Mathematics
1 answer:
nordsb [41]4 years ago
6 0

Answer:

Option D: 2

Step-by-step explanation:

Given that:

4x + 2y = 6 ........... eq1

x-y = ....................... eq2

Using eq2:

x = 3 + y

Now put value of x in eq1

4(3 + y) + 2y = 6

By simplifying

12 + 4y + 2y = 6

12 + 6y =6

6y = 6 -12

6y = -6

Dividing both sides by 6 we get

y = -1

Now put value of y in eq2

x - (-1) = 3

x + 1 = 3

x = 3 - 1

x = 2

I hope it will help you!

A farmer plants a new type of corn and wants to quickly determine the yield, or total number of ears of corn, for the
miss Akunina [59]

Answer:

The statement which is not true about the sample is;

The sample of 10 plants was a census of the corn plants

Step-by-step explanation:

The statement out of the given statements which is not true about the sample is "The sample of 10 plants was a census of the corn plants"

The 10 unique number corn which the farmer randomly selects of which he then count the number of ears in the corn and multiply by 100 so as to quickly arrive at an estimate of the total number of ears of corn for the crop, without individually counting the ears on each plant from the 100 plants

A census is a counting and individual enumeration procedure to collect and record characteristic information and details of the all the members that make up a given population

Therefore, the farmer is finding an estimate of the number of ears of in the plants rather than taking a census of the ears of corn on each plants in the population of 100 plants

Find the sum.<br> 10 + 12 + 14 + ... + 80
lyudmila [28]

Answer:

1620

Step-by-step explanation:

The amount of even integers between 10 and 80 inclusive is 36 (5 for each interval of 10 [e.g., 10-19 has 5, 20-29 has 5] and one extra for 80).

Since the numbers are consecutive even numbers, we can use the fact that the sum of the numbers is equal to the average of the numbers, times the number of numbers.

The average of the numbers is 45, since \frac{10+80}{2}=45. We can use only the two outer numbers to determine the average since the numbers are all evenly spaced as they are consecutive even numbers.

45\times36=1620, so the sum is 1620.

1/2 divided by5 in fraction form
erik [133]

Answer:

1/10

Step-by-step explanation:

1/2 ÷ 5

First you must use the form KCF, or Keep Change Flip

Keep the first integer (1/2)

Change the symbol (÷) > (×)

Flip the last remaining integer (5) > (1/5)

You remain with

1/2 x 1/5

Keep the numerator the same (since 1 x 1 = 1)

Multiply the denominators ( 2 x 5 = 10)

The answer is 1/10
