Answer:
$315
Step-by-step explanation:
1.75 x 100 = $175
3.50 x 40 =$140
175 + 140 = $315
Answer/Step-by-step explanation:
84 = L x w
84 = 84 x 1
84 = 42 x 2
84 = 28 x 3
84 = 21 x 4
84 = 14 x 6
84 = 12 x 7
Answer:
C) 14
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
Multiply -2 to both sides of the equation. Note that, when multiplying two negative numbers, your outcome will be positive:
(-2)((-1/2)x) = (-7)(-2)
x = -7 * -2
x = 14
C) 14 is your answer.

Step-by-step explanation:
5x+3y = 6
5x = 6 - 3y
5x = 3(2-y)
5x/3 = 2 - y
y = 2 - (5x/3)
slope = x coefficient.
= - 5/3
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
new slope = 3/5
the equation formula
y = mx + b
m = new slope = 3/5
y = (3x/5) + b
From the point given (3 , -1 )
x = 3.
y = -1
-1 = (9/5) + b
b =( -5/5) - (9/5)
b = - 14 / 5
