What is the solution to the inequality?
-2x - 4 ≤ 11
Thank you!
Answers
Answer:
x ≥ -15/2
Step-by-step explanation:
-2x - 4 ≤ 11
Add 4 to each side
-2x - 4+4 ≤ 11+4
-2x ≤ 15
Divide each side by -2, remembering to flip the inequality since we are dividing by a negative
-2x/-2 ≥ 15/-2
x ≥ -15/2
Answer:
x≤-7.5
Step-by-step explanation:
-2x - 4 ≤ 11
Add 4 to both sides
-2x≤15/-2
Divide
x≤-7.5

There are currently 6,210 fish in a lake. If the number of fish in the lake increased by 15 percent during the last year and 20 percent during the year before that, how many more fish are in the lake currently than in the last two years ago?
Answers
I’m pretty sure the answer should be 1,710 if not i’m sorry
Answer:
1710 fish
Step-by-step explanation:
Let the number of fish in the lake last year be 'x'
The equation becomes-
x + 15x/100=6210 (This is because 15% of x is added in x to become
6210... hope you understand)
x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400
Therefore- The number of fish last year = 5400
Now, let the number of fish in the lake 2 years ago be 'y'
The equation becomes-
y + 20y/100 = 5400 (Same logic as last time)
y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500
Therefore- Fish in the lake two years ago = 4500 fish
Difference between current and two years ago = 6210-4500
= 1710 fish

how to check : 3x+5=11
Answers
Answer:
There are two ways to check if 3x+5=11 is true:
Subtract 5 from both sides of the equation. This will isolate x on the left-hand side of the equation.
3x = 6
Divide both sides of the equation by 3. This will divide both sides of the equation by 3, which will cancel out the 3 on the left-hand side of the equation, leaving x by itself.
x = 2
You can also check if 3x+5=11 is true by plugging in 2 for x. If you do this, you will get 3(2)+5 = 6+5 = 11. Therefore, 3x+5=11 is true when x=2.

There are 233 skiers in line to ride the chair lift. If each chair seats 5 people, how many skiers will be on the last chair?
Answers
Answer:
At first we will divide 233 with 5
233/5= 46.6
So,
there will be 46.6 chairlifts occupied
After that we will subtract 233 from 46
233-46=186/5=37
So,
there will be 37 skiers on the last chair lift
Step-by-step explanation:
Answer:
3 people will be seated on the last chair.
Step-by-step explanation:
46 seats can fit 5 people perfectly. But if you multiply 46*5, it will equal 230, and that isn't the total number of skiers. So, you only need 3 more skiers to make up the total, so that means that there will be 3 skiers in the last chair.

The sides closest to us and farthest from us, with the (visible) dimensions 4 and 8 are the bases.
The area of the base(s) is/are 26 square units.
The volume of the shape is 312 square units.
Step-by-step explanation:
That base in particular with the according dimensions appears twice, meaning it can be calculated across both ways, whether it's flipped or not.
The area of the base is shown from the shape broken down: the rectangle's height (4) and the length (5) make 20 for that area, and the triangle's height (still 4) and base (8-5=3) divided by two is 6, 20+6=26.
the volume is just that 26 multiplied by 12, or 312. Or maybe 72, but probably not. try that if 312 doesn't work. I'm hungry right now, I can't think straight.
Good luck!

An isosceles triangle in which the two equal sides, labeled a, are longer than the base, labeled b. This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The perimeter of the triangle is 15.7 centimeters. The equation 2a + b = 15.7 models this information. If one of the longer sides is 6.3 centimeters, which equation can be used to find the length of the base? 6.3+b=15.7 12.6+b=15.7 2a+6.3=15.7 2a+12.6=15.7
Answers
Hey There!!
The answer to this is: isosollese triangle has 2 equal sides that are longer than legnth of base
perimiter=15.7
equation is 2a+b=15.7
so if the longer side is 6.3, wat is legnth of base
we know that identical sides are bigger so 6.3 is one of the identical sides
2a means the 2 idneical sides
2(6.3)+b=15.7
12.6+b=15.7
subtract 12.6 from btohs ides
b=3.1
Thus, answer is base=3.1 cm

Answer:
The value of y is \(-1.33...\)
Step-by-step explanation:
WKT, the given equation is \(\frac{-1}{2} =\frac{3}{8} y\)
Here, y is a variable.
Now, to solve the equation,
we need to multiply \(\frac{8}{3}\) on both sides of the given equation, in order to get the values of y.
That is, \(\frac{-1}{2}\) × \(\frac{8}{3} =\frac{8}{3}\) × \(\frac{3}{8} y\)
⇒\(-\frac{1}{2}\) × \(\frac{8}{3}= y\)
⇒\(-\frac{8}{6}=y\)
⇒\(y=-\frac{4}{3}\)
or \(y=-1.333\)
Therefore, the value of y is \(-1.33...\).

Help!!!! the integer that makes the following addition sentence true.

Answers
As you can see the end result will end up with -16
Answer:
-17
Step-by-step explanation:
I will represent the question mark with the variable \(x\).
\(x - 11 + 12 = -16\)
To solve for \(x\), we need to isolate it.
To do this, subtract 12 from both sides.
\(x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28\)
Then, add 11 to both sides.
\(x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17\)
\(x = -17\)
So, the integer that makes the equation true is -17.

Step-by-step explanation:
Answer:
\(7^{3}\) = 343
4 cubed = 64
\(9^{2}\) = 81
\((3.5)^{2}\) = 12.25
Step-by-step explanation:
\(7^{3}\) is the same thing as 7 * 7 * 7.
7 * 7 = 49
49 * 7 = 343
4 cubed can be written as \(4^{3}\), which is the same as 4 * 4 * 4.
4 * 4 = 16
16 * 4 = 64
\(9^{2}\) is the same as 9 * 9.
9 * 9 = 81
\((3.5)^{2}\) is the same as 3.5 * 3.5.
