Answer: x = 3
Step-by-step explanation: First subtract 2x from both sides to get:
3x + 6 = 15
Then subtract 6 on both sides
3x = 9
Now divide by 3 to isolate x to get...
x = 3
Answer:
okay
Step-by-step explanation:
Answer:52
Step-by-step explanation:
Given
one-fifth of the plants in a garden are grape tomato plant
two-ninth of the plants in the garden are cherry tomato plants
Also there are 18 grape tomato and 20 cherry tomato plants.
Let Total plants be x
Then Grape tomato plants 
x=90
thus there are total of 90 plants
also grape tomato+cherry tomato=18+20=38
Thus there are 90-38=52 remaining plants.
Since you know x is between 4 and 5, lets start in the middle using 4.5 for x
4.5^3 - 5(4.5) = 68.625 ( this is larger than 59, so we know the number is less than 4.5)
lets try 4.2: 4.2^3 -5(4.2) = 53.088 ( this is smaller than 59, so we know the number is larger than 4.2)
4.3: 4.3^3 -5(4.3) = 58.007
4.4: 4.4^4 -5(4.4) = 63.184
so we know the answer is between 4.3 and 4.4
4.32: 4.32^3 - 5(4.32) = 59.02 round to 59.0 ( to 1 decimal place)
I think this is what the teacher wants for an answer.
