Answer:
x = - 26
Step-by-step explanation:
2x - 11 - 3x = 15
- x - 11 = 15
- x = 15 + 11
- x = 26
x = - 26
Answer: x = -26
Step-by-step explanation:
How to solve your problem
2x-11-3x=15
Solve
1
Combine like terms
2x - 11 3x +15
-x -11 = 15
Add
11
to both sides
-x-11=15
-x-11+11 = 15 + 11

Explain how to use a pattern to find the product of a decimal
Answer: Remove, Multiply, Add (RMA)
Step-by-step explanation:
I'll share a method I use. it is removed, multiply, and add. first, you have to remove the decimals from the problem, multiply them, and add the decimals back into the problem. count the number of how many numbers are behind the decimal. for example, let's take 3. after you multiply, count three spaces to the left and place the decimal. let's take 3.12 x 2.7. first, remove the decimals. after you do that, you're left with 312 x 27. do the multiplication, and then count the number of how many numbers are behind the decimals. so, that would be three. your answer for the mutiplication problem is 8,424. since there are three spaces, you would count one, two three. to the left of 8,424. therefore, the answer is 8.424

Help!!!! the integer that makes the following addition sentence true.
? + (-11) + 12 + =-16
Answer:
-17
Step-by-step explanation:
I will represent the question mark with the variable [tex]x[/tex].
[tex]x - 11 + 12 = -16[/tex]
To solve for [tex]x[/tex], we need to isolate it.
To do this, subtract 12 from both sides.
[tex]x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28[/tex]
Then, add 11 to both sides.
[tex]x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17[/tex]
[tex]x = -17[/tex]
So, the integer that makes the equation true is -17.
Tyee goes out to lunch. The bill, before tax and tip, was $14.20. A sales tax of 6% was added on. Tyee tipped 18% on the amount after the sales tax was added. How much tip did he leave? Round to the nearest cent
Answer:
$2.71
Step-by-step explanation:
Original total: $14.20
Add tax: 1.06 × $14.20 = $15.05
18% of total with tax = 18% of $15.05 = 0.18 × $15.05 = $2.71
8. Consider a $2 principal investment with a 10% annual simple interest rate.
a. Write and graph the simple interest equation that represents the situation.
b. What does the y-intercept represent?
c. What does the slope of the graph represent?
d. What does the point (5, 3) represent on the graph?
Answer:
(I can only really help with number 2, I'm sorry :(((
2.The y-intercept of a line is the value of y where the line crosses the y-axis. In other words, it is the value of y when the value of x is equal to 0.

Consider the function below. Find f(8)
Answer: The First one isn't valid
The second one is equal to 9
Answer:
Step-by-step explanation:
Substitute 8 for x
3(8) - 1
Solve:
3 x 8 = 24
24 - 1 = 23
Next, substitute for x in the inequality with the answer you just made. See if it's true.
23 [tex]\leq[/tex] 2
The inequality is NOT TRUE
Same thing for the next one
1/2(8) + 5
Solve:
1/2 x 8 = 4
4 + 5 = 9
Substitute for x in the inequality with the answer you just made. See if it's true.
9 > 2
This inequality is TRUE

Logan is 5 feet tall and his shadow is 8 feet long. At the same time of day, a tree’s shadow is 32 feet long. What is the height of the tree?
29 feet
51 feet
20 feet
24 feet
Answer: 29 ft because if his shadow is 8 ft that tells me that the equation would be less and and 8-5=3 so 32-29=3

Juan cuts a piece of rope that is 1/6 meter long into 2 equal pieces.
What is the length of each shorter piece of rope?
Enter your answer as a fraction in simplest form by filling in the boxes.
[tex]\frac{x}{y} \\[/tex]
Answer:
1/12 a meter long
Step-by-step explanation:
You have to multiply The Denominator by the amount of rope your cutting making it which in your case its 2 pieces so multiply 2 by 6 equals 12 and so replace 6 with 12 and that's your answer. good luck on your test or whatever it is!
Find the diagonal of the box, AD, using the Pythagorean Theorem twice - 1. To find BD and 2. To find AD.
AB = 12 in
BC = 18 in
CD = 4 in
Show all steps for findin the diagonal of the box above using the formula instead of the Pythagorean Theorem twice.
Answer:
BD = √(18² +4²) = √340; AD = √(12² +(√340)²) = 22AD = √(12² +18² +4²) = 22Step-by-step explanation:
You want the space diagonal of the given box (a) using the Pythagorean theorem twice, and (b) using the formula.
Pythagorean theorem twiceThe length of BD can be found from ...
BD² = BC² +CD²
BD² = 18² +4² = 340
BD = √340 ≈ 18.439
and
AD² = AB² +BD²
AD² = 12² + 340 = 484
AD = √484 = 22
The lengths of the face and space diagonals are ...
BD = √340 ≈ 18.439AD = 22FormulaNo formula is given as part of the problem statement. We can simplify the above calculations to get ...
AD² = AB² +BD²
AD² = AB² +BC² +CD²
AD = √(AB² +BC² +CD²) . . . . . . a reasonable formula
AD = √(12² +18² +4²) = √(144 +324 +16) = √484
AD = 22

How to use a pattern to find the product of a decimal
Answer:
A decimal sequence is a set of decimals that follow each other in order, and we use a rule, or pattern, to go from one number to the next. To find the rule for a sequence, we take two consecutive numbers and subtract them.
Answer:
Step-by-step explanation:
So I don't know if this will help or is the answer that you're looking for but here:
If you're multiplying a decimal by 1, it obviously stays the same.
ex: 1 x 0.25 = 0.25
If you multiply by 10 then you move the decimal place once to the right, as it gets bigger
ex: 10 x 0.25 = 2.5
you can do this for any number:
10 x 3.44 = 34.4
you can also use any power of 10.
10^2/100
100 x 2.75 = 275/275.0

Answer: 187
Step-by-step explanation:
I don't think this might be right, but I rounded 1.63 gallons to 1.60 gallons. After, I decided to divide that bye the population of the
country, (300 million), which gave me 187.5. I then rounded it to 187.
Was a bit confused on this myself, but hopefully its right.

The photographer wants to mat his picture on a piece of cardboard. He is not sure if the cardboard is the right size. He has determined that the height (h) and the width (w) of the cardboard will be the right size if it satisfies the equation w-4/h-4 = 4/3. If the cardboard's height is 7, what is the width?
Answer:
8
Step-by-step explanation:
Since the cardboard’s height is 7, and 7-4 is 3, we can assume the width would be something - 4 = 4. 8-4 is 4, hence the answer is 8.

Death Valley, California, is located 282 feet below sea level.
Which equation best represents the depth of Death Valley in feet?
Answer:
Step-by-step explanation:
Even though death valley is at -282 feet in relation to sea level, it's 282 feet away in distance. So even though the distance is in a different/negative direction, it's still an ACTUAL distance, and we call that absolute value.
