Answer:</h2>
f(t) is the amount of substance remaining.
f(t) = 6.6 × 12 × 28.
<u>Correct choice</u> - [D] f(t) = 6.6(12)28.
Answer:30x=840 30 represents the number of days and x represents miles per day
b)yes because 30 (28)= 840 miles
c)yes because 30(40)= 1200 miles and the question said at least 840 so it can be more
d)30(11)=330
e) 10,800- 4,015 miles =6785 miles will be saved
Step-by-step explanation:
Answer:
5 x 2 inside the parenthesis
Step-by-step explanation:
We need an order of operations to ensure we always arrive at the correct answer. It gives us a consistent way to work with numbers. We use the mnemonic device like PEMDAS to remember the correct order.
P-parenthesis
E-exponents
M-multiplication
D-division
A-add
S-subtract.
We apply them left to right doing inner operations before outer operations.
There fore our first step is in the parenthesis and multiplication because it is the inner most operations. 5 x 2 inside the parenthesis.
A,B,C,D,E
AB, AC, AD, AE

Answer:
5x+4y=85-
Slope = -2.500/2.000 = -1.250
x-intercept = 85/5 = 17
y-intercept = 85/4 = 21.25000
2x+3y=41-
Slope = -1.333/2.000 = -0.667
x-intercept = 41/2 = 20.50000
y-intercept = 41/3 = 13.66667
