Step 2: Four halves times x minus ten plus ten equals thirty plus ten Reason 2: Addition Property of Equality
Step 3: Four halves times x equals forty Reason 3: Simplify
Step 4: Four halves times x times two fourths equals forty times two fourths Reason 4: Division Property of Equality
Step 5: x = 20 Reason 5: Simplify

69

step-by-step explanation:

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

if you need just tell me and i will come to the rescue.

step-by-step explanation:

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
