In order to solve this let us for at assume that the value of the width is X. Therefore the length will be x+5.
We can now write an equation:
(X+5) + (X+5) + X + X = 58
Combining like terms we should get
4X + 10 = 58
Now subtract 10 from both sides to get
4x = 48
Divide by 4 now and you should get
X = 12
Now we know the value of X and therefore the width.
Answer:
C. 42.
Step-by-step explanation:
This is an arithmetic sequence with common difference d = 4 and first term a = -3.
Sum of n terms = (n/2)[2a + (n - 1)d]
Sum of six terms = (6/2)[2(-3) + (6 - 1)4]
= 3 * (-6 + 20)
= 42.
Answer:
m = 8
Step-by-step explanation:
-3m - 4 = -28
+4 +4
-3m = -24
÷-3 ÷-3
m = 8
A = Sock's weight
b = Princess' weight
c = Luna's weight
a : b = 4 : 5
b : c = 6 : 7
at this point, we have to change the 2 ratios (a : b and b : c) into one ratio (a : b : c)
to do that, we have to change the ratio number so the number b in both ratio is the same
a : b = 4 : 5 = 24 : 30
b : c = 6 : 7 = 30 : 35
From that we can conclude that
a : b : c = 24 : 30 : 35
Since we're looking for the ratio of Sock's weight to Luna's weight, it will be
a : c = 24 : 35
