A wire is (7x – 3) meters long. A length of (3x – 4) meters is cut for use(a) How much wire is left?

Answers

Answer 1

Answer:

The amount of wire left is 4x + 1

Step-by-step explanation:

Initially, the wire is (7x - 3) meters long.

A length of (3x - 4) meters is cut.

How much wire is left?

Initial amount subtracted by the amount that is cut. So

(7x - 3) - (3x - 4) = 7x - 3 - 3x + 4

We combine the like terms

7x - 3x - 3 + 4 = 4x + 1

The amount of wire left is 4x + 1

Mary, Peter, and Lucy were picking chestnuts. Mary picked twice as much chestnuts than Peter. Lucy picked 2 kg more than Peter. Together the three of them picked 26 kg of chestnuts. How many kilograms did each of them pick?

Answers

Answer and Step-by-step explanation: Let \displaystyle xx be the amount Peter picked. Then Mary and Lucy picked \displaystyle 2x2x and \displaystyle x+2x+2, respectively. So

\displaystyle x+2x+x+2=26x+2x+x+2=26

\displaystyle 4x=244x=24

\displaystyle x=6x=6

Therefore, Peter, Mary, and Lucy picked 6, 12, and 8 kg, respectively.

Peter picked 6 kilograms of chestnuts.

Mary picked 12 kilograms of chestnuts.

Lucy picked 8 kilograms of chestnuts.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Let Peter pick x kilograms of chestnuts.

Given that Mary picked twice as many chestnuts as Peter

So, Mary picks 2x kilograms of chestnuts.

And Lucy picks  x + 2 kilograms of chestnuts

Together the three of them picked 26 kg of chestnuts

So, x + 2x + x + 2 = 26

4x + 2= 26

4x= 26-2

4x= 24

4x/4= 24/4

x= 6

Thus, Peter picked 6 kilograms of chestnuts.

⇒ 2x

⇒ 2 (6)

⇒ 12

Thus, Mary picked 12 kilograms of chestnuts.

⇒ x + 2

⇒ 6 + 2

⇒ 8

Thus, Lucy picked 8 kilograms of chestnuts.

Answers

Answer:

c = 20

Step-by-step explanation:

Given that,

A rectangle PQRS,

QT = c and ST = 4c-60

We need to find the value of c.

We know that the diagonals of a rectangle bisect each other such that,

QT = ST

Putting values,

c = 4c - 60

Taking like terms together,

60 = 4c - c

60 = 3c

c = 20

Hence, the value of c is 20.

solve using the order of operations 5 x (2+4) -52

Answers

Answer:

-22

Step-by-step explanation:

Order of Operations:

Parenthesis

Exponents

Multiplication and Division

Addition and Subtraction

First, you need to do parenthesis first so inside the parenthesis is 2+4 which is 6

Now the equation looks like this:

5 x 6-52

Since there are no exponents we can skip that step, next is multiplication so 5 x 6 is 30 so the equation now looks like this:

30-52

Subtract and you will have

-22

Brenda collected this data from an experiment.
Hours of Sunlight (t) 3 5 7 9 11 13
Height in inches (h) 2.3 3.3 3.9 6.1 7.0 8.4
For the line of fit h = 0.6t + 0.44, what is the residual (difference) of the data point at ???? = 7?

Answers

Given:

The data table of an experiment.

Equation of best fit line is

[tex]h=0.6t+0.44[/tex]

To find:

The residual (difference) of the data point at t = 7.

Solution:

From the given table, it is clear that the value of h is 3.9 at t =7.

So, observed value is 3.9.

Equation of best fit line is

[tex]h=0.6t+0.44[/tex]

Putting t = 7, we get

[tex]h=0.6(7)+0.44[/tex]

[tex]h=4.2+0.44[/tex]

[tex]h=4.64[/tex]

So, the estimated value is 4.64.

Residual formula:

Residual = Observed value - Estimated value

              = [tex]3.9-4.64[/tex]

              = [tex]-0.74[/tex]

Therefore, the residual value of the data point at t = 7 is -0.74.
