Answer:
3
Step-by-step explanation:
Find the number in the whole number place 3 and look one place to the right for the rounding digit on the right side of the decimal point 4. Round up if this number is greater than or equal to 5 and round down if it is less than 5.
Answer: 3.5 integers can be in decimals too. and any number counts as an integer except for 0
no solution because the square root of a negative number is not a real number d=-100
1. -19x
3. 23 - 8x
5. -18x + 2y
first: 3x - x = 2x
2x - 22x = -20x
-20x + x = -19x
second one:
8 - (-15) = 23
12x - 20x = -8 x
23 - 8x
third:
-10x - 8x = -18x
3y - y = 2y
-18x + 2y
let the number be y
4(y-7)=48
y-7=48/4
y-7=12
y=12+7=19
