Answer:
6/35
Step-by-step explanation:
of means multiply, so just do 2/7 times 3/5
A) x = 0.296
B) x= 15
Step-by-step explanation:
Step 1:
(2/3) : x :: 4.5 :2
By using expansion method,
(2/3) × 2 = 4.5 x
x= (2/3) × 2 / 4.5
x = 0.296
Step 2:
(2/3) : (1/5) :: 50 :x
By using expansion method,
(2/3) x = (1/5) × 50
x= (1/5) × 50 / (2/3)
x = 15
Answer:
30 square feet
Step-by-step explanation:
Number of tiles used for covering the kitchen floor = 10
Area covered by the floor = 6 * 5 feet^2
= 30 square feet
Length of each tiles = 3 feet
Width of each tiles = w feet
Area covered by each tiles = 3w square feet
Then the equation can be written as
3w * 10 = 30
30w = 30
w= 30/30
= 1 feet
10 *3w = 30
Remove the brackets
6 - t + 7 - t - 4 + t = 0
Eliminate the two opposite t because they cancel out to each other
6 + 7 - t - 4 = 0
Add and subtract
6 + 7 - 4 = 9
Thus:
9 - t = 0
Bring the 9 over to the 0 to isolate the -t
-t = 0 - 9
Calculate:
-t = -9
To get rid of the negative on the variable we have to divide it by -1 to make it positive bc negative divided by negative equals positive. Since we are dividing -1 to the -t we also have to divide -9 by -1.
t = 9
