Please help!!!!!!! im so confused lol
pav-90 [236]

Answer:

a : c = 7 : 10

Step-by-step explanation:

The two ratios (a : b and b : c) both have b in common, so to work out what a : c is, we can use b to 'bridge' the two ratios together.

However, in a : b, b is 4. But in b : c, b is 2. We need to make sure b is the same in both ratios before we can combine the ratios together. The easiest way to do this is to multiply b : c by 2 to get b : c = 4 : 10. Now b is 4 in both ratios.

So now, we can combine the two ratios together to get a : b : c = 7 : 4 : 10. Since we only want a : c though, we can just drop the b and get a : c = 7 : 10. No simplifying is necessary since the ratio is already in its simplest form.

Hope that helps! :)

2 less than four times a number is equal to twice a number increase by 8 write an equation and solve to find the value of x
Tom [10]
4x - 2 = 2x + 8
2x -2 = 8
2x = 10
x = 5

4(5)-2 = 2(5)+8
20-2 = 10+8
18 = 18

A square has a side that is (x-3) units long. If the area of the square is 126.5625 sq units, what is the value of x?
Kitty [74]

Answer:

14.25 units

Step-by-step explanation:

Area of a square= l*b= (x-3)(x-3)=x^{2}-3x-3x+9=x^{2}-6x+9

x^{2}-6x+9=126.5625

x^{2}-6x-117.5625

Solving the equation using quadratic equation then as attached

x=14.25 units

To prove

x-3=14.25-3= 11.25 units

area=11.25*11.25=126.5625 sq units
