Answer:

put the value of x in equation you get value of y

and vice versa.

Answer:

5/7 x = 1/7

x = (1/7) / (5/7)

x = (1/7) * (7/5)

x = 7 / 35

x = 1 / 5 or .2

Step-by-step explanation:

Answer: 3 3/9+7 6/11 = 10 87/99

Step-by-step explanation:

a. 3 3/9+7 6/11 = 10 87/99

First and foremost, we need to know the lowest common multiple of 9 and 11 which is 99.

Therefore, 3 3/9 + 7 6/11 would be:

= 3 33/99 + 7 54/99

= 10 87/99

This is correct

b. 2 3/8 + 6 4/5 = 8 12/40

First and foremost, we need to know the lowest common multiple of 8 and 5 which is 40.

Therefore, 2 3/8 + 6 4/5 would be:

= 2 15/40 + 6 32/40

= 8 47/40

= 9 7/40

Since the answer gotten is 8 12/40. This is wrong.

c. 3 3/7 + 4 2/3 = 7 2/21

First and foremost, we need to know the lowest common multiple of 7 and 3 which is 21.

Therefore, 3 3/7 + 4 2/3 would be:

= 3 9/21 + 4 14/21

= 7 23/21

= 8 2/21

Since the answer gotten is 7 2/21. This is wrong.

d. 4 5/6 + 5 5/7 = 9 10/13

First and foremost, we need to know the lowest common multiple of 6 and 7 which is 42.

Therefore, 4 5/6 + 5 5/7 would be:

= 4 35/42 + 5 30/42

= 9 65/42

= 10 23/42

This is wrong as the answer gotten is 9 10/13

Therefore, the true option is

3 3/9+7 6/11 = 10 87/99

Answer:

Option (4)

Step-by-step explanation:

Vertices of ΔABC are,

A → (-9, 3)

B → (-9, 6)

C → (0, 3)

If the given triangle is rotated 180° about the origin image triangle will have the vertices as,

Rule for the rotation,

(x, y) → (-x, -y)

A' → (9, -3)

B' → (9, -6)

C' → (0, -3)

If a point (x, y) is dilated by a scale factor of 'k',

Rule for the dilation,

(x, y) → (kx, ky)

Since, ΔA"B"C" is smaller than ΔABC,

Therefore, dilating ΔA'B'C' by a scale factor = [tex]\frac{1}{3}[/tex]

Image triangle ΔA"B"C" will be,

A" → (3, -1)

B" → (3, -2)

C" → (0, -1)

Therefore, Option (4) is the correct option.

Answer:

$3.0375

Step-by-step explanation:

Original price of dinner = $2.25

If cost percentage of 35%, then the additional cost paid will be;

35% * 2.25

= 0.35 * 2.25

= $0.7875

Target price = Original price + additional cost

Target price = $2.25 + $0.7875

Target price = $3.0375

Answer:

80%

Step-by-step explanation:

Let's call the past exam mark m,

m*105%=84

m*105/100=84

m=84/(105/100)

m=80

Hope this helps!

Answer:

80

Step-by-step explanation:

new value = 84

old value = n

can use percent change formula:  (new value - old value) / old value = 5/100

[tex]\frac{84-n}{n}[/tex] = [tex]\frac{5}{100}[/tex]

cross-multiply (you can simplify 5/100 to be 1/20 first):  20(84 - n) = n

1680 - 20n = n

1680 = 21n

n = 80

Answer:

The answer is x=27/28

Step-by-step explanation:

Solve for x by simplifying both sides of the equation, then isolating the variable.

The solution of the expression is,

⇒ x = 27/28

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 2x - 1/4 + x/3 = 2

Now, Solve the expression as;

⇒ 2x - 1/4 + x/3 = 2

⇒ 2x + x/3 = 2 + 1/4

⇒ 7x/3 = 9/4

⇒ 7x = 27/4

⇒ x = 27/28

Answer:

€16.875 is the answer

Step-by-step explanation:

£22.50/3*100

=16.875

Answer:

D. It has a single solution: X=-3, y= 26.

Step-by-step explanation:

3x + y = 17

x + 2y = 49 ➡ x = 49 - 2y now write this information in the first equation instead of x

3x + y = 17 ➡ 3(49 - 2y) + y = 17

147 - 6y + y = 17 add like terms

147 - 17 = 5y

130 = 5y divide both sides by 5

26 = y we can calculate the value of x using this information

3x + y = 17 ➡ 3x + 26 = 17 subtract 26 from both sides

3x = -9 divide both sides by 3

x = -3

Answer:

1. The car is traveling at a constant speed  2. The car stopped 3. The speed is decreasing

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

You recall the relation between speed, distance, and time is ...

  speed = distance / time

The graph is of distance vs. time. that means speed is the slope (distance/time) of the curve on the graph. If the slope is zero (a horizontal line), distance is not changing, and the speed is zero. That is, the vehicle has stopped.

