Ok, so first convert both the numbers to improper fractions. (Multiply the denominator of the fraction by the whole number and add the numerator of the fraction)

Then keep the first number the same, change the division symbol to a multiplication symbol and use the reciprocal of the second number. (flip the numbers so that the denominator becomes the numerator and the numerator becomes the denominator.)

Then simply multiply across.

For example, if it's 4 1/3 divided by 1 1/3, multiply the denominator, 3, by the whole number. For 4 1/3, it would be 3*4 to get 12. Then add the numerator to get 13. 4 1/3 is then represented as 13/3. Do the same for 1 1/3 to get 4/3. Do the reciprocal to get 3/4. Then instead of dividing, do 13/3 times 3/4. Since the denominator of 13/3 and the numerator of 3/4 are the same, cross them out. You're left with 13/1 times 1/4. Multiply to get 13/4, or 3 1/4.

Tip: Use a website called Wolfram Alpha. Type in mixed numbers by using 4 (space) 1/3 (type times, don't put *) whatever number. wolframalpha.com

Answer:

It's actually an  enlargement  of the figure.

Step-by-step explanation:

Because if the figure originally was M' (-2,2), S' (4,2), V' (2, -2). And now the shape is M (-3, 3), S (6, 3), V ( 3, -3). This means that the Triangle got bigger.

The scale factor of the smaller shape inside of the bigger shape is 2 and the scale factor of the bigger shape is 3 making the bigger shape well bigger.

Peter is 2 years older than Winnie. Peter's age is 16 years less than seven times Winnie's age. The equations below model the re
GarryVolchara [31]
Given equations:
P=w+2
p=7w-16
Compare both equations
7w-16=w+2
Add 16 to both sides.
7w=w+18
Subtract w from both sides.
6w=18
Divide both sides by 6.
w=3, which is the age of Winnie.
Now Peter's age=3+2=5 years

Option A is the correct method to find the age of Peter and Winnie.

mina [271]

Answer:

105.876373581

Step-by-step explanation:

8.563 + 4.8292 = 13.3922

13.3922 × 9.183 = 122.9805726

122.9805726 ÷ 1.192 = 103.171621309

103.171621309 ÷ 1.192 = 86.5533735811

86.5533735811 + 19.323 = 105.876373581

Square of 9 less than a number is 3 less than the number
ale4655 [162]

Answer:Let the number be x, then (x - 9)^2 = x - 3

x^2 - 18x + 81 = x - 3

x^2 - 19x + 84 = 0

(x - 12)(x - 7) = 0

x = 12 or 7
