10x - 20 = 4x - 2

How would I do this step by step?​

Answer:

Step-by-step explanation:

for 3x +y = -5

it's [tex]x = \frac{-5 -y}{3}[/tex]

and for 2x + 3y = -8 it's

[tex]x = \frac{-8 - 3y}{2}[/tex]

Answer:

224,999,992.5

Step-by-step explanation:

i used the BEDMAS rule.

first of all i added 5+10 which is in the bracket.

then, i multiplied 5×2 because in bedmas rule .. tho division comes first in BEDMAS. we check what is comes first from multiplication and division.

after that . i multiplied 9999999×6 then, as you know. if a digit is before the bracket is multiplied to the digit inside the bracket. i mutiplied the product of 9999999×6 with 15.

i dunno what you meant by (5+10)%4. so i just assumed that you meant (5+10)÷4. after i got the product of 59,999,994 ×15. i divided it with 4. now as we are done with BEDM. now only addition and subtraction is left. there is no subtraction.. so i added the products and the quotient .

Now... add 5+10+224,999,977.5

you get the ans 224,999,992.5

Do correct me if i am wrong.

To solve this, all you need to do is compare the ratio to the amount of SUVS there are.

5/9 (SUVs to sedans)

140/? (SUVs to sedans)

140 ÷ 5 = 28

9 x 28 = 252

140/252

There are 252 sedans in the car dealership! :D

Answer:

252 Sedans

Answer:

Step-by-step explanation:

we have 18,000 people

growth 2% per year

time=11 years

18,000*2/100=360 growth per year

360*11=3,960.00

18,000+3,960=14,960

Answer:  The shadow of the tree is 280 feet long.

Step-by-step explanation:

We can use a ratio to solve this:

Use the Height to shadow for each. This works because the fractions must reduce to the same equivalent.

5/10 = 140/x

We can see that 5/10 is 1/2, so we need another fraction using 140 as the numerator that is equal to 1/2.  That's easy here: Multiply 140 × 2 to get the new denominator, 280 that replaces x. That is the length of the shadow.

If you have a less obvious ratio, you can use Cross Multiplication to solve the unknown value in the ratio:

5/10 = 140/x  Cross multiply the numerator of the left side times the denominator on the right side, and the denominator on the left side by the numerator on the right side:

5 × x = 10 × 140

5x = 1400  Divide both sides by 5 (the 5s "cancel" on the left)

5x/5 = 1400/5

x = 280

I hope this helps, especially when you see more questions like this in the future.

Hi. you've asked an incomplete question. However, I provided some explanation about algebraic expressions and numerical expression.

Step-by-step explanation:

First, we may wonder: What is a numerical expression? In simple words, they are mathematical expressions that contain numbers and operations (like +, -, ÷, ×).

For example, 7+70, 90-10, 60÷10, 5×4 are numerical expressions.

While an algebraic expression on the other hand is a mathematical expression that contains at least one variable.

Variables are letters or symbols (like x, y, p, q, etc) that represent an unknown number or value in a mathematical expression.

For example, 7x+70, 90y-10 are algebraic expressions since they contain at least one variable.

Answer:

90

Answer:

8

Step-by-step explanation:

8/2 equals 4 minus 10 is -6

Answer:

-6= n/2 -10

-12=n-20

-12-n=-20

-n=-20+ 12

-n=-8

n=8

Step-by-step explanation:

1. multiply both sides of the equations by 2

2.Move the N varaiableto the left hand side and change its sign

3. Calculate the sum of -20+12

4. change the signs from negative N to positive N giving you the value of 8

n=8

Solved.

Answer:

1 point

Step-by-step explanation:

Answer:

You would move each point on y=P(x) up by three. Or add 3 to each y coordinate

Step-by-step explanation:

This is because we're not manipulating the value of x before it gets multiplied by P.

For example:

If x is set to equal 5 and P equal to 2, then the parent function would have a coordinate of (5,10) since 2(5)=10 but the new function would have a coordinate of (5,13) since 2(5)+3= 13 due to order of operations (2×5 =10, then we add 3).

Answer:

Step-by-step explanation:

Step 1:

Plot y=P(x) from x=-a to x=a with x=0 as the middle point of the distance between a and -a.

Step 2:

Add the value of +3 to each point of y=P(x), ie, y=P(x)+3 meaning that the graph y=P(x) will be pulled up three units on the y axis.

Answer:

Please check the explanation.

Step-by-step explanation:

Given

C=24x+80

R=44x

To determine

What is the break-even point?

Given that

C represents the cost in dollars

R represents the revenue in dollars.

At the break-even point Cost (C) equals Revenue (R), so

R = C

44x = 24x+80

44x-24x = 80

20x = 80

divide both sides by 20

20x/20 = 80/20

x = 4

Thus, at x = 4 the value of Cost (C) equals Revenue (R).

i.e.

C = 24x+80 = 24(4)+80 = $176

R = 44x = 44(4) = $176

Answer:

(4, 176)

Answer:

Option A

Step-by-step explanation:

Domain is the set of x values or input values of a function.

Range is the set of y values or output values of a function.

Given relation is,

2x + y = 4

Set if input values of domain → {-5, 0, 6}

Table for the input - output values,

x       -5        0        6  

y       14        4       -8  

Therefore, range of the given relation will be the set of output values.

{14, 4, -8}

Option A is the answer.

Step-by-step explanation:

Answer:

25/32 kg

Step-by-step explanation:

The kinetic energy K of a body in motion measured in joules is given as

K = 1/2 mV^2

Where n is the mass in kg and V is the speed in m/s

Hence given that K is 25J and speed V is 8 m/s,

25 =1/2 * m * 8^2

25 = m *32

Divide both sides by 32

m = 25/32 kg
