Answer:
96 units^2
Step-by-step explanation:
area of a triangle A=bxh/2
substitute b with 8 and h with 24
A=8x24/2
multiply
A=193/2
the divide
A=96
Answer:
I dont know what the answer is exactly
Let the cost of 1 notebook be x and the cost of 1 binder be y.
4 notebooks and 3 binders would cost 23.5
Therefore, 4x + 3y = 23.5 (1)
7 notebooks and 6 binders would cost 44.5
Therefore, 7x + 6y = 44.5 (2)
Multiply the first equation by 2.
8x + 6y = 47 (3)
(3) - (2) gives
x = 2.5
Substitute the value of x in (1), we get,
4(2.5) + 3y = 23.5
10 + 3y = 23.5
3y = 23.5 - 10
3y = 13.5
y = 13.5/3
y = 4.5
Hence, cost of 5 notebooks and 3 binders is:
5x + 3y = 5(2.5) + 3(4.5)
= 12.5 + 13.5
= 26
Hence, cost of 5 notebooks and 3 binders is $26.
3y=−4x+2
y = -4x/3 + 2/3
y = 3x/4 + 2/3
so the slope is 3/4 remember that perpendicular slope is just the opposite reciprocal of the original slope given.
