how many solutions does 3x+4=3x-2 have?

Answer:

100 + 80 = 180

20/100 X 180 = 36

selling price $36

Answer:

subtract 15 from both sides if you're solving for x

The first step should be subtracting 15 from both side.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. Every mathematical equation has the formula L.H.S = R.H.S.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given equation:

15-2.5x=40

Now, to solve for x the first step should be subtracting 15 from both side

15 - 2.5x - 15 = 40- 15

-2.5x = 25

Now, divide by (-2.5) from both side

-2.5x / (-2.5)= 25/(-2.5)

x= -10

Hence, the first step should be subtracting 15 from both side.

Step-by-step explanation:

unitary method..

find out how much 1kg will cost in the supermarket and multiply by 12.5kg

For the supermarket

1.83/2.5= 0.732 for one kg.

for 12.5 kg

0.732× 12.5= £9.15

hence the farm shop price is lower than the supermarket price

Answer:  x+y =12

0.40x+0.50y =5.70

Step-by-step explanation:

Let x = Number of ears of yellow corn

y - Number of ears of peaches and cream variety.

AS per given,

x+y = 1 dozen

⇒ x+y =12     [1 dozen =12]

Cost per ear of yellow corn = 40 cents = $0.40    [1 dollar = 100 cents, 1 cent = 0.01 dollar]

Cost per ear of peaches and cream variety = 50 cents = $ 0.50

Total cost ( in$): 0.40x+0.50y =5.70

Required system of equations represents the number of ears of corn of each type that Larji purchased:

x+y =12

0.40x+0.50y =5.70

Answer:

x = [tex]\frac{32}{3}[/tex] (see below)

Step-by-step explanation:

First, use distributive property:

5 (x + 8) = 8 (x + 1)

5x + 40 = 8x + 8

Then, simplify the equation by combining like terms. You want to isolate the variable to one side of the equation so you can solve for it. Here what I'm talking about:

5x + 40 = 8x + 8

-5x            -5x

-------------------------

40 = 3x + 8

-8           -8

-----------------

32 = 3x

Now, divide both sides by 3 to get the value of x:

3x = 32

x = [tex]\frac{32}{3}[/tex]

or

x ≈ 10.7

Answer:

x= 32/3

Step-by-step explanation:

5(x+8)= 8(x+1)

5x+40=8(x+1)

5x=40=8x+8

5x+40=8x+8

5x+40-40=8x+8-40

5x=8x-32

5x=8x-32

5x-8x=8x-32-8x

-3x=-32

-3x = -32

(Divide both by -3)

x=32/3

Answer:

[tex]\dfrac{5}{3}\ \text{pounds}[/tex]

Step-by-step explanation:

George bought a bag of dog food that was 1/3 pounds.

George fed his dog 5 times with this bag of food.

We need to find how many pounds of food did the dog eat at each feeding. Let it be x.

[tex]x=\dfrac{1}{3}\times 5\\\\x=\dfrac{5}{3}\ \text{pounds}[/tex]

So, the dog eat [tex]\dfrac{5}{3}\ \text{pounds}[/tex] of food at each feeding.

Answer:

99 votes for ice cream

Step-by-step explanation:

4 + 11 + 8 + 7 = 30

270/30 = 9

to find the predictions multiply the votes by 9

ice cream has 11 votes

11 * 9 = 99

Answer:

99

Step-by-step explanation:

Add up total amount of votes

4+11+8+7 = 30

270/30 = 90

Set up ratio

11/30 = x/270

cross multiply

30x = 2970

divide both sides by 30 to get x by itself

x = 99

Answer:

Step-by-step explanation:

Evaluate the function. f(x) = 4x2 + 4x - 4 Find f(3)​

f(3) = 4 x 2 + 4(3) - 4

After this step conduct PEMDAS

f(3) = 4 x 2 + 12 - 4

f(3) = 8 + 12 - 4

f(3) = 20 - 4

f(3) = 16

Answer:

93.75 pounds

Step-by-step explanation:

Set up a proportion where x is the weight of a person on Earth:

[tex]\frac{200}{32}[/tex] = [tex]\frac{x}{15}[/tex]

Cross multiply and solve for x

32x = 3000

x = 93.75

So, the person would weigh 93.75 pounds on Earth

On Earth, a person weighing 93.75 pounds would weigh around 15 pounds on the moon.

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

If a person who weighs 200 pounds on Earth would weigh about 32 pounds on the moon, we can set up the following proportion to find the weight of a person on Earth who would weigh 15 pounds on the moon:

200 pounds : 32 pounds = x pounds : 15 pounds

200 pounds / 32 pounds = x pounds / 15 pounds

⇒ 200/32 = x/15

Apply the Cross-multiplication operation, we get:

⇒ 200 × 15 = 32 × x

Solving for x, we get:

⇒ x = (200 × 15) / 32

⇒ x = 3000/32

Apply the division operation

⇒ x = 93.75 pounds

Therefore, a person who weighs 93.75 pounds on Earth would weigh about 15 pounds on the moon.

Answer:

Purchase price of radio is Rs 444.

Step-by-step explanation:

It is given that:

Selling price of radio = Rs 365

Amount of loss = Rs 79

Let,

x be the purchase price.

Loss = Purchase price - Selling price

79 = x - 365

x = 365 + 79

x = Rs. 444

Thus,

Purchase price of radio is Rs 444.
