Answer:
x=5
Step-by-step explanation:
10 +3x = 5x
Subtract 3x from each side
10+3x-3x= 5x-3x
10 =2x
Divide each side by 2
10/2 = 2x/2
5 =x

A locker combination has three nonzero digits, and the digits cannot be repeated. The first two digits are 1 and 2. What is the probability that the third digit is 3?
Answer:
Approximately 14% or 1/7
Step-by-step explanation:
To solve this problem, first find the ratio of 3 to the possible numbers.
There are 9 possible digits in one space on a non-zero combination lock. However, digits cannot be repeated, and 1 and 2 are already taken. Therefore, there are 7 possible digits (9 - 2 = 7). Therefore, the ratio of getting a 3 to possible digits is 1:7, as there is 1 '3' and 7 others.
As a fraction, 1:7 is 1/7. As a percentage, 1/7 is about 14%. Therefore, there is approximately a 14% chance that the third digit will be 3.

Use a calculator to find angle theta for which tan theta = 2. Round to the nearest hundredth.
Answer:
in degrees: theta = 63.43°
in radians: theta = 1.11 rad
Step-by-step explanation:
To find the value of the angle theta that gives us tan(theta) = 2, we should use the inverse function of the tangent in the calculator, that is, the arc tangent function.
Then, if we use the arc tangent function (in some calculators, it may be shown as 'atan' or 'tan^-1') in the value 2, we would find:
atan(2) = 63.435°
So the angle theta that gives us tan(theta) = 2 is theta = 63.43°.
Be sure to check in the calculator if the answer is given in degrees or radians.
In radians, we would find theta = 1.1071 rad (rounded to nearest hundredth: theta = 1.11 rad)
Round the number 5,370,288 to the nearest 100,000
Answer: 5,400,000
Step-by-step explanation:
Since the number in the ten-thousandths place is a seven, you will round up. Disregard any numbers before the ten thousandths place, and round up.
5,400,000 is the final answer.
Step-by-step explanation:
5,370,288
^
That is the thousands place.
Since 7 is higher then 5 then 3 would turn to 4
5,400,000 is the answer.

What is the slope of the line? y+3= -4(9x+7)
Answer:
-36
Step-by-step explanation:
y=-36x-25
y=mx+b
m=-36
m=slope
Hello there! :)
y+3=-4(9x+7)
This equation is written in point-slope form (y-y1=m(x-x1)
Where m is the slope.
In this case, it's -4.

write an equation and solve round to the nearest hundredth where necessary. 21 is 35% of what number
Answer:
21 is 35% of 60.
35% * x = 21
Multiply both side by 100 and divide both sides by 35.
x = 21 * 100/35
21 * 100 = 2100
2100/35 = 60.

What is the equation of the line in the slope intercept form
Answer:
Equation of line; y = - 6x
Step-by-step explanation:
As we can see from this graph, point ( 0, 0 ) lying on this graph intersects the y - axis such that it forms a y - intercept of 0;
At the same time we can note that the change in y / change in x, in other words the slope, differs by a rise of 6 / run of - 1, 6 / - 1 being a slope of - 6;
If this equation is in slope - intercept form ⇒
y = a * x + b, where a ⇒ slope, and b ⇒ y - intercept,
Equation of line; y = - 6x
Answer:
y = -6x
Step-by-step explanation:
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
the y intercept is 0 since it crosses the y axis at 0
To find the slope we need to points (0,0) and (10,-60)
m = (y2-y1)/(x2-x1)
= (-60-0)/(10-0)
= -60/10
= -6
The equation for the line is
y = -6x +0
y = -6x
How many ways can we award a 1st, 2nd and 3rd place prize among eight contestants?
56 ways
none of these
40320 ways
336 ways
Answer:
Total number of ways are 336.
Step-by-step explanation:
It is required to find the number of ways in which we can award a 1st, 2nd and 3rd place prize among eight contestants. It means we need to find the number of permutations. We need to find [tex]^8P_3[/tex].
Here, r = 3
So,
[tex]^nP_r=\dfrac{n!}{(n-r)!}\\\\^8P_3=\dfrac{8!}{(8-3)!}\\\\^8P_3=\dfrac{8!}{5!}\\\\^8P_3=\dfrac{8\times 7\times 6\times 5!}{5!}\\\\^8P_3=336[/tex]
So, there are 336 ways.
suppose a 3-digit number is to be formed using the digits 1,2,3,4,5. How many different numbers can be formed. (digits can be repeated)
Answer:
125
Step-by-step explanation:
For the first digit of our number, we have 5 options (1, 2, 3, 4, 5). For the second and third digits, we still have 5 options because the digits can be repeated. This means that the total different numbers we can make is 5 * 5 * 5 = 125 numbers. Hope this helps!
