3x -10+ 4x= -2 (x-4) +9
Answer:
x = 3
Step-by-step explanation:
Step 1: Write equation
3x - 10 + 4x = -2(x - 4) + 9
Step 2: Solve for x
Distribute -2: 3x - 10 + 4x = -2x + 8 + 9Combine like terms: 7x - 10 = -2x + 17Add 2x to both sides: 9x - 10 = 17Add 10 to both sides: 9x = 27Divide both sides by 9: x = 3Step 3: Check
Plug in x to verify it's a solution.
3(3) - 10 + 4(3) = -2(3 - 4) + 9
9 - 10 + 12 = -2(-1) + 9
-1 + 12 = 2 + 9
11 = 11

6-7x= 7x- 9x - 4
The value of x is _.
Answer:
x = 2
Step-by-step explanation:
Step 1: Write equation
6 - 7x = 7x - 9x - 4
Step 2: Solve for x
Combine like terms: 6 - 7x = -2x - 4Add 7x to both sides: 6 = 5x - 4Add 4 to both sides: 10 = 5xDivide both sides by 5: 2 = xRewrite x = 2Step 3: Check
Plug in x to verify it's a solution.

V = 168 cubic in.
When you multiply a whole number by this number, n, it will decrease the
value.
Which of the following values could represent n?
I. 13
3
un
II.
III. 0.98
IV. 1.05
Answer:III/ 0.98
Step-by-step explanation: if you multiply a number by a decimal (not like 1.55, since that would increase the value since there is a whole) it will decrease.
Answer:
0.98
Step-by-step explanation:
because if you do 6 x 0.98 you get 5.88
You have $70 in your bank account. Each week you plan to deposit $7 from your allowance and $10 from your paycheck. The equation b = 70 + (10 + 7)w gives the amount b in your account after w weeks. How many weeks from now will you have $185 in your bank account?
Answer:
After 7 weeks from now you will have $185 in your bank account.
Step-by-step explanation:
We are given that you have $70 in your bank account. Each week you plan to deposit $7 from your allowance and $10 from your paycheck. The equation b = 70 + (10 + 7)w gives the amount b in your account after w weeks.
The equation is given by;
b = 70 + (10 + 7)w
Now, in the question, it is given that you have $185 in your bank account, that means;
$185 = $70 + $17w
Finding the value of w(weeks);
$17w = $185 - $70
$17w = $115
w = [tex]\frac{\$115}{\$17}[/tex]
w = 6.76 weeks or 7 weeks (approx).
Hence, after 7 weeks from now you will have $185 in your bank account.
Jenny is solving the equation 3 x + 5 = 4 x + 2 using algebra tiles. She cannot decide if she should add 3 negative x-tiles or add 2 negative unit tiles to both sides first. Which explains which Jenny should do first?
A.She should add 3 negative x-tiles first because that is the only way to isolate the variable.
B.She should add 2 negative unit tiles first because that is the only way to get to the correct solution.
C.She can do either one first because zero pairs will be created to isolate the variable either way.
D.She should do neither one first because the first step is to add 4 negative tiles to both sides.
Answer:
Step-by-step explanation:
A
Answer:
A She should add 3 negative x-tiles first because that is the only way to isolate the variable. Is the correct answer

Please help on this: Given: 4c-d = f, d = c-e, f = d + e; Prove: 3c = d
Answer:
Step-by-step explanation:
Given the equations:
4c-d = f ....... 1
d = c-e....... 2
f = d + e....... 3
Substitute 2 into 1
4c -(c-e) = f
4c -c + e =f
3c + e = f ......4
Substitute equation 3 into 4:
3c+e = d+e
subtract e from both sides
3c+e-e = d+e-e
3c = c (Proved)

Suppose that 50% of the subscribers of a cable television company watch the shopping channel at least once a week. The cable company is trying to decide whether to replace this channel with a new local station. A survey of 100 subscribers will be undertaken. The cable company has decided to keep the shopping channel if the sample proportion is greater than 0.585. What is the approximate probability that the cable company will keep the shopping channel, even though the true proportion who watch it is only .50? (Round the answer to four decimal places.)
Answer:
The probability is [tex]P( p > 0.585) = 0.044565 [/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.50
The sample size is n = 100
Gnerally the mean of the sampling distribution is
[tex]\mu_x = 0.50[/tex]
Generally the standard deviation of the sampling distribution is
[tex]\sigma = \sqrt{\frac{p(1- p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{0.5 (1- 0.5)}{100} }[/tex]
=> [tex]\sigma =0.05[/tex]
Generally the approximate probability that the cable company will keep the shopping channel
[tex]P( p > 0.585) = P(\frac{p- \mu_{x}}{\sigma } > \frac{0.585 - 0.50}{0.05} )[/tex]
Generally [tex]\frac{p- \mu_{x}}{\sigma } = Z (The \ standardized \ value \ of p )[/tex]
=> [tex]P( p > 0.585) = P(Z > 1.7 )[/tex]
From the z-table the probability of (Z > 1.7 ) is
[tex]P(Z > 1.7 ) = 0.044565[/tex]
So [tex]P( p > 0.585) = 0.044565 [/tex]

Answer:
3(x+4)=36 is the same as 3x+12=36
If 3x+12=36, that means x=8

Answer:
83
Step-by-step explanation:
All sides of a triangle combined equal 180 so you would add the values you have and then subtract it from 180
Step-by-step explanation:
We know that:-
All angles of a triangle sum up to give 180°.
So, According to Question,
[tex]20 + 87 + x = 180[/tex]
[tex]107 + x = 180[/tex]
[tex]x = 180 - 107[/tex]
[tex]x = 73[/tex]
So, x = 73° is the answer.
