the length of the sides of a triangle are in the extended ration 3 : 10 : 12. the perimeter is 400 cm. what is the length of the
timofeeve [1]
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.

Solve each equation. 7(x+4)-6(x+3)=x+5
Gelneren [198K]

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 !!

Question 7!!!! 12 points
rosijanka [135]

Answer:

35+50x\le 1325

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 35+50x\le 1325
