Elliot collects miniature toy cars. He wants to fill 4 display cases.each display case holds 15 cars. He has 28 cars now, and he is able to buy 3 more every month with the money he saves from his allowance. How many more months will it be until elliot has enough cars to fill all 4 display cases?
Answer:
Elliot has to wait 11 months before he has enough cars
Step-by-step explanation:
Elliot has 4 display cases with each case being able to hold 15 cars. Thus we know
total # of cars Elliot can place in his display case = 4 * 15 = 60 cars
From this, we can figure out how many more cars Elliot needs by subtracting the amount of cars he already has
# of cars Elliot needs = 60 - 28 = 32 cars
Now to find the number of months Elliot needs, we divide by how many he can buy each month
# of months Elliot needs to save up for = 32 / 3 = 10 2/3
Assuming Elliot does not get his allowance until the end of the month, we will have to round the number of months up to the nearest integer, 11

Somsome pls help , step by step
Answer:
m= 3.5
Step-by-step explanation:
-2m- 6=-6+ 8m - Starting on the left side, Add 6 to both sides, to get a new equation of;
-2m = -6m +14 - Then, starting on the right now, add 6m to both sides, to get a new equation of;
4m = 14 - Then divide both sides by 4, to get your final answer of;
m = 3.5
68 lb 13oz - 30 lb 15 oz=
Answer:
37.875 lb (37 lb 14 oz)
Step-by-step explanation:
(There are 16 oz in 1 lb)
68 lb = (68 x 16 =) 1,088 oz
1,088 oz + 13 oz = 1,101 oz
30 lb = (30 x 16 =) 480 oz
480 oz + 15 oz = 495 oz
1,101 oz - 495 oz = 606 oz = (606 oz ÷ 16 =) 37.875 lb
Final answer:
37.875 lb (37 lb 14 oz)

someone pls help me and solve the problem showing there work!
Answer:
Hope this helps you understand
Step-by-step explanation:
-2m-6=-6m+8
Add 6 on both sides
-2m=-6m+14
subtract 14 from both sides.
-2m -14=-6m
Add 2m on both sides
-14=-6m

How to tell if your table is linear or exponential?
Answer: If the first difference is the same value, the model will be linear. If the second difference is the same value, the model will be quadratic. If the number of times the difference has been taken before finding repeated values exceeds five, the model may be exponential or some other special equation.
Step-by-step explanation: You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference. This table is linear.

An Eastbound train (E) traveling 95 mph and a Westbound train (W) traveling 110 mph leave the same train station at different times. After 4 hours, they are 4 00 miles apart. Which system of linear equations can be used to determine the time that each of the trains has been traveling?
Answer:
The system of linear equations that can be used to determine the time that each of the trains has been traveling is:
E + W = 4 ....... Equation 1
95 E + 110W = 400 ......Equation 2
Hence,
An Eastbound train has been travelling for = (E) = 2.67 hours
A Westbound train has been travelling for = (W) = 1.33 hours
Step-by-step explanation:
An Eastbound train (E) traveling 95 mph and a Westbound train (W) traveling 110 mph leave the same train station at different times. After 4 hours, they are 4 00 miles apart. Which system of linear equations can be used to determine the time that each of the trains has been traveling?
Speed = Distance/Time
Distance = Speed × Time
Let the time
An Eastbound train = (E)
A Westbound train = (W)
E + W = 4 hours ....... Equation 1
95mph × E + 110mph × W = 400 miles
95 E + 110W = 400 miles ......Equation 2
The system of linear equations that can be used to determine the time that each of the trains has been traveling is:
E + W = 4 ....... Equation 1
95 E + 110W = 400 ......Equation 2
E = 4 - W
We substitute 4 - W for E in Equation 2
95 (4 - W) + 110W = 400
380 - 95W + 110W = 400
Collect like terms
95W - 110W = 400 - 380
15W = 20
W = 20/15
W = 1.3333333333 hours
≈ 1.33 hours
E = 4 - W
E = 4 - 1.33 hours
E = 2.67 hours
Therefore,
An Eastbound train has been travelling for = (E) = 2.67 hours
A Westbound train has been travelling for = (W) = 1.33 hours

Which of the following represents the symmetric property of equality?
Question 5 options:
A)
If a = b and b = c, then a = c
B)
If a = b, then ac = bc
C)
a(b + c) = ab + ac
D)
If a = b, then b = a
Answer:
D. if a=b, then b = a
The symmetric property of equality is If a = b, then b = a. The correct answer is D.
What is symmetric property?According to the symmetric property, if x=y, then y=x is true for all real numbers x and y.
Given the relation of "equality" (=),
and a = b;
if b = a is true for all a and b, then equality is said to be symmetric.
The claim applies to all of a and b. (no counterexample can be found). The symmetric property of equality refers to this.
Example - If x + y = 3, then 3 = x + y.
Therefore, If a = b, then b = a is the correct answer.

How far will 25 N of force stretch a spring with a spring with a spring constant of 125 N/m?
Answer:
-0.656168ft
Step-by-step explanation:
If Spring force constant (k) is 125 N/m
And the force is (F) 25 N ,
then the spring displacement (Δx) -0.656168
Equation used:
Knowing Hooke's law, we can write it down it the form of a formula:
F = -kΔx
F is the spring force (in N);
k is the spring constant (in N/m); and
Δx is the displacement (positive for elongation and negative for compression, in m).
