Answers

Answer 1
Answer:

Answer:

The mixture contains 47 lb of Colombian Supreme and 3 lb of Mocha Java.

Step-by-step explanation:

We are given the following in the question:

Let x be the amount of Colombian supreme and y be the amount of Mocha java in the mixture.

Total amount of mixture = 50 lb

Thus, we can write the equation:

Total unit cost of mixture =  $5.93/lb

Cost of Colombian Supreme = $4.99/lb

Cost of Mocha Java = $5.99/lb

Thus, we can write the equation:

Solving the two equations by elimination method,

Thus, the mixture contains 47 lb of Colombian Supreme and 3 lb of Mocha Java.

To get a B in​ math, Alexandria Pappas must average 80 on five tests. Scores on the first four tests were 81​, 78​, 84​, and 75. What is the lowest score that she can get on the last test and still get a​ B?

Answers

X = score on the last test (fifth test)

To obtain the average, we add up the values and divide by 5 (as there are 5 tests). We want this average to be 80 so we can figure out x
(81+78+84+75+x)/5 = 80

Solve for x
(81+78+84+75+x)/5 = 80
(318+x)/5 = 80
318+x = 80*5
318+x = 400
x+318 = 400
x = 400-318
x = 82

The lowest score Alexandria can get is 82, so her average is 80. Any higher score on the fifth test leads to the average being larger than 80.

Answer: 82

As a check, you can add up the five scores (81, 78, 84, 75, and the new score 82 we just found) and then divide that sum over 5. You should get 80 as a result.

Solve -2.5n + 8.7 > 5.45.

n < 1.3
n > 1.3
n < -5.66
n > -5.66

Answers

Subtract the 8.7 from the 5.45. then you have -2.5n>-3.25. divide the -2.5 to both sides. it's dividing by a negative, so the sign flips and you get, n
5.45-8.7= -3.5
-3.5÷-2.5= 1.3

Since you divided by a negative number switch the signs. So it would be A. the first one

 Round your answer to the nearest hundredth. A flower garden is 11.25 meters long. Mr. Owens wants to make a border along one side using bricks that are 0.25 meters long. How many bricks does he need?

Answers

To find the answer just divide the length of a flower garden by the length of a brick:

11.25 / 0.25 = 45 (that's how many bricks are needed to be put).

There's nothing to round, but you can write it as a decimal to the hundredth place as 45.00.
