fgiga [73]3 years ago
7 0

Answer:

21

Step-by-step explanation:

8x+y, when x=2 and y=5,

then 8*2+5. Because the 2 is right next to the 8, it isn't '82', but '8*2'

According to  PEMDAS, multiplication is done first, so

8*2= 16,

16+5, which is 16+5= 21

Which expression is equivalent to 28/19/100
AleksAgata [21]
<span>The expression that is equivalent to that number is </span>20 + 8 + 0.1 + 0.09.

This is because the whole number 28 has a 2 in the tens place, meaning it has 2 tens, and 10x2=20. Same goes for the 8 in the ones place (8x1=8)
20+8=28. Then, 19/100 is equal to 0.19, which has a 1 in the tenths place and a 9 in the hundreths place put together to get 28.19

Which phone has a better price plan: IPhone 11 Pro or Samsung Galaxy S10? Why? What are the price plans? Brainliest for the best
jok3333 [9.3K]

Answer:

Samsung S10

Step-by-step explanation:

        Price Plans

iPhone 11 Pro: $41.67/mo.

Galaxy S10: $31.25/Mo

<u>_________________</u>

         Why?

<em>The Galaxy S10 has a 6.1-inch screen that's slightly larger than the iPhone 11 Pro's 5.8-inch display. It's also sharper than Apple's iPhone, or at least it should be on paper. ... But having a higher resolution doesn't always mean one screen is better than the other.</em>
