Answer:
x=10
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
7x-3 + 12x-7 = 180
Combine like terms
19x-10 = 180
Add 10 to each side
19x-10+10 = 180+10
19x = 190
Divide by 19
19x/19 = 190/19
x= 10
Answer:
No the student is not correct because the answer is 0.4761. All the student did was wrong was the adding up the zeros.
Step-by-step explanation:
This is false. An arbitrary number is the same as a random number. It is any number that is not specified, not restricted and not consciously thought of. Simply put, an arbitrary number or a random number is any number that you can think of.
A boy stands 1 meter away from a lamppost. He is 1.8 meters tall and casts a shadow 2 meters long in the light from the lamp
The diagram is attached below using the given information
We have two similar triangle
Triangle ACD is similar to triangle ABE. So the sides are in proportional

AC = AB + BC = 3m

2x = 1.8 * 3 (cross multiply)
2x = 5.4
Divide by 2 on both sides
x = 2.7
Height of Lamppost is 2.7 meter
Answer:
2.72 inches
Step-by-step explanation:
1.4/1.12 = 1.25
3.4/1.25 = 2.72
