Answer:
Length = 13 cm
Width = 10 cm
Step-by-step explanation:
We are told that;
- The length of the rectangle is 3 cm more than the width
- Thus taking, the width as x cm
- Then, the length will be (x+3) cm
- The perimeter of the rectangle is 46 cm
We are required to determine the dimensions of the rectangle;
We know that the perimeter of a rectangle is given by the formula;
P = 2(l+w)
In this case;
46 = 2 ( x + x + 3)
Thus;
4x + 6 = 46
Solving for x,
4x = 40
x = 10
This means, the width is 10 cm, while the length is 13 cm
Therefore, the dimensions of the rectangle is length 13 cm and width 10 cm
Answer:
-3,0.5
Step-by-step explanation:
The x coord is -3 so its either a or d. The second line says that x(-3) has to =-4 after subtracting 2y so 2y=-1 and y=0.5. So the x is -3 and the y is 0.5
Answer:
4/21 tablespoons of vanilla
Step-by-step explanation:
<u>Let's have the ratios:</u>
- 2/3 tablespoons of vanilla per 3 1/2 dozen cookies
- x tablespoons of vanilla per 1 dozen of cookies
<u>It is solved by cross multiplication as:</u>
- 2/3 × 1 = 3 1/2 × x
- 2/3 = 7/2x
- x = 2/3 ÷ 7/2
- x = 2/3 × 2/7
- x = 4/21
4/21 tablespoons of vanilla needed for 1 dozen of cookies
