No, actually the method is not correct. Adiya needed to take x2 and subtract it from 20x. she would then get 6 = 18x. Have in mind also that she needed to divide 18. So 6 = 18x turns into 6=X. That is why is incorrect
..Answer:
Step-by-step explanation:
...
We know,
1 unit : 5 feet
so, 120 ft = (120 / 5) units
= 24 units
75 ft = (75 / 5) units
= 15 units
∴ Dimensions of scale drawing is 24 units by 15 units.
Answer: 60
Step-by-step explanation:
From the question, we are informed that 430 students were surveyed and 258 said that their favorite type of pet was a dog. The fraction/decimal of those that chose dog as their favorite pet will be:
= 258/430
= 3/5
= 0.6
Suppose that only 100 students were surveyed, the number of students that would say that a dog is their favorite types of pet will be:
= 0.6 × 100
= 60
D
the n th term (explicit ) formula for a geometric sequence is
= 
The given explicit formula therefore has
= 5 and r = - 
The recursive formula, allows us to find the next term in the sequence from the previous term
Here the next term in the sequence is obtained by multiplying the previous term by -
= 
(- ) with = 5
