Answer:
(-4,-4)
Step-by-step explanation:
Make a number line and mark the points that represent the following values of x. 5x<12
Answer:
The answer is: x < 2.4
Step-by-step explanation:
5x < 12
If we divide both sides by 5, we get an equation like this:
x < 12/5
Then we can convert that fraction to a decimal and we get this!
x < 2.4
Finally, in order to draw it on the number line, we need to do this:
Find 2.4 on the number line, then draw an open circle on that 2.4. Then, attach an arrow going from that circle all the way to the left of the number line! The circle and arrow represents the fact that "x" is not equal to 2.4, but it is smaller. If it was equal to 2.4 or smaller, then the open dot would have to be a closed dot!!!!

Cups cost x dollars each. Mugs cost (x + 2) dollars each. (a) Write down an expression, in terms of x, for the total cost of 12 cups and 6 mugs. ............................................................................... dollars (2) (b) The total cost of 12 cups and 6 mugs is 57 dolllars.
work out the cost of 1 cup
Answer:
a. [tex]18x + 12[/tex]
b. $2.50
Step-by-step explanation:
a. If there are 12 cups and 6 mugs, and one cup is x and 1 mug is x+2, then multiply to get 18x + 12
b. Use the previous equation 18x+12=57 to get your answer. First move the 12 over to change the 57 to a 45. Then divide 45/18 to get 2.50 as you answer.

Simplify this equation 8x-4+6x+15
Answer:
14x + 11
Step-by-step explanation:
Collect all the like terms together.
Positive 8x and positive 6x both have an x so after adding them together you get 14x. Negative 4 and positive 15 are also like terms so after adding them together you get positive 11.
The final answer being 14x + 11
Answer:
14x + 11
Step-by-step explanation:
8x - 4 + 6x + 15 =
8x + 6x + 15 - 414x + 15 - 414x + 11simplify this equation is 14x + 11
What is the length of PR?
A. 7
B. 8
C. 6
D. 9
Answer:
C
Step-by-step explanation:
The triangles are similar by the AA postulate, thus the ratios of corresponding sides are equal, that is
[tex]\frac{AB}{PQ}[/tex] = [tex]\frac{AC}{PR}[/tex] , substitute values
[tex]\frac{20}{5}[/tex] = [tex]\frac{24}{PR}[/tex] ( cross- multiply )
20PR = 120 ( divide both sides by 20 )
PR = 6 → C

=======================================================
Explanation:
"six subtracted from x" translates to "x-6"
So the word problem updates to "x-6 is less than -15"
Then we replace the "is less than" with "<" without quotes.
---------
Extra info: If you want to solve for x, then we add 6 to both sides like so
x-6 < -15
x-6+6 < -15+6
x+0 < -9
x < -9
So any number smaller than -9 will work in place of x.
A farmer needs to purchase a rainwater harvesting tank and is deciding on the shape. He needs a tank that can hold at least 90 cubic feet of water. Select all the tanks that have a capacity of at least 90 cubic feet.
Answer:
Tank A and Tank D
Step-by-step explanation:
Got it right
The tanks that have the capacity more than 90 cu.ft is Tank A and C.
What is Volume?Volume is the amount of space occupied by a three dimensional object, it is represented in cubic units.
The volume of a Cylinder is given by
V = πr²h
The Volume of a Cone is given by
V= πr²h/3
The volume of the composite figure in Tank A and D,
Volume = Volume of cylinder + Volume of Cone
Tank A :
Volume = πr²h + πr²h/3
Volume = ( π * 2.5² * 4 ) + ( π *2.5² *2 )/3
Volume = 91.58 cu.ft
Tank B :
Volume = πr²h/3
Volume = π * 4² *5 /3
Volume = 83.7 cu.ft
Tank C
Volume = πr²h
Volume = π * 2² * 6
Volume = 75.36 cu.ft
Tank D:
Volume = πr²h + πr²h/3
Volume = π * 3²*3 + π *3²* 3 /3
Volume = 113.04 cu.ft

Find the solutions to the equation 102x 11 = (x 6)2 – 2. which values are approximate solutions to the equation? select two answers. –9.6 –7.4 –4.6 –2.4 0.6
The approximate soluton of the equation 102x + 11 = (x + 6)² – 2 is 0.6. Then the correct option is E.
What is a quadratic equation?It is a polynomial that is equal to zero. Polynomial of variable power 2, 1, and 0 terms are there. Any equation having one term in which the power of the variable is a maximum of 2 then it is called a quadratic equation.
The quadratic equation is given below.
102x + 11 = (x + 6)² – 2
Open square, we have
102x + 11 = x² + 12x + 36 – 2
x² – 90x + 23 = 0
By the formula, we have the value of x
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}\\\\x = \dfrac{90 \pm \sqrt{(-90)^2}-4*1*23}{2*1}\\\\x = 89.74, 0.256[/tex]
The approximate soluton of the equation 102x + 11 = (x + 6)² – 2 is 0.6. Then the correct option is E.
