Answer:
The first our to the second hour
Answer:
see below
Step-by-step explanation: 5 27 7 16
area = 1/2 bh
height of a triangle is 7 ft more than its base
base = b
height = b + 7
area = 30
area = 1/2 b(h)
30 = 1/2 b(b + 7)
30 = 0.5(b²+ 7b)
30 = 1/2 b²+ 3.5b solve for b
1/2 b²+ 3.5b = 30
1/2 b²+ 3.5b - 30 = 0
b²+ 7b - 60 = 0 factor
(b +12)(b - 5) = 0 when b = -12 or 5 base length can't be negative
b = base = 5
area = 1/2 bh 1/2×2(9) = 9
area = 1/2 bh 1/2×5(12) = 60
area = 1/2 bh 1/2×9(16) = 56
area = 1/2 bh 1/2×12(19) = 114
B. the weight of the objects inside the box
Yeah they looks pretty similar
The given statement 5x=4y=12 and x+6y=5 is true.
<u>Step-by-step explanation:</u>
The question comes from linear equations in two variables.
Here, two unknown variables represent a certain situation and their value can be obtained by solving both the given equations.
The cost of cookie is represented by the variable x and cost of doughnuts can be represented by the variable y.
The coefficient of each variable in the equation represent the quantity or the number of units of each baked good.
On comparing the given equations from the data provided in the question, the statement can be stated as true.
