Answer 1

Answer:

Negative 7/40 or - 7/40

Step-by-step explanation:

Answer 2

Answer: -7/40

Step-by-step explanation:

first multiply the two negatives so it becomes (2-|-1/4+2 x 3/5|) /(-6)

then that becomes (2- | -1/4 + 6/5 | ) /(-6)
the sum of those two fractions become (2- | 19/20|) /(-6)

(2-19/20)/(-6)

2 - 19/20 /-6

21/20 /-6

multiple both by a negative so that become -21/20 /6

multiply the 6 with the recirocal so it becomes 1/6

-21/20 and 1/6 turn into -7/20 and 1/2 by canceling out with the greatest common factor of 3

now multiply both and u get -7/40

D the answer is 8 . 8 is the answer

Answer:

a = 8

Step-by-step explanation:

Write the equation:

7/a = 35/40

Divide:

7/a = 35/40

7/a = 35 ÷ 40

7/a = 0.875 (convert back to a fraction)

7/a = 7/8

Multiply:

8a • 7/a = 7/8 • 8a

8 • 7 = a • 7

56 = 7a

Divide to get answer:

56/7 = 7a/7

8 = a

a = 8

if the perimeter of the triangle is 19 meters what is the length of the longest side

HELP THIS IS DUE TODAY

Answers

Answer:

17+1+1

Step-by-step explanation:

Answer:

The longest side can be anything but the number of the longest side has to be less than the other 2 sides after you add them together.

example:    The longest side can be 9 and the other 2 sides are 5. When you add them both together they equal 10 which is more than 9 so it would work.

WORTH 50 POINTS!!!!!!!!!! a gardener made a scale drawing of a lawn with a scale factor of 1:15. the dimensions of his garden are 6 inches long by 3 inches wide. his partner plans to make another scale drawing of the lawn, but with a scale of 1:5
. what are the dimensions of his scale drawing?

Answers

Answer:

D. the length is 18 inches and the width is 9 inches.

Step-by-step explanation:

Given information:

Scale = 1 : 15.Dimensions of the lawn in the scale drawing = 6 in × 3 in.

Therefore, to find the actual dimensions of the lawn, multiply the given scale dimensions by 15:

⇒ Length = 6 × 15 = 90 in

⇒ Width = 3 × 15 = 45 in

If the gardener's partner plans to make another scale drawing of the lawn with a different scale of 1 : 5, to find the dimensions of his scale drawing, divide the actual dimensions by 5:

⇒ Length = 90 ÷ 5 = 18 in

⇒ Width = 45 ÷ 5 = 9 in

Therefore, the dimensions of his scale drawing are the length is 18 inches and the width is 9 inches.

An alternative way to approach this problem is to calculate the difference between the two scales.  It is clear that the original scale of 1 : 15 is 3 times the new scale of 1 : 5.  Therefore, simply multiply the original dimensions by 3 to find then new dimensions of the scale drawing with a scale of 1 :5.

For this equation the easiest thing to start with ratios:

16:4 (scale of 4 due to 4 x 4 being = to 16)

For the y-2 to find y you first will put 8/4 (your scaling back), so 2 so 4-2 would be 2 which makes that equal to y.

Knowing that 8 is the size on the one side these are equal on the top so x-3 had to equal 8, so 11-3=8 so...

x=11

y=2

16:4
4x4=16

8/4
4-2
2=y

Answers

Answer:

AB = 10

EF = 2

Step-by-step explanation:

to find the scale factor you have to divide the bigger scale by the smaller one which would be

(5x)/5    and   4/x

since both scale factors should be the same you can set them even to each other

(5x)/5=4/x

solve for x

(5x)/5=4/x

x=4/x

x^2=4

x=2

(5x)/5=4/x
x=4x
x^2=4
x=2

Answers

Answer: slope = 1/2

Step-by-step explanation:

slope = 1/2

It’s 1/2 cuz it goes as rise over run and the rise is the y and the run is the x

Answer:

y=4x

Step-by-step explanation:

if you look at the line you'll see it takes 4 x's to = 1 y, every time you go right 1 you go up 4

Answer:

The slope is 4.

Step-by-step explanation:

Step 1:

Slope can also be found by using the formula, Y2-Y1/X2-X1

In this case, our first point is the origin, so x would be 0 and y would be 0. On the second point, our x is -1, and our y is -4.

So, we can make the solution, -4-0/-1-0.

You can simplify this into, -4/-1, and then into 4.

Therefore, the slope is 4.

Step 2:

M is our slope, so in our y=mx equation our m = 4.

If you substitute in the m, you get y=4x.

Answer:

y=4x.

Hope this helped!

In the division problem, they moved the decimal point to the right and did the same to the problem inside of the division symbol to make it easier. After you would finish doing all the division, you would count the amount of spaces behind the decimal point and put the decimal point that many spaces in the answer. Loren forgot to count the decimal point that you moved right at the beginning. To summarize, Loren forgot the decimal point you moved at the beginning and Maddie is correct.

find how much longer it would take Betty to read a 360-pageants book than Sheldon.
Make a table of
Betty hours longer to read the book.

Answers

First step, make ratios:

Pages: time

Sheldon: 9 pages: 15 minutes

Betty: 18 pages: 60 minutes (1 hour)

To find how long it would be for 360 you divide:

9/15 is 0.6 pages: 1 minute and 18/60 is 0.3 pages per minute

When you make the table here would be the equation:

y=.06x for Sheldon and y=.3 for betty (plug in times and create a table)