If the slope is a positive constant, the vehicle is traveling at a constant speed.

If the slope is high, but becoming lower as the curve progresses left-to-right, then the speed starts high, but becomes lower: the vehicle is slowing down.

__

The graphs, left-to-right, represent a vehicle that is ...

  traveling at constant speed

  stopped

  slowing down

Answer:

AB = 3.9CM ; A = 51° ; C = 39°

Step-by-step explanation:

Base BC = 4.8cm

AC = 6.2cm

Angle B = 90°

Using trigonometry, the length of AB can be obtained thus :

AB^2 = AC^2 - BC^2

AB^2 = 6.2^2 - 4.8^2

AB^2 = 38.44 - 23.04

AB^2 = 15.4

AB = sqrt(15.4)

AB = 3.92 cm

Angle A :

Using :

Sinα = opposite / hypotenus

Sinα = 4.8 / 6.2

Sinα = 0.7741935

α = sin^-1 (0.7741935)

α = 50.73

A = 51° (approximately)

Angle C ;

(A + B + C) = 180 (Sum of angles in a triangle)

51 + 90 + C = 180

141 + C = 180

C = 180 - 141

C = 39°

Answer:

The quotient of two integers may not always be an integer.

Therefore, I do not agree when a student says that the sum difference, product, and quotient of two are always integers.

Step-by-step explanation:

The student is not largely correct!

The sum, difference, and product of two integers is indeed always an integer.

But, the quotient of two integers may not always be an integer.

i.e.

4/2 = 2

i.e.

2/3 = 0.67

Therefore, I do not agree when a student says that the sum difference, product, and quotient of two are always integers.

Answer/Step-by-step explanation:

4x - 7 = -2x + 12 (Given)

Add 2x to both sides

4x - 7 + 2x = -2x + 12 + 2x (Addition property of equality)

6x - 7 = 12 (Simplication)

Add 7 to both sides

6x - 7 + 7 = 12 + 7 (Addition property of equality)

6x = 19 (Simplification)

Answer:

The answer is below

Step-by-step explanation:

Given that:

y = 4x - 5

y = 3x - 2

This problem can be solved graphically by plotting the graphs of both lines, and the x and y coordinate of the intersection of both lines would give the solution to the problem. Also, the problem can be solved simultaneously by:

Step 1: subtract the second line equation from the first line equation to get

0 = x - 3

x = 3

step 2: Put x = 3 in equation 1 to get

y  = 4(3) - 5

y = 7

Therefore the solution = (x, y) = (3, 7)

Answer: 1a. f(2) is an x-value

1b. f(x) = 4 is a y-value

1c. f(-10) is an x-value

1d. m(x) = 64 is a y-value

2.  f(4) = 17

3.  x = 39

Step-by-step explanation:  In general, if there is an equal sign, the output f(x) is a y-value. if the expression is f(#) with a number in the parentheses, that is the value to insert for x.

2.) f(x) = 2x + 9

f(4) = 2(4) + 9

f(4) = 8 + 9

f(4) = 17

3. f(x) = 5x -3

192 = 5x -3

192 + 3 = 5x

195 = 5x

39 = x

Answer:

Han's mixture tastes stronger, because...

Han's uses 6 2/3 cups of water for every 1 cup of orange juice concentrate.

Clare uses 7 1/2 cups of water for every 1 cup of orange juice concentrate.

Step-by-step explanation:

Claire

Cups of water = 2 1/2 cups

Cups of orange juice = 1/3

Cups of water for every cup of orange juice = 2 1/2 ÷ 1/3

= 5/2 × 3/1

= 15/2

= 7 1/2

Han:

Cups of water = 1 2/3 cups

Cups of orange juice = 1/4 cups

Cups of water for every cup of orange juice = 1 2/3 ÷ 1/4

= 5/3 × 4/1

= 20/3

= 6 2/3
