Answer:
The correct answer is 2. An angle and the two sides collinear with the angles race are congruent to the corresponding parts of another triangle.
Step-by-step explanation:
The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
An included angle is an angle formed by two given sides.
So, the correct answer is 2. An angle and the two sides collinear with the angles race are congruent to the corresponding parts of another triangle.
A dime is worth 10 cents and a quarter is worth 25 cents.
Let D be the number of dimes and Q be the number of quarters.
Since the total amount of coins in the pocket is 32, then:
On the other hand, the total value of D dimes is 10D, while the total value of Q dimes is 25Q. Then, the total value of D dimes and Q cuarters is 10D+25Q, which must be equal to 545. Then:
Notice that we have found a 2x2 system of equations:
Solve the system using the substitution method. To do so, isolate D from the first equation and replace the expression for D into the second equation to obtain a single equation in terms of Q:
Replace back Q=15 into the expression for D to find the amount of dimes:
Therefore, the amount of dimes that the man has is 17.
Lets say x = 89.99 and y = 56.49
P% * x = y
P% = y/x
56.49/89.99 = 0.6277
0.6277 * 100 = 62.77
But because we are looking for how much off the sale is:
100% - 62.77%
= 37.23%
The sale price is 37.23% off.
Left and right side are exactly same, therefore "<span>the equation is true for any value of x.</span>"
