Answer:

n=-4

Step-by-step explanation:

First, subtract 3n on both sides. This results in -3=n+1. Then, subtract 1 on both sides. The answer is n=-4.

Answer:

Step-by-step explanation:

We have the equation:

$3n-3=4n+1$

Let's solve for n. To do so, we want to isolate it.

Let's use the subtraction property of equality to subtract 3n from both sides:

$(3n-3)-3n=(4n+1)-3n$

The left side will cancel...

$-3=(4n+1)-3n$

Subtract on the right:

$-3=1n+1$

Remember that 1n is the same as just n. So:

$-3=n+1$

Now, let's use the subtraction property of equality again to subtract 1 from both sides:

$(-3)-1=(n+1)-1$

The right side will cancel. Subtract on the left:

$-4=n$

Symmetric property:

$n=-4$

So, our answer is B.

And we're done!

When Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75. When Judy worked 2 hours and Ben worked 6 hours, the

arsen [322]

Answer:

$15

Step-by-step explanation:

let the hourly rate of pay for Ben = B

let the hourly rate of pay for Judy = J

Judy worked 4 hours and Ben worked 1 hour, their combined pay was $75;

4J + B = 75 ----- i

Judy worked 2 hours and Ben worked 6 hours, their combined pay was $120

2J + 6B = 120 --- ii

Now, we should solve the expression;

Multiply equation ii by 2 and equation i by 1;

4J + B = 75 ----- i x 1 ; 4J + B = 75 -- iii

2J + 6B = 120 --- ii x 2 ; 4J + 12B = 240 ---iv

Now,

equation iv - iii;

11B = 165

B = $15

So, solving for J;

4J + B = 75

4J + 15 = 75

4J = 75 - 15 = 60

J = $15

Yes to both, and for future help, if you find a common denominator(the bottom one) by multiplication and one is higher, boom you have your answer.

The table below shows values for functions f(x) = g(x) <br> What are the solutions to f(x) = g(x)?

MakcuM [25]

The solutions to f(x) = g(x) are where the x-values for which the output f(x) is equal to the output of g(x).

What I mean by this is for instance, you input 7 into f(x) and g(x) and you get the same answer, then 7 is a solution.

Here, we are looking in columns two and three to see which rows are equal. It looks like when you input 0 into both f(x) and g(x), you get 2, and when you input 1 into both f(x) and g(x), you get 3. Therefore, (0,2) and (1,3) are your solutions.
