Answer 1
3x + 2y = 12
x = y - 1

3x + 2y = 12
3 (y - 1) + 2y = 12
3y - 3 + 2y = 12
5y - 3 = 12
5y = 15
y = 3

x = y - 1
x = (3) - 1
x = 2

answer:
(2, 3)

Kaitlyn solved the equation 5y=15 and found answer to be y=75. In complete sentence or two, explain what kaitylns error was? What did she do wrong? What is correct answer? Show your work and explain reasoning

Answers

Answer:

3

Step-by-step explanation:

Instead of dividing, Kaitlyn multiplied both sides by 5. Divide both sides by 5 to get the y by itself and you get 3

Answer:

y=3

Step-by-step explanation:

She assumed y=75, but if y=75 then you would multiply 75×5 and that doesn't equal 15. To find y you would need to divide 5 from both sides. Therefore 15÷5 would be equal to y=3. Hope this helps!

A boat travels 336 miles in 67
hours (with a constant speed).
How far can it travel in 58 hours
(with the same speed)?

Answers

Answer:

290.87 miles

Step-by-step explanation:

336 miles - 67 hours

x miles - 58 hours

Cross multiply

67x = 336 x 58

67x = 19488.

Divide both sides by 67

x = 19488/67

x = 290.87 miles

Answers

Given:

The reasoning problem is

42=164, 73=499, 51= 251, 29=?

To find:

The missing value.

Solution:

In the given reasoning problem, we need to square each digit then write them combinedly.

[tex]4^2=16[/tex]

[tex]2^2=4[/tex]

On combining these two, we get

[tex]42=164[/tex]

Similarly,

[tex]73=7^23^2=499[/tex]

[tex]51=5^21^2=251[/tex]

Using this pattern, we need write the square of 2 and 9 combinedly to find the value of 29.

[tex]29=2^29^2=481[/tex]

Therefore, the missing value is 481.

What Is The Estimated Weight Of Three Containers Weighing 1.656 kg each? (Math 5 Quarter 2, Week 5) I Need A Nice And Clear Answer

Answers

Answer:

[tex]Estimate = 5.0kg[/tex]

Step-by-step explanation:

Given

[tex]Weight = 1.656kg[/tex]

Required

Determine the estimated for 3 containers

Since the weight of all containers are the same, we simply multiply the given weight by the number of containers.

i.e.

[tex]Estimate = Number\ of\ containers * Weight\ of\ each[/tex]

[tex]Estimate = 3 * 1.656kg[/tex]

[tex]Estimate = 4.968kg[/tex]

[tex]Estimate = 5.0kg[/tex] --- approximated

So, the estimated weight is 5.0kg

Mr Morris built a fence to enclose his yard he put 3/4 of the fence on Monday on Tusday he put up 1/6 of the fence and on wensday he put up the rest of the fence what portion of the fence on Wensday

Answers

Answer:Portion put up on Wednesday =1/12

Step-by-step explanation:

Since we are dealing with fraction

Let the total fence = 1 whole

such that fence put up on Monday = 3/4

and fence he put p on Tuesday = 1/6

Since he put up the rest on Wednesday, To find the portion put up we have that

Portion put up on Wednesday =Total portion of fence - ( Portion put up on Monday and Tuesday)

=1- ( 3/4 + 1/6)

= 1-  18+ 4/ 24

=1- 22/24

= 2/24

Portion put up on Wednesday =1/12

What’s 8367 divided by 7

Answers

Answer:

1195.28

Step-by-step explanation:

We have a division problem which is 8,367 ÷ 7.

When it comes to division, you always look at the first number that is being split equally by the second number.

Follow the steps of the division problem :

Find how many times 7 goes into 8 :

7 * 1 = 7

Subtract 7 from 8 :

8 - 7

1

We have 1 in our thousands place, move down the number next to 8 in 8367 which is 3, and see how many times 7 goes into that number :

13

7 * 1 = 7

Therefore 7 only goes in once, put 1 next to 1 on top of the division problem, subtract 7 from 13 :

13 - 7

6

Move the 6 down from 8367 and see how many times 7 goes into that :

7 * 9 = 63

Subtract 63 from 66 :

3

Put 9 next to the one, as for now we have 119, now bring down the last value in 8367 and see how many times 7 goes into that :

37

7 * 5

35

Subtract 37 - 35 :

2

Therefore, our answer is 1195.28 , 1195 Remainder 2

Answer: The answer to 8367 divided by 7 equals 1195.285714 It can also be writtin as 1195.28 for short

Step-by-step explanation: The result of 8367/7 is a non-terminating, repeating decimal. The repeating pattern above, 285714, is called repetend, and denoted overlined with a vinculum.

This notation in parentheses is also common: 8367/7 = 1195.(285714): However, in daily use it’s likely you come across the reptend indicated as ellipsis: 8367 / 7 = 1195.285714… .

8367 divided by 7 in decimal = 1195.285714

8367 divided by 7 in fraction = 8367 divided 7

8367 divided by 7 in percentage = 119528.57142857%
