Positive? So are these fractions negative? But here's my answer, 3/8 + 1/4 = 5/8.
Answer:
30 yellow straws and 45 red straws
30:45
Step-by-step explanation:
Make a ratio:
2:3, 2 being the yellow straw and 3 being the red straws
They are now asking how many red if there are 30 yellow straws
2:3 = 30:x
You could either cross multiply or simply do 30 ÷ 2 = 15 then 15 × 3 = 45. Your answer is 45
<u>Cross </u><u>multiplying</u>
2x = 90
90 ÷ 2 = 45
Hello There!
13n - 13 = 11n + 25
Plus 13 to both sides:
13n - 13 + 13 = 11n + 25 + 13
Simplify it:
13n = 11n + 38
Subtract 11n from both sides:
13n - 11n = 11n + 38 - 11n
Simplify:
2n = 38
Divide by 2:
2n/2 = 38/2
Simplify it:
n = 19
Hope This Helps You!
Good Luck :)
