Answer:
10. 27 shoes
11. No, both are 18, they are equal
12. 96 dogs
13. 125 students
14. 600 students
15. 50 tulips
16. 70 cars
17. Rory divided the percentage by the number (#/%=#)
Step-by-step explanation:
To find a percentage of somethin, multiply the number by the percent
(54 shoes x 50% (0.50) = 27 shoes)
To find the original number, divide the new number by the percentage
(25 students/20% (0.20) = 125 students)
<span>We have to find the value of x if the measures of the angles of a triangle are: 2 x, 3 x and 4 x. We know that the sum of the measures of the angles of a triangle is 180 degrees. A + B + C = 180. Here we have: A = 2 x, B = 3 x and C = 4 x; 2 x + 3 x + 4 x = 180; 9 x = 180; x = 180 : 9. Answer: x = 20 degrees.</span>
The measure of the supplementary angle is 148 degrees.
Hope this helps!
First you would have to turn the mixed number into a improper fraction. to do that you would have to multiply the denominator by the 1 (which is the whole number) to get 3*1=3 then you would have to add the numerator to get 3+2=5. now you have an improper fraction which is now 5/3. you always keep the denominator the same. next you have to multiply the two fractions you now have. which is 5 over 3 and 3 over 4 . all you have to do is multiply across to get 5*3=15 on the top and 3*4=12 on the bottom. so your new fraction you have is 15/12. that's an improper fraction so you would have to divide 12 by 15. you know 12 goes into 15 one time with a remainder of 3. so now you have 1 3/12 as your answer. but your not done yet. now you have to simplify your answer by dividing the numerator and denominator by 3 to get 3/3=1 and 12/3=4, you final answer should be 1 1/4 .
2x+8+6=22
2x+14-14=22-14
2x = 8
2x/2 = 8/2
x = 4
Check your work
2(4+4)+6=22
2(8)+6=22
16+6=22
22=22
