Write an inequality for the sum of twice a number and 5 is at most 15. Use y as the variable.

Answers

Answer 1

Answer:

The answer to the problem is 5

Step-by-step explanation:

The sum of twice a number y and 5 is at most 15" can be translated mathematically into the following inequality:

2y + 5 ≤ 15 since the sum, 2y + 5, is at most 15 but could be less than 15.

To solve this inequality for n, proceed as follows:

First, subtract 5 from both sides of the inequality as you would in solving an equation:

2y + 5 - 5 ≤ 15 - 5

2y + 0 ≤ 10

2y ≤ 10

Now, to finally solve the inequality for the variable y, divide both sides of the inequality by 2 as you would in solving an equation:

(2y)/2 ≤ 10/2

(2/2)y ≤ 10/2

(1)y ≤ 5

n ≤ 5 which is all real number less than or equal to 5.

Test Values (y = -1/2, 0, 3, 5, and n = 7):

For y = -1/2:

2y + 5 ≤ 15

2(-1/2) + 5 ≤ 15

-1 + 5 ≤ 15

-4 ≤ 15 (TRUE)

For y = 0:

2y + 5 ≤ 15

2(0) + 5 ≤ 15

0 + 5 ≤ 15

5 ≤ 15 (TRUE)

For y = 3:

2y + 5 ≤ 15

2(3) + 5 ≤ 15

6 + 5 ≤ 15

11 ≤ 15 (TRUE)

For y = 5:

2y + 5 ≤ 15

2(5) + 5 ≤ 15

10 + 5 ≤ 15

15 ≤ 15 (TRUE)

For y = 7:

2y + 5 ≤ 15

2(7) + 5 ≤ 15

14 + 5 ≤ 15

19 ≤ 15 (FALSE)

Therefore, the possible values for y which will make the relevant inequality, 2n + 5 ≤ 15, a true statement are:

{y | y is a real number and y ≤ 5}

Answer 2
The answer for this problem is 5

It will take Bridget 8 nights to knit 40 centimeters. You can get this answer because if Bridget knits 15 centimeters in 3 nights then she knits 5 centimeters every night. From then on all you have to do is divide 40/5 to get the answer.

The hypotenuse of a right triangle is 50 mm. One leg of the right triangle is 30 mm. What is the length of the other leg? (4 points)
Group of answer choices

20 mm

40 mm

30 mm

60 mm

Answers

Answer:

40 mm

Step-by-step explanation:

It's 40 mm because the Pythagorean Theorem explains a^2 + b^2 = c^2.

This means the unknown number plus 30^2 = 50^2

What you want to do is 50^2 - 30^2= 20^2; which would be 2500-900=1600.

You got 1600 but that isn't your final answer. You want to find the square root 1600. So 1600 square rooted is 40.

40 mm is your final answer.

Please help answer this question thanks

Answers

Answer:

y = 0.005x + 20.

Step-by-step explanation:

First, we need to make the equation. We can use y = mx + b.

b is the y-intercept, and in this case, it is 20. Plug it in: y = mx + 20. Our first point on the graph is (0,20).

The slope is 0.005 (y = 0.005x + 20), which is too small to graph, if you look at the x-axis labels. But that's okay! Plug in a number for x that you know is on the x-axis, such as 2,000.

y = 0.005(2000) + 20 = 30

Remembering (x,y), we have our second point on the graph (2000, 30).

Let's look for one more.

y = 0.005(14000) + 20 = 90

Our third point on the graph is (14000, 90).

Now, lets look for those points on the graph and make our line.

what number do you multiply by itself to get 6.25???

Answers

Answer:

2.5

Step-by-step explanation:

The square root of 6.25 is 2.5.

Becuase 2.5 x 2.5 = 6.25

Hope this helps!

Answer:

2.5

Step-by-step explanation:

6.25 = 625/100

625/100 = (5×5×5×5)/(2×2×5×5)

{prime factorisation}

Pairing of common numbers =

{(5×5) × (5×5)}/{(2×2) × (5×5)}

{taking a single no. from the pairs}

= {5 × 5}/{2 × 5}

= 25/10

= 2.5

Answer:

y=5

Step-by-step explanation:

3y-5=2y

/add 5 to both sides/

3y-5+5=2y+5

simplify

3y=2y+5

subtract 2y from both sides

3y-2y=2y+5-2y
