What's the answer please

Answer:

x = 4

Step-by-step explanation:

1. Write the equation

3/4x = 2x - 5

2. Get the variables on the same side

Let's subtract 2x! Now, since math is a veryyy jealous subject, you're going to do it on the other side too!

-1.25x = -5

3. Divide both sides by -1.25

x = 4

Thank you for the points!!!

Answer:

the ratio used was 1:19

Step-by-step explanation:

let a be the action figure version

let r be the real iron man

let's list out the important things.

a = 4''

r = 6'4''

one foot has 12 inches

convert r into inches:

6 × 12 = 72           (6 feet in r)

       r = 76''          (72 + 4)

r = 76''

a = 4''

ratio is 4:76

simplify

4:76

2:38

1:19

the ratio they used is 1:19

good luck,

Step-by-step explanation:

Answer:

B is the answer!

Step-by-step explanation:

Answer:

6

Step-by-step explanation:

105 is a composite number (not prime).  If you decompose 105 into its prime factors (see attached image), you get 105 = 3 x 5 x 7.  This means that the product 105 can only be written this way; any other way, for example 15 x 7 would not use numbers that are single digits.

The question boils down to how many ways the digits 3, 5, 7 can be arranged, using each digit exactly once.

That's a permutation problem, and it can be answered easily by thinking this way:  given the digits 3, 5, 7, there are 3 choices for the first digit, then 2 for the second digit (for EACH of the first choices), then only 1 choice for the final digit.

3 x 2 x 1 = 6 ways that 3, 5, 7 can be arranged to make a 3-digit number.  Here they are:

357, 375, 537, 573, 735, 753

Answer: 21

Step-by-step explanation: 21 + 21 = 21

Answer:

the number of viruses are in Dish A is 3,391 viruses

Step-by-step explanation:

The computation of the number of viruses are in Dish A is shown below:

Since there are 2826 square milimeters area

And, the population density of 1.2 viruses per square

So, the number of viruses in Dish A is

= 2826 × 1.2

= 3,391.2v viruses

Hence, the number of viruses are in Dish A is 3,391 viruses

The answer is B. 3,391 viruses

Good luck :)

Answer:

By cross multiplication

x = 5 × 30

x = 150.

150/5 = 30

30 = 30

Hence, the value of x is 30 units.

Answer:

the answer is x< −2 /3  y+ 2 /3 but it goes on the bottom

Step-by-step explanation:

Q: How might doing math slowly help with problems that are difficult to understand or hard to solve?

A: It calms you down. When you are stressed, you are most likely to get it wrong because you are panicking. This also helps because you can read the problem correctly and make sure you are doing it right, because in math, If you get 1 small thing wrong, you usually get the entire thing wrong.

I hope this helped!

Answer:

23w

Step-by-step explanation:

For 6days, She skates 3 * 6 = 18 miles

on weekend she skates 5 miles

Thus, In one week, she skates 23miles

In w week, she skates: 23w

in this exercise we have to know conversion, so it will be necessary to correct the space in time, which will represent in weeks:

28 weeks

So first, we have to calculate the total distance traveled in every day, like this:

[tex]days: 6*3=18\\weekends: 5*2=10\\total:18+10=28[/tex]

Answer: 61.58

Step-by-step explanation:

C = 2 π r = 2 · π · 9.8

π = pi

radius times pi (3.14) times 2 (because two radius makes the diameter)

9.8 times 3.14 times 2 = 61.57522in

Now we round.. 61.58

Answer:

3

Step-by-step explanation:

Answer:

a=6

b=-2

Step-by-step explanation:

You can use the hint provided on the mathswatch question page, I've attached it below

step 1

h(4) = ax+b = (ax4)+b = 4a+b

it is given in the question that h(4)=22, therefore 4a+b=22

step 2

work out the equation for inverse g

g^-1(x) = [tex]\frac{x-2}{3}[/tex]

step 3

input 14 into the equation in place of x to find g^-1(x)

[tex]\frac{x-2}{3} =\frac{14-2}{3} =\frac{12}{3} =4[/tex]

so, g(x)^-1=4

step 4

find h(1):

h(1) = (ax1)+b = a+b

so, h(1)=a+b

step 5

a+b=4 (as it is given in the question that g^-1(14) is equal to h(1))

step 6

Now you have two simultaneous equations:

4a+b=22

a+b=4

then, solve for a:

4a+b=22

- a+b=4  

3a=18

a=6

then, input answer for a into either equation (I've gone with the a+b=4 equation):

6+b=4

-6   - 6

b=-2

(p.s i know this is very late but hope it helps someone)

Answer:

the GCF is 3x^3

Step-by-step explanation:

Identifying the greatest common factor of an expression like this one involves finding the GCF of each term  when the terms are placed side by side:  the GCF of -15x^3 and 6x^4 is 3x^3, because 3 and x^3 are the largest factors of their type (constant, power of x) that will divide evenly into -15x^3 and 6x^4.

The end result is 3x^3(-5, 2x).  Once again, the GCF is 3x^3.

Answer:

57.6

Step-by-step explanation:

Parallel lines cut by transversals have proportional segments.

x = 57.6

Answer:

a) (4x® - 5x + 15) - (11 - 7x - 2x)

b)(9x- 6x® - 7x-2) + (10x - 8x + 11)

Step-by-step explanation:

a) (4x® - 5x + 15) - (11 - 7x - 2x)

b)(9x- 6x® - 7x-2) + (10x - 8x + 11)

Answer:

it nonlinear i think

Step-by-step explanation:

on the x it goes from a 3 3/5 to 5 2/5 then drops down to ten.

we already know this is wrong because linear means going straight and proportional when displayed on a graph instead of having zigzag and sharko lines

Answer:

The loan will be paid after 39 monthly installments.

Step-by-step explanation:

Since I am paying off a student loan in monthly installments, and after the 4th payment the remaining balance is $ 13,900, while after the 5th payment my remaining balance is $ 13,500, to determine the amount of payments in which the loan was agreed I must perform the following calculation:

13900 - 13500 = 400

400 x 5 = 2000

2000 + 13500 = 15500

15500/400 = 38.75

Thus, the loan will be paid after 39 monthly installments.

What are the options???
