Step-by-step explanation:

Answer 2

Answer: x = 2

Step-by-step explanation:  - 4/5*9x +4/5*20 - 3x= 4/5x- 6

-36/5*x+16-3x-4/5*x= -6

-36/5*x-15x/5-4/5*x=-6-16

-55/5*x=-22

-11x= -22

x= -22:(-11)

explain the difference between an Expression and an Equation.

Answers

Answer:

An equation has a set value or a mathematical sentence that contains an = sign. An expression is a math sentence that contains numbers, letters, and symbols( not an = tho) and the value of the variable can change.Equations and expressions are often encountered when understanding mathematical concepts. If compared with language, expressions are like phrases while equations are complete sentences. Expressions have no relations whereas equations reveal relationships. You need to solve equations while expressions can only be evaluated.

Step-by-step explanation:

The difference between the expression and an equation is explained below:

Difference between the equation and expression:

The equation represents the mathematical value while the expression could include the numbers, letters, etc. The expression should be treated as phrases while the equations are considered to be complete sentences. The expression does not show any kind of relations while the equation should show the relationship.

In this way, it should be differentiated.

if m<2=98, m<3=23 and m<8=70, find each measure

Answers

Answer:

Step-by-step explanation:

From the picture attached,

There are two parallel lines intersected by three transverse lines.

m∠2 = 98°, m∠3 = 23°, m∠8 = 70°

a). Since ∠1 and ∠2 are linear pairs,

   m∠1 + m∠2 = 180°

   m∠1 + 98° = 180°

   m∠1 = 180 - 98

   m∠1 = 82°

b). m∠4 = m∠7 [Corresponding angles]

   m∠7 = 180° - (m∠2 + m∠3) [Property of a triangle]

            = 180 - (98 + 23)

            = 180 - 121

            = 59°

    m∠4 = m∠7 = 59°

c). m∠5 = 180° - (m∠3 + m∠4)

             = 180° - (23° + 59°)

             = 180° - 82°

             = 98°

d). m∠6 = 180° - (m∠7 + m∠8)

             = 180° - (59° + 70°)

             = 180 - 129

             = 51°

e). m∠7 = 59° [Calculated in part b]

f). m∠9 = 180° - (m∠4 + m∠8) [Property of a triangle]

            = 180° - (59 + 70)°

            = 180 - 129

            = 51°

g). m∠10 = 180° - m∠9

               = 180 - 51

               = 129°

Jorge’s printer can print 36 pages in 18 minutes. How many pages can it print in 1 hour

Answers

Answer:

120 pages can be printed in 1 hour.

Step-by-step explanation:

First divide 36 by 18 to figure out how many pages can be printed in a minute.

Like this: 36 pages ÷ 18 minutes = 2 pages in one minute.

Now, multiply 2 by 60 to figure out how many pages can be printed out in a hour.

Like this: 2 pages in one minute × 60 minutes ( one hour) = 120 pages in one hour can be printed.

An electric company calculates a persons monthly bill from the number of kilowatt kWh, x, used

The function (in photo ) determines the bill

How much is the bill for a person who uses 400 kWh in a month

A. 50
B. 60
C. 40
D. 30

Answers

Answer:

Option (A)

Step-by-step explanation:

From the given piecewise function that represent the amount of bill from number of units of electricity used is 'x' kWh.

b(x) = 0.10x   when x ≤ 200

         0.15(x - 200) + 20  when x > 200

For x = 400 kWh,

Function which represents the expenses of the bill,

b(400) = 0.15(400 - 200) + 20 [Since x > 200]

           = 0.15(200) + 20

           = 30 + 20

           = $50

Therefore, Option (A) will be the answer.

Delia went to the market to buy 4.5 pounds of sliced fruit in a container.she paid with a 20 bill and a 5 bill and received 3.67 as change.what was the cost for one pound of sliced fruit before taxes

Answers

Answer:

One pound of the item will cost 4.74 bill

Step-by-step explanation:

In this problem, we are told that Delia bought 4.5 pounds of fruit

and paid with a toa total bill of 20+5= 25 bill

and also she received a  change of 3.67

this means that the item she bought cost 25-3.67= 21.33bill

now if 4.5 pounds of items cost 21.33 bill

then 1 pound will cost Xbill

cross multiply and solve for Xbill

X= 21.33/4.5

X= 4.74 bill

One pound of the item will cost 4.74 bill

A music festival offers one-day and three-day passes. A one day pass costs $100 and a three-day pass costs $250. write an expression for the total ticket sales if (n) one day passes and (t) three day passes are sold.

Answers

Answer:

100n+250t

Step-by-step explanation:

cost of the1 one day pass=100

cost of n one day passes=100n

cost of the 1 three day pass=250

cost of t three day passes=250t

Total sale= 100n+250t

The expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.

What is an expression?

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now it is given that,

Cost of one-day passes, n = $100

Cost of three-day passes, t = $250

So, Total tickets sold = Cost of one-day passes + Cost of three-day passes

Total tickets sold = n + t

⇒ n + t = $100 + $250

⇒ n + t = $350

which is the required expression for total tickets sold.

Thus, the expression for the total ticket sales if (n) one day passes and (t) three day passes are sold is n + t = $350.
