Answer:
A. -68
B. 37
C. -61
D. 171
Step-by-step explanation:
Rule for A, B, D: 2 negatives is the same as addition
(how I did C: add them together then add the negative)
3.5z=2.25z-4.25+6.25
1.25z=2
z=1.6. As a result, this equation have one solution. Hope it help!
Put the number over each the total that was added then, divide the bottom number to into the top number
A number that cannot be expressed that way is irrational. For example, one third in decimal form is 0.33333333333333 (the threes go on forever). However, one third can be express as 1 divided by 3, and since 1 and 3 are both integers, one third is a rational number.
hope it helps!
