Answer:

1. {12,0}

hope it helps.

Answer:

3 and 4

Step-by-step explanation:

X - 9y = 12     If x=3 and y=-1

3 - (9*-1) = 12

3 +9 = 12

12 = 12

and

X - 9y = 12     If x=0 and y=-4/3

0 - (9 * -4/3) = 12

0 + 12 = 12

12 = 12

Answer:

1 19/360

Step-by-step explanation:

What we know:

The addends in this equation are 7/8 and 8/45.

First, find the LCM of 8 and 45. Since 8 and 45 don't have any common factors other than 1, just multiply the two numbers.

8 * 45 = 360

After that, find the equivalent fraction for both addends

7/8 * 45/45 = 315/360

8/45 * 8/8 = 64/360

Then, add the two new fractions together, and simplify if needed.

315/360 + 64/360 = 379/360 = 1 19/360

Answer:

E: x = 13

F: x = 1.5 or 3/2

Step-by-step explanation:

This is for E:

x + 2/3 = 5

All you do is first multiply 5 * 3

and you will get 15

x + 2 = 15

Then you subtract from 15

15 - 2 = 13

So x = 13

This is for F:

10(x - 1) = 5

So all you do is distribute the 100 with x -1

10 * x = 100x

10 * -1 = 100

10x - 10 = 5

Then you add 10 to 15 because the number is -10

5 + 10 = 15

10x = 15

Now you divide by 10 on both sides

10x/10 = 15/10

10x/10 = x

15/10 = 3/2

So the answer for F is 3/2 or 1.5

Step-by-step explanation:

Answer:

The remainder is 10

Step-by-step explanation:

The find the remainder when f(x) divided by g(x), find the value of x when g(x) = 0, then substitute it in f to find the value of the remainder

∵ f(x) = 3[tex]x^{5}[/tex] + 2[tex]x^{4}[/tex] + 5

∵ f(x) is divided by x - 1

∴ g(x) = x - 1

→ Equate g(x) by 0 to find x

∵ g(x) = 0

∴ x - 1 = 0

→ Add 1 to both sides

∵ x - 1 + 1 = 0 + 1

∴ x = 1

→ Substitute x in f by 1

∵ f(1) = 3[tex](1)^{5}[/tex] + 2[tex](1)^{4}[/tex] + 5

∴ f(1) = 3(1) + 2(1) + 5

∴ f(1) = 3 + 2 + 5

∴ f(1) = 10

∵ The remainder is the value of f(1)

∴ The remainder is 10

80

Step-by-step explanation:

Answer:

It is the first one

Step-by-step explanation:

The total number of tickets given away is 280

To do this, we make use of the following representations:

From the question, we have the following equations:

a = 20 + c --- 20 more adult than children

s = 3a ---- 3 times as many senior as adult

c = 40 --- number of children tickets

Substitute c = 40 in a = 20 + c

a = 20 + 40

a = 60

Substitute a = 60 in s = 3a

s = 3 * 60

s = 180

The total number of tickets is:

Total = a + c + s

This gives

Total = 60 + 40 + 180

Evaluate

Total = 280

Hence, the total number of tickets given away is 280

Answer:

Step-by-step explanation:

6+5=11

8/2=4

11x(4)2

The value of the expression 6 + 5 . (8 ÷ 2) 2 is 46.

BODMAS rule is a rule of calculating expressions which include more than one different mathematical operations.

BODMAS is an abbreviation for Brackets, Orders, Division, Multiplication, Addition and Subtraction.

So while calculating expressions including different operations, we should follow this order.

Here, the given expression is  6 + 5 . (8 ÷ 2) 2.

By BODMAS rule, we should calculate the expression in the bracket first.

8 ÷ 2 = 4

So, the expression becomes  6 + 5 × 4 × 2.

There are two operations, multiplication and addition here.

We should go for multiplication first.

5 × 4 × 2 = 40

The expression becomes 6 + 40 = 46.

Hence we got the value of the expression 6 + 5 . (8 ÷ 2) 2 as 46.

The decimal only contains two numbers, so it is a terminating fraction.

Answer:

The largest number of bundles he could create without any left over is 5.

Each bundle to contain 4 pencils, 16 pens and 11 markers

Step-by-step explanation:

Pencils = 20

Pens = 80

Markers = 55

a) What is the largest number of bundles he could create without any left over?

Find the highest common multiple of 20, 80 and 55

20 = 1, 2, 4, 5, 10, 20

80 = 1, 2, 4, 5, 8, 10, 16, 20......

55 = 1, 5, 11, 55

The highest common multiple of 20, 80 and 50 is 5

Pencils = 20 / 5

= 4

Pens = 80 / 5

= 16

Markers = 55 / 5

= 11

The largest number of bundles he could create without any left over is 5.

Each bundle to contain 4 pencils, 16 pens and 11 markers

Answer:

x = - 1, y = 1

Step-by-step explanation:

Given the 2 equations

2y + 7x = - 5 → (1)

5y - 7x = 12 → (2)

Adding the2 equations term by term will eliminate the term in x, that is

7y = 7 ( divide both sides by 7 )

y = 1

Substitute y = 1 into either of the 2 equationsand solve for x

Substituting into (1)

2(1) + 7x = - 5

2 + 7x = - 5 ( subtract 2 from both sides )

7x = - 7 ( divide both sides by 7 )

x = - 1

solution is x = - 1, y = 1

Answer:

−6a^5b+c

Step-by-step explanation:

=============================================

Work Shown:

Refer to the diagram below. I've added a line segment and two variables y and z. This forms two isosceles triangles.

The central angle 56 degrees subtends the same arc as the inscribed angle y. By the inscribed angle theorem, this means y = 56/2 = 28. The inscribed angle is always half of the central angle (when both angles subtend the same arc).

Focus on the smaller isosceles triangle that has angles 56, z and z. Those three angles add to 180

z+z+56 = 180

2z+56 = 180

2z = 180-56

2z = 124

z = 124/2

z = 62

Now focus on the larger isosceles triangle (angles y = 28, x+z and x+z)

We'll use the same trick as before.

(x+z)+(x+z)+(y) = 180

(x+62)+(x+62)+(28) = 180 ... plug in z = 62 and y = 28

2x+152 = 180

2x = 180-152

2x = 28

x = 28/2

x = 14

Step-by-step explanation:

The number of units that needs to be sold to earn at least $250 is 20.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The minimum amount that needs to be earned = $250

One unit cost = $5

The amount earned in the first week = $105

Number of units = x

The number of units to sell in the second week.

150 + 5x ≥ 250

5x ≥ 250 -150

5x ≥ 100

x ≥ 20

Thus,

20 units need to be sold to earn at least $250.
