Answer:

r = 4

Step-by-step explanation:

Simplifying

3r + -3 = 9

Reorder the terms:

-3 + 3r = 9

Solving

-3 + 3r = 9

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + 3r = 9 + 3

Combine like terms: -3 + 3 = 0

0 + 3r = 9 + 3

3r = 9 + 3

Combine like terms: 9 + 3 = 12

3r = 12

Divide each side by '3'.

r = 4

Simplifying

r = 4

What is the equation of this line in slope
Alex

Answer:

The Answer is: y - 8 = 5/3(x - 3)

Step-by-step explanation:

Given the y intercept form:

y = 5/3x + 3

Note that the slope is 5/3.

Find a point on the line.

Choose x = 3, solve for y:

y = 5/3(3) + 3

y = 5 + 3

y = 8

This give you the point:

(3, 8)

Use this to substitute into the point slope equation:

y - y1 = m(x - x1)

y - 8 = 5/3(x - 3)

Leyan bought 234 pounds of apples for $1.32 per pound, 112 pounds of peaches for $1.20 per pound, and some tomatoes, all from a
velikii [3]

Answer: See explanation

Step-by-step explanation:

I think your question isn't well written and that 234 was meant to be 2.34 and 112 was meant to be 1.12

Let the amount spent on tomatoes be x.

The information given in the question can then be used to form an equation as thus:

Apples + Peaches + Tomatoes = $9.63

(2.34 × $1.32) + (1.12 × $1.20) + x = $9.63

$3.0888 + $1.344 + x = $9.63

x = $9.63 - ($3.0888 + $1.344)

x = $9.63 - $4.4328

x = $5.1972

The amount spent on tomatoes will be $5.1972

An experiment was conducted to evaluate the success of an Ebola virus vaccine. The subjects were unaware of the treatment they w
Irina-Kira [14]

Answer:

your answer would be

B complexity

I agree that it is B but would suggest that you also consider the implications of each answer. They are all technically correct.

A is correct simply due to the fact that the longer time passes without an ebola cure, the more people can be potentially infected with it, resulting in less healthy individuals that may be able to volunteer to test potential ebola vaccines. Scientists need healthy volunteers from affected regions in order for rapid clinical trials to occur.

B is correct because of the nature of epidemics. A combination of technical, social, economic, and geographical obstacles slow the progress and dissemination of ebola vaccine information.

C is correct because finance impacts everything from finding resources used in studying ebola to distributing vaccines to affected areas. Economic imbalances or money shortages negatively impact research.

D is correct due to many social factors (more of a subjective answer). Some people think that vaccine distributors discriminate against certain ethnic groups. Others think the governments/other organizations are not effective enough at managing the situation. Still others feel that the search for a cure is not being approached in the right way. In all, there are multiple ways to oppose different aspects of ebola research.

Ultimately, B is correct because it seems to capture the meaning of A, C, and D together.
