can someone solve 5x − 7 = 13 step by step

(instructions: Add 7 to both sides: 5x = 20

Divide both sides by 5: x = 4)


Like the example below

Answer:

135°

Step-by-step explanation:

here's your solution

=> we know that , sum of all angles is

equal to 180°

=> hence ,we have two angles

=> 1st angle = 45°

=> 2nd angle = 9x + 18

=>. adding both angle

=> 45° + 9x + 18° = 180°

=> 63° + 9x = 180°

=> 9x = 180° - 63

=> 9x = 117°

=>. x = 117/9

=> x = 13°

=>. hence, the required angle = (13*7) + 18°

=> angle = 135°

hope it helps

Answer:

sin 0 = 24/25

cos 0 = 7/25

tan 0 = 24/7

Step-by-step explanation:

hey there!

sine = opposite divided by hypotenuse

the opposite of angle 0 is 24 and the hypotenuse is 25 so sin 0 = 24/25

cosine = adjacent divided by hypotenuse

the adjacent of 0 is 7 and the hypotenuse is 25 so cos 0 = 7/25

Tangent.= opposite divided by adjacent

the opposite of 0 is 24 and the hypotenuse is 7 so tan 0 = 24/7

See Explanation

Step-by-step explanation:

The question is incomplete as the polygon A (and other possible polygons to select from) are not given. So, I will answer on a general term.

Assume that Polygon A is a rectangle of dimension 2ft by 5ft.

[tex]Length = 2ft[/tex]       [tex]Width = 5ft[/tex]

Possible scaled copies can be gotten by multiplying the dimension of A by the same scale factor.

Take for instance, the scale factor k is:

[tex]k = 3[/tex]

A scaled copy of polygon A (say polygon B) is: 6ft by 15ft

This is gotten by:

[tex]Length = 2ft * 3 = 6ft[/tex]     [tex]Width = 5ft * 3 = 15ft[/tex]

The area of A is:

[tex]Area = 2ft * 5ft = 10ft^2[/tex]

The area of B is:

[tex]Area = 6ft * 15ft = 90ft^2[/tex]

See attachment for polygons

Comparison

The area of B is greater than the area of B.

This method can be applied to scale factors

Answer:

10

Step-by-step explanation:

The distance is equal to the modulus of Z1-Z2.

[tex]Z_1 - Z_2 = -7 - 6i - (-15 - 12i) = 8 + 6i\\|8 + 6i| = \sqrt{8^2 + 6^2} = \sqrt{64 + 36} = \sqrt{100} = 10[/tex]

Given that :

Fraction of pocket money spent by Jamal = 3/4

The number line is divided into 4 equal parts with distance between successive tick marks representing 1 of the whole = (1/4). Hence, 3/4 of the whole would mean 3 portions of the total 4 portions of the number line represents the amount spent by Jamal.

The fraction spent by Jamal is also labeled on the number line picture in the attached document.

Answer:

D

Step-by-step explanation:

You have to do the summation of all expenses so

1,750+3,260+3,500+4,332+6,652+4,880+15,000+3,448+18,380= 61,202

The total of taxes is composed of state taxes and federal taxes

3,448+18,380= 21,828

Set up a proportion to calculate the percentage

21,828 : 61,202 = x% : 100%

[tex]x\% = \frac{21828 \times 100}{61202} = \frac{2182100}{61202} = 35.67\%[/tex]

You can approximate the result to 36%

The percentage of the annual budget withheld for taxes is 36%.

The total budget of Ralph is calculated as follows;

T = 1,750 + 3,260 + 3,500 + 4,332 + 6,652 + 4,880 + 15,000 + 3,448 + 18,380

T = $61,202

Tax = 3,448 + 18,380

Tax = $21,828

The percentage of the annual budget withheld for taxes is calculated as follows;

[tex]= \frac{tax}{total \ budget} \times 100\%\\\\= \frac{21,828}{61,202} \times 100\%\\\\= 35.67 \ \%\\\\\approx 36 \ \%[/tex]

Answer: $657.53

Step-by-step explanation:

Circumference of a circle = πd

But in this case, it's a semi circle, so the circumference will be:

= πd/2

= (3.142 × 31) / 2

= 97.402/2

= 48.701

Then, the total amount of the fencing will be:

= 48.701 + 31

= 79.701

Then, the fencing cost will be:

= 79.701 × $8.25

= $657.53

Answer:

Step-by-step explanation:

Hey There!

they are asking for the slope in slope intercept form

y = mx + b

where m = slope and b = y intercept

The slope is change in y over change in x

as y goes up 4 x goes up 2

4/2=2 so the slope (or m ) is 2

The y intercept is at point (0,-4)

So the y intercept (or b) is -4

now we add everything together and get that the equation of the line is

y=2x-4

for 4

the best rule is D 2n+2

Why? because the rate of change is 2

and the y intercept is at (0,2) so the best rule would be 2n+2
