10/12 can be reduced to 5/6
Answer:
its the third option
Step-by-step explanation:
the one with 2 rings on the second longest angle 2 lines on longest side one side and 1 line on the shortest side
All the described pairs of triangles that are reflected, rotated, or both, can be proven congruent by the SAS postulate because such rigid transformations preserve the congruency of sides and angles.
To determine which pair of triangles can be proven congruent by the SAS (Side-Angle-Side) postulate, we look for two sides of a triangle and the included angle that are congruent to two sides and the included angle of another triangle. When a triangle is reflected across a line, rotated 90 degrees, or both reflected and rotated, it maintains its size and shape, thus the corresponding sides and angles remain congruent.
A reflection or rotation (including a combination of both) is a type of rigid transformation which preserves the size and shape of figures. Hence, all the given pairs of triangles can be proven congruent to the original triangle through the SAS postulate, as rigid transformations do not alter the congruity of sides and included angles.

Answer:
7
Step-by-step explanation:
x = 2y-1
2x = 4y-2
4y - 2 = 3y + 2
y = 4
x = 2(4) - 1
= 7

I did the elimination method and it said 4 nickels which in turn gives me 52 pennies.
There are 32 pennies and 24 nickels in jar
Solution:
Let "n" be the number of nickels
Let "p" be the number of pennies
1 penny = 0.01 dollar
1 nickel = 0.05 dollar
There are 56 coins in the jar in all
Therefore,
number of nickels + number of pennies = 56
n + p = 56 ----------- eqn 1
The total value of coins is $ 1.52
Thus we frame a equation as:
number of nickels x 0.05 + number of pennies x 0.01 = 1.52
0.05n + 0.01p = 1.52 -------- eqn 2
Let us solve eqn 1 and eqn 2
From eqn 1,
n = 56 - p ------ eqn 3
Substitute eqn 3 in eqn 2
0.05(56 - p) + 0.01p = 1.52
2.8 - 0.05p + 0.01p = 1.52
0.04p = 2.8 - 1.52
0.04p = 1.28
Divide both sides by 0.04
p = 32
Substitute p = 32 in eqn 3
n = 56 - 32
n = 24
Thus there are 32 pennies and 24 nickels in jar
