How much money did you receive from selling the brownies?

Answers

Answer:

10×12= 120 so you would 120 brownie.

so 120 × 37 for each is 4440 so your answer would be 4440. I used desmos.com, it is very helpful. You should give it a try!

Answer:

$44.40

Step-by-step explanation:

Each tray has 12 brownies, And you sold 10 trays

Given that 2 x − 2 y = 23 Find x when y = 9

Answers

Answer:

[tex]x=41/2=20.5[/tex]

Step-by-step explanation:

So we have the equation:

[tex]2x-2y=23[/tex]

And we want to find x when y is 9.

So, substitute y for 9 and solve for x:

[tex]2x-2(9)=23[/tex]

Multiply:

[tex]2x-18=23[/tex]

Add 18 to both sides:

[tex]2x=41[/tex]

Divide both sides by 2:

[tex]x=41/2=20.5[/tex]

So, our answer is 20.5

Answer:

20.5

Step-by-step explanation:

2x - 2y = 23

2x - 2(9) = 23

2x -  18 = 23

2x = 23 + 18

2x = 41

x = 20.5

A 525 gram rock contains 25.0% gold.How many grams are gold?

Answers

Answer:

131.25 gram is gold

Step-by-step explanation:

Rock = 525 gram

Gold = 25.0% of the rock

To determine how many grams of the rock are gold,

Find 25.0% of 525 gram

= 25/100 × 525

= 0.25 × 525

= 131.25 gram

Gold = 131.25 gram of the rock

Therefore,

131.25 gram of the rock is gold

What is the solution to this equation?
-8x + 4 = 36
O A. x= -4
O B. x = 4
O c. x= -5
O D. x = 5

Answers

Answer:

A

Step-by-step explanation:

So we have the equation:

[tex]-8x+4=36[/tex]

Subtract 4 from both sides:

[tex]-8x=32[/tex]

Divide both sides by -8:

[tex]x=-4[/tex]

And we're done!

The answer is A

Answer:

A. x = -4

Step-by-step explanation:

We are given the equation:

-8x+4=36

We want to solve for x. Therefore, we must isolate x on one side of the equation.

4 is being added to -8x. The inverse of addition is subtraction. Subtract 4 from both sides of the equation.

-8x+4-4=36-4

-8x=36-4

-8x=32

x is being multiplied by -8. The inverse of multiplication is division. Divide both sides of the equation by -8.

-8x/-8=32/-8

x= 32/-8

x=-4

Let’s check our solution. Plug -4 in for x and solve.

-8x+4=36

-8(-4)+4=36

32+4=36

36=36

This checks out, so we know our solution is correct.

The solution to the equation is A. x=-4

If six times a number is decreased by fourteen, the result is 124. What is the number

Answers

Answer:

[tex]\large\boxed{23}[/tex]

Step-by-step explanation:

Six times a number is decreased by fourteen, the result is 124.

Write an equation that represents this

(6 * x) - 14 = 124

Multiply 6 by x to remove the parenthesis

6x - 14 = 124

Add 14 to both sides of the equation

6x = 138

Divide both sides of the equation by 6

x = 23

The unknown number is [tex]\large\boxed{23}[/tex]

Hope this helps :)

Answer:

138

Step-by-step explanation

6x-14=124

6x=124+14

The width of a rectangle measures (4.4d-4.3)(4.4d−4.3) centimeters, and its length measures (7.6d+4.7)(7.6d+4.7) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

Answers

Answer:

Perimeter, P = (24d+0.8) cm

Step-by-step explanation:

Given that,

Width of rectangle, B = (4.4d−4.3) cm

Length, l = (7.6d+4.7)

Perimeter is equal to the sum of all sides. A rectangle have 4 sides. The opposite sides of a rectangle are equal. So,

Perimeter = 2(L+B)

P = 2[(7.6d+4.7)+(4.4d−4.3)]

Collecting like terms

P = 2[(7.6d+4.4d)+(4.7−4.3)]

P=2(12d+0.4)

P = 24d+0.8

So, the expression for the perimeter of the rectangle is (24d+0.8) cm.

A full-time employee who works 40 hours per week earns $20.50 per hour. Estimate that person's income. Round 52 weeks to 50 weeks per year, and round the hourly wage to the nearest dollar for the estimate. What is the estimated of annual income?

Answers

Given :

Full-time employee who works 40 hours per week earns $20.50 per hour.

To Find :

The weekly income and annual income after round off .

Solution :

Weekly income is given by :

[tex]C =40\times 20.50\\\\C=\$ 820[/tex]

Now , round off of hourly in come to nearest dollar is $21 .

So , new weekly income is :

[tex]C'=40\times 21\\\\C'=\$ 840[/tex]

Now , annual income is :

[tex]A=C'\times 50\\\\A=\$840\times 50\\\\A=\$42000[/tex]

Therefore , weekly income and estimated of annual income is $42000 .

Hence , this is the required solution .

Edward has deposited $847 in a savings account that earns interest at a rate of 2.2% compounded daily. What will the account balance be in 18 years

Answers

Answer:

$1,257.63

Step-by-step explanation:

A= p(1+r/n)^nt

P = principal = $847

r= interest rate = 2.2%

n= 360 per year

t= 18 years

A= p(1+r/n)^nt

= 847(1+0.022/360)^360*18

= 847(1+0.000061)^6,480

= 847(1.000061)^6,480

=847(1.4848)

= $1,257.63

Total balance in 18 years = $1,257.63
