Answer:
b = 6 units
Step-by-step explanation:
Area = 1/2bh
8 = 1/2(b)(8/3)
divide both sides by 1/2
16 = b(8/3)
multiply both sides by 3
48 = 8b
divide both sides by 8
b = 6 units
For your boxes:
1/2 x b/1 x 8/3 = 8/1
b/1 x 8/3 = 16/1
8b/3 / 8 = 2/1
b/3 x 3 = 6
The answer is A because if X represents the # of packages sold on Monday, then Tuesday can be represented by x+4 and Wednesday by x+6. Add the three expressions to get 3x+10=28, subtract 10 from both sides. 3x=28, divide by 3 and get x=6
(x - 5)/4 = (x + 1)/3
3(x - 5) = 4(x + 1)
3x - 15 = 4x + 4
4x - 3x = -15 - 4
x = -19
Answer: Van = 198 students
bus = 672 students
Step-by-step explanation:
Let x represent the number of students in the vans and y represent the number of students in the buses, then from the first statement , we have
11x + 4y = 289 ................. equation 1
From the second statement, we also have
7x + 12y = 581 ............... equation 2
Combining the two equations together and solving simultaneously , we have
x = 11 and y = 42
therefore the number of students vans can carry will be'
11x + 7x
= 11(11) + 7 (11)
= 121 + 77
= 198
The number of students buses will carry will be
4y + 12y
= 4(42) + 12(42)
= 168 + 504
= 672
