Answer:

The answer is 4

90+15x+8x-2=180

Step-by-step explanation:

Original cost = 900

Cost after VAT = 990

VAT amount = 990 - 900 = 90

Rate of VAT = 90/900×100 = 90/9 = 10%

Answer:

(1+7v) (3u+8b)

Step-by-step explanation:

Hope this helps!!

The required solution would be (1+7v)(3u+8b) of the given expression.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have been given the expression as:

⇒ 21uv + 8b + 3u + 56bv

There is v common in 21uv and 56bv

There is b common in 8b and 56bv

There is u common in 21u and 3u

We have to Add and subtract the second term to the expression and factor by grouping, we get

⇒  (1+7v)(3u+8b)

Therefore, the required solution would be (1+7v)(3u+8b) of the given expression.

Answer:

-4.5

Step-by-step explanation:

If you are considering speed regardless of direction, the average speed is:

(24 + 16) / 2 = 40 / 2 = 20mph

Although if direction matters, then one number has to be negative since the directions are opposite:

(24 - 16) / 2 = 8 / 2 = 4mph (in the positive direction)

Answer:

120 (60 from each store)

Step-by-step explanation:

Given that:

Price for 10 pack of pencils at SupplyCo = $0.95

Price for 10 pack of pencils at SchoolShop = $1.45

Discount coupon at SchoolShop = $3.00

Let the number of packs of pencils bought = [tex]2x[/tex] (in pack of 10)

Then [tex]x[/tex] will be the number of packs of 10 bought at each store.

Therefore, price at SupplyCo for [tex]x[/tex] packs (in pack of 10) = [tex]0.95x[/tex]

And price at SchoolShop for [tex]x[/tex] packs (in pack of 10) = [tex]1.45x-3.00[/tex] (because there is a coupon of $3.00)

As per question statement, price at both the stores is same:

[tex]0.95x=1.44x-3\\\Rightarrow 0.5x=3\\\Rightarrow x=6[/tex]

Therefore, number of packs bought = [tex]2x\times 10 = 2\times 6\times 10 =\bold{120}[/tex] (60 from each store)

good luck

Step-by-step explanation:

The speed of first hiker is 4 mph and speed of second hiker is 5 mph.

Let the speed of first hiker is x mph.

Since If one walks at a rate that is 1 mph faster than the other .

so taht speed of second hiker = (x + 1) mph

It is given that, pair of hikers are 18 miles apart and they meet 2 hours later .So that,

                  2x + 2(x + 1) = 18

                       2x + 1 = 9

                       2x = 9 - 1 = 8

                      x = 8/2 = 4

Hence, the speed of first hiker is 4 mph and speed of second hiker is 5 mph.

Answer:

Vertical angles are always congruent.

Step-by-step explanation:

Vertical angles are formed when two straight lines intersect each other, thereby forming two pairs of opposite angles, which are called vertical angles. Thus, a pair of these vertical angles formed are congruent to each other. So therefore, if two angles are said to be vertical angles, it follows that they are congruent to each other.

Using the diagram attached below, we can see two straight lines intersecting each other to form two pairs of vertical angles:

<a and <b,

<c and <d.

Thus, <a is congruent to <b, and <c is congruent to <d.

Therefore, the standby that is true about vertical angles is that:

Vertical angles are always congruent.

we can describe the parts of the expression that the arrows

point to 3x-2 such as:  

                                                  ↑(x variable)

Step-by-step explanation:

Given the expression

[tex]3x-2[/tex]

point to [tex]3x-2[/tex].

we can describe the parts of the expression that the arrows

point to 3x-2 such as:  

                                                  ↑(x variable)

                                                 [tex]3x-2[/tex] ← (2 constant)

                                                 ↓

                                                  (3 coefficient)

Therefore, it is clear that:

Answer:

3x+1=2x+40

We move all terms to the left:

3x+1-(2x+40)=0

We get rid of parentheses

3x-2x-40+1=0

We add all the numbers together, and all the variables

x-39=0

We move all terms containing x to the left, all other terms to the right

x=39

Step-by-step explanation:

Answer:

x = 48

Step-by-step explanation:

Original equation:

1/3x + 1/2x = 40

Add 1/3x to 1/2x

5/6x

Equation Now:

5/6x = 40

Divide both sides by 5/6

x = 48

Answer: 62 Ft

Step-by-step explanation:

The shadow adds 13ft

How we know- 19 1/2 - 6 1/2 = 13 ft

So we need to take away 13ft to find out the goal post actual height

75-13= 62

9514 1404 393

Answer:

  XL = 13 cm, m∠L = 29°

  AC = 21 cm, m∠C = 29°

  PC = 13 cm, m∠Y = ??  (there is no angle Y in the figure)

Step-by-step explanation:

The figure on the right shows the triangles are isosceles, with XL = XN. That means also PA = PC. Those side lengths are all the same: 13 cm.

  PA = PC = XL = XN = 13 cm

In the same fashion, ...

  LN = AC = 21 cm

__

Of course, the angles have a similar relationship:

  ∠A = ∠C = ∠L = ∠N = 29°

The two base angles in the triangle add to 58°, so the third angle is ...

  180° -58° = 122°

  ∠P =∠X = 122°

_____

Additional comment

As is often the case in over-specified problems, the numbers shown are not consistent The attached figures show the length LN is actually incorrect for the angle and side specified for triangle ACP, or the angles are incorrect for the side lengths specified. What this means is that the answers you get will depend on how you work the problem. Above, we have taken the given numbers and relationships at face value, even though we know they are incorrect.

After the reflection over the line y=x, the image points are:

Step-by-step explanation:

We know that when a point is reflected cross the line y = x, the x-coordinate, and y-coordinate change places.

i.e.

Given

so after the points reflected cross the line y = x

P(x, y)                 →          P'(y, x)

A(-2, -1)               →          A'(-1, -2)    

B(-1, 3)                →          B'(3, -1)  

C(-3, 2)               →          C'(2, -3)

Therefore, after the reflection over the line y=x, the image points are:

Answer:

A

Step-by-step explanation:

Supplementary angles are angles that add up to 180 degrees. Essentially, you can make a straight line with them.

1 and 7 are supplementary

1 and 4 are verticle, so no.

2 and 6 are complementary, so no.

3 and 6 are complementary, so no.
