The picture in the attached figure
let
AB=x
we know that
perimeter of the figure=10*x
perimeter=42.5 cm
so
42.5=10*x
x=42.5/10
x=4.25 cm
area of the figure=area of rectangle +area of square
area of rectangle=4.25*(4.25*3)----> 54.1875 cm²
area of square=4.25²----> 18.0625 cm²
area of the figure=54.1875+18.0625-----> 72.25 cm²
the answer is72.25 cm²
Answer:
I'm not going to give you an exact answer because there could be many different ones
Step-by-step explanation:
The equations can be rewritten as:
2x - 7 = 7y
-4x + 19 = 3y
then you just insert a value for x and get the answer.
Answer:
39.43 for each dog
Step-by-step explanation:
<u>d = 2c (given) </u>
164 c + 23 d = 4140 sub in the above equation for d
164 c + 23<u> (2c)</u> = 4140
210c = 4140
c =19.71
d = 2c = 39.43
The number is 142
you first make an equation ;
86+x=2x-56
Add 56 to both sides
142+x=2x
Subtract x from both sides
142=x
That is not correct, it depends on the numbers you are referring to. For instance, 75% of 100 is 75, but 50% of 1000 is 500, so in this case the 50% of a number is higher than 75% of another number. Although, is true that 75% is higher than 50% of the same number always.
