Answer:

x=1

Step-by-step explanation:

Factor out the common term 22.

4x+4(3-2x)=2\times \frac{2(2x+1)}{4}+5

4x+4(3−2x)=2×  

4

2(2x+1)

​   +5

2 Simplify  2\times \frac{2(2x+1)}{4}2×  

4

2(2x+1)

​   to  2x+12x+1.

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

Simplify  2x+1+5 to  2x+6.

4x+4(3-2x)=2x+6

Expand.

4x+12-8x=2x+6

Simplify  4x+12-8x  to  -4x+12.

-4x+12=2x+6

Add 4x to both sides.

12=2x+6+4x

Simplify  2x+6+4x  to  6x+6.

12=6x+6

Subtract 6 from both sides.

12-6=6x

Simplify 12−6  to  6.

6=6x

Divide both sides by 6

1=x

Switch sides.

x=1

Answer:

The slope would be 1/4.

Step-by-step explanation:

To find the perpendicular slope first you have to set this equation to y

to do this you use the subtraction prop of equality and you will get 12x-9= -3y

then you divide by -3 on both sides to get y by itself

you will get -4x+3=y

now that you know the slope is -4, you must find the negative reciprocal slope of this which means you have to flip the numerator and denominator and make the sign its opposite.

The perpendicular slope would then be 1/4.

Answer:

A. Count by hand.

B. Divide 20 by 2.

Step-by-step explanation:

The midpoint between two points is found by the mean of their coordinates.

Endpoints at (0,0) and (20,0)

So we have x coordinates of 0 and 20. Their mean is:

[tex]\frac{20 - 0}{2} = 10[/tex]

So we can find both counting by hand, or dividing 20 by 2.

Answer:

x=-2

Step-by-step explanation:

5 times (6 plus x) = 20

6 plus x = 4

x = 4 - 6

x = -2

Answer:

-2

Step-by-step explanation:

Let the number be x

5 × (6 + x) = 20

6 + x = 20/5

6 + x = 4

x = 4 - 6

x = -2

Answer:

$10,253.04

Step-by-step explanation:

Answer:

$23.25

Step-by-step explanation:

Step one:

given data

A store buys a shirt from the vendor for $15

The store makes a 55% profit

Required

The sale price of the shirt

Step two:

Percent profit= sale-cost price/cost price *100

subtitute

55= sale-15/15 *100

0.55= sale-15/15

cross multiply

sale-15= 0.55*15

sale-15=8.25

sale= 8.25+15

sale=$23.25

Answer:

Perimeter of figure is 31.85 inches

Step-by-step explanation:

We have a rectangle and semi-circle in the figure.

First we will find perimeter of rectangle and semicircle and add them to find perimeter of rectangle.

First find perimeter of rectangle

The formula used is: [tex]Perimeter\: of\: rectangle=2(length+width)[/tex]

We have width = 7 in

length = 5 in

The perimeter is:

[tex]Perimeter\: of\: rectangle=2(length+width)\\Perimeter\: of\: rectangle=2(5+7)\\Perimeter\: of\: rectangle=2(12)\\Perimeter\: of\: rectangle=24\:in[/tex]

The perimeter of rectangle = 24 in

Now, finding perimeter of semi-circle

The formula used is: [tex]Perimeter\: of\: semi-circle=\frac{\pi d}{2}[/tex]

Wee have diameter d = 5 in

So, perimeter is:

[tex]Perimeter\: of\: semi-circle=\frac{\pi d}{2}\\Perimeter\: of\: semi-circle=\frac{3.14\times 5}{2}\\Perimeter\: of\: semi-circle=7.85\:in[/tex]

So, Perimeter of semi-circle= 7.85 in

Now, finding Perimeter of figure

Perimeter of figure = Perimeter of Rectangle + Perimeter of semi-circle

Perimeter of figure = 24 + 7.85

Perimeter of figure = 31.85 inches

So, Perimeter of figure is 31.85 inches

Answer:

y = -17

Step-by-step explanation:

-12 - 5 = -17

Given:

The point is located at P(4,7).

It is translated along [tex]\left<1,3\right>[/tex].

To find:

The image of the given point after the translation.

Solution:

The point is translated along [tex]\left<1,3\right>[/tex]. So, the rule of translation is defined by:

[tex](x,y)\to (x+1,y+3)[/tex]

The point is located at P(4,7).

Using the above rule, we get

[tex]P(4,7)\to P'(4+1,7+3)[/tex]

[tex]P(4,7)\to P'(5,10)[/tex]

The image of given point after the translation is (5,10).

Therefore, the correct option is A.

Answer:

Anything 3 or more

Step-by-step explanation:

3 x 4 = 12.

12 > 10.

If you follow through with the next multiple of 4, 4, we get 16.

16 > 10.

This is true for any other multiple of 4, making any value 3 or me greater than 10.

Answer:

The equation for this is: [tex]3(n+10) = 42[/tex]

Step-by-step explanation:

We have that the number though is n.

Adds 10:

This means that now we have: [tex]n + 10[/tex]

Multiplies by 3:

This means that now we have: [tex]3(n+10)[/tex]

Gets 42:

This means that: [tex]3(n+10) = 42[/tex]

Answer:

a. The price of an apple is $0.5 and that of a banana is $0.8

b. 4

Step-by-step explanation:

Form simultaneous equations from the information.

For 5 apples and 4 bananas, and the total comes to $ 5.70 this can be;

5 a + 4 b = $5.70----------i

After he puts back 1 apple and 2  bananas, the equation will be;

4 a + 2 b = $3.60 -------------ii

Solve the two equations simultaneously as;

{5 a + 4 b = 5.70 }4 ---------making the a terms equal to eliminate them

{4 a + 2 b = 3.60}5

20 a + 16 b = 22.80 -------subtract the b terms

20 a  + 10b = 18.00

6 b = 4.80

b= 4.80/ 6

b=$ 0.8

Using equation i :

5a + 4b =$5.70

5a + 4*0.8 = 5.70

5a + 3.2 = 5.70

5a = 2.5

a = 2.5 / 5

a=$0.5

The price of an apple is $0.5 and that of a banana is $0.8

b.  

Let the number of apples be ------x

Let the number of bananas be-----x

This is because the target is equal numbers;

Form an equation for total cost as;

0.5 x + 0.8 x = $6

1.3 x = 6

x = 1.3 / 6 = 4.62

Maximum number of bananas to buy = 4

Maximum number of apples to buy = 4

However, he will have $0.8 remaining

The Expression (x + 2y – 2z) – (2x – 5y – 6z) is equivalent to -x + 3y + 5z

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.

Variables are the name given to these symbols because they lack set values.

In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.

Given:

(x + 2y – 2z) – (2x – 5y – 6z)

so, (x + 2y – 2z) – 2x + 5y + 6z

= ( x- 2x) + (2y+ y)+ ( 6z- z)

=  -x + 3y + 5z

Hence, (x + 2y – 2z) – (2x – 5y – 6z) is equivalent to -x + 3y + 5z
