Answer:
The product of the original numbers: xy
The product of the altered numbers (.75x)(.5y), or 0.375xy
The product has decreased by 1 - 0.375, or 0.625, or 62.5%
Answer:
x= -7/10 or x= -0.7 , y= 7
Step-by-step explanation:
Find the x-intercept: Find the y-intercept:
y= 5×2+10x-3 y= 5×2+10x-3
0=10+10x-3 y= 5×2+10×0-3
0=7+10x y= 7
-10x=7
x=-7/10
Remember that that the further the the left a digit is, the bigger the number, for example 0.8 is bigger than 0.08 which is in turn bigger than 0.008
Using this we can see that;
0.9, 0.71
Are the only two numbers bigger than 0.7
Answer:
15N + 21
Step-by-step explanation:
We are given that,
Amount of carpet bought by Peter = N meter²
The cost per meter square of the carpet = $15
So, the cost of 'N' meter square of carpet = 15N dollars.
Also, the delivery charge for the carpet = $21
Thus, the total cost of the carpet is given by,
Total cost = Cost per square meter + Delivery charge
i.e. Total cost = 15N + 21 (in dollars).
Hence, the expression representing the cost in dollars is '15N + 21'.
