Answer:

cant help sorry

Step-by-step explanation:

Step-by-step explanation:

[tex]4 5\div 15 = 3[/tex]

[tex] \frac{45}{15} = 3[/tex]

[tex] \frac{15 + 15 + 15}{15} = 3[/tex]

[tex] \frac{3(15)}{15} = 3[/tex]

[tex]3 \times \frac{15}{15} = 3[/tex]

[tex]3 \times 1 = 3[/tex]

[tex]3 = 3[/tex]

Answer:

b

Step-by-step explanation:

Answer:

100.8 cm

Step-by-step explanation:

Area of square= side * side

let,

side=x

Substitute values in above formula:

635 [tex]cm^{2}[/tex]=x*x

[tex]x^{2}[/tex]=635 [tex]cm^{2}[/tex]

Taking square root on both sides:

x=25.2cm

side=25.2cm

Now, Permiter=4* side

Perimeter=4*25.2cm

Perimeter=100.8 cm

Answer:

.50¢ or 50% because he gave away half

Step-by-step explanation:

(i)

that is really simple. for each point go vertically and horizontally to the x and y axis and see at what numbers you hit the axis.

A is -2 on x and +3 on y. so, it's coordinates are (-2, 3).

B is (4, 6).

(ii)

the gradient is also called the slope. it describes the "tilt" of the line.

the gradient or slope is expressed as ratio y/x indicating how many units y changes, when x changes a certain amount of units when going from one point to another.

from (-2, 3) to (4, 6) :

x changes by +6 units (from -2 to 4).

y changes by +3 units (from 3 to 6).

so, the gradient/slope = 3/6 = 1/2

(iii)

the general line equation is

y = ax + b

a is the gradient/slope and is always the factor of x.

b is the y-intercept (the y value when x = 0, meaning the point the line crosses the y-axis).

we have already the gradient or slope.

we get b either by reading that point from the chart (it looks like (0, 4)) or by using the coordinates of one of the known points as x and y values in the equation and solve for b. I just picked (4, 6) :

6 = (1/2)×4 + b = 2 + b

b = 4

hey, we were right before !

so, the full line equation is

y = (1/2)x + 4 or simple x/2 + 4

Answer:

120 Yards

Step-by-step explanation:

42 feet is equal to 14 yards.

So if 14 yards is walked in 7 seconds then 2 yards are walked in 1 second.

So if 2 yards are walked in 1 second and there are 60 seconds in a minute, then 120 yards are walked in one minute.

So the answer is 120 yards.

Answer:

(2, -3)

Step-by-step explanation:

Plug x = 2 into the equation y = 4x - 11

y = 4(2) - 11

y = 8 - 11

y = -3

Then, put x = 2 and y= -3 into an ordered pair.

(2, -3)

Answer:

(2,-3)

Step-by-step explanation:

y = 4(2) - 11

y = 8-11

y = -3

Answer:

5 minus 4 times of a number, that difference minus 8 times of something else.

Step-by-step explanation:

Answer:

3 terms: Term 1; 5

Term 2:4x

Term 3: 8y

Step-by-step explanation:

Put a / symbol before all operations, and you can see the terms

EX: 3/+7x/-(-49÷7)/x9

Answer:

yes

Step-by-step explanation:

1, 7, 13, 19, 25, ...

a = 1

common difference = d = 7 - 1 = 6

13 - 7 = 6

nth term is

a(n) = a + (n - 1)d

= 1 + (n - 1)6

= 1 + 6n - 6

= 6n - 5

6n - 5 = 331

6n = 331 + 5

6n = 336

n = 56

as n is an integer

331 is 56th term

Answer:

57 268 900 square miles

Step-by-step explanation:

If you are asking for the total land surface but if you are asking for the total including the water it is, 196.9 million mi²

Answer:

150 million square kilometres and 51 million square kilometres

Step-by-step explanation:

1. 15 million square kilometres is approximately 10% of the world's land surface and the total land surface of the world is 100%, so we can multiply 15 million km² by 10 to get 100% which is 150 million km².

