for every 15 students who run track there are 7 students who play baseball there are 112 more students who run track than play basball
Answer:
How many students run TRACK? 210
How many students play BASEBALL? 98
15*14= 210 and 7*14 = 98, 210 - 98 = 112
Answer:
There are 210 students who run track and 98 students who play baseball.
Step-by-step explanation:
15x= Students who run track
7x= Students who play baseball
15x - 7x = 112 (*combine like terms)
8x = 112 (*divide 112 by 8)
X = 14 (*now plug X into both equations stated earlier)
15x = 15 x 14 = 210 (Number of students who run track
7x = 7 x 14 = 98 (Number of students who play baseball)
What is the solution to the following equation? (1 point) 8(2x − 10) + 18 = 4x + 22 4 5 7 8
Answer:
x=7
Step-by-step explanation:
8(2x-10)+18=4x+22
distribute the 8
16x-80+18=4x+22
simplify
16x-62=4x+22
ads 62 to each side
16x=4x+84
subtract 4x from each side
12x=84
divide each side by 12
x=7

how do you write 5,520 in scientific notations
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.

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
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.

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

Tony's family owns a Chihuahua that gets 3 dog bones each day for doing tricks. Tony has a total of
16 dog bones he must give his dog for doing tricks. Write an algebraic equation that describes the
relationship between the number of days (d) and the number of bones remaining (b).
9514 1404 393
Answer:
b = 16 -3d
Step-by-step explanation:
If Tony gives 3 dog bones per day, then he uses 3d dog bones for d days. The number remaining will be this value subtracted from the original number:
b = 16 -3d
Find the area of the rectangle and the triangle independently. What is the ratio comparing the area of the triangle to the area of the rectangle? (Must be in Reduced Form)

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.

-9 (c + 7) = -13c +7
What value of c makes the equation true? Enter the answer in the box.
Answer:
c=17,5Step-by-step explanation:
-9(c+7) = -13c+7
<=> -9c - 63 = -13c+7
<=> -9c + 13c = 7+63
<=> 4c = 70
<=> c = 70/4 = 35/2 = 17,5
CHECK THE ANSWER:-9(c+7) = -13c+7
-9(17,5+7) = -13×17,5+7
-220,5 = -220,5
