Answer: See explanation
Step-by-step explanation:
We are informed that we should write a equation that represents the expression "Ali writes the expression "half of the sum of $9 and a number.".
Let the number be represented by x. The first equation based on the information given will be:
= 1/2(9 + x)
The second equation will be:
= (9 + x)/2
= 4.5 + 0.5x
Answer:
She put decimal in the wrong place.
Step-by-step explanation:
Consider the provided sentence.
9 × 0.989 = 89.01
Estimate the number 0.989 to nearest natural number.
The estimation of the number 0.989 to the nearest natural number is 1.
Now multiply 9 with 1.
9 × 1 = 9
Hence, the product should be less than 9.
Since the product of 9 and 0.989 is 89.01 which is greater than 9.
Thus, we can concluded that Jen's answer is wrong.
She put decimal in the wrong place, the required product must be 8.901
Here, you can observe that the number 8.901 is less than 9 and estimation of the number to the nearest natural number is 9.
900/1200 = 0.75
75%
The first year was 75% of the second year
Answer: r < 389
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
Rushawn's possible finishing times (r) must be less (<) than Josie's finishing time (329) plus 60 seconds.
Mathematically speaking:
r < 329+60
r < 389
So, the correct option is the last one.
Feel free to ask for more if needed or if you did not understand something.
12+6n=30
6n=18
n=3
So the number would be three
