zzz [600]

when you solve an inequality the result is an interval when you solve an equation is a number or set ex x^2=25 x=-+5 the result is finite numbers

when you multimply an equation the sign inverses but when you solve an equation there is nothing to change

similiarities

you can add and subtract numbers from both sides

diving and multypling the equation or inequation by a positive numeber as i said in the beggining by multypling or dividing with a negative number the equation s sign inverses ex >= becomes <=

Raymond developed an app for smartphones. During the first week, he had 7,040 downloads from girls and 3 times as many downloads

myrzilka [38]

Answer:

The correct calculation is D. 7,040 × 3, then 21,120 ÷ 8

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Number of downloads from girls = 7,040

Number of downloads from boys = 3 times as many

Number of boys who downloaded and paid the full version = 1 out of 8

2. Which calculation yields the number of boys who bought the full version of the app?

Number of downloads from boys = 3 * 7,040

Number of downloads from boys = 21,120

Number of boys who downloaded and paid the full version = 21,120/8 = 2,640

The correct calculation is D. 7,040 × 3, then 21,120 ÷ 8

1) the degrees of a six-sided figure is 720 degrees
so x= 720-632 (given degrees in all)
x=88 degrees

2) the degrees of a five-sided figure is 540
so x= 540-441
x=99

then 180-99=81
so, y=81
