Answer:
The slope is -2/9
Step-by-step explanation:
9y + 2x = 54
Solve for y to get the equation in the form
y = mx+b where m is the slope and b is the y intercept
Subtract 2x from each side
9y + 2x -2x = -2x+54
9y = -2x+54
Divide by 9
9y/9 = -2x/9 + 54/9
y = -2/9 x +6
The slope is -2/9
Parallel lines have the same slope
Since there is 16 cups in a US gallon, and there is 7 days in a week. First, you would multiply 1.5 times 7 getting 10.5 cups. But since that is not enough cups to be a gallon the division equation would look like this, 10.5/16 = ?. You can simplify it down to 5.25/8. Then, you get your answer of 0.65625 gallons.
41) Circumference of a circle is 2*pi*radius, or pi*diameter.
Diameter given is 0.5cm, so circumference is 0.5pi, approximately 1.57cm.
It says scale is 1 cm to 2.5ft. Use dimensional analysis. You can multiply by 2.5ft / 1 cm because it equals 1, and multiplying by 1 doesn't change the value (just the units here).
1.57cm * 2.5ft
-------- = 3.925ft
1 cm
C) 4 feet
42) 6% of $900 is 0.06*$900, which is $54.
$900 is including tax, so subtract the tax ($54) to get the price before tax.
$900 - $54 = $846
A) $846
Answer:
The equation shows the commutative property of addition is 4 +3 = 3 + 4 .
Option (A) is correct.
Step-by-step explanation:
Commutative property of addition
The commutative property for addition states that
a + b = b + a .
Where a, b are any number.
thus
this above condition is satisfied by equation
4 + 3 = 3 + 4
7 = 7
Therefore Option (A) is correct.