2. 34% of the world's land surface is covered by some form of desert so we would have to find 34% of 150 million km² which is 51 million km² (150 million × 0.34)

Given info:

A = { a,b,c,d }

B = {b,d,c,f}

Find the following :

1) AUB

2)AnB

3) n(A)

4) n(B)

5) n(AUB)

6) n(AnB)

Solution :-

Given sets are A = { a,b,c,d }

⇛ Number of elements in A = 4

⇛ n(A) = 4

B = {b,d,c,f}

⇛ Number be f elements in B = 4

⇛ n(B) = 4

AUB

⇛ {a,b,c,d} U { b,d,c,f}

⇛ {a,b,c,d,f}

AUB = {a,b,c,d,f}

⇛ Number of elements in AUB = 5

⇛ n(AUB) = 5

and

AnB = {a,b,c,d} n { b,d,c,f}

⇛ AnB = { b,c,d}

⇛ Number of elements in AnB = 2

⇛ n(AnB) = 2

Answer:-

1) AUB = {a,b,c,d,f}

2)AnB = { b,c,d}

3) n(A) = 4

4) n(B) = 4

5) n(AUB) = 5

6) n(AnB) = 3

Answer:

m = 7

Step-by-step explanation:

2(m + 2) = 18

the first step is to distribute the 2 so we don't have parenthesis

2 x m = 2m and 2 + 2 = 4

now we're left with 2m + 4 = 18

we want to get m alone on one side so we have to subtract 4 from both sides

2m + 4 = 18

       -4    -4

we are left with 2m = 14

the last step is to divide and since we want m alone, we have to divide 2 from both sides

2m/2 = m

14/2 = 7

so m = 7

D.   a = ( y - k ) / ( x - h )^2

y = a ( x - h )^2 + k

=> y - k = a ( x - h )^2

=> ( y - k ) / ( x - h )^2 = a

Answer:first one infinently

Step-by-step explanation:

The solution of the equation are:

1. 6(x-3)+4x=5(2x-4)-2 → No solution.

2. 2 − 6 − 3 = 5 − (4 + 2) → No solution.

3. 6(x - 2) + 8 = 3(2x - 4) → No solution.

4. 4x + 8 - 6x + 12 = 3(x + 7) - 5x - 1 → One solution.

1. 6(x-3)+4x=5(2x-4)-2

Step 1: Distribute the numbers outside the parentheses:

[tex]\(6x - 18 + 4x = 10x - 20 - 2\)[/tex]

Step 2: Combine like terms:

[tex]\(10x - 18 = 10x - 22\)[/tex]

Step 3: Isolate the variable on one side:

10x - 10x = -22 + 18

0 = -4

The equation 0 = -4 is not true.

It means that the variable x has canceled out, and both sides of the equation are not equal.

So, there is no solution for this equation.

2. 2 − 6 − 3 = 5 − (4 + 2)

Step 1: Perform operations inside parentheses and simplify:

2 - 6 - 3 = 5 - 6

Step 2: Continue simplifying:

-7 = -1

The equation -7 = -1 is not true.

So, there is no solution for this equation.

3. [tex]\(6(x - 2) + 8 = 3(2x - 4)\)[/tex]

Step 1: Distribute the numbers outside the parentheses:

[tex]\(6x - 12 + 8 = 6x - 12\)[/tex]

Step 2: Combine like terms:

6x - 4 = 6x - 12

Step 3: Isolate the variable on one side:

6x - 6x = -12 + 4

0 = -8

The equation 0 = -8 is not true.

So, there is no solution for this equation.

4. [tex]\(4x + 8 - 6x + 12 = 3(x + 7) - 5x - 1\)[/tex]

Step 1: Combine like terms on each side of the equation:

-2x + 20 = 3x + 20 - 1

Step 2: Continue simplifying:

-2x + 20 = 3x + 19

Step 3: Isolate the variable on one side:

-2x - 3x = 19 - 20

-5x = -1

Step 4: Solve for x:

[tex]\(x = \dfrac{-1}{-5} = \dfrac{1}{5}\)[/tex]

The equation  [tex]x = \dfrac{1}{5}[/tex] is true, which means that the variable x has a unique value that satisfies the equation.

So, there is one solution for this equation.
