Step-by-step explanation: Sorry the explination is long i got it of a website i use for my math tests.

Simplifying

3x + 3 = 6x + -57

Reorder the terms:

3 + 3x = 6x + -57

Reorder the terms:

3 + 3x = -57 + 6x

Solving

3 + 3x = -57 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

3 + 3x + -6x = -57 + 6x + -6x

Combine like terms: 3x + -6x = -3x

3 + -3x = -57 + 6x + -6x

Combine like terms: 6x + -6x = 0

3 + -3x = -57 + 0

3 + -3x = -57

Add '-3' to each side of the equation.

3 + -3 + -3x = -57 + -3

Combine like terms: 3 + -3 = 0

0 + -3x = -57 + -3

-3x = -57 + -3

Combine like terms: -57 + -3 = -60

-3x = -60

Divide each side by '-3'.

x = 20

Simplifying

x = 20

The painter should work at least 13.33 hours to earn $200.

An inequality is a mathematical statement showing the non-equal comparison between two expressions.

Given that, a painter earns $15 per hour. We need to find the minimum number of hours he must work to earn at least $200,

So, let the minimum number of hours be x,

15x ≥ 200

This will be the inequality,

To find the minimum number of hours we will find the value of x,

15x ≥ 200

Divide by 15

x ≥ 200/15

x ≥ 13.33

Hence, the painter should work at least 13.33 hours to earn $200.

Step-by-step explanation:

Volume of a sphere:

LSA = TSA of a sphere:

We have V = 764 m³, find the radius:

Find the surface area:

[tex] \boxed{\tt{ \bold{Hello\:Mister\:Brainly!}}}[/tex]

____________

S = 4πr²

S = 4π × (V = 4/3πr³)²

S = 4π × (764 = 4/3 × 3,14 × r³)²

S = 4π × (764 × 3/4 = 3,14r³)²

S = 4π × (573 ÷ 3,14 = r³)²

S = 4π × (r³ ≈ 182,5)²

S = 4π × (r ≈ 5,67)²

S = 4 × 3,14 × 5,67²

Step-by-step explanation:

subsititute the f value which is 2 into the equation so 1+(2)=3

Answer:

Step-by-step explanation:

First we are going to find the function which models the height of the

periscope lens at time t.

Let the 2 be height of the periscope.

The height of the periscope at the beginning is 24 inches. It ascends at 6

inches per second. The expression which describes how much it has raised,

at the moment, is 6t.

The function is sum of beginning height and how much it has raised, 2 = 24 + 6t.

To find maximum height of the periscope, we need to evaluate function

for + = 22.

2 = 24 + 6(22)

= 24 + 132

156

Substitute 22 for t.

Multiply.

Maximum height in inches is 156.

We know that 1 foot is 12 inches.

So the function that describes converting feet to inch is y :

= 12x. Where y

represents number of inches and a number of feet.

U = 12.2

156

12x

12

-n=

156

12

2 = 13

Substitute 156 for y.

Divide both sides by 12.

Maximum height in feet is 13.

The height function modeled by the periscope is an illustration of a linear function.

The given parameters are:

[tex]\mathbf{Start = 24\ inches}[/tex]

[tex]\mathbf{Rate = 6\ inches/second}[/tex]

The function model of the height is calculated using:

[tex]\mathbf{h(t) = Start + Rate \times t}[/tex]

Where: t represents the time in seconds

So, we have:

[tex]\mathbf{h(t) = 24+ 6\times t}[/tex]

This gives

[tex]\mathbf{h(t) = 24+ 6t}[/tex]

After 22 seconds, the height of the periscope would be

[tex]\mathbf{h(22) = 24+ 6 \times 22}[/tex]

Multiply

[tex]\mathbf{h(22) = 24+ 132}[/tex]

Add

[tex]\mathbf{h(22) = 156}[/tex]

Hence, the maximum height is 156 inches

OPTION 1, 3

Step-by-step explanation:

I don't know how to explain why these are the correct options, except for basing my observations from the given graph.

Option 1: Attah Shipping does deliver a 20-kg package for $60 [as given by coordinates, (20, 60) -- orange line].

Option 3: The 30-kg line is the last, right-most line on the graph. That's the last point where Kwan Shipping's blue line crosses (within the observable region of the graph). If you look carefully, it is the same height as where Attah Shipping's 25-kg mark is. This means that a 30kg package costs $75 for Kwan Shipping, while it costs Attah Shipping $75 to ship a 25kg package. (You could draw a horizontal line across y = 75 to see what I'm talking about).

Answer: 3.3 kg of Cu, 1.7kg of Sn

I abbreviate copper as Cu and tin as Sn.

Step-by-step explanation:

For 5 kg of $7.05$/kg bronze:  Let x be the mass of Cu.  The mass of Sn would be 5-x.

Multiply these two masses by their respective element cost.

Cu = ($6.20/kg)x  [The total value of copper in 5 kg of bronze]

Sn = ($8.70/kg)(5-x)  [The total value of tin in 5 kg of bronze]

We know that:

($6.20/kg)x + ($8.70/kg)(5-x) = $7.05

Solve for x.  I get

x= 3.3 kg of Cu

5-x = 1.7kg of Sn

==

Check the result for 5 kg of bronze:

(3.3 kg of Cu)*($6.20/kg) = $20.46 cost of Cu

(1.7kg of Sn)*($8.70/kg) =     $14.79  cost of Sn

Thus, the total cost for 5kg of bronze is $35.25.  That makes it $7.05/kg.

Answer:

$18

Step-by-step explanation:

.20 x 50 = 10 + 8 = 18

Step-by-step explanation:

these intercepts are also points.

for an y- intercept x =0.

for an x- intercept y = 0.

so, we have the points (6,0) and (0, 2).

the regular equation for a line is

y = ax + b

(0, 2) gives us b directly :

2 = a×0 + b = b

and from there with the second point

0 = a×6 + 2

0 = 3a + 1

-1 = 3a

a = -1/3

so, the equation is

y = (-1/3)x + 2

and transform to standard form

3y = -x + 6

x + 3y = 6

that is the same as

2x + 6y = 12 of the answer options.
