Rick started with 10/10 of the grapes because he had all of them at the start.
Then he gave 2/10 and 4/10 of the grapes away.
10/10 - 2/10 - 4/10 = 4/10 = 2/5 left
answer: Rick had 2/5 of the grapes left.
Unit fractions are fractions with a 1 as the numerator(number on top)
so 3/8 equals 1/8+1/8+1/8

Answer:
cos 30° =767.6/hypotenus
(make h the subject of the formular)
h = 767.6/cos 30°
h =767.6/0.154
h =4,985
approximately 5,000
The work inside parentheses cannot be carried out as shown, so the next approach to consider is multiplying the expressions inside the parentheses by -5 and 5 respectively:
-5 + 25x - 40x - 10 = -4x - 8x (Are you sure it's really "-4x - 8x"?)
Combining the x-terms:
-5 - 15x - 10 = -12x
Combining all like terms: -15 = 3x, so that x = -5 (answer)
