So you have:
1) Start off by multiplying both sides by x to simplify the problem:
2) Now isolate the x by moving all terms with x onto one side and all other terms onto the other side:
3) Finally, divide by 3 on both sides to find the value of x:
------
Answer: x = 
Answer:
you put the variable first
Step-by-step explanation:
Jamie is correct. the reason is because when you put 7x you dont reverse it because we dont know what to multiply 7 by as when its 7x we know to multiply 7 by x
Step 1: Find the slope
Every 3 magnets that you buy, you need to pay 1 more dollar. Therefore, if you have 9 magnets, the cost will be 3 dollars. Also, if you have 6 magnets, the cost will be 2 dollars. Finally, if you have 3 magnets, the cost will be 1 dollar. So... the correct options are Options B, E, F
Answer options: B,E,F
Triangles IJK and LMN are similar. Then, the proportion between their similar sides must be equal. That is:
IJ/ML = JK/MN = IK/LN
where:
IJ = x
JK = 54
IK = y
MN = 42
ML = 28
NL = 35
In order to find the value of y, you consider the equation JK/MN = IK/LN, and solve for y, just as follow
JK/MN = IK/LN replace by the values
54/42 = y/35 multiply both sides by 35
(54/42)(35) = y
45 = y
Hence, y = 45
