Answer:

$\frac{c-3p}{7}$

Step-by-step explanation:

1) 4(2a+p)=c+p+a

2) Expand: 8a+4p=c+p+a

3) subract a and 4p: 7a=c-3p

4) Divide: a= $\frac{c-3p}{7}$

<h2>Writing an linear equation from a given scenario</h2>

Answer:

Choice B

<h3>Step-by-step explanation:</h3>

Please refer to my answer from this question to know more about writing a linear equation from a given scenario: brainly.com/question/24599307

Scenario: A submarine dives $70$ feet per minute.

We let $f$ , be the position of the submarine from sea level as a function of $t$ , the time (in minutes) since the submarine dived.

The given scenario states that for every minute, the position of the submarine decreases (because the submarine is going in a downward direction) by $70$ feet. So $f(t)$ can be defined as $-70t$ .

Now we can select two points for the graph. We can select points $(1, f(1))$ and $(2, f(2))$ .

Evaluation of function:

$f(1) = -70(1) \\ f(1) = -70$

$f(2) = -70(2) \\ f(2) = -140$

Our points are $(1, -70)$ and $(2, -140)$

Choice A doesn't touch our chosen points. In Choice C, it would be the case if the submarine is going in upward direct.

So the correct graph is Choice B.

find the area of a parallelogram if a base and corresponding altitude have the indicated lengths base 1 1/2 feet , altitude 6 in

Ostrovityanka [42]

The area of parallelogram is 108 square inches

Solution:

The formula for area of parallelogram is:

$Area = base \times height$

From given,

$Base = 1\frac{1}{2}\ feet = \frac{2 \times 1 + 1}{2} = \frac{3}{2}\ feet$

$Height = 6\ inches$

Convert feet to inches

1 feet = 12 inches

$\frac{3}{2}\ feet = \frac{3}{2} \times 12\ inches = 18\ inches$

Therefore, area of parallelogram is:

$Area = 18 \times 6\\\\Area = 108$

Thus area of parallelogram is 108 square inches
