Answer the question below:
Answers
Answer:
C
Step-by-step explanation:
I would first try to get that fraction into x/100 because 100 is the easiest to work with.
In order to get from 40 to 100, you multiply by 2.5
So we should multiply 29 by 2.5 also to make it evened out.
29 x 2.5 = 72.5
72.5/100
Now we will move the decimal two places to the left on both sides because 100. is the same as 100
72.5/100. turns into .725/1
The closest thing to .725 is .7
Answer:
B 0.6
Step-by-step explanation:
29/40=0.725
0.725 rounded down is 6
Last month, Belinda worked 160 hours at a rate of $10.00 per hour. If her employer retains 9% of her gross salary, is $1,500 a reasonable estimate of her net salary?
A. Yes, because her salary will be a bit more than 1600 - 160 = 1440.
B. No, because retaining 10% of her salary would leave her with about $1,350.
C. Yes, because $1,500 is close to 1600 - (10 x 9) = 1510.
D. No, because $1,300 is a better estimate.
Answers
Answer:
Its A
Step-by-step explanation
for $10.00 per hour for 160 hours, Belinda would make $1600. But her employer takes 9% of it. we can round 9% to 10%. 10% of $1600 is $160.
so A. Yes, because her salary will be a bit more than $1600-160=1440
Her whole monthly salary is $160x10= $1600
9% of 1600 = 1600 x 9/100 = $144
1600-144= $1456
1456 > 1600 - 160 = 1440

Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8
Answers
The correct answer is (D) -2x - 8.
To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:
-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3
Then we can simplify using the properties of multiplication and division:
-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3
Finally, we can combine like terms:
-2x - 5 - 3 = -2x - 8
The correct answer is therefore (D) -2x - 8.✅
