Answer:
Let's simplify step-by-step.
3−3/4x−1/4x−7
=3+ −3/4x+ −1/4x+ −7
Combine Like Terms:
=3+ −3/4x+ −1/4x+ −7
=(−3/4x+ −1/4x)+(3+ −7)
=−x+ −4
Answer:=−x−4
Step-by-step explanation:
answer:-4
The perimeter is (2 lengths) + (2 widths). Since the perimeter is 18 inches, (1 length) + (1 width) must add up to 9 inches.
If the length and the width must both be whole numbers, the only possible choices for the side lengths of this rectangle are:
1 x 8 in
2 x 7 in
3 x 6 in
4 x 5 in .
Answer:
$94
Step-by-step explanation:
Let the price of a bowl, a pan and a dish be $b, $p and $d respectively.
14b +9p +12d= 135 -----(1)
10b +6p +8d= 88 -----(2)
Subtracting equation (1) with equation (2):
14b +9p +12d -(10b +6p +8d)= 135 -88
Expand:
14b +9p +12d -10b -6p -8d= 47
4b +3p +4d= 47
Multiply both sides by 2:
8b +6p +8d= 47(2)
8b +6p +8d= 94
Thus, the price of 8 bowls, 6 pans and 8 dishes is $94.

Answer:
Option C. 2
Step-by-step explanation:
Let
x ----> the number of days
y ----> the internet charges in dollars
we have
This is a proportional relationship between the variables x and y
The slope of the linear function is equal to the constant of proportionality k
The unit rate is the same that the slope
so
The unit rate is $2 per day
therefore
The unit rate in the equation is 2
