Answer:
she needs 25% more
Step-by-step explanation:
every two gifts is 25%. so 2,4,6 thats 75% so she needs 25% more to make 100%
It would be 4... You would take 28÷7
30(x - 10) = 120
Use distributive property to remove the parenthesis
30x - 30(10) = 120
30x - 300 = 120
move the constant to the right side
30x - 300 = 120
30x = 120 + 300
30x = 420
solve for x by moving 30 to the right side, multiplication will be division after moved to the right side
30x = 420
x = 420/30
x = 14
The value of x is 14
S4=935 found the infinite series
