Answer:

x = 1

Step-by-step explanation:

4x + 8 = 12x

4 (1) + 8 = 12 (1)

4 + 8 = 12

12 = 12

your answer is x = 1

Answer:

4x+8=12x

8=8x subtract 4 on both sides

1=x divide by 8 on both sides

hopes this helps

have a good day :)

Answer:

11

Step-by-step explanation:

20 divided by 1.75= 11.42

Answer:

A and B are functions

Step-by-step explanation:

for A, none of the x's repeat which makes it a FUNCTION

for B, when it starts with x^2, it will always be a FUNCTION (its a quadratic)

for C, 10 repeats for the x so it is NOT A FUNCTION

Answer:

$4871.25

Step-by-step explanation:

You know that the dirt bike has been "marked down," so to find the percentage of the original cost, subtract 0.12 from 1 to get 0.88. Then, define x as the original cost, and set up an equation:

0.88x = 4286.70

You know that 4286.70 is 88% of the original cost, so 0.88 times the original cost will equal the marked down cost. Now, divide both sides by 0.88 to get the answer:

x = 4871.25

Answer:

5

Step-by-step explanation:

Answer:

x = 3 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

there's no x in the equation you wrote.

Did you mean?

2x + 8 = 15

Subtract 8 from both sides

2x = 7

Divide both sides by 2

x = 7/2

x = 3 [tex]\frac{1}{2}[/tex]

[tex]\sf\blue{The\:circumference\:of\:the\:circle\:is\:43.96\:cm.✅}[/tex]

Step-by-step explanation:-

Let "r" be the radius of the circle.

We know that,

[tex]\sf\purple{Circumference\:of\:a\:circle}[/tex] =

[tex]2 \: \pi \: r \\ = 2 \times 3.14 \times 7 \: cm \\ = 43.96 \: cm[/tex]

Answer:

Kayla sold 90 boxes of cookies.

Step-by-step explanation:

let's have X be the number of boxes Kayla sold.

x⇒100%

18⇒20%

Find x,

x=100/20 × 18

x=90

Responder:

A - B = {1, 4, 5}

Explicação passo a passo:

Conjunto A - Conjunto B; Isso significa que queremos um conjunto que contém apenas elementos que estão no conjunto A, portanto, os elementos do conjunto A que também estão presentes no conjunto B estão isentos.

A = {1, 2, 3, 4, 5}

B = {2, 3, 7}

A - B = {1, 4, 5}

Portanto, apenas] 1, 4, 5} são elementos do conjunto A e não do conjunto B

Answer:

???

Step-by-step explanation:

Answer:

48

Step-by-step explanation:

36          75%

----     =   -----

?            100%

36 * 100 = 3600

3600 / 75 = 48

Answer:

A & C

Step-by-step explanation:

for A - and + is always -

so 2.3-2.3 =0

for C - and - is always + so

-2.6--124 = -2.6+124

=121.4 which is positive

I’m pretty sure the answer is 4

I hope I’m right

Hope this helps :D

Answer:

x < 3

Step-by-step explanation:

-3 - 6(4x+6) > - 111

-3 - 24x - 36 > -111

-24x - 39 > -111

-24x > -72

dividing by a negative flips the sign

x < 3

Answer:

option 1.

circle

Step-by-step explanation:

A section is formed when a solid shape is sliced into two. A conic section is therefore formed when a cone, is sliced into two.

What determines the shape of the section now, is the angle at which the cone was sliced.

Normally, the base of a cone is a circle.  If we slice a cone using a straight line, which runs parallel to its base, we will still get another perfect cone, but with a smaller height.

If we look at the flat portion of the cone after it has been sliced, we will see that the cross-section is a circle.
