Answer:

(a) Equations for both

$y = 500 + 12x$ --- lifeguard

$y = 15x$ --- camp counselor

(b) Total pay for 5 days

Lifeguard pays $800

Camp counselor pays $375

(c) Which pays more

Lifeguard job pays more

Step-by-step explanation:

Let

$x \to hours$

$y \to total\ pay$

Given

Lifeguard job

$Signing\ bonus = \$500$

$Rate = \$12/hr$

Camp counselor job

$Signing\ bonus =\$0$

$Rate = \$15/hr$

Solving (a): The equation for both

The total pay for each job is calculated as:

Total Pay = Signing Bonus + Rate * Hours

So, we have:

Lifeguard

$y = 500 + 12*x$

$y = 500 + 12x$

Camp counselor

$y = 0 + 15 * x$

$y = 15x$

Solving (b): Total pay for 5 days

First, we calculate the total hours worked in 5 days

$x = 5hrs/day * 5days$

$x = 25hrs$

So, the pay for each is:

$y = 500 + 12x$

$y =500 + 12*25$

$y =800$ --- Lifeguard

$y = 15x$

$y = 15 * 25$

$y = 375$ --- camp counselor

Solving (c): Which job pays more

By comparing the solution in (b)

$800 > 375$

<em>Hence, lifeguard job pays more</em>

How many solutions are there for the equation below? -47=3x+7x

sashaice [31]

I’m pretty sure there is only one solution, and it would be -47=10X and then you would just solve it and get X= -4.7

Can someone help with this qs pls?<br> 4 − (−4)^−3

11Alexandr11 [23.1K]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Solve ⇨ 4 - (- 4)^-3

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\sf \: 4 - ( - 4 ) ^ { - 3 }$

Calculate -4 to the power of -3 and get -1/64.

$\dashrightarrow \sf \: ( - 4) ^{3 } \\ = \sf-\frac{1}{4 ^{3} } \\ = \sf - \frac{ 1}{4} \times - \frac{ 1}{4} \times - \frac{ 1}{ 4} \\ = \sf \: - \frac{ 1}{64}$

Come back to the equation & substitute -4³ as -1/64.

$\sf \: 4-\left(-\frac{1}{64}\right) \\$

The opposite of -1/64 is +1/64.

$\sf \: 4+\frac{1}{64} \\$

Add 4 and 1/64 to get 257/64 (take 64 as the LCM).

$\boxed{ \boxed{ \bf\frac{257}{64} = 4.01}}$
