Answer:
The dimensions of the rectangle are length = 7cm and width = 6cm.
Step-by-step explanation:
In order to solve for the dimensions, you will need to set up two equations in order to solve for the missing variable. Given the information that the length is 5 cm less then twice it's width, using 'L' for length and 'w' for width we get the following equation: L = 2w - 5. Perimeter is the sum of all the sides, or in the case of a rectangle P = 2w + 2L. We can then use our expression for 'L' in our perimeter formula: 26 = 2w + 2(2w - 5). First, using the distributive property we get: 26 = 2w + 4w - 10. Next, we combine like terms: 26 = 6w - 10. Then, we use inverse operations to isolate the variable: 26 + 10 = 6w - 10 + 10 to get 36 = 6w, divide both sides by 6 to get w = 6. Lastly, plug in the value of 'w' to 'L': L = 2(6) - 5 or L = 7.
The partial variation is A
Answer:
55,000
Step-by-step explanation:
I already explained it on another problem but I'll show the equation again.
0.74x = 40,700
x = 55,000
Answer:
18.18 /// 17.9982
Step-by-step explanation:
Multiplying by 100 means moving up the other number by two digits,
soo 100x (or 100(0.1818) is now 18.18
For the next one:
0. 1818
x 99
---------------
1.6362
16.3620
-------------
17.9982
I have no idea about that fraction part
Answer:
the answer would be C because you would do 60 x 25 which would give you 1,500
