2x - y = 5 also equals 4x - 2y = 10
4x-2y=10
+3x+2y=4
7x = 14
x = 2
2(2) - y = 5
-y = 1
y = -1
so, B. (2,-1)
The median is 50, answer B. It is the middle number of the data set so it is the median. If there are an even set of numbers, so obviously there will be two numbers in the middle, then you simply need to add them and divide by two. Hope this helps! :)
The common difference is B. 5 because the numbers are increasing by 5.
Answer:
(E) 27
Step-by-step explanation:
Let the 5 digit palindrome be PQRQP
Since each digit is chosen from 1,2,3 therefore
P can either be 1,2 or 3 which gives us 3 options.
Q can also either be 1,2 or 3 which gives us 3 options
R can either be 1,2 or 3 which also gives us 3 options
So we have 3^3 = 3*3*3
= 27
This means 27 palindromes are possible if they are formed using one or more of the digits, 1, 2, 3.
Answer:
Chloe received $11 as change if she gave the clerk $50
Step-by-step explanation:
We are given that Chloe purchased a sweater that cost $24, and a shirt that cost 5/8 times as much as the sweater.
Cost of sweater = $24
Cost of shirt =
So, Total cost of shirt and sweater = 24+15=39
Now She gave $50 to clerk
So, Change received by her = 50-39=11
So, Chloe received $11 as change if she gave the clerk $50
