Answer:

x = 7 units

Step-by-step explanation:

Left area = (3x-1)(4)

Right area = 8*12  - (4 (  x -3))     and the areas are =

(3x-1)4 = 8*12 - ( 4(x-3))    expand both sides

12x - 4  = 96 - 4x + 12       solve for x = 7 units

Answer:

Area of big rectangle: 8 x 12 =96

Area of white part : 4(x-3)

96-(4(x-3))

96-(4x-12)

96-4x+12

Area of rectangular grey part: 108-4x

Area of other grey figure:

4(3x-1)

= 12x- 4

Finding x:

12x-4 = 108 -4x

-4-108 = -4x - 12x

112 = 16x

x= 7

The lowest score that Keiko is trying to score to get in the "ryo" range is , the inequality to represent this story is (x+85+57+78)/4 > 70  .

In the question ,

it is given that

Keiko need to score average above 70 to get in the ryo range

let x be the marks that Keiko scores in the next test ,

so, the average = (x+85+57+78)/4

According to the question

Average > 70

Substituting the value of average , the inequality becomes

(x+85+57+78)/4 > 70

x+85+57+78 > 280

x+220 > 280

x > 280-220

x > 60

the lowest score that Keiko should get is greater than 60 .

When the inequality x > 60 , will be graphed then the limit will be an open circle as equal to sign is not included in the inequality .

as when the numbers increases , it move towards right side

So, When the inequality is graphed, the line will have an arrow pointing towards the right .

Therefore , the lowest score that Keiko is trying to score to get in the "ryo" range is , the inequality to represent this story is  greater than 60 ,

the inequality to represent this story is (x+85+57+78)/4 > 70 ,

the limit of graph will be open circle and arrow will be pointing towards right .

Answer: 2

Step-by-step explanation:

The greatest divisor of 8 that is less than 18 is 16, and 16 divided by 8 is 2.

The next digit of quotient is 16.

Here given that,

4184 is divisible by 8

since we know that,

Division is a process of repeated subtraction. It is the inverse action of multiplication. It is characterised as the formation of equal groupings. When we divide numbers, we split them down into smaller amounts so that the multiplication of those smaller numbers equals the larger number taken.

4184 is divisible by 8 we get,

⇒ 4148/8

⇒ 516

So, the quotient is 516

Hence,

Answer:

The answer is 3, but here’s how I got that answer.

Step-by-step explanation:

As we know the trifle recipe requires 1 ½ cups of sugar, and the chocolate cake requires double the amount of sugar.

You have two options.

Multiply 1½ by 2

1½ x 2 = 3

———————————

Or add 1½ + 1½

1½ + 1½ = 3

———————————-

Wasn’t sure what you were asking for with this this question, but hope it helped.

Answer: 3

Step-by-step explanation:

Since the trifle cake uses 1 ½ cups of sugar and the chocolate twice as much sugar as the trifle cake you should multiply 1 ½ x 2 which would equal 3. So, 3 cups of sugar should go into the cake. (This is my first answer to a question so I'm sorry if I'm confusing)

In linear equation, Number of members in liberal party = 32 * 77 = 2464

What does the term "linear equation" mean?

A mathematical function where the variables only occur in the first degree, where the constants are multiplied, and where the only possible combinations are addition and subtraction.

45% Of liberals switch to the conservative party

total number of eligible votes in the country =7700

Number of members change to liberal to conservative  = 45% of 7700

                                                         = 45/100 * 7700

                                                          = 45 * 77 = 3465

32% of conservative  switch to the liberals party  = 32 % of 7700

                                                      = 32/100 * 7700

Total 20 students should go to the trip to not to lose money.

Cost of bus = 100 dollars

For students the charge is 7 dollars per student.

Amount professor donated to defray the cost is 40 dollars.

School is charging 10 dollars per student for the trip.

Therefore, reduced cost = 100 - 40 = 60 dollars

Profit earned from each student is 10 - 7 = 3  dollars.

Hence, minimum students should go to the trip will be 60 ÷ 3 = 20.

Since, 20 × 3 = 60, the cost is covered and no money is lost.

The number of tapes cut is 3 pieces.

He has a roll of tape that is 4 1/2 yard long.

He cuts the tape into pieces that are each 3/2 yard long.

Therefore, the number of roll of tape cut can be calculated as follows:

Initial length of the tape in yard = 4 1 / 2 = 9 / 2 yards

Length of the tape cut in yard = 3  /2 yards

Hence,

number of tape cut = 9 / 2 ÷ 3 / 2

number of tape cut =  9 / 2 × 2 / 3

By using the method of subtraction, the profit earned by charles is £4.8

To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

Given that,

There are 15 pens in each pack.

Each pack costs £4.20.

Charles sells each pen for 60p but he only manages to sell of the pens.

60p x 15 = 9

So, the profit earned by charles is 9- 4.20 = 4.8

Therefore, the profit earned by charles is £4.8

The numerical value of side RS of the rectangle with a perimeter of 144 units is 30 units.

A rectangle is simply a 2-dimensional shape with parallel opposite sides equal to each other and four angles are right angles.

The perimeter of a rectangle is expressed as;

P = 2( l + w )

Given the data in the question;

First we determine the value of the variable z, plug the given values into the perimeter formula and solve for z.

P = 2( l + w )

144 = 2( (4z + 2 ) + (3z) )

144 = 2( 4z + 2+ 3z )

144 = 2( 7z + 2 )

144 = 14z + 4

14z = 144 - 4

14z = 140

z = 140/14

z = 10

Now, find the numerical value of side RS.

Width RS = 3z

RS = 3( 10 )

RS = 30

Therefore, the length of side RS of the rectangle is 30 units.
