x = -6

Step-by-step explanation:

4x - 2 + 3x - 7 = -51

Simplify

7x - 9 = -51

Move Terms

7x = -42

Divide.

x = -6

good luck, i hope this helps :)

Answer:

-6

Step-by-step explanation:

4x-2+3x-7=-51

we take minus two to the other side and it becomes plus two and -51+2 is -49

4x+3x-7=-49

and we take minus seven to the other side it becomes plus seven and -49+7 iis -42

4x+3x=-42

4x+3X = 7x

7x = -42

and to remove the x we divide both sides by 7

x = -42/7

-42/7 = -6

x=-6

Bobby is 5 less than Kylie's age. Their combined
age is 43. How old is Kylie?

Answers

Answer:

Kylie is 24 years old

Step-by-step explanation:

kylie = x

Bobby=x-5

x+x-5=43

2x-5=43

2x=43+5

2x=48

X=24 years old

19

If you subtract 5 off of 43 and divide it by two you find Kylie's age. The reason you divide by two is because there are two people and it is a combined age, meaning you would divide by two.

Can somebody help me please !?

Answers

Answer:

option 4) x = 14  y = 7

Step-by-step explanation:

We are given a side angle and a side length so we can use trigonometry to find the solution

To find x we can use sine because the given side length is opposite to the angle so,

sin(60) = [tex]\frac{7\sqrt{3} }{x}[/tex]

solve for x and you get 14 (make sure you check that your calculator is in degrees)

for either use Pythagorean theorem or remove sine by tangent.

Answer:

x = 6.99 fty = 5.66 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA can remind you of the relevant relationships. The given side is the hypotenuse. x is the side opposite the given angle.

  Sin = Opposite/Hypotenuse

  sin(51°) = x/(9 ft)

  x = (9 ft)sin(51°)

  x ≈ 6.99 ft

__

  Cos = Adjacent/Hypotenuse

  cos(51°) = y/(9 ft)

  y = (9 ft)cos(51°)

  y ≈ 5.66 ft

15 ounces of canned corn for 2.55$

Answers

Answer:

0.17 over 1

Step-by-step explanation:

So, first we have to find a comman factor. between 255, and 15 the GCF is 15, so 255 ÷ 15 = 17      So that is:

            255 ÷ 15 = 17                

       __________    =  17/1  or 17              15 ÷ 15 = 1

Now we move the decimal into place so its $0.17 becaue 0.17 x 15 = 2.55

Rolando is making buttons that are shaped like circles. Each button has an area of
62 square centimeters. Which measurement shows the circumference of each of the buttons in centimeters?
Reminder: A=π r 2
Helppppp this is due in 5 mins!!!1 :(((

Answers

Lets work backwards. π r2 = 62 cm. 62 / 3.14 = 17.75. Square root of 17.75 = 4.21. Okay, now using the radius of 4.21 we will use the formula C = 2 πr. C = 2 (3.14)(4.21) = 2 (13.22) = 26.44. So the circumference of each button is approximately 26.44 cm.

The radius= 4.21 cm

The circumference of the circle is 26.44 cm.

we have given that

Area  = 62 square centimetres.

What is the formula for the area of circle

[tex]A=\pi r^{2}[/tex]

A=62 and pi=3.14

[tex]62=3.14r^{2}[/tex]

find the value of r square divide both side by 3.14

[tex]r^2=\frac{62}{3.14}[/tex]

[tex]r^2=17.75\\[/tex]

[tex]r=4.21cm[/tex]

[tex]circumference of circle =2\pi r[/tex]

[tex]C=3.14)(4.21)\\\\C= 2 (13.22) \\\\C= 26.44.cm[/tex]

Therefore we get,

The radius= 4.21 cm

The circumference of the circle is 26.44 cm.

Jennifer is walking along a giant size number line where each number is a step away. She starts at -19 and then moves to 9. From there she walks to -15, turns around and walks to 16. Here she stops to count her number of steps so far. If she wants to have a total of 100 steps, on what number might she land on this number line?

Answers

-1 or 33

-19 to 9 is 28 steps
9 to -15 is 24 steps
-15 to 16 is 31 steps

28+24+31=83 steps taken

100-83 leaves 17 steps left

Currently on 16 so add or subtract 17

To get -1 or 33

Jennifer might be landed on 33 of the number line.

What is Number system?

A number system is defined as a system of writing to express numbers.

She starts at -19 and then moves to 9

-19 to 9 is 28 steps

19+9=28 steps

From 9 she walks to -15, turns around and walks to 16.

9+15=24 steps

From -15 to 16 she walks

15+16=31 steps

The total number of steps

28+24+31=83 steps

she wants to have a total of 100 steps,

100-83 leaves 17 steps left

Currently on 16 so add or subtract 17

16+17=33 and 16-17=-1

Step-by-step explanation:

Given

[tex]First = 6\ blocks[/tex]

[tex]Second = 8\ blocks[/tex] east

Required

Determine the shortest possible distance

To better explain my solution, I've added an attachment that illustrates her movement.

Using the attachment as a point of reference, the shortest distance is calculated by calculating the length of the hypotenuse using Pythagoras theorem.

So, we have:

[tex]x^2 = 6^2 + 8^2[/tex]

[tex]x^2 = 36 + 64[/tex]

[tex]x^2 =100[/tex]

Take positive square root of both sides

Mrs. Jones attended a Southern Living home party. She purchased a vase which cost $34.99. The shipping charge was $3.00, and 8.25% sales tax was paid on the subtotal which included the shipping charge. How much did she pay for the vase?

Answers

Answer:

$41.12

Step-by-step explanation:

34.99 + 3 = 37.99

37.99 increase 8.25% =

37.99 × (1 + 8.25%) = 37.99 × (1 + 0.0825) = 41.124175

34.99 + $3.00 = $37.99
34.99 * 8.25/100 = $2.886675

round that number to $2.89

then add $37.99 and $2.89

the answer would be 40.88
