If the length of the sides of this triangle are in the extended ration: 3: 10:12; then we can express the length of its sides as: 3x ,10x and 12x.
The length of the longest side will be: 12x
Perimeter of a rectangle is the sum of all sides.
Therefore
We can suggest the following equation:
3x+10x+12x=400
25x=400
x=400/25
x=16
Therefore; the length of the sides would be:
3x=3(16)=48
10x=10(16)=160
12x=12(16)=192
Answer: the length of the longest side would be 192 cm.
Answer:
7(x+4)-6(x+3)=x+5
or , 7x + 28 - ( 6x + 18 ) = x + 5
or , 7x + 28 - 6x - 18 = x + 5
or , x + 10 = x + 5
The equation is incorrect !!
Use PEMDAS:
[(30+6) -3^2] / 9* 2
= (36 -9)/ 9* 2
= 27/9* 2
= 3*2
= 6
The final answer is 6~

Step-by-step explanation:
2+3.25=5.25 or 5 1/4 cups of flour total
Answer:

Step-by-step explanation:
So y=mx+b tells us the initial amount is b (also known as the y-intercept).
Anyways you have to pay a one time fee of 35 dollars and then it is 50 dollars per month.
Let x represent the number of months she goes to yoga.
If she goes 1 month it costs her 35+50.
If she goes 2 months it costs her 35+50+50 or just 35+50(2).
If she goes 3 months it costs her 35+50+50+50 or just 35+50(3).
If she goes x months it costs her 35+50x.
Now she only has 1325.
So we want the cost of her x months to be less than or equal to 1325 because she doesn't have more than that.
So we want
