Answer:
3%
Step-by-step explanation:
105 = 700 x r x 5
r = 105 / ( 700 × 5 ) = 0.03
r = 0.03
0.03 in percent is 3%
No, the expressions –0.5(3x 5) and –1.5x 2.5 are not equivalent.
Using the distributive property to expand the first expression, you would get -1.5x - 2.5. Since the constant term does not have the same sign as the second expression, the two expressions are not equivalent.
Also, if you substitute in a value for x and evaluate each expression, the values will not be equal.

Answer:
a c d
Step-by-step explanation:
a c d are quadratic equation expect "b"
For this problem, we can move all the X's to one side and all the regular numbers to the other.
7x comes over and become -7x
10 goes over and becomes -10.
5x+7x-7x=-3-10+13+12.
-3-10=-13, which cancels out the positive 13.
-7x+7x=0 which cancels each other out.
Now, 5x=12
Divide each side by 5.
x=2.4 <--- final answer.
