1. Select all the equations that have no solution.
a. +6=5+
b. -2(−3)=-2+6
c. 4−4=3+2
d. 4(+1)=3(+2)
e. 5−3=-3+4
Answer:
a, and e.
Step-by-step explanation:
x+6=5+x has no solution. When you subtract 6 from both sides, you get x=-1+x. We know that x doesn't equal -1+x, so this equation has no solution.
-2(x-3)=-2x+6 has a solution. When you distribute, you get -2x+6=-2x+6.
4-4x=3x+2 has a solution. Subtract 4 from both sides to get -4x=3x-2. Subtract 3x from both sides to get -7x=-2, then divide -2 by -7 to get x=0.285714285714. This equation has a solution.
4(x+1)=3(x+2) has a solution. Distribute to get 4x+4=3x+6. Subtract 4 from both sides to get 4x=3x+2. Subtract 3x from both sides to get x=2. This equation has a solution.
5-3x=-3x+4 has no solution. Subtract 5 from both sides to get -3x=-3x-1. We know that -3x does not equal -3x-1, so we can determine that this equation has no solution.
Answer:
a and e has no solution
Step-by-step explanation:
A) x + 6 = x +5
Subtract x from both sides
x + 6 - x = x + 5 - x
6 = 5 which is not true.
So, this equation has no solution
d) 5 - 3x = -3x + 4
Add 3x to both sides
5- 3x + 3x = -3x + 4 + 3x
5 = 4 which is not true.
So, no solution

HELP ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
l = 14
Step-by-step explanation:
The perimeter of a rectangle is
P =2(l+w)
The width is x-6
w = x-6
The length is 8 units longer than the width
l = w+8
l = x-6+8
l = x+2
We can substitute this into the equation for Perimeter, which is given as 40
40 = 2(x+2 + x-6)
Combine like terms
40 =2 (2x-4)
Divide by 2
40/2 = 2/2 (2x-4)
20 = 2x-4
Add 4 to each side
20+4 =2x-4+4
24 = 2x
Divide by 2
24/2 =2x/2
12=x
We want to know the length
l = x+2
l =12+2
l = 14
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Multiply the length that you have been given by 2
2: Then, subtract the result from the perimeter.
3: You now have the total length for the remaining 2 sides.
4: Width or height is the number divided by 2.
In a set of 1,000 integers from 1 to 1,000, an integer chosen at random on a single trial should be an integer from 1 to 25 about 25 out of every 1,000 trials, or one out of every 40 integers selected. A sample of 5 integers selected is shown. Does this sample represent the general rule for picking an integer from 1 to 25 in the population of integers from 1 to 1,000?
A.Yes - the sample is representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be none or zero.
B. No - the sample is not representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be at least 10.
Reminder: Please do not just say the answer, make sure to include your work on how you got the answer!

Answer:
10%
Step-by-step explanation:
1/20 = 5/100
5/100 = 5%
1/100 = 1%
2/20 = 10/100
10/100 = 1 x 10 = 10%

Answer:
A
Step-by-step explanation:
Answer:
a
Step-by-step explanation:
Please help me if you can. Please also write how you got the answer thank you.
First state your variables:
a = Andile
Everything is related to Andile and therefore we do not need to make this equation more difficult by adding in more variables.
a + (a - 40) + 2(a - 40) = 380
Expand brackets and simplify:
2a - 40 + 2a - 80 = 380
4a - 120 = 380
4a = 500
Then solve for 'a' by dividing by both sides:
a = $125
Now we know Andile's pay we can find Taylor's quite easily:
t = a - 40
t = 125 - 40
t = $85
Taylor earned $85.
