J Multiply the first equation by 3
F Add the two equations and solve for x
G x = -3
B Substitute the value of x in the first equation, y = 1
C the solution is (-3, 1)
Equivilent means equals to
0.25 means 25 hundreths
hundreths is 1/100
25 hundreths=25/100=5/20=1/4
so it could be
0.25 kg=1/4kg
Answer:
682/15
Step-by-step explanation:
When working with very large or very small numbers, scientists, mathematicians, and engineers often use scientific notation to express those quantities. Scientific notation uses exponential notation. When a number is written in scientific notation, the exponent tells you if the term is a large or a small number. A positive exponent indicates a large number and a negative exponent indicates a small number that is between 0 and 1.

Answer:
? = 49
Step-by-step explanation:
To solve this we just need to understand that when A=1, B=7. So when the side for a is 7 that is basically multiplying A by 7 so we have to do the same to the B side. So when the B side is multiplied by 7 it would be 7*7 =49 so the ? is equal to 49 when that similar side is equal to 7.
This is all based on the fact that the two triangles must be similar triangles.
