B would be the correct answer. If you take 4:13 in order to form a ratio equal to that you have to multiply both sides of the ratio by the same number. 4*4=16 and 13*4=52
Answer:
Expose both of left side and right side.
For example: on the left side: 2(x+6) = 2x + 6.
Answer:
1.D
2.B
Step-by-step explanation:
For the first one divide see which one is less which is D
For the second one Ive always used the method kcf keep change flip so you keep
the change ÷ to multiplication so then flip
so the equation would be
x
so multiply the 15 by 9 then you get 135 then divide by 2 so thats your answer
Answer:
13.015625
Step-by-step explanation:
Answer:
The width is 7 meters and the length is 13 meters
Step-by-step explanation:
The perimeter of a rectangle sandpit is 40 meters.
Let the width be w units, then the length which is 1 meter less than twice it’s width becomes: 
The perimeter of a rectangle is given by:

We substitute P=40 and the length in term of w to get:

We simplify to get:

Divide through by 2 to get:
Hence
