Answer:
3x - 48y + 5z = 0
Step-by-step explanation:
First simplify the sides.
7x + 7y + 5z = 4x + 55y
Subtract the like terms:
3x - 48y + 5z = 0

Some key concepts to remember:
- One -to -one means each element has an element only it matches to. This is only possible when sets have the same number of elements. #1 doesn't but #2 does.
- To determine the number of one-to-one correspondence, use a factorial with the number of elements. 4 is the number and the factorial is 4! = 4*3*2*1 = 24.
- n(A) means the cardinal number of the set or the number of unique elements. Elements count only once even if they repeat. There are 5 in #4 and 12 in #5.
Answer:
$210
Step-by-step explanation:
Given data
time = 6 weeks
initial amount= $90
saving per week = $25
Hence the expression for the total savings after the 6 weeks is given as
y= mx+c
where
m= $25
x= 6 weeks
c= $90
substitute
y=25*6+90
y= 150+60
y= $210
Hence the total amount after 6 weeks is $210
Answer:
Since 100<105<121, 10<square root of 105<11. So the square root of 105 is between 10 and 11.
