Answer:
Mrs. Wong spend $545.76 on tiles.
Step-by-step explanation:
Mrs. Wong has 144 tiles that she is going to place on her square kitchen floor. If the tiles are $3.79 each, how much did Mrs. Wong spend on tile?
we are given
number of ties=144
cost of one tie=3.79 dollar
we have to find
total cost of 144 ties
for this we will multiply 144 by 3.79
multiplying 144 by 3.79 gives=144*3.79
it other words
one tile cost=$3.79
and for 144 ties cost
multiplying 144 on both sides
144 tiles cost=3.79*144=$545.76

By definition we have an integer number given by:
An integer is an element of the numeric set that contains the natural numbers {N} = {1,2,3,4, ...}, its opposite and zero.
On the number line we find the negative numbers to the left of the zero and to its right the positive numbers.
We have then, according to the definition, that the following are whole numbers:
-527, 1
Answer:
B = {x | x is an integer}
-527 ∈ B
1 ∈ B
option D
Answer: x = - 8
Step-by-step explanation:
= 8
cross multiplying , we have
8 ( 7 + x) = x
Expanding the Left Hand Side of the equation , we have :
56 + 8x = x collecting the like terms , we have
56 = x - 8x
56 = -7x
dividing through by - 7 we have :
- 8 = x
Therefore :
x = -8
