Translate the following equation into words: 5c - 4 = 11 Five, times a number minus four, is eleven. A number, times five minus four, is eleven. Five times a number, subtracted from four, is eleven. Four less than the product of five and a number, is eleven.
Answer:
Four less than the product of five and a number, is eleven.
Step-by-step explanation:
"The product of five and a number": 5c
"Four less than": - 4
"is eleven": = 11
"Four less than the product of five and a number is eleven":
5c - 4 = 11
Four less than the product of five and a number is eleven
No is cProduct of 5 and c is 5c
4 less than it means 5c-4

Your Answer is... 26.8
Step-by-step explanation:
The estimated answer is D. 27!
Hopefully this helps you! ^^
Answer:
27
Step-by-step explanation:
12.18 + 14.62= 26.80
if the number after the point is greater than 5 or equal to 5, we will add 1 to the number before the point, so now the number is 8 we will add 1 to the number before the point
26+1=27
therefore the sum of 12.18+14.62 = 27

A hotel with 80 rooms has 45 for doubles
and 35 singles. Singles can be booked in
any room, but reservations for two or
more people must be booked in double
rooms.
Let x be the number of single reservations and y
the number of reservations for two or more.
Which system of inequalities represents this
situation?
Click on the correct answer.
x ≥ 35 x + y ≤ 80
y ≤ 45 x + y ≤ 80
x≤ 35 x+y≤ 80
y≥ 45 x + y ≤ 80
Answer:
y ≤ 45
Step-by-step explanation:
First y must be less than or equal to 45.
y ≤ 45 x + y ≤ 80
And total number of reservations cannot exceed 80:
x + y ≤ 80.

y=-24-12y=-361 AB is tangent to circle O at B. The diagram is not drawn to scale. If AB=12 nd AO=15, what is the length of the radius (r)
Answer:
r = 9 units
Step-by-step explanation:
since AB is a tangent to the circle at B , then ∠ ABO = 90°
so Δ ABO is a right triangle
using Pythagoras' identity in the right triangle
OB² + AB² = AO² , that is
r² + 12² = 15²
r² + 144 = 225 ( subtract 144 from both sides )
r² = 81 ( take square root of both sides )
r = [tex]\sqrt{81}[/tex] = 9

Abc is isosceles. ab=3x-4 and bc=5x-10 what is ab

6=2x
3=x
AB= 3(3)-4
9-4
5
Answer:
ab = 5.
Step-by-step explanation:
As the 2 sides are equal in length:
3x - 4 = 5x - 10
3x - 5x = -10 + 4
-2x = -6
x = 3.
So ab = 3x-4 = 3(3)-4
= 5.
How do I solve x - 6 1/2 = 3 2/3
Pls explain ur answer and how I can improve I’m having math finals
Answer:
10 1/6
Step-by-step explanation:
First, you need to turn all the mixed numbers into improper fractions. You do this by multiplying the whole number by the denominator, adding the numerator, and then putting that number over the denominator.
So, 6 1/2 would become (6(2) + 1)/2 = 13/2. And 3 2/3 would become (3(3) + 2)/3 = 11/3.
Then, you can rewrite your equation using the improper fractions:
x - 13/2 = 11/3
Then, add 13/2 to both sides since it is being subtracted:
x = 13/2 + 11/3
Add the fractions by multiplying the denominators of each by the fraction of the other:
3(13/2) = 39/6
2(11/3) = 22/6
Add the fractions:
39/6 + 22/6 = 61/6
Simplify the fraction:
10 1/6
Answer:
10 1/6 or [tex]10\frac{1}{6}[/tex]
Step-by-step explanation:
The BEST, BASIC, FAST trick to find x in these situtations
If you have to find x in a question which is having Subtraction, then you add what number was being subtracted or what was subtracting the x or variable with the ending result. If you're doing addition, then you do subtraction in the same way.
Multiplication -> Division
Divisioin -> Multiplication
these 2 also in the same way!
Why do to do this?
Because when we will add that number with the final result, then we will get what is x, since x-that number = the last number. Try to understand, it's pretty hard to explain.
Now, solving the problem!

In a batch of 390 water purifiers, 12 were found to be defective l. What is the probability that a water purifier chosen at random will be defective? Write the probability as a percent. Round to the nearest tenth of a percent if necessary.
Answer:
3.08 percent
Step-by-step explanation:
if you do proportions, then it would go like this:
12/390 = x/100
(cross multiply)
390x = 1200
(divide both sides by 390 to get x by itself)
x = 3.07692307692
round and its about 3.08 percent

Find three consecutive even integers such that the sum of 5 and the second is multiplied by -7, the result is 11 greater than 5 times the opposite of the third
Answer:
-20, -18, -16
Step-by-step explanation:
For consecutive integer problems, it often works well to let a variable represent the middle one (or their average value).
__
Here, we can let x represent the second integer. Then the first is (x-2), and the third is (x+2). The given relation can be written as ...
(5 +x)(-7) = 11 +5(-(x+2))
-35 -7x = 11 -5x -10 . . . . . . eliminate parentheses
-36 = 2x . . . . . . . . . add 7x -1
-18 = x . . . . . . . . divide by 2
The three integers are -20, -18, -16.

each can?
Answer:
This problem gives us the total amount of cans and it also gives us the total cost and asks us to find the cost of each can when every can costs the same amount. To do this we need to $ to be on the top and the can on the bottom because we say price PER can.
