Answer:
21
Step-by-step explanation:
12/4.+18
The lcm is 4.
12+4(18) all divided by 4
12+72=84
84/4=21
Answer:

Step-by-step explanation:
two plus two equals four
Perimeter= 53+54+97= 204 yds
Area= 50x53x.5= 1325sq yds
Answer:
x = -2, y = 2
Step-by-step explanation:
-7x + 7y = 28
7y = 28 + 7x
y = 4 + x ----(1)
-8x+4y=24 -----(2)
sub (1) into (2)
-8x+4(4+x)=24
-8x+16+4x = 24
-8x+4x = 24-16
-4x = 8
x = -2
sub x = -2 into (1)
y=4+(-2) = 2
Answer:
Step-by-step explanation:
Let n represent the number
Twice the number =2n
4 times the number = 4n
Given that twice the number is atleast 3 less than four times the number
Algebraically this can be written as
2n≤4n-3
We can add 3 to both sides
So n should be atleast 1.5
If n is natural number or integer then least value of n is 2.
