Is 68 prime or composite
Answer:
composite
Step-by-step explanation:
the number 68 is an even number, which means it is divisible by 2.
four cities lie along a straight highway in this order city a, city, city c, city d. The distance from city a to city b is 5 times the distance from city b to city c. The distance from city a to city d is 2 times the distance from city a to city d. the distance between city d and city c is 10 miles. What are the distances between the cities?
Dividing the segments and finding the lengths, it is found that the distance between the two cities is of 130 miles.
--------------------------------
We want to find the distance between cities a and d.Due to the cities along the highway, the distance is given by:[tex]ad = ab + bc + cd[/tex]
--------------------------------
The distance from city a to city b is 5 times the distance from city b to city c, and thus:[tex]ab = 5bc[/tex]
In terms of x, [tex]bc = x, ab = 5x[/tex]
--------------------------------
The distance from city b to city c is 2 times the distance from city c to city d, and thus:[tex]bc = 2cd[/tex]
In terms of x, [tex]cd = \frac{x}{2}[/tex]
--------------------------------
The distance between city d and city c is 10 miles, thus:[tex]\frac{x}{2} = 10[/tex]
[tex]x = 20[/tex]
--------------------------------
The other distances are:[tex]bc = x = 20[/tex]
[tex]ab = 5x = 5(20) = 100[/tex]
--------------------------------
The distance between cities a and d is:[tex]ad = ab + bc + cd = 100 + 20 + 10 = 130[/tex]
The distance between the two cities is of 130 miles.

Answer:
-10+6w+14v hope this is right if not sorry
Answer:
A. -14w + 14v
Step-by-step explanation:
Note that the formula for the perimeter of a rectangle is 2W + WL = P. We can substitute those variables with the equations we are given and simplify.
2(5v - 10w) + 2(2v + 3w)
~Use distributive property rules to simplify
10v - 20w + 4v + 6w
~Combine like terms

Answer:
Slope = ⅓ Y-intercept = -2
Step-by-step explanation:
by transforming the equation to y= ⅓x -2
then it becomes Y= ⅓x +(-2)
then you should get m= ⅓ and b = -2
Step-by-step explanation:
(a)
y = mx + b
y = (1/3)x + (-2)
y = 1/3x - 2
(b)
x - 3y = 6
x - 3(0) = 6
x - 0 = 6
x = 6

Job A: $8.95 per hour (40 hours a week)Job B: $16,400 per year
a. Which job pays more?
b. How much more?
Answer:
Job A pays pays better
Step-by-step explanation:
Job A pays more ($18,616) by $2,216 more
there are roughly 52 weeks in a year so multiply that by 40 to get the total hours worked in a year. = 2,080
2,080 hours worked per year multiplied by the hourly pay $8.95 = $18,616
Job A pays $18,616
Job B only pays $16,400
If U.S. $1 = 7.82 Hong Kong dollars, what is the value of 25 Hong Kong dollars in U.S. dollars?
Answer:
3.25
Step-by-step explanation:
1 hong kong dollar = 0.13 cents in us dollars
0.13x25=3.25
The value of 25 Hong Kong dollars in U.S dollar is $3.1969
Given that :
$1 = 7.82 Hong Kong dollars
Let the equivalent Number of U.S dollars = p
This means that :
$1 = 7.82 Hong Kong dollars
$1 = 7.82 Hong Kong dollars $p = 25
Cross multiply :
25 × 1 = 7.82 × p
25 = 7.82p
Divide both sides by 7.82
25 / 7.82 = p
p = $3.1969
Hence, 25 Hong Kong dollars is 3.1969 U.S dollars.

hi <3
multiply the coefficient of x^2 with the last value:
2 x 3 = 6
you need to find a value that multiplies to give 6 and adds to give 5
this would be 3 and 2
now you have:
(x + 3)(x + 2)
we need to incorporate the 2 into it
you can divide the 2 by 2 so that part is fine. however, as 3 cant be divided by 2, you have to carry the 2 up as a coefficient for x
your final answer works out to be:
(2x + 3)(x + 1)
hope this helps :)

~[tex]\huge\text{Amphitrite1040:)}[/tex]What kind of lines are the two opposite sides of a rectangle?
parallel lines
perpendicular lines
neither
Answer:
They're parallel lines .
Step-by-step explanation:
But they are perpendicular to the lines they meet with. i.e; width lines are parallel to each other. But width lines are perpendicular to length lines.
[tex]{ \sf{}}[/tex]
Answer:
Parallel lines
Step-by-step explanation:
It wouldn't be perpendicular lines because a perpendicular line is when two lines come together to make a perfect corner, or 90 degree angle. It wouldn't be neither because parallel lines is when they face each other and if they were to go on forever they would never touch because they go straight. That may sound confusing but and example would be like the opposite lines on a square, how they're perfectly straight and opposite each other. The answer is parallel lines. Hope this helps! Good luck.

Answer:
a = 45°, x = 90°
Step-by-step explanation:
2a + x + 2a + x = 360°
2a = x because they are the same two angles. 2 out of 4 angles = 1/2. 1/2 x 360° = 180°
2a + x = 180°
Since 2a = x, that means x has to equal to 90 and 2a has to also equal to 90
180°/2 = 90°
x = 90
2a = 90
2a/2 = 90/2
a = 45°
2(45) + 90 = 180°
90 + 90 = 180
180 = 180

Answer:
Step-by-step explanation:
To convert the measurements of metric system into another units of metric system we have to either multiply it by 10, 100, 1000, 10000, 100000, etc or divide by 10, 100, 1000, 10000, 100000, etc.
If we have to convert bigger unit into smaller unit then we have to multiply the unit by the multiples of 10, then the decimal point is shifted to right by 1 or 2 or 3 or 4 , etc. places.
For example, 1.2 kg is converted into g so we have to multiply it by 1000, so decimal point is shifted to right by 3 places, i.e.,
1.2 x 1000 = 1200 g
If we have to convert smaller unit into bigger unit then we have to divide the unit by the multiples of 10, then the decimal point is shifted to left by 1 or 2 or 3 or 4 , etc. places.
For example, 12 cm is converted into m so we have to divide it by 100, so decimal point is shifted to left by 2 places, i.e.,
12 / 100 = 0.12 m

Answer:
(0,-3)
(8,0)
Step-by-step explanation:
Putting x = 0
[tex]3(0) - 8y = 24[/tex]
[tex] - 8y = 24[/tex]
[tex]y = \dfrac{ - 24}{8} [/tex]
[tex]y = - 3[/tex]
x - intercept = (0.-3)
Putting y = 0
[tex]3x - 8(0) = 24[/tex]
[tex]3x = 24[/tex]
[tex]x = \dfrac{24}{3} [/tex]
[tex]x = 8[/tex]
y - intercept = (8,0)
Answer:
x-intercept is 8
y-intercept is -3
Step-by-step explanation:
We can put the equation into slope intercept form to find the y-intercept.
3x - 8y = 24
~Subtract 3x to both sides
-8y = 24 - 3x
~Divide -8 to everything
y = -3 + 3/8x
~Reorder
y = 3/8x - 3
In slope intercept form we know that m = slope and b = y-intercept in the formula [ y = mx + b ] so we know that the y-intercept will be -3. To find the x intercept we can substitute 0 for y and solve for x.
0 = 3/8x - 3
3 = 3/8x
x = 8
