Answer:
A . The numbers are 6 and 7, with the smaller number as 6
B. The number is 135
Step-by-step explanation:
A. Let the numbers be a and b
adding both gives 13
a + b = 13 •••••(i)
difference between the two is 1
b - a = 1 ••••••(ii)
So we have two equations that we can solve simultaneously;
b = 1 + a; Substitute this into 1
a + 1 + a = 13
2a + 1 = 13
2a = 13-1
2a = 12
a = 12/2
a = 6
b = a + 1 = 6 + 1 = 7
The numbers are 6 and 7 while 6 is the smaller number
B.Let the number be x
Divide by 5; x/5, then subtract 2 , we get 25
x/5 - 2 = 25
x/5 = 25 + 2
x/5 = 27
x = 5 * 27
x = 135
Are you trying to subtract?
If so, the answer is -5,333.
Answer:
x = -17/26
Step-by-step explanation:
4(7x - 1) = 3(2x + 1) - 4(x + 6)
distribute 4 through the parentheses (do 3 and -4 as well)
28x-4=6x+3-4x-24
collect like terms
28x-4=2x+3-24 --> 28x-4=2x-21
move the variable
28x-2x-4=-21
collect like terms
26x=-21+4 --> 26x=-17
then divide
hope this helps and makes sense! :)
Answer:
consistent
Step-by-step explanation:
The solution to a system of equations is at the point of intersection of the 2 lines.
There is only one point of intersection, thus
The system has 1 solution and is consistent
Answer:
AC<AB+BC
If you were to flatten out the distance AB and BC, logically speaking, you'd get a larger distance than the distance AC.
