Mary lou has 2 more nickels than pennies, and she has 30 coins all together. use x for the number of pennies.
a) 2(x + 2) = 30
b) x + (x + 2) = 30
c) 2x + 30 = 5
d) x + 2 = 30

If 3x+8=3x+8 is it one solution or no solution

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
