Answer:
Divide 223 by 2: 223/2 = 111.5
Then fix one number to 111.5 - 0.5 ann the other to 111.5 + 0.5
The two numbers are 111 and 112.
Then the answer is 112.

A car initially moving at 4 m/s accelerates to a new velocity of 10 m/s in a time of 3
seconds. What was the acceleration of the car?
Step-by-step explanation:
Hey there!
Given;
Initial velocity (u) = 4m/s
Final velocity (v) = 10m/s.
Time(t) = 3s
Acceleration (a) = ?
We know;
[tex]a = \frac{v - u}{t} [/tex]
Keep all values.
[tex]a = \frac{10 - 4}{3} [/tex]
Simplify it.
[tex]a = \frac{6}{3} [/tex]
Therefore, acceleration is 2m/s^2.

Alex is putting trim around the window below. 8 ft 6 ft If the trim costs $2.95 per foot, approximately how much did Alex spend on window trim? 0 A. $83 O B. $93 O C. $121 D. $142
Answer:
Step-by-step explanation:
Given: He needs 8ft and 6 ft
The trim costs 2.95 per foot
so if we do 8 times 2.95 we get 23.60
Next we do the same with 6 and we get 17.7
Add then together and we get $41.30

Denver is planting strawberry seedlings in a new garden. He can plant 3 rows of a certain length with 2 seedlings left over or 4 rows of the same length with 3 seedling spots left empty. What is the length, x, of each row in meters?
Answer:
The length of each row is 5 m.
Step-by-step explanation:
It is given that,
Denver can plant 3 rows of a certain length with 2 seedlings left over and 4 rows of the same length with 3 seedling spots left empty.
Let the length of each row is x.
Case 1,
Total number of seeds = 3x+2
Case 2,
Total number of seeds = 4x-3
From both of the cases,
3x+2 = 4x-3
Taking like terms together,
3x-4x=-3-2
-x=-5
x=5
So, the length of each row is 5 m.
If you are trying to decide whether a system of equations has a solution, would you rather have the equations or the graphs? Why?
When determining if the set of equations has a solution, this is when graphing is the best method to be used.
What are linear equations in two variables?If an equation is written in the form axe + by + c=0, where a, b, and c are real integers and the coefficients of x and y, i.e., a and b, respectively, are not equal to zero, then it is said to be a linear equation in two variables.
When there is a system of equations, there are mainly three solutions for equations that are,
no solution, unique solution, and infinitely many solutions,
these solutions can be found by solving the equations or comparing their variables, hence the process takes more time,
but the same process for finding the solutions can be done by graphing method and it is easy as compared to the above method because,
As it offers the visual to record what they have actually looked for, it was seen to be the greatest way at the time it was taught to new students for solving the system of two equations in two variables.
Hence graph method is best to find the solution to equations.

Two trains leave stations 204 miles apart at the same time and travel toward each other. One train travels at 90 miles per hour while the other travels at miles per hour. How long will it take for the two trains to meet?
Answer:
t = 1.23 hours
Step-by-step explanation:
Given that,
Distance between two stations is 204 miles
One train travels at 90 miles per hour while the other travels at 75 (let) miles per hour.
We need to find how long will it take for the two trains to meet.
As both cars travel toward each other, it means they approach with a speed of 90 mph + 75 mph = 165 mph.
Let t is the time when they meet. So,
[tex]t=\dfrac{d}{v}\\\\t=\dfrac{204}{165}\\\\t=1.23\ h[/tex]
It will take 1 hour 23 minutes for the trains to meet.

i need help with multiplying decimals i ust dont get it i also need help with dividing decimals
Answer:
To multiply decimals, first multiply as if there is no decimal. Next, count the number of digits after the decimal in each factor. Finally, put the same number of digits behind the decimal in the product.
To divide a decimal by another decimal: Move the decimal point in the divisor to the right until it is a whole number. Move the decimal point in the dividend to the right by the same number of places as the decimal point was moved to make the divisor a whole number. Then divide the new dividend by the new divisor.
Answer:
Step-by-step explanation:
Okay, first multiplying decimals:
If you want to multiply decimals first you have to put the 2 decimals one on top of each other
for example:
2.27
x 4.89
Then multiply it just like if you were multiplying a regular number without the decimals
227
x 489
This equals 111,003 now to figure out the answer we can count that there are 4 numbers after the decimal point so you move the decimal point 4 to the left so the answer would be 11.1003

Answer:
13. x = 21; y = 15
14. x = 8; y = 11
15. x = 16; y = 23
Step-by-step explanation:
13. (3x - 16)° + (6x + 7)° = 180° (same side interior angles are supplementary)
Solve for x
3x - 16 + 6x + 7 = 180
Collect like terms
9x - 9 = 180
Add 9 to both sides
9x = 180 + 9
9x = 189
Divide both sides by 9
x = 189/9
x = 21
(6x + 7)° = (11y - 32)° (vertical angles are congruent)
Solve for y by substituting x = 21 into the equation
6(21) + 7 = 11y - 32.
126 + 7 = 11y - 32
133 = 11y - 32
Add 32 to both sides
133 + 32 = 11y
165 = 11y
Divide both sides by 11
165/11 = y
15 = y
y = 15
14. (11x - 25)° = (8x - 1)° (alternate exterior angles theorem and corresponding angles theorem)
Solve for x
11x - 25 = 8x - 1
Collect like terms
11x - 8x = 25 - 1
3x = 24
Divide both sides by 3
x = 24/3
x = 8
(8x - 1)° + (15y - 48)° = 180° (linear pair theorem)
Substitute x = 8 into the equation and solve for y
8(8) - 1 + 15y - 48 = 180
64 - 1 + 15y - 48 = 180
15 + 15y = 180
Subtract 15 from both sides
15y = 180 - 15
15y = 165
Divide both sides by 15
y = 165/15
y = 11
15. (7x - 44)° = (4x + 4)° (alternate exterior angles theorem)
Solve for x
7x - 44 = 4x + 4
Collect like terms
7x - 4x = 44 + 4
3x = 48
Divide both sides by 3
x = 48/3
x = 16
39° + (8y - 43)° = 180° (corresponding angles theorem and linear pair theorem)
Solve for y
39 + 8y - 43 = 180
Collect like terms
-4 + 8y = 180
Add 4 to both sides
8y = 180 + 4
8y = 184
Divide both sides by 8
y = 184/8
y = 23
