PLEASE MARK BRAINLIEST

Step-by-step explanation:

a+2= b

5a - 8 =2b

a= b- 2

since(a= b- 2)

5(b-2) -8 = 2b

5b -10 - 8 = 2b

3b -18 =0

3b=18;b=6

since b =6

a= 6-2 ; a= 4

Answer:

134 people

Step-by-step explanation:

80 / .6 = 133.333

Answer:

134 people

Step-by-step explanation:

we can use cross multiplication to solve this problem:

we know that 60% is 80 people and 40% is x people (we put x because we don't know the exact number of how many people yet)

now we set it up:

[tex]\frac{80}{60}[/tex] = [tex]\frac{x}{40}[/tex]

= 60x = 3200

= x = 53.33333

now we add the two numbers of people up:

53.33333 + 80 = 133.3333

since it is a decimal, it would be safer to assume that there are 134 people

Answer: x = 7

Step-by-step explanation:

5x + 7 = 42

We then take 7 away from both sides:

5x = 35

Then, we need to make it so x = answer. To make 5x into x, we divide by 5 meaning that we next need to divide both sides by 5.

x = 7

Answer:

-155.15

-223.75

Step-by-step explanation:

Transaction 1 was a deposit of 360. The account had nothing in it before that deposit. After the 360 deposit the balance is 360.

Transaction 2 is -22.50. That means 22.50 was withdrawn (taken out) from the account. The balance after transaction 2 is 360 - 22.50 = 337.50.

Before transaction 3 takes place, the balance is 337.50.

After transaction 3 takes place, the balance is lower. It is now 182.35.

The amount of money taken out in transaction 3 is 337.50 - 182.35 = 155.15. Transaction 3 is -155.15.

The balance after transaction 3 is 182.35. The balance after transaction 4 is -41.40 which is lower than 182.35, so transaction 4 is again withdrawing money from the account.

The amount of transaction 4 is:

182.35 - (-41.40) = 223.75

Transaction 4 is: -223.75

Answer:

48,000

Step-by-step explanation:

The cost function by the given data is C(x) = 40,000 + 8x.

We are given that;

Monthly fixed cost = $40,000

The product cost for each unit produced= $8

Now,

The cost function is a function that gives the total cost of producing a certain number of units. The cost function depends on the fixed cost and the variable cost per unit. The fixed cost is the amount of money that the manufacturer has to pay regardless of how many units are produced, such as rent, salaries, utilities, etc. The variable cost per unit is the amount of money that the manufacturer has to pay for each unit produced, such as materials, labor, etc.

In this case, the fixed cost is $40,000 and the variable cost per unit is $8. To find the cost function, we need to add the fixed cost and the product of the variable cost per unit and the number of units.

We can use x to represent the number of units and C(x) to represent the cost function.

Then we have:

C(x) = fixed cost + (variable cost per unit)(number of units)

C(x) = 40,000 + (8)(x)

Therefore, by algebra the answer will be C(x) = 40,000 + 8x.

what's the question to this given data?

Answer:

7 milk chocolate

19 dark chocolate

Step-by-step explanation:

It is 2950 ounces in total, and dark chocolate is 100 ounces per bar and milk chocolate is 150 ounces per bar. There are 12 more dark chocolate bars so I multiplied 12 by 100 and that was 1,200. Then I took 2,950-1200=1,750. From there I subtracted 150 and 100 till I got to 0.

Number of bars of milk chocolate: 17

Number of bars of dark chocolate: 29

Let's use algebraic equations to solve the problem. Let's denote the number of bars of milk chocolate as "x" and the number of bars of dark chocolate as "y."

1. Weight equation: The total weight of the chocolates in the box is 2950 ounces.

We can express this as an equation:

150x + 100y = 2950  

2. Quantity equation: The number of bars of dark chocolate is 12 more than the number of bars of milk chocolate.

We can express this relationship as:

y = x + 12

Now, we have a system of two equations with two variables:

Equation 1 : 150x + 100y = 2950

Equation 2 : y = x + 12

To find the values of x and y, we can use substitution or elimination. Let's use substitution in this case.

From Equation 2, we can substitute the value of "y" in terms of "x" into Equation 1:

150x + 100(x + 12) = 2950

Now, we can solve for "x":

250x + 1200 = 2950

250x = 1750

x = 7

Now that we have the value of "x," we can find the value of "y" using Equation 2:

y = x + 12

y = 7 + 12

y = 19

So, the number of bars of milk chocolate (x) is 7, and the number of bars of dark chocolate (y) is 19.

Answer:

Step-by-step explanation:

−(−12−6x−3)

= 12 + 6x + 3

= 6x + 15.

So 3.5 − 6x  is not equivalent to −(−12−6x−3)

Both linear equations are not equivalent to each other and this can be determined by evaluating the equation (-(-12 - 6x - 3)) by using the arithmetic operations.

Given :

Equations  ---  -(-12 - 6x - 3) and (3.5 - 6x)

The following steps can be used in order to determine the given equations are equivalent or not:

Step 1 - Write the given equations.

=−(−12−6x−3)               ---- (1)

= (3.5 − 6x)                  ---- (2)

Step 2 - Multiply -1 by (−12−6x−3) in the equation (1).

= 12 + 6x + 3

Step 3 - Add 12 and 3 in the above expression.

= 6x + 15   ---- (3)

Step 4 - Now, compare equation (2) and equation (3).

6x + 15 [tex]\neq[/tex] 3.5 - 6x

So, from the above steps, it can be concluded that both linear equations are not equivalent to each other.

Answer:

let x be the smaller number.

let x + 2 be the larger number.

4 times the smaller number is 2 more than 3 times the larger number.

in equation form, this becomes:

4x = 3 * (x+2) + 2

simplify this to get:

4x = 3x + 6 + 2 which becomes:

4x = 3x + 8

subtract 3x from both sides of this equation to get:

x = 8

this means that x+2 = 10

the smaller number is 8 and the larger number is 10.

4 times the smaller number is equal to 32.

3 times the larger number + 2 is equal to 32.

requirements of the problem check out ok, so the solution is good.

the smaller number is 8.

the larger number is 10.
