Multiply both sides by 7. w=<span>105</span>
Start, the first MAD is 2.5 go right, the second MAD is 3 MAD diagonal down, third is 6 go left. Fourth is MAD 9 straight down 2.8, Fifth diagonal up, 6th right MAD 1.5 =Finish
Equivalent fractions are those fractions that when simplified, are the same. They reduce to the same fraction in their simplest form.
For example, 12/15 and 24 /30 are equivalent fractions. They both reduce to 3/5 in their simplest form.
Least common denominator: it is the lowest number you can use in the denominator to create a set of equivalent fractions that all have the same denominator.
For example, if you have 3/5 + 1/4 and want to add them, you need to get a common denominator
3/5 = 6/10 = 9/15=12/20
1/4 =2/8=3/12 =4/16=5/20
We can use equivalent fractions to help us find the common denominator of 20
replace 3/5 with 12/20 and 1/4 with 5/20
3/5 + 1/4 = 12/20 + 5/20 = 17/20
Circumference: 18.84 m
Area: 28.26
Explanation
For circumference, use the formula *d, where d=the diameter(the radius times 2).
For area, use the formula , where r=the radius. Make sure to square the radius first before multiplying by pi!
A good way to remember these formulas is Cherry(circumference) Pi() is Delicious(diameter) and Apple(area) ("are too")
3, 5, and 6 are incorrect.
In number 3, you have all the steps correct, except for the last one. Instead of adding 19 to 25, you would multiply it, because there is no addition sign in between the absolute value sign and 5^2. Thus making the answer 475.
In number 5, you first square -2. -2 * -2 ( or -2^2) = 4. Next, you square 3. 3 * 3 (3^2) is 9. Then, you subtract 9 from 4 to get -5. The absolute value of -5 is 5, making 5 the answer. Absolute value is kind of like the distance from zero, for instance -5 is 5 units away from 0 and the absolute value can never be a negative number. Thus making 5 the answer.
In number 6, you first solve the parenthesis. 2 - 3 = -1 and -1 * -1 (-1^2) is 1. Next, you square -3. -3 * -3 (-3^2) = 9. Then, you subtract 1 from 9 to get 8. The absolute value of 8, is 8. Finally, multiply -4 and 8 to get -32. Thus meaning -32 is the answer.
I hope this helps!
