First, add 10 to both sides.
2X - 10 + 10 = 30 + 10
2X = 40
Finally, we have to divide both sides by 2!
2X / 2 = 40 / 2
X = 20

Answer:
Option DStep-by-step explanation:
We just need to simplify the distributive property.
=> 8(5x - 3)=> (8 × 5x) + (8 × -3)=> (40x) + (-24)=> 40x - 24Hence, Option D is correct.
can someone please help me out asap? thank you
AnswerA,B,C
Step-by-step explanation:
A is right , using the exponet property, it turns into [tex]x^{1/5}[/tex] to the 7 power which equal x to the 1.4 th power. Using the product of power, [tex]x^{1/5}[/tex] to the 7th power is the same as 1/5 times 7 which equal 1.4. so b is right .Using the fractioal exponet rule C is also right as 5th root of x to the 7th power is the same as to the 7 power divided by 5 which 1.4 so c is right

If a six-sided die is rolled 5 times, what is the probability of rolling numbers less than 3 ?
Distributions of probabilities help to model our world, allowing us to estimate the likelihood of a said event or to approximate the variability of incidence. It is a common way of describing the probability of an event as well as possibly forecasting it, and the further calculation can be defined as follows:
The possibility of rolling a six on a 6-sided die is [tex]\frac{1}{6}[/tex]. There are
Three 6's are therefore [tex]\binom{1}{6}^3[/tex] likely to roll.
The probability that you don't roll a 6 is [tex]\binom{5}{6}[/tex] and you are not 6 double the record is[tex]\binom{5}{6}^2[/tex].
In 5 tests, there are 10 different ways [tex]\binom{5}{3}=10[/tex] to rolle three 6s.
Then we all have together:
[tex]\to 10 \times \binom{1}{6}^3 \times \binom{5}{6}^2 \approx 0.0322[/tex]
Therefore, the final answer is "0.0322".

An equation for the line whose slope is 5 and which passes through the point ( –2, 11)
The required equation of the line whose slope is 5 and passes through the point (-2, 11) is (y - 11) = 5(x+2) or y = 5x + 21.
An equation for the line whose slope is 5 and which passes through the point ( –2, 11) is to determined.
A line can be defined by the shortest distance between two points is called a line. The standard equation of the line is y =mx + c, where m and c are the slope and y-intercept of the line respectively.
Slope ( m ) = 5 and an ordered pair ( -2 , 11 ) is given in question
Equation of line is given as
[tex]y-y_1= m(x-x_1)\\[/tex]
y - 11 = 5 (x + 2)
y - 11 = 5x + 10
y = 5x + 10 +11
y = 5x + 21
Thus, the required equation of the line whose slope is 5 and passes through the point (-2, 11) is (y - 11) = 5(x+2) or y = 5x + 21.

Three books cost $18.75. How much would 8 books cost?
Answer:
$50
Step-by-step explanation:
Create a proportion where x is the cost of 8 books:
[tex]\frac{3}{18.75}[/tex] = [tex]\frac{8}{x}[/tex]
Cross multiply and solve for x:
3x = 150
x = 50
So, 8 books would cost $50
Answer: $50
Step-by-step explanation:
$18.75 divided by 3 = $6.25
$6.25 times 8 = $50

Answer:
x=8.5
Step-by-step explanation:
∠AOC=68
∠COD= (2x+5)
∠AOC and ∠COD are complimentary angles. This means that when you add them together you get 90.
∠AOC + ∠COD = 90
68 + (2x+5) =90
2x+5=22
2x=17
x=8.5

What is the area of the paper used to wrap a can of soup if the can is 11 cm tall and has a diameter of 7.5 cm. Show all formulas and work.
Notice that a can is a cylinder, which is basically two circles and one rectangle. Now, the question wants area of this rectangle.
You know the width of the rectangle (or the paper), which is 11cm. How do you find the length then?
Notice that the length of the rectangle is also the circumference of the circles. From here, use C = πd where C is circumference and d is diameter. The d is given, which is 7.5 cm. Depending on the question, π can be 3.14, 22/7 or the actual pi.
multiply π and 7.5cm and you get the circumference. Multiply this to 11cm and you get area of the rectangle.
The velocity v of an object rolled down an inclined plane is given by the formula v=39d where d is the distance the object has rolled solve the formula for d

A medical insurance company offers two prescription-drug insurance plans. With plan 1, James would pay the first $150 of his prescription costs and 50% of all costs after that. With plan 2, James would pay the first $280 of costs, but only 20% of the rest. For what amount of prescription costs will plan 2 save James money? (Assume that his prescription costs exceed $280.) mostly need help on how to do the problem
Answer:
when expenses are greater than $433.33
Step-by-step explanation:
set up equations for each plan
let 'x' = prescription costs
Plan 1: y = 150 + .5x
Plan 2: y = 280 + .2x
150 + .5x = 280 + .2x
.5x = 130 + .2x
.3x = 130
x = 433.33
i checked my answer by graphing each equation and $433.33 is the break-even point where each plan would have the same costs but, after that, the expenses for Plan B are less
