Answer:

39 athletes

Step-by-step explanation:

There is a total of 45 people on the bus.  This INCLUDES the athletes (A), 2 coaches and 4 managers.

Therefore, we need to sum A, 2 and 4 and equal it to 45:

2 + 4 + A = 45  so we need to used equation d.

To calculate how many athletes are on the bus, find the value of A:

                                         2 + 4 + A = 45

Subtract 2 from both sides:  4 + A = 43

Subtract 4 from both sides:        A = 39

Need answer for 6 and 7 question ASAP will give brainlist to who answered
Arturiano [62]

Answer:

6.  x = 2

7.  35721

Step-by-step explanation:

<h3><u>Question 6</u></h3>

Given equation:

8^{-4} \times 8^7=8^{2x-1}

\textsf{Apply the exponent rule} \quad a^b \cdot a^c=a^{b+c}:

\implies 8^{-4+7}=8^{2x-1}

\implies 8^{3}=8^{2x-1}

\textsf{Apply the exponent rule} \quad a^{f(x)}=a^{g(x)} \implies f(x)=g(x):

\implies 3=2x-1

Add 1 to both sides:

\implies 3+1=2x-1+1

\implies 4=2x

Divide both sides by 2:

\implies \dfrac{4}{2}=\dfrac{2x}{2}

\implies 2=x

Therefore, x = 2.

<h3><u /></h3><h3><u>Question 7</u></h3>

Given identity:

\sf (a-b)^2=a^2-2ab+b^2

To find the square of 189, rewrite 189 as (200 - 11).

Therefore, a = 200 and b = 11.

Substitute these values into the given identity and solve:

\begin{aligned}\sf (a-b)^2 & =\sf a^2-2ab+b^2\\\implies \sf 189^2 = (200-11)^2 & =\sf 200^2-2(200)(11)+11^2\\& = \sf 40000 - 400(11)+121\\& = \sf 40000-4400+121\\& = \sf 35600+ 121\\& = \sf 35721 \end{aligned}
