If using the method of completing the square to solve the quadratic equation
22 + 15x – 11 = 0, which number would have to be added to "complete the
square"?
Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
22+15x−11=0
Step 1: Simplify both sides of the equation.
22+15x−11=0
22+15x+−11=0
(15x)+(22+−11)=0(Combine Like Terms)
15x+11=0
15x+11=0
Step 2: Subtract 11 from both sides.
15x+11−11=0−11
15x=−11
Step 3: Divide both sides by 15.

The Johnson and Sloan families went to Taco Mania for lunch. The Johnsons bought 3 burrito meals and 4 taco meals for $48. The Sloans bought 6 burrito meals and 2 taco meals for $60. How much does each meal cost?
Answer:
Each burrito meal cost 8$
Each taco meal cost 6$
Step-by-step explanation:
Johnsons= 3b +4t =48
Sloans= 6b+2t=60
multiple johnsons by -2
so, now the johnsons are -6b+-8t=-96
add that to the sloans so, -6b+6b-8t+2t=-96+60
the b's cancel eachother out, so you are left with -6t= -36
divide each side by -6 and you will get t=6
then you can pick either formula, lets say sloans this time
so, 6b + 2(6)=60 so, 6b+12=60, subtract 12 from each side, to get 48
so 6b=48, divde each side by 6 and you will get b=8
Step-by-step explanation:
Answer:
Tacos-6
Burritos-8
Step-by-step explanation:
Multiply the first equation by -2,and multiply the second equation by 1.
−2(3b+4t=48)
1(6b+2t=60)
Becomes:
−6b−8t=−96
6b+2t=60
Add these equations to eliminate b:
−6t=−36
Then solve−6t=−36for t:
−6t=−36
−6t
−6
=
−36
−6
(Divide both sides by -6)
t=6
Now that we've found t let's plug it back in to solve for b.
Write down an original equation:
3b+4t=48
Substitute6fortin3b+4t=48:
3b+(4)(6)=48
3b+24=48(Simplify both sides of the equation)
3b+24+−24=48+−24(Add -24 to both sides)
3b=24
3b
3
=
24
3
(Divide both sides by 3)
b=8
Answer:
b=8 and t=6
Simplify the expression: 4s + 5t + 6 - 4t

Write a simplified equation to solve for X.
Using the equation, solve for x
Answer:
x = 40
Step-by-step explanation:
x + 100 + x = 180 {Straight line angles}
2x + 100 = 180 {subtract 100 from both sides}
2x = 180 - 100
2x = 80 {Divide both sides by 2)
x = 80/2
x = 40
Answer:
x=40
Step-by-step explanation:
2x+100=180
2x=180-100
2x=80

If Earth's total mass is 6 x 10^24 kg, what proportion of this is lost every year?
Step-by-step explanation:
This is well within the mass uncertainty of 0.01% (6×1020 kg), so the estimated value of Earth's mass is unaffected by this factor. Mass loss is due to atmospheric escape of gases. About 95,000 tons of hydrogen per year (3 kg/s) and 1,600 tons of helium per year are lost through atmospheric escape.

You roll 2 fair 6-sided dice. What is the probability of rolling a sum of 7 or more?
18/36 or 1/2
20/36 or 5/9
19/39
21/36 or 7/12
Answer:
here we have rolled two dice. So total no. of possible outcomes will be 6^2=36. These are (1,1),(1,2),(1,3),(1,4),(1,5),(1,6),(2,1),(2,2),(2,3),(2,4),(2,5),(2,6),(3,1),(3,2),(3,3),(3,4),(3,5),(3,6),(4,1),(4,2),(4,3),(4,4),(4,5),(4,6),(5,1),(5,2),(5,3),(5,4),(5,5),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5),(6,6).
Now, among these cases the cases where the sum is seven for (1,6), (2,5), (3,4), (4,3), (5,2), (6,1) i.e. there are 6 cases.
Now, it is time to calculate the probability.
The required probability is,
p = (No. of cases favorable for the event)/(Total no. of cases)

Answer:
Apple Pie cost $8
Lemon Meringue Pie = $15
Step-by-step explanation:
Creating some variables:
A = apple pie
L = lemon meringue pie
We have two equations:
11A + 1L = 103
11A + 12L=268
You can use elimination or the substitution method to solve. I will be using substitution method.
Solve the first equation for L:
11A + 1L = 103
subtract 11A to both sides
L = 103 - 11A
Plug this into the second equation
[tex]11A + 12(103-11A) =268[/tex]
distribute the 12
[tex]11A + 1236 - 132A = 268[/tex]
combine the A and subtract the 1236
[tex]-121A = -968[/tex]
Divide -968 by -121
A = 8
Next plug this 8 back into one of the two original equations above:
[tex]11(8) + 1L =103[/tex]
[tex]88+L=103[/tex]
subtract 103 by 88
L = 15
Answer:
[tex]A=8[/tex], [tex]L=15[/tex]
Step-by-step explanation:
For the sake of time Apple pies will be represented by [tex]A[/tex] and Lemon will be represented by [tex]L[/tex]
Based on the information given it is clear that:
[tex]11A+1L=103[/tex]
[tex]11A+12L= 268[/tex]
We can rearrange the first equation to solve for [tex]A[/tex], in terms of [tex]L[/tex]
[tex]11A+1L=103[/tex]
subtract [tex]1L[/tex] form both sides
[tex]11A=103-L[/tex]
Now let's input this into the second equation to solve for [tex]L[/tex]
[tex](103-L)+12L=268[/tex]
combine like terms
[tex]11L+103=268[/tex]
subtract [tex]103[/tex] from both sides
[tex]11L=165[/tex]
divide both sides by [tex]11[/tex]
[tex]L=15[/tex]
Now input this value into the first equation for [tex]L[/tex]
[tex]11A+15=103[/tex]
subtract [tex]15[/tex] from both sides
[tex]11A=88[/tex]
divide both sides by [tex]11[/tex]
[tex]A=8[/tex]

Answer:
500 bricks.
Step-by-step explanation:
There are 250 bricks used to build a wall that is 20 feet high how many bricks will be used to build a wall is 40 feet high?
To solve e the above question, we have:
20 feet high = 250 bricks
40 feet high = x bricks
Cross Multiply
20 feet × x bricks = 40 feet × 250 bricks
x bricks = 40 feet × 250 bricks/20 feet
x bricks = 500 bricks
Therefore, 500 bricks will be used to build a wall is 40 feet high.

Answer:
24 = x
Step-by-step explanation:
You use Pythagorean theorem. Since the normal equation is [tex]a^{2} + b^{2} =c^{2}[/tex], you already have the [tex]c^{2}[/tex] and another side which can be [tex]a^{2}[/tex] or [tex]b^{2}[/tex].
Because you have the hypotenuse and a side , your equation looks like this now: [tex]7^{2} +b^{2} = 25^{2}[/tex]
and when you solve for be you just subtract [tex]25^{2} -7^{2}[/tex] to get 24.
