Simplify the expression:
(8-5)2.3-8=2
Answer:
6.9−8=2
Step-by-step explanation:
(8−5)2.3−8=2
Subtract 5 from 8 to get 3.
3×2.3−8=2
Multiply 3 and 2.3 to get 6.9.
6.9−8=2
Subtract 8 from 6.9 to get −1.1.
−1.1=2
Compare −1.1 and 2.

r/3+2=21 solve for r
Answer:
r=63
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
r/3-(21)=0 r
Simplify —

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

A concrete mixing machine weighing 800 pounds needs to be loaded with rocks and sand. Trucks carrying 120 pounds of sand
and 30 pounds of rocks will be used to load the machine. In order for the machine to function properly, the combined weight
of the machine and the mixing load cannot exceed 2,800 pounds.
Which inequality describes the restriction on truck loads, x, to ensure the mixing machine functions properly?
A. 120x+800 > 2,800
B. 150x + 800 > 2 2,800
C. 800x + 150 < 2,800
D. 150x+800 < 2,800
The inequality to ensure the mixing machine functions properly is,
D. 150x + 800 < 2800
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
From the given information and the statement that the combined weight should not exceed 2800 pounds the inequality that represents the number of loads it can take to ensure the mixing machine functions properly is,
150x + 800 < 2800.

If f(x) = -2 and g(x) = 2x² + x-3, find (f +9)(x).
Answer:
(f + g)(x) = 2x² + x - 5
Step-by-step explanation:
Given
[tex]f(x) = -2[/tex]
[tex]g\left(x\right)\:=\:2x^2+\:x-3[/tex]
To determine
(f + 9)(x) = ?
Using the formula
(f + g)(x) = f(x) + g(x)
substituting f(x) = -2 and g(x) = 2x² + x - 3
= -2 + 2x² + x - 3
= 2x² + x - 5
Therefore, we conclude that:
(f + g)(x) = 2x² + x - 5

-7y = -77 solve for y
Answer:
y is 11
Step-by-step explanation:
-7y = -77
Divide both sides by -7
-7y/-7 = -77/-7
Since it's -77/-7, a negative divided by a negative gives us a positive output.
Y=11 is our final answer.
if the area of an equilateral triangle is 24 square root 3 metres square then its perimeter is?
Answer:
6√24 or 29.39metres
Step-by-step explanation:
Area of a triangle is bh/2
The perimeter of an equilateral triangle is 3b
This equilateral triangle can be imagined as two adjoining 30-60-90 triangles. Together, their area is the given 24√3 m²
The base of the individual triangle is √24. The height is √24√3. Multiplying those factors, we get the given area, a proof of sorts, but mure importantly, we can calculate the length of the hypotenuse as 2√24.
sin(30°) = 0.5
√24/(0.5) = 2√24
That is the length of the side of the original equilateral triangle.
The perimeter is 3 times the length of the side:
(3)(2√24) = P
6√24 meters is the perimeter.
What is the value of x in the equation below?
3(12x-24) = 16
A) 2
B) 6
C) 8
D) 10
ANSWER: B) 6
Answer:
3(12x - 24) = 16 (use the distributive property)
36x - 72 = 16 (add 72 to both sides to get the x-term alone)
36x = 88 (divide both sides by 36 to isolate x)
x = 2.4 (the four is repeating. that's the exact answer.)
I would say the answer is A because 2.4 is close to 2 than any of the other answers.

Mrs kin picked some tomatoes from her garden. She use 5/9 of her tomatoes to make pasta sauce. Then she used 5/8 of the remainder to make a salad and saved the rest for the next day. What fraction of the tomatoes did mr kin saved
Answer:
1/6 of the tomatoes
Step-by-step explanation:
So first, after she uses 5/9 she has 1 - 5/9 = 4/9 of her tomatoes left. Then, she uses 5/8 of that 4/9 to make a salad, so she used 5/8 * 4/9 = 5/18 of her tomatoes overall. That means that she has 4/9 - 5/18 = 8/18 - 5/18 = 3/18 = 1/6 of her tomatoes saved.
