Answer:
This equation has Infinite solutions! or should i say that All real numbers are solutions.
Let me know if it is correct!
Step-by-step explanation:
a.
2(3x) - 5x = 4
6x - 5x = 4
x = 4
B. -5(x-4)+8x=29
-5x+20+8x=29
3x+20=29
3x=9
x=3
C. 2y=18+2(3-y)
2y=18+6-2y
2y=24-2y
4y=24
y=6
D. c = -b - 11
3c + 6 = 6b
3( -b - 11) +6 = 6b
-3b-33+6=6b
-3b-27=6b
-27=9b
3=b
Total number of fruits is 60 which is:
75% + 25% = 100%
hence 45 + 15 = 60
<h3>Breakdown of the model</h3>
Total number of fruits is 60
25% represents a quarter of the fruits which contains 12 pieces of fruits in each basket
number of fruit basket in 25% is calculated below:
the 25% of the fruit basket is 15 fruit baskets
75% represents three quarters of the fruits which contains 15 pieces of fruits in each basket.
number of fruit basket in 75% is calculated below:
the 75% of the fruit basket is 45 fruit baskets.
Total number of fruits is 60 which is:
75% + 25% = 100%
hence 45 + 15 = 60
