Which statement must be true.

Answers

A is the correct statement

10 + 2x – 4 = 2x + 1 + x ?

Answers

Answer:

x = 5

Step-by-step explanation:

10 + 2x - 4 = 2x + 1 + x

First, we can subtract 2x from both sides:

10 - 4 = 1 + x

We can simplify 10-4 to 6:

6 = 1 + x

Now, we can subtract 1 from both sides:

5 = x

x = 5

Answer:

x=5

Step-by-step explanation:

10+2x=4=2x+1+x (Then subtract 2x from both sides)

    -2x.    -2x

10-4=1+x (Simplify)

1+x=10-4 (Switch sides)

1+x=6 (Then subtract the numbers: 10-4=6)

1+x=6 (Subtract 1 from both sides)

-1    -1

x=5

Farmer John walks his pet pig around his barn every day. The barn is 25
meters by 12 meters. If we walks the pig around the barn three times, how
many meters did farmer John and his plg walk?

Answers

Answer:

900m

Step-by-step explanation:

A=wl

W=25

L=12

A=25 x 12

A= 300

300 meters x 3 laps = 900 meters walked

Farmer John and his pig walks 222 meters distance if he walks the pig around the barn three times.

What is rectangle?

A rectangle is a part of a quadrilateral, whose sides are parallel to each other and equal.

Give that,

The length of Barn = 25 meters.

And width of Barn = 12 meters.

The perimeter of barn = 2 (12 + 25) = 2 x 37 = 74 meters.

Since, farmer walks the pig around the barn 3 times,

So the total distance covered by farmer John and his pig

= 3 x perimeter of barn

= 3 x 74

= 222 meters.

Hence, farmer and his dong covers 222 meters distance.

one number is 2 less than a second number. twice the second number is 22 more than 5 times the first

Answers

Answer:

The first number is -6. The second number is -4.

Step-by-step explanation:

Let the second number be x.

"one number is 2 less than a second number"

Second number: x

First number: x - 2

"twice the second number is 22 more than 5 times the first"

2x = 5(x - 2) + 22

Distribute on the right side.

2x = 5x - 10 + 22

Subtract 5x from both sides. Combine like terms on the right side.

-3x = 12

Divide both sides by -3.

x = -4

x - 2 = -4 - 2 = -6

The first number is -6. The second number is -4.

Answer:

TWO PARALLEL LINES AND LINES WITH EQUAL LENGTHS

Step-by-step explanation:

As we all know a quadrilateral is a polygon with four sides(edges and corners). Trapezoid is a four-sided shape with opposite sides parallel while parallelogram is also a for sided shape that has its opposite sides paralleled.

NOW, a quadrilateral is said to be both a trapezoid and a parallelogram when there are two opposite parallel lines, which are lines with equal lengths.

Step-by-step explanation:

[tex]ax+b=12.5\\\\ax+b-b=12.5-b\\\\ax=12.5-b\\\\\frac{1}{a}*ax =\frac{1}{a}*(12.5-b)\\\\x=\frac{12.5-b}{a}[/tex]

The value of x is x=(12.5-b)/a

What is equation?

An equation in math is an equality relationship between two expressions written on both sides of the equal to sign.

For example, 3y = 16 is an equation.

Given equation:

ax+b=12.5

DS=3x+10 and SE=6x-2. What is the value of DE?

Answers

Answer:

9x+8

Step-by-step explanation:

Given DS = 3x+10 and SE = 6x-2_ the value of DE is expressed as shown;

DE = DS+SE

Substitute the given functions into the formula to get DE

DE = (3x+10)+(6x-2)

Open the parentheses

DE = 3x+10+6x-2

Collect the like terms

DE = 3x+6x+10-2

DE = 9x+8

Hence the value of DE is 9x+8

How many minutes are there in 2.35 years?

Everyone knows that there are 24 hours in a day and 60 minutes in an hour. So you do 24 x 60 which is 1440. And then do 365 x 1440 ( because there is 365 days in a year) which is 525600 and then you multiply that by 2.35. Your final answer is 1235160.


a. Write an expression that represents the total cost of large pizza. let t = # of toppings.

b. Brust orders an “everything” pizza with 8 toppings. use your expression to find the total cost of the pizza.

c. Kelly and Bean show up and order 4 identical pizzas. write an expression that represents the total cost for the 4 pizzas. (each pizza would have the same # of toppings.)

d. Kelly and Bean order sardines and pineapple on the 4 pizzas. use your expression from (c) to find the total cost of the 4 pizzas.

Answers

Answer:

a). Total cost of one pizza = 14.99 + 1.99t

b). $30.91

c). Cost of 4 pizza = 59.96 + 7.96t

d). Total cost of 4 pizza with 2 toppings = $75.88

Step-by-step explanation:

a). Cost of the large pizza = $14.99

    Each topping of the pizza is $1.99 extra.

    If total number of layers of the toppings = t

    Total cost of one pizza = 14.99 + 1.99t

b). Brust orders a pizza with number of toppings = 8

    From the given expression,

    Total cost of pizza = 14.99 + 1.99(8)

                                    = 14.99 + 15.92

                                    = $30.91

c). Kelly and Bean ordered number of identical pizzas = 4  

   Expression that represents the cost of 4 pizzas = 4(14.99 + 1.99t)

                                                                                   = 59.96 + 7.96t

d). Kelly and Bean order 4 pizzas with sardines and pineapple. That means 2 toppings on one pizza.

   Cost of 4 pizza with toppings = 59.96 + 7.96×2

                                                     = $75.88

Add up the X’s: 3x - 4 = 8

Isolate the X’s, Transfer -4 to the other side of the equal sign, while also flipping the sign (negative & positive): 3x = 8 + 4

Add up the 8 & 4: 3x = 12

Divide each side by 3: 3x/3 = 12/3
