Answer:
= 4
Step-by-step explanation:
sqrt 15 = 3.872
to approximate to the nearest whole number (integer), you take the first decimal number which is 8, since 8 is greater than 5, you will add one(1) to the whole number which is 3 to make it 4.
I would try using Photomath or Desmos both great graphing apps!
Answer:
I believe the answer is B or C, but i pretty sure it is B.
Divide 12 by 4
→ 12 / 4 = 3
you can know Audrey take 3 units of time to hang 12 streamers
then how many streamers can Megan hang in 3 units of time?
Just multiply the number of streamers that Megan can hang in a unit of time by 3
→ 6 * 3 = 18
So the answer is 18
Answer:
9
Step-by-step explanation:
Let us represent
Low priced = x
High priced = y
An online store sells two types of speaker docks for smartphones. The higher-priced speaker dock sells for $170 and the lower-priced speaker dock sells for $90. Combined sales totaled $4,770.
170x + 90y = $4770
Last week the store sold four times as many lower-priced speaker docks as higher-priced speaker docks.
4x = y
Substitute 4x for y
170x + 90y = $4770
170x + 90(4x) = $4770
170x + 360x = $4770
530x = $4770
x = 4770/530
x = 9
The number of lower-priced speaker docks it sold was 9
