Answer:
Option A, B, and D are true.
Explanation:
A coefficient is the number that is being multiplied by a variable. For example, in 7b, 7 would be the coefficient.
Terms are the numbers used in the equation. For example, in 3 + 2, 3 and 2 would be the terms.
3n and 5m are not coefficients as there are variables included. 3n and 5m are examples of a variable.
A constant is a number that is not multiplied by a variable. For example, in 8x + 3 + 2b, 3 would be the constant.
Hope this helped :)
Step-by-step explanation:
to know whether it is geometric progression or not, you need to find the common ratio. to find the ratio divide the (n+1)th term by n th term
so, 12/-4 = -3
also, -36/12 = -3
here u see the ratio is always same, i.e., common ratio.
thus u can say it is a geometric series with common ratio -3
Answer:
6 hours
Step-by-step explanation:
The equation for this would be
c=3h+12
It costs $3 per hour, and there is a $12 cost no matter how many hours the bike is rented for
We know,c, or the cost is $30, so we can substitute that in
30=3h+12
Solve, by isolating the variable,h
First, subtract 12 on both sides
30=3h+12
18=3h
Divide by 3 on both sides
h=6
So, she rented the bike for 6 hours
Answer:
x<1
Step-by-step explanation:
10x + 80 < 90
10x < 90 - 80
10x < 10
x < 1
