1. Selena has to walk to school and from school. That means that each day, she walks the distance from her house to the school twice. If she walks 2/3 in a day, the distance must be half of that, or 1/3. 2. 3 batches = 3/4 cup. Divide each side by 3. 1 batch = 1/4 cup. 3. 5 eighths minus 1 eighth = 4 eighths. Since we have the same bottom number, we don't need to do anything special. This problem is just the same as something like 5 apples - 1 apple. 4. First, let's convert 6 into thirds. 6 × 3 = 18 Therefore, 6 = 18/3.
Add 6 and 2/3. 18/3 + 2/3 20/3 5. To be a composite number, a number needs to be divisible by something besides 1 or itself. Check your divisibility rules... 39 is divisible by 3 (39 ÷ 3 = 13), so this could be his house number.
6. 12 cupcakes - 9 chocolate = 3 vanilla. 3 vanilla cupcakes out of 12. (3/12) We can simplify this fraction. 3 and 12 are both divisible by 3. 3/12 = 3÷3 / 12÷3 = 1/4
number one is 1/3 because 1/2 of 2/3 is 1/3
What is 91/72 simplified?
Answers
91/72 cannot be simplified anymore, but if you divide (commonly on a calculator), you can achieve the decimal form of the fraction which is, 1.2639 OR, 1 with a remainder of 19.
If you want the mixed number form, you will have to divide the numerator by the denominator. In this case, just use the decimal form or, 1 with a remainder of 19. Your mixed number would be 1 19/72.
85% of 40 e-mails it's to hard for me
Answers
85% of 40 e-mails is 34
85% of 40
If its percent just take it upon 100 and multiply it by the number :)
85/100 × 40 = 85×40/100 = 85×2/5 = 170/5 = 34
In triangle XYZ, the length of side XY is 26 mm and the length of side YZ is 37 mm. Which of the following could be the length of side XZ?A. 68 mm B. 44 mm C. 9 mm D. 65 mm
Answers
A). 68 D). 65 If the third side was either of these, then (26 + 37) = 63 could not reach between the ends of it. A triangle could not be formed.
C). 9 If the third side was this, then it could not reach between the ends of the 26 and the 37 . . . they're always AT LEAST 11 mm apart.
B). 44 This is the ONLY one on the list that can make a triangle along with 26 and 37.
To solve this, you can use the triangle inequality theorem: Side 1 + Side 2 must be greater than Side 3. So, plug in 26 for Side 1 and 37 for Side 2, add them together, and see which number is smaller than 27 + 37.
Can the sum of two mixed numbers be equal to two? Explain why or why not.
Answers
No because to make it a mixed number you need a whole number involved and a fraction. The smallest well whole number is one and one plus one is two. Therefore no even having room for the fractions you needed to add up as well. Sorry if that was confusing I tried to explain it my best. Hope I helped.
Answer:
Yes but one of thw mixed number must be negative

Which expressions would complete this equation so that it has infinitely many solutions?8 + 2(8x – 6) = Choose exactly two answers that are correct A. 2(4x + 7) B. 9x – 10 C. 16x – 4 D. 4(4x – 1)
Answers
A) 8 + 2(8x - 6) = 2(4x + 7) is B) 8 + 2(8x - 6) = 9x - 10 is C) 8 + 2(8x - 6) = 16x - 4 has infinite solutions. D) 8 + 2(8x - 6) = 4(4x - 1) has infinite solutions.
