Jane builds toy trains that have 5 train
cars each. She uses 20 train cars in all.
How many toy trains does Jane make?
toy trains
Answer:
Here's how to solve it.
Step-by-step explanation:
Okay,
from what I understand she has 20 train cars total.
She uses 5 for each train.
So to solve you use simple division.
20 / 5 = 4
To check your answer substitute 4 in the equation so 4 × 5 does equal 20.
So it would be 4.

aluminum, inc. produces cams at a rate of 0.04 per hundredth of a second. how many cans can be produced in a 7-hour day?
Answer:
Step-by-step explanation:
100800
1008 can s can be produced in a 7 hour day.
What is per thousands of a second ?Just divide 1 second by 1000 which is 0.001 secs.It can also be called as 1 millisecond.
According to the given question aluminium, inc. produces cams at a rate of 0.04 per hundredth of a second. this can be numerically expressed as
0.04 cans produced in 0.01 seconds.
We know 7 hour is = (7×3600) seconds which is = 25200 seconds.
∴ In 7 hours aluminum, inc. can produce (25200 × 0.04) which is
= 1008 cans.

What property justifies step 4?
a. Commutative Property of Addition
c. Multiplication Property of Equality
b. Addition Property of Equality
d. Substitution
Answer:
Step-by-step explanation:
A.
Option A is correct. The property that justifies step 4 based on the calculation is the Commutative property of addition.
Equations are expressions separated by an equal sign.
Given the equation:
2(x-3) + 3x = 19
Expand the parenthesis using the distributive law
2x - 2(3) + 3x = 19
2x - 6 + 3x = 19
Collect the like terms
2x + 3x -6 = 19
Step 4
Since 2x+3x = 3x+2x = 5x (according to the commutative law), the expression becomes:
5x-6 = 19
Step 5
Add 6 to both sides
5x-6+6 = 19+6
5x = 25
x = 25/5
x = 5
Hence the property that justifies step 4 based on the calculation is the Commutative property of addition.

22 - 27 + 10 = 5Option B)Answer:
1.) C
2.) C
3.) A
5.) B
Step by-step explanation:
1.) because 14 is positive and the opposite of 12 is -12. So 14+-12=2!
2.) to get to 7 from -7 you would have to take 7 units to get there.
3.)Given that a football player caught the ball and made a gain of 8 yards on the first play. On the next play the team lost 12 yards.we are to find the number of yards needed to gain on the next play to get back to their original position.Let, x be the number of yards that the team had originally.On the next play, the team lost 12 yards, let 'k' be the number of yards needed to gain on the next play to get back to their original position.Thus, the number of yards needed to gain on the next play to get back to their original position is 4.
5.) We have been given that on Monday morning the temperature was 38°F, but by the afternoon the temperature had risen 22°F. We are also told that on Tuesday morning the temperature had dropped 27°F since Monday afternoon.Since the temperature rose by the Tuesday noon, so temperature by Tuesday noon will be 10 degrees greater than temperature by Tuesday morning.To find the number of degrees temperature is above or below 38°F on Tuesday at noon we will subtract 38°F from the temperature on Tuesday at noon. Since the difference between temperature is positive, therefore, the temperature on Tuesday at noon was 5 above .

Line A has a slope of −3 . Line B has a slope of 4. Line C has a slope of 2
Which Line Is The Closest To Being Horizontal?
- Line A
- Line B
- Line C
- I dont Know
The line whose absolute value of the slope is least will be the slope which is close to being horizontal. Hence, line C is the answer.
An horizontal line has will have a slope value of 0. Hence, the steeper the slope, the greater the absolute value of the slope obtained. This means that a line deviates more from being horizontal as the absolute value of the slope increases.Therefore, the line with least absolute value would be the closest to being horizontal, hence, line C with an absolute value of 2.

Sandy purchased a dining room set for $1,140 using a 12-month deferred payment plan with an interest rate of 26.78%. She did not make any payments during the deferment period. What will the total cost of the dining room set be if she must pay off the dining room set within two years after the deferment period? (2 points) a $1,140.00 b $1,485.70 c $1,935.12 d $2,902.68
Answer: C.) $1,935.12
Step-by-step explanation:
Using the deferred annuity calculator :
Principal amount = 1140
Interest (r) = 26.78% = 0.2678
Period of payment = 2 years, compounded monthly, n = 24
Using the deferred annuity calculator ; Total balance = $1936.24
Hence, the closest cost in the option is $1,935.12
The following are rules for repeating patterns. For which rule will the 12th shape be a circle?
A. Triangle, Circle,Square
B. Circle, Square
C. Rectangle,Circle
Circle, Circle, Triangle
The third pattern because you can divide 12 by the number of shapes in the sequence and start counting from the remainder.
In this case choice C has 5 shapes. 12/5 is 2, with a remainder of 2.
The second term in choice C is Circle, so choice C is the answer.
Of course, you can also list them all out.
If there is no remainder when you divide then the 12th term is the last term in the sequence.
