Answer:

x+x=8

that's mean: 2.x/4 + 4.x/1 = 18/1

we find at least a common multiple of 4 and multiply the units by 4

2x + 16x = 72

18x = 72/:18

x = 4

Answer: 7

suppose: the smaller number is a

the larger number is b

because The sum of two numbers is 8 => a + b = 8 (1)

four times the smaller number is added to two times the larger number, the result is 18 => 4a + 2b = 18 (2)

(1)(2) => a + b = 8

4a + 2b = 18

<=> a = 1

b = 7

=> the larger number is 7

Are the triangles below similar? How do you know? Select one: a. yes, by AA~ b. yes, by SSS~ c. no d. yes, by SAS~ Have a good d

Gemiola [76]

Answer:

Yes, they are similar by SSS.

Step-by-step explanation:

You can see that the triangles have proportional sides. 12/8 = 1.5, 7.5/5 = 1.5. Since the sides have the same ratios, these triangles are similar!

calculate the total potential energy in kj of an object whose mass is 20 kg when it is located 20 m below a datum level in a loc

Airida [17]

Answer:

The energy in object is 3.8 Kilo Joules.

Step-by-step explanation:

We are given the following in the question:

Mass = 20 kg

Height,h = 20 m

g=9.5 m/s^2

Formula:

Potential energy =

$E = Mgh$

Putting value we get,

$E = 20(20)(9.5)\\E = 3800~J\\E = 3.8~KJ$

Thus, the energy in object is 3.8 Kilo Joules.
