Answer:
The best correct option is C
x = 1.79 to x = 3
Step-by-step explanation:
Making the sport off all little thing that crowed. They are still grouped into 7. Option C is theost appropriate.
The two expressions that would have the same product as 3.5 x 5.12 are:
184.32 x 1/12
76.8 x 3/12
<h3>What is the product of the a number?</h3>
The product of a number is the value that is derived when two or more numbers are multiplied by each other.
Product of 3 and 5.12 is 15.36.
In order to determine what number should be multipled by 1/12 to yield 15.36, multiply 15.36 by 12: 15.36 x 12 = 184.32
In order to determine what number should be multipled by 3/12 to yield 15.36, multiply 15.36 by 4: 15.36 x 4 = 76.8

Answer:
X=60°
Y=50°
Step-by-step explanation:
Triangles must equal 180° when you add all angles together.
<u>Triangle</u><u> </u><u>with</u><u> </u><u>angle</u><u> </u><u>X</u>
To find the value of Y takes a few more steps, but it isn't hard!
Angle Y is on a line, which equals 180° just like a triangle.
We know X=60°, but we don't know what the blank angle equals.
We use the same steps as we did when finding X
- 60+50=110
- 180-110=70
- Blank angle=70°
We know that the blank angle=70° and that X=60°
Since the line equals 180, we add the two angles and then subtract from 180, just like before!
- 70+60=130
- 180-130=50
- Y=50°
