Answer:

Reduce each side by 1/3, 9m would be 3m, 12m would be 4m, 15m would be 5m.

Step-by-step explanation:

To make a triangle a fraction smaller (such as 1/3, 1/4, or 1/6) just multiply the sides by the fraction. To make a triangle a fraction bigger, multiply it by the sides but then add the solution to the original triangle to get a triangle a fraction bigger.

Answer: Your new triangle would have the side lengths 3 m, 4 m, and 5 m.

Step-by-step explanation:

To make a triangle 1/3 as long as the original, you can multiply each side length by 1/3 (or simply divide each side by 3) to get the new side lengths.

9 ÷ 3 = 3

12 ÷ 3 = 4

15 ÷ 3 = 5

Therefore, the new triangle would have side lengths of 3 m, 4 m, and 5 m.

I hope this helps! I attached a drawing of the triangle for reference c:

The weight of the dog in pounds will be 77.88 pounds.

We have a dog whose weight is 35.4 kilograms.

We have to find the weight of the dog in pounds.

We know -

1 kg = 2.2 pounds

So, 5 kg = 5 x 2.2 = 11 pounds

According to the question, we have -

Weight of Dog = 35.4 kg

Therefore, the weight of the dog in pounds will be -

W = 35.4 x 2.2 = 77.88 pounds.

Hence, the weight of the dog in pounds will be 77.88 pounds.

Answer:

b = -84

Step-by-step explanation:

x² + 28 = -112

x² - 84 = 0

ax² + bx + c = 0

1x² + 0x + (-84) = 0

a = 1; b = 0; c = -84

Answer: b = -84

Answer:

x = 34

Step-by-step explanation:

5(x + 7) = 6x + 1

Distributive property

5x + 35 = 6x + 1

Subtract 5x from both sides

35 = x + 1

Subtract 1 from both sides

34 = x

Explanation/Answer:

To convert, we need a common denominator.

So if, say, we multiply the denominator by 2, we must multiply the numerator by 2 as well.

1) 4/5+4/7

4x7/5x7 + 4x5/7x5

28/35+20/35

(Both have common denominators so we can add them)

28 +20/35= 48/35=1 13/35

2) 1/2+11/8

(We already have common denominator in one of the numbers so we only have to convert ONE of the fractions)

1x4/2x4+11/8

4/8+11/8=15/8= 1 7/8

3) 1/5+1/3

1x3/5x3+1x5/3x5

3/15+5/15=8/15

Hope this helped :D

Answer:
1. 48/35

2. 15/8

3. 8/15

Step-by-step explanation:

You have to make sure the denominator is the same before combining both fractions. Whatever you multiply by the denominator, you need to do to the numerator.

Answer:

Larger number = 30
Smaller number = 8

Step-by-step explanation:

Let x = larger number

Let y = smaller number

x + y = 38 ————> (1)

x = y + 22 ————> (2)

Substitute for x using first equation

(y + 22) + y = 38

2y + 22 = 38

2y = 16

y = 8

Substitute for y using second equation

x = 8 + 22

x = 30

-4 is the y-intercept and the 1/4 just use the rise over run and you'll find that it matches perfectly.

The value of x is less than or equal to 2.25.

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Simplification is to make something easier to do or understand and to make something less complicated.

Given

The expression is 47.75 + x ≤ 50.

The value of x.

The expression is 47.75 + x ≤ 50.

On simplifying,

47.75 + x ≤ 50

            x ≤  50 - 47.75

            x ≤ 2.25

Thus, the value of x is less than or equal to 2.25.
