Select the correct answer. Given the following formula, solve for a. A. B. C. D. <br> s=a+b+C/2
nexus9112 [7]

Hey there!

The answer to your question is a = s - b - C/2

<u>To solve for "a", we must get "a" on it's own side of the equal sign.</u> We can first subtract "s" from both sides:

<em>0 = a + b + C/2 - s</em>

Then, we can subtract a from both sides:

<em>-a = b + C/2 - s</em>

Finally, we divide both sides by -1, so a is by itself.

<em>a = -b - C/2 + s</em>

And we can rearrange it to the standard form:

a = s - b - C/2

Good luck, and hope it helped! Have a great day!

Layla is working two summer jobs, babysitting and tutoring. She can work at most 8 hours altogether between both jobs in a given
ExtremeBDS [4]

Answer:

The inequality equation is b+t\leq 8,

Step-by-step explanation:

Let the number of hours she work in Babysitting be b.

Also Number of hours she work in tutoring be t.

She can work at most 8 hours altogether between both jobs in a given week.

We need to find the Inequality expression that would represent the possible values for the number of hours babysitting, b  and the number of hours tutoring, t.

It can be framed as;

number of hours she work in Babysitting plus Number of hours she work in tutoring should be less than or equal to 8.

Expressing in mathematical form we get;

b+t\leq 8

Hence the Inequality is given as b+t\leq 8.

Answer:

Step-by-step explanation:

(1) f(x) = (x-1)^{2} - 36

First, let's expand the expression:

f(x) = x^{2} -2x + 1 - 36

f(x) = x^{2} - 2x - 35

Next, let's factor the quadratic:

f(x) = (x - 7)(x + 5)

Finally, set the equation equal to 0 to find the solutions

0 = (x - 7)(x + 5)

x = -5, 7

(2) During the step (x - 5)^{2} = 36, when you take the square root of both sides, you have two equations, rather than one:

x - 5 = 6 and x - 5 = -6, so the solutions should be x = -1, 11

(3)

\frac{1}{4}(x + 5)^{2} - 1 = 3

Add 1 to both sides

\frac{1}{4}(x + 5)^{2} = 4

Multiply both sides by 4

(x + 5)^{2} = 16

Take the square root of both sides

x + 5 =±4

Subtract 5 from both sides

x = -9, -1

The distance a spring will stretch varies directly with how much weight is attached to the spring if a spring stretches 11 inche
Studentka2010 [4]

Answer:

the weight that attached to the spring is 9.5 inches

Step-by-step explanation:

The computation is shown below:

inches per pound is

= 11 inches ÷ 75 pounds

Now for 65 pounds, it would be

=  11 inches ÷ 75 pounds × 65 pounds

= 9.5 inches

Hence, the weight that attached to the spring is 9.5 inches

The same is relevant and considered
