Answer: 5x - 7 = 9
Explanation:
Let's think the unknown number as, "x"
Product means multiplication so 5 multiply the unknown number which is 5x. Seven less mean's to subtract so 5x - 7. And then the result is 9. So 5x - 7 is 9 or 5x - 7 = 9.
Sorry for not providing enough explanation last time. But I hope this is enough-
Answer:
DC=30
CM=15
Step-by-step explanation:
Given
Triangle DEF with C centroid
DM=45 (length of median)
centroid divides median in the ratio 2:1(larger side at vertex)
⇒
DC
⇒DC=30
DC+ CM=DM
30+CM=45
⇒CM=15
Answer: 6.25 IF my assumption is correct about the missing x!
The Other way around: 4.5 with 2x² + y² / 3
Step-by-step explanation: 2y² + y² / 3 assuming the 2nd y should have been x, 1st y is y, and all divided by 3
2(3)² + (1.5)² / 3
2(9) + 2.25 /3
18 + 2.25 /3
20.25/3
6.25
Edited to correct!________ OR 2y² + y² / 3 assuming the 1st y should have been x, 2nd y is y, and all divided by 3
2(1.5)² + (3)² / 3
2(2.25) + 9 / 3
4.5 + 9 /3
13.5 /3
4.5
Answer:
C
Step-by-step explanation:
The expression at the top is equal to 12/10 or 6/5
Option C, or 4/5 x 3/2, is also equal to 12/10
Answer:
Elimination
Step-by-step explanation:
Graphing takes too long, substitution can sometimes complicate things quickly, therefore I would use elimination as my prime method of solving systems of equations.
