Answer:
86 is a term in the sequence
Step-by-step explanation:
2; 6; 10; 14; 18;.....
T1=1*4-2=2
T2=2*4-2=6
T3=3*4-2=10
T4=4*4-2=14
T5=5*4-2=18
......................
Tn=n*4-2
n*4-2=86
n*4=88
n=88/4
n=22
86 is T22 in the sequence.
Answer:
75
Step-by-step explanation: 2 times 30 is 60 30 divide by .5 is eqaul to 15 becasue it is half
and 60+15=75
The first step to solving a story problem is identifying variables. For this problem, I will identify the variables as:
D = Drew's age
J = Jimmy's age
Once the variables are identified, we need to find as many equations as we have variables. Since we have two variables, we will have to write two equations.
Since Drew is 3 years younger than Jimmy: D + 3 = J
Since the sum of the brothers' ages is 21: D + J = 21
Once I have two equations is two variables, I can solve the system using either substitution method or elimination method. For this problem, I will use substitution method.
D + J = 21 Equation 2
D + (D + 3) = 21 Substitution of value of J from equation 1 into equation 2
D + D + 3 = 21 Associative property of addition
2D + 3 = 21 Simplify
2D + 3 - 3 = 21 - 3 Subtract 3 from each side
2D = 18 Simplify each side
2D/2 = 18/2 Divide each side by 2
D = 9 Simplify each side
Now that we have D, we can substitute it into equation 1 to get the value of J
D + 3 = J Equation 1
9 + 3 = J Substitution
12 = J Simplify
I would say D. point G would be the correct answer
Answer:
75
Step-by-step explanation:
$12 is 3 times $4, so we can expect to buy 3 times 25 cartons.
You can buy 75 cartons of mostly-melted ice cream for $12.
