How do you solve 19=15w-4(3w-1)

19 = 15w-4(3w-1) > subtract 15w from both sides
19-15w = -4(3w-1) > work out the -4(3w-1)
19-15w = -12w+4 > subtract 19 from both sides
-15w = -12w-15 > add 12w to both sides
-3w = -15 > divide by -3
w = 5

hope this helped and I hope I get brainliest answer bud :)

Remember, you can do anyting to an equation as long as you do it to both sides

19=15w-4(3w-1)
distribute
-4(3w-1)=-4(3w)-4(-1)=-12w+4

19=15w-12w+4
19=3w+4
minus 4 both sides
15=3w
divide both sides by 3
5=w
w=5

Find the length of the unknown side. Round your answer to the nearest tenth.

Paraphin [41]

Answer:

<em>The correct option is: 11.5</em>

Step-by-step explanation:

Suppose, the length of the unknown side is $x$

So, here the length of hypotenuse is 14 and the lengths of other two sides are 8 and $x$ .

As the given triangle is right angle triangle, so <u>using Pythagorean theorem</u>, we will get.........

$8^2+x^2= 14^2\\ \\ 64+x^2=196\\ \\ x^2=196-64=132\\ \\ x=\sqrt{132}=11.489...\approx 11.5$

<em>(Rounded to the nearest tenth)</em>

So, the length of the unknown side is 11.5

Answer:

a $A = 30 + 0.45 n$

b $A = 90.3$

c 0 customers

Step-by-step explanation:

Given

$Base\ Amount = 30$

$Rate = 0.45$ per customer

Solving (a): Amount (A) on n customers

This is calculated as:

$A = Base\ Amount + Rate * n$

$A = 30 + 0.45 * n$

$A = 30 + 0.45 n$

Solving (b): Amount on 134 customers

In this case: n = 134

So:

$A = 30 + 0.45 * 134$

$A = 30 + 60.3$

$A = 90.3$

Solving (c): Customers at noon.

At noon, the amount is 30.

So:

$A = 30 + 0.45 n$

$30 = 30 + 0.45n$

Collect like terms

$0.45n = 30 - 30$

$0.45n =0$

$n = 0$

) Tara earns twice as much per hour as Kayte.

Cerrena [4.2K]

Answer:

Austin's hourly wage is $8.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

Tara's hourly wage is x.

Kayte's hourly wage is y.

Austin's hourly wage is z.

Tara earns twice as much per hour as Kayte.

This means that $x = 2y$

Kayte earns $3 more per hour than Austin.

This means that $y = z + 3$

As a group, they earn $41 per hour.

This means that $x + y + z = 41$

What is Austin's hourly wage?

This is z.

$x + y + z = 41$

$y = z + 3$ and $x = 2y$ , so $x = 2(z + 3) = 2z + 6$

$x + y + z = 41$

$2z + 6 + z + 3 + z = 41$

$4z + 9 = 41$

$4z = 32$

$z = \frac{32}{4}$

$z = 8$

Austin's hourly wage is $8.
