9080[/tex]

[tex]x = \frac{9080}{5}[/tex]

[tex]x = 1816[/tex]

The first book was published in 1816.

Answer:

C: 8

Step-by-step explanation:

Answer:

A polynomial function f of least degree  = f = x³ - 7x² + 36

The function in standard form = f = x³ - 7x² + 36

Step-by-step explanation:

As given, Leading coefficient of polynomial function = 1

Also given, zeroes of the function = -2, 3, 6

for root -2 : (x - (-2)) = (x + 2)

for root 3 : ( x - 3)

for root 6 : (x - 6)

Therefore, the polynomial function becomes -

f = 1(x+2)(x-3)(x-6)

⇒f = (x+2)(x² - 6x - 3x + 18)

⇒f = (x+2)(x² - 9x + 18)

⇒f = x³ - 9x² + 18x + 2x² - 18x + 36

⇒f = x³ - 7x² + 36

The polynomial function in standard form is [tex]f(x) = x^3 - 8x^2 +9x +18[/tex]

The zeros of the polynomial are given as:

[tex]Zeroes = -2,3,6[/tex]

Rewrite as:

[tex]x= -2,3,6[/tex]

Express the zeroes as an equation

[tex]x= -2[/tex],  [tex]x =3[/tex] and [tex]x =6[/tex]

Equate to 0

[tex]x + 2 = 0[/tex], [tex]x -3 = 0[/tex] and [tex]x -6 = 0[/tex]

Multiply the equations

[tex](x + 1) \times (x - 3) \times (x - 6) = 0 \times 0 \times 0[/tex]

[tex](x + 1) \times (x - 3) \times (x - 6) = 0[/tex]

Expand

[tex](x^2 - 3x + x - 3) \times (x - 6) = 0[/tex]

[tex](x^2 - 2x - 3) \times (x - 6) = 0[/tex]

Expand

[tex]x^3 - 2x^2 - 3x -6x^2 +12x +18 = 0[/tex]

Collect like terms

[tex]x^3 - 2x^2 -6x^2 - 3x +12x +18 = 0[/tex]

[tex]x^3 - 8x^2 +9x +18 = 0[/tex]

Express as a function

[tex]f(x) = x^3 - 8x^2 +9x +18[/tex]

Hence, the function in standard form is [tex]f(x) = x^3 - 8x^2 +9x +18[/tex]

Answer:

  1/8

Step-by-step explanation:

You can replace % with /100 to make it a fraction.

  12 1/2% = (12 1/2)/100 = (25/2)/100 = 25/200 = 1/8

Or, you can reduce the decimal fraction.

Answer: y = -2/5x + 4

Steps:

First find the slope of the equation y=mx+b.

slope equation (m=y2-y1/x2-x1)

Then plug in your coordinates, which the first set is (5,2) and the second set if (-5,6). m = 6 - 2/ -5 - 5

Which your answer will be 4/-10, simplify it by dividing both by 2 to get -2/5 for your slope.

Next, find your y-intercept (b).

substitute the first set of coordinates into the equation y=mx+b

Substitute: 2 = -2/5 (5) +b

Then multiply -2/5 with 5 to get (-2). Your equation should now reduce to be

2 = -2 +b

Do inverse operations on both sides by adding 2 to each side (the 2 side and the -2+b side).

This gets rid of the -2 and since we added 2 to both sides, your final equation should look like 4 = b for your y-intercept.

Plug in everything to get y = -2/5x + 4

Answer:

x= -4

Step-by-step explanation:

Answer: x = -4

Step-by-step explanation:

first, we remove the parentheses.

3x - 12 + 2x = 7x + 10 + 2x - 6

then, we cancel equal terms.

3x - 12 = 7x + 10 - 6

then, we calculate.

3x - 12 = 7x + 4

next, we move the terms.

3x - 7x = 4 + 12

then, we collect like terms and calculate.

-4x = 16

finally, we divide both sides.

x = -4

Answer:

a.(2 × 25) + 105

Step-by-step explanation:

Let the number of hours spent repairing the bike = x

Mr. Jones charged Roberta $105 for parts and $25 per hour for labor to repair her bicycle.

Therefore, our algebraic expression

= $25× x + $105

= 25x + 105

We were told in the question that He spent 2 hours repairing her bike.

Hence:

25 × 2 + 105

Therefore, the correct option is option a

a.(2 × 25) + 105

Answer:

Red grapes.

Step-by-step explanation:

If you find how much one bag of each grape cost which is:

$13.00 ÷ 5 = 2.60 (1 bag of red grapes)

$5.08 ÷ 2 = $2.54 (1 bag of green grapes)

See the price and you'll know it is red grapes.

Answer:

Streamers cost 2.50 and balloons cost 1.25.

Step-by-step explanation:

Pls mark brainliest.

Answer:

Balloon : $1.25

Streamer : $ 2.50

Step-by-step explanation:

Form simultaneous equations.

Let streamer be represented by ------------s

Let balloons be represented by ------------b

So the equations will be;

3s + 2b = 10 ----------------i

2s + 1b = 6.25---------------ii

Make the terms with s equal by multiplication

[3s + 2b = 10 ]2

[2s + 1b = 6.25]3

Perform subtraction

6s + 4b = 20

6s + 3b = 18.75

b = 1.25 ---------iii

Use  iii  in ii  as;

2s + 1b = 6.25

2s + 1.25 = 6.25

2s = 6.25 - 1.25

2s = 5.00

s= 5.00 / 2

s= 2.5

Hence ; a balloon is  $1.25   and a streamer is $2.5

Answer:

If m is the midpoint of ab it means am is equal to mb

am = 3x + 8 and mb = 6x-4

and ab  = am + mb

first find the value of x by using am = mb

3x + 8 = 6x - 4

8 + 4 = 6x - 3x

12 = 3x

x = 4

ab = 3 (4) + 8

= 12 + 8 = 20 = mb

ab = am + mb

= 20 + 20

40

so, the value of ab is 40
