six less than twice a number x is 38 whats the value ofx
Answer:
x=22
Step-by-step explanation:
We would do the opposite so "six less" we would add 6 to 38. 6+38= 44 and "twice a number" we would divide by 2. 44 /2= 22. So the answer would be 22.
Hope this helps! :)
Answer:
Answer is 22
Step-by-step explanation:
38+6=44
44 ÷ 2= 22

A 4.0-kg cart moving due east at 9.0 m/s collides with a 3.0-kg cart moving due west. The carts stick together and come to rest after the collision. What was the initial speed of the 3.0-kg cart?
Since the carts stick together and come to rest after the collision, the initial speed of the 3.0-kg cart is 12 m/s.
Given the following data:
Mass of cart 1 = 4.0 kgVelocity of cart 1 = 9.0 m/sMass of cart 2 = 3.0 kgTo find the initial speed of the 3.0-kg cart, we would apply the law of conservation of momentum:
For a perfectly inelastic collision:
[tex]M_1V_1 - M_2V_2 = V_f(M_1 + M_2)[/tex]
When the carts stick together and come to rest after the collision, the final velocity is zero (0).
[tex]M_1V_1 - M_2V_2 = 0\\\\M_1V_1 = M_2V_2\\\\V_2 = \frac{M_1V_1}{M_2}[/tex]
Substituting the given parameters into the formula, we have;
[tex]V_2 = \frac{4(9)}{3}\\\\V_2 = \frac{36}{3}[/tex]
Initial speed = 12 m/s

I need help with this question I beeen stuck on it
Answer:
Step-by-step explanation:
The rule says that when the bases are the same (both are the same -- s) and they are divided with different powers then you subtract the power on the denominator from the power on the numerator.
s^9 ÷ s^4
s^9 is the numerator
s^4 is the denominator
s^(9 - 4)

Mike and Lilly are working together on a science project. They agreed to
meet halfway between their houses and ride their bikes to the library
together. Approximately how far will Mike and Lilly ride to the library once
they meet each other at the halfway point?
The approximate distance Mike and Lilly will have to travel between halfway point and Library is 7.8 miles.
From the graph :
Mike's coordinate = (-4, 2) Lilly's coordinate = (2, - 2) Library coordinate = (4, 6)Meeting point = Halfway point :
(x1 + x2) /2 ; (y1 + y2) / 2
X - coordinate = (-4 + 2) / 2 = - 2/ 2 = - 1
Y - coordinate = (2 + (-2)) /2 = 0/2 = 0
Hence, meeting point = (-1, 0)
The distance between meeting point and library :
Distance = √[(x2 - x1)² + (y2 - y1)²]
Distance = √[(4 - (-1))² + (6 - 0)²]
Distance = √(25 + 36)
Distance = √61 = 7.8 miles
Therefore, the distance between halfway point and library ls approximately 7.8 miles

Z-49+851=100+21z /////////////////////////////////////////////////
Answer:
z=35.1
Step-by-step explanation:
Answer:
z = 351/10 or z = 35.1
Step-by-step explanation:
*Add/subtract numbers: -49 + 851 = 802
z + 802 = 100 + 21z
*Subtract 802 from both sides
z + 802 - 802 = 100 + 21z - 802
*Simplify
z = 21z - 702
*Subtract 21z from both sides
z - 21z = 21z - 702 - 21z
*Simplify
-20z = -702
*Divide both sides by -20
- 20z/20 = - 702/- 20
*Simlify
z = 351/10 or z = 35.1

7 divided by 55, but every step must be show
Answer:
Step 1:
Start by setting it up with the divisor 7 on the left side and the dividend 55 on the right side like this:
7 ⟌ 5 5
Step 2:
The divisor (7) goes into the first digit of the dividend (5), 0 time(s). Therefore, put 0 on top:
0
7 ⟌ 5 5
Step 3:
Multiply the divisor by the result in the previous step (7 x 0 = 0) and write that answer below the dividend.
0
7 ⟌ 5 5
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (5 - 0 = 5) and write the answer below.
0
7 ⟌ 5 5
- 0
5
Step 5:
Move down the 2nd digit of the dividend (5) like this:
0
7 ⟌ 5 5
- 0
5 5
Step 6:
The divisor (7) goes into the bottom number (55), 7 time(s). Therefore, put 7 on top:
0 7
7 ⟌ 5 5
- 0
5 5
Step 7:
Multiply the divisor by the result in the previous step (7 x 7 = 49) and write that answer at the bottom:
0 7
7 ⟌ 5 5
- 0
5 5
4 9
Step 8:
Subtract the result in the previous step from the number written above it. (55 - 49 = 6) and write the answer at the bottom.
0 7
7 ⟌ 5 5
- 0
5 5
- 4 9

You are done, because there are no more digits to move down from the dividend.

The total cost in dollars, c, to purchase video games online can be found using e function c = 16.95x + 4.75, where x is the number of video games purchased. If at least 4 games but no more than 7 games are purchased online, what is the range of the function for this situation?
Answer:
72.55 ≤ x≤ 123.40
Step-by-step explanation:
c = 16.95x + 4.75,
We have to purchase a minimum of 4 games
Let x = 4
c (4) = 16.95(4) + 4.75
c(4) =67.8+4.75 = 72.55
This is the smallest amount we will spend
The most we will purchase is 7 games
Let x = 7
c (7) = 16.95(7) + 4.75
c(7) =118.65+4.75 = 123.40
This is the largest amount we will spend
The range is
72.55 ≤ x≤ 123.40

D) -2.14< root10 <|-2.8|
Step-by-step explanation:
the value for -2.14 is as plain as you can see, the negative version of 2.14.
The square root of 10 is 3.16227766.
The lines next to -2.8 is asking for the absolute value of -2.8, or the distance between that number and zero. The distance between -2.8 and 0 is positive 2.8, because distance can't be negative.
The 3 numbers taken from the explanations are -2.14, 3.16, and 2.8. Ranking them from least to greatest would give you -2.14, 2.8, 3.16, or -2.14< root10 <|-2.8|

Heather invest $3377 in a retirement account with a fixed annual interest rate of 8% compounded two times per year .how long will it take for the countdowns to reach $14,989.87?
round to the nearest whole year.
It will take 19 years for the countdowns to reach $ 14,989.87
Given that Heather invest $ 3377 in a retirement account with a fixed annual interest rate of 8% compounded two times per year, to determine how long will it take for the countdowns to reach $ 14,989.87 the following calculation must be performed:
Initial value x (1 + interest rate / compounding times) ^ (years x compounding times) = Compound interest
3377 x (1 + 0.08 / 2) ^ 2X = 14,989.87 3377 x 1.04 ^ 2X = 14,989.87 3512.08 ^ 2X = 14,989.87 X = 19
Therefore, it will take 19 years for the countdowns to reach $ 14,989.87.
