Answer:
x = 2
Step-by-step explanation:
7(3x + 5) - x = 75
1. Distributive property
multiply 7 by whatever is in the parenthesis
7*3x + 7*5 - x = 75
21x + 35 - x = 75
2. Combine like terms
21x - x = 20x
20x + 35 = 75
3. Subtract 35 on both sides
20x + 35 - 35 = 75 - 35
20x = 40
4. Divide both sides by 20 since u want to isolate the variable
20x/20 = 40/20
x = 2
And thats ur answer
Hope this helped!

One card is selected at random from a deck of cards. Determine the probability that the card selected is a card greater than 3 and less than 8.
Answer:
4/13
Step-by-step explanation:
Count all cards that are 4, 5, 6, and 7 (each of 4 different suits) so the number of cards that is greater than 3 and less than 8 = 4(4) = 16.
There are 52 cards in a standard deck of cards.
P(greater than 3 and less than 8)
= 16/52
= 4/13

Answer:
7
Step-by-step explanation:
If you notice each container has 4 balls
3 = 12
6 = 24
10 = 40
So, this means 1 container = 4 balls
x = 28
Divide by 4
28/ 4 = 7
Pleaee gimme brainliest
Answer:
7
Step-by-step explanation:
theres a loop of 4 balls per container
3 divide 12 = 4 balls
6 divide 24 = 4 balls
? divide 28 = 4 balls
10 divide 40 = 4 balls
when you divide its like dividing the balls into the containers so if you look at ? divide 28 = 4 balls it would equal 7
ex
1 divide 28 = 28 no
2 divide 28 = 13 no
3 divide 28 = 27.5 no
4 divide 28 = 7 yes 4 goes into 7
The sides of a rectangle are 2x + 3 and 14. What are 2 expressions that represent the area of the rectangle?
Answer:
28x+42
14(2x+3)
Step-by-step explanation:
Area of a rectangle is lenght times width
A = L * W
So
14(2x+3)
28x+42
Solve the polynomial equation by factoring. x^3+2x^2-9x-18=0
Answer:
This can be factored to (x + 3)(x - 3)(x + 2) = 0
So x is equal to 3, -3 and -2
Step-by-step explanation:
x³ + 2x² - 9x -18 = 0
Let's try dividing by (x + 3) as that looks like it might be a factor. We'll use long division:
x² - x - 6
x + 3 } x³ + 2x² - 9x -18
x³ + 3x²
-x² - 9x
-x² - 3x
-6x - 18
-6x - 18
0
Perfect! So (x + 3) is a factor, giving us:
(x + 3)(x² - x - 6)
the remaining quadratic can be factored more easily:
(x + 3)(x² - x - 6)
= (x + 3)(x² + 2x - 3x - 6)
= (x + 3)(x[x + 2] - 3[x + 2])
= (x + 3)(x - 3)(x + 2)
Now we can solve it easily as we know that's equal to zero, so x can be equal to 3, -3, and -2

For the point P(6,8) and Q(11,11), find the distance d(P,Q) and the coordinates of the
midpoint M of the segment PO.
What is the distance?
(Simplify your answer. Type an exact answer, using radicals as need.)
Answer:
The distance of PQ = [tex]\sqrt{34}[/tex]
Step-by-step explanation:
Explanation:-
Given that the points are P(6,8) and Q(11,11)
Distance formula
PQ = [tex]\sqrt{x_{2}-x_{1} )^{2} +(y_{2} - y_{1})^{2} }[/tex]
= [tex]\sqrt{11-6)^{2} +(11-8)^{2} }[/tex]
= [tex]\sqrt{(5)^{2}+(3)^{2}} }[/tex]
= [tex]\sqrt{25+9}[/tex]
= [tex]\sqrt{34}[/tex]

Question :-
A cylinder has a radius of 6 in and a height of 10 in. What is the surface area of this cylinder?Answer :-
The surface area of the cylinder is 602.88 in².[tex] \rule{180pt}{3pt}[/tex]
Diagram :-
[tex]\setlength{\unitlength}{1mm}\begin{picture}(5,5)\thicklines\multiput(-0.5,-1)(26,0){2}{\line(0,1){40}}\multiput(12.5,-1)(0,3.2){13}{\line(0,1){1.6}}\multiput(12.5,-1)(0,40){2}{\multiput(0,0)(2,0){7}{\line(1,0){1}}}\multiput(0,0)(0,40){2}{\qbezier(1,0)(12,3)(24,0)\qbezier(1,0)(-2,-1)(1,-2)\qbezier(24,0)(27,-1)(24,-2)\qbezier(1,-2)(12,-5)(24,-2)}\multiput(18,2)(0,32){2}{\sf{6 \: in}}\put(9,17.5){\sf{10 \: in}}\end{picture}[/tex]
Solution :-
As per the provided information in the given question, we have been given that the radius of the cylinder is 6 in. The height of the cylinder is 10 in. We have been asked to find or calculate the surface area of the cylinder.
To calculate the surface area of the cylinder, we will use the formula below :-
[tex]\bigstar \:\:\:\boxed{\sf{\:\:Surface \: Area_{(Cylinder)} = 2\pi r^2 + 2\pi rh \:\:}}[/tex]
Substitute the given values into the above formula and solve for surface area:
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = 2\pi r^2 + 2\pi rh[/tex]
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(3.14)(6 \: in)^2 + (2)(3.14)(6 \: in)(10\:in) [/tex]
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(3.14)(36 \: in^2) + (2)(3.14)(60\:in^2) [/tex]
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = (2)(113.04 \: in^2) + (2)(188.4 \: in^2) [/tex]
[tex]\sf:\implies Surface \: Area_{(Cylinder)} = 226.08 \: in^2 + 376.8 \: in^2 [/tex]
[tex]\sf:\implies \bf{Surface \: Area_{(Cylinder)} = 602.88 \: in^2}[/tex]
Therefore :-
The surface area of the cylinder is 602.88 in².[tex]\\[/tex]
