Answer:
2.
Step-by-step explanation:
We have been given an expression
and we are asked to find equivalent expression to our given expression.
Using fraction rule
we can write our expression as:
.
Upon dividing 10 by 5 we will get,
Upon using exponent property for quotient
we will get,
Therefore, our expression simplifies as
and 2nd option is the correct choice.
Answer:
40.35
Step-by-step explanation:
First find the discount
97 * 60%
97 *.6 = 58.2
Subtract the discount to find the new price
97-58.20 =38.80
Next find the tax
38.80 * 4%
38.80 * .04
1.55
We add the tax to the sales price
38.8+1.55
40.35
Answer: X = 50
Step-by-step explanation: We shall first solve for X in the algebraic expression as follows ;
(X + 10) + (2X + 20) = 180
By removing brackets and collecting like terms we now have
X + 2X + 10 + 20 = 180
3X + 30 = 180
Subtract 30 from both sides of the equation
3X = 150
X = 50
If X has been identified as equal to 50, then the two angles given shall be
Angle 1 = X + 10
Angle 1 = 50 + 10
Angle 1 = 60
Also
Angle 2= 2X + 20
Angle 2 = 2(50) + 20
Angle 2 = 100 + 20
Angle 2 = 120
One of the properties of a parallelogram is, “Opposite angles are congruent.”
The other two angles would also measure 60 and 120, and the sum of all the interior angles shall be;
60 + 120 + 60 + 120 = 360
360 = 360.
