Answer:
2⅝
Step-by-step explanation:
You must convert each fraction to a <em>common denominator</em>.
The <em>least common multiple</em> of 2, 4, and 8 is 8.
1/4 +3/8 + 1/2 + 5/8 + 7/8 Convert to a common denominator
= 2/8 + 3/8 + 4/8 + 5/8 + 7/8
= (2 + 3 + 4 + 5 + 7)/8
= 21/8 Convert to a mixed number
= (16 + 5)/8
= 2 + ⅝
= 2⅝
Answer:
this the answer to the question I understand
Answer:
Step-by-step explanation:
let : x The length and y the width you have this system :
xy =60....(1)
x = y+10...(2)
put the value for x in (1): (y+10)y =60
the quadratic equation is : y² +10y - 60 = 0
Δ =b² - 4ac a = 1 b= 10 c= - 60
Δ =10² - 4(1)(-60) = 324 =18²
y 1 = (-10-18)/2 negatif...... refused
y 2 = (-10+18)/2 =4
the width is 4
The answer would be 219.3 (:
