Answer:
eight more than a fifth of a number
Step-by-step explanation:
k/5 is one-fifth of a number. When 8 is added to it, the result is ...
eight more than a fifth of a number
_____
There is no multiplication by 5, so any phrasing with "five times" is incorrect.
The one-fifth multiplier is applied only to k, not to any sum.
Each gray square: 2x2=4 tiles. 6 gray squares: 6x4=24 tiles.
Total number of tiles: 12x10 = 120, 24 of those are gray.
So 120-24 = 96 are white.
96-24 = 72 more white than gray
Answer:
31, 114 and 35
Step-by-step explanation:
I set up the equation as such:
(3x + 21) + (x + 4) + x = 180
then I combined like terms:
5x + 25 = 180
And then solving for x I get:
5x = 155
x = 31
And then plugged the solved x value into the terms to give:
(3(31) + 21) = 114
(31 + 4) = 35
alongside the found angle of 31.
Answer:
The larger number is 12 and the smaller number is 9
Step-by-step explanation:
Let us first deal with the first sentence of this word problem.
Let's call the larger number L
and the smaller number S
.
We know from the first sentence:
3
L =
4
S
We know from the second sentence:
L+S =
21
Let's solve this second equation for
L-
L+S =
21
-
L
S =
21
-
L
Now we can substitute 21
-
L for S in the first equation and solve for L :
3L = 4 (21
-
L)
3L + 4L = 84 - 4L + 4L
7L = 84
7L/7 = 84/7
L = 12
Next we can substitute 12 for L in the solution to the second equation:
s = 21 - 12
s = 9
