Answer:
x = —2/5
Step-by-step explanation:
1/4x=-5/8
Cross multiply to express in linear form
4x x —5 = 8 x 1
—20x = 8
Divide both side by the coefficient of x i.e —20
x = 8/—20
Reduce to the lowest term
x = —2/5
Distance biked before lunch = 1
km (the number is written in mixed fraction)
⇒ Distance biked before lunch = 
Distance biked after lunch = 6
km (the number is written in mixed fraction)
⇒ Distance biked after lunch = 
We need to determine how much farther does Hallie bike after lunch than before lunch
Extra distance biked after lunch vs. before lunch =
- 
⇒ Extra distance biked after lunch vs. before lunch = 
⇒ Extra distance biked after lunch vs. before lunch = 
⇒ Extra distance biked after lunch vs. before lunch = 4
(in mixed fraction)
Hence, Hallie biked 4
km extra after lunch vs. before lunch.
11+6=17 17÷2= 8.5 hours so the answer would be 4:50pm. Maybe
Answer: 1 ⁸/₂₁ litres
Step-by-step explanation:
First find a common multiple to enable you add them up:
= 21
21 will be the denominator.
Multiply each numerator by the number you get when you divide 21 by the denominator.
= 21/3 = 7
= 7 * 2 = 14
= 21/7 = 3
= 3 * 5
= 15
