Answer:
32
Step-by-step explanation:
We are given the expression:
and asked to evaluate the expression.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
Solve inside the parentheses first. Subtract 37 from 13.
⇒ 13-37= -24
Next, multiply -8 and -24.
⇒ -8*-24= 192
Finally. divide 192 by 6.
⇒ 192/6 = 32
When evaluated, the expression -8(13-37)/6 is equal to 32.
50.5 and 53.5
104-3=101 divided by 2=50.5 50.5+3 equals 53.5. 50.5+53.5=104
360
400 - 40 = 360

If p(x) is a function, then a real-world example might be
The amount of fish food, in grams required for the giant koi fish in the pond can be represented by the function
. If there are 50 fish, how many grams of fish food will you need?
X + 5y = 1 . . . . (1)
8x - 2y = 3 . . . .(2)
Solution 1.
From (1), x = 1 - 5y
substituting for x in (2), we have:
8(1 - 5y) - 2y = 3
8 - 40y - 2y = 3
8 - 42y = 3
42y = 5
y = 5/42
x = 1 - 5(5/42) = 1 - 25/42 = 17/42.
Solution 2.
Multiply (1) by 8, to get:
8x + 40y = 8 . . . . . (3)
(3) - (2) = 40y - (-2y) = 8 - 3
42y = 5
y = 5/42
substitute for y into (3), to get:
8x + 40(5/42) = 8
8x + 100/21 = 8
8x = 8 - 100/21 = 68/21
x = (68/21)/8 = 17/42
