Answer:
5.52 × 10^ 3
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
solve for x 7x-3=5x+5=
Answer:
x=4
Step-by-step explanation:
7x-3=5x+5
2x-3=5
2x=8
x=4
The value of x in the expression 7x-3=5x+5 is 4
Given
7x-3=5x+5
Here,
The equation is linear in variable x .
7x-3=5x+5
7x - 5x - 3 = 5
2x-3=5
2x = 5 + 3
2x=8
x = 8/2
x=4
Thus the value of x is 4 .

Chance wants to wish his cousin a happy birthday at 9:00am CST. Chance lives in Texas and his cousin lives in Ohio. What time will it be at his cousins's house when Chance calls to say happy birthday?
Answer:
10:00 am EST in Ohio
Step-by-step explanation:
Using the 50 States Time zones attached in the image below.
Chance who lives in Texas has a Time zone of CST (central standard time), while his cousin who lives in Ohio has a Time zone of EST(eastern standard time).
So if it is 5 pm in CST, it will be 6 pm in EST.
Given that;
Chance wants to wish his cousin in Ohio at 9:00 am CST, then the time it will be at his cousin's house when Chance calls to say happy birthday will be:
9:00 am + 1 = 10 :00 am EST in Ohio

MUST BE CORRECT OR REPORTING!
Answer: 17
Step-by-step explanation:
Each side has one line on it indicating each side is equal therefore 5y-3= 4y+1. Once you put them equal to each other you solve for y. You start by isolating the variable by inverse operations so you add 3 to both sides which leaves 5y=4y+4 and then you subtract 4y from both sides leaving y=4. Now that you found the value of y you input that value into one of the expression for one of the sides and solve. 5(4)-3= 17

The dew point in degrees Fahrenheit can be calculated with the formula DP = T (100 - RH), where DP is
the dew point, T is the dry-bulb temperature, and RH is the relative humidity. Which of these is the equation
solved for RH?
RH = 100 -
(T-DP)
RH = 100 – 2 (DP-1)
RH = 100 – (DP-1)
RH = 100 – 25 (T-DP)
Answer:
B
Step-by-step explanation:
I took that same test and i didthe practice test. Believe me.
The equation that can be used to solve for RH is 25/9(DP-T) - 100
Given the formula for the dew point in degrees, Fahrenheit expressed as
DP = T - 9/25(100 - RH)To solve for the value of RH, we will make RH the subject of the formula;
DP = T - 9/25(100 - RH)Subtract T from both sides:
DP - T = 9/25(100 - RH)Multiply both sides by 25
25(DP - T) = 9(100 - RH)
25(DP - T) = 900 - 9RH
25(DP - T) - 900 = 9RH
RH = 25/9(DP-T) - 100
Hence the equation that can be used to solve for RH is 25/9(DP-T) - 100

In 1998, Journeys sold 15 million pairs of Vans across the
U.S. In 2008, Journeys sold 45 million pairs of Vans. What
was the average rate of change in shoe sales for the store?
Answer:
3 million/yearStep-by-step explanation:
Average rate of change is the slope in same interval:
(45 million - 15 million)/(2008 - 1998) years=30 million / 10 years =3 million/yearIn 1998, Journeys sold 15 million pairs of Vans.
In 2008, Journeys sold 45 million pairs of Vans.
To Find:The average rate of change in show sales for the store.
Formula:Final year : 2008
Initial year : 1998
Final sale : 45 million
Initial sale : 15 million
Average sales = Final sale - Initial sale / Final year - Initial year
Explanation:Average sales = 45 million - 15 million / 2008 - 1998
Average sales = 30 million / 10 years
Average sales = 3 million / 1 year
Answer:The average rate of change in show sales for the store is 3 million per year.

Solve the problem below by finding a common denominator.
5/6-2/5
Answer:
I know how to this in one of two ways and I'm not sure if they're correct but anything to help.
5/6-2/5 would get you 1/3 because if you cross multiply and cross out factors that can go into each you cant pretty much get that answer. ( i think)
or
the common denominator would be 30 multiply 5 by 5 and 2 by 6. 25-12 is 13. How I was taught was find a number that both denominators can go into then multiply by that number. So 6*5= 30 so you would multiply 5 by 5 to get 25.
Hope I explained this well, I don't really think so.
