The sum of two numbers is 70, and their difference 30. Find the two numbers using the process of substitution. Let the first umber = x and the second number = y.
Answer:
x = 50, y = 20.
Step-by-step explanation:
x + y = 70
x - y = 30
From the second equation x = 30 + y, so substituting this in the first equation:
30 + y + y = 70
2y = 70 - 30 = 40
y = 20
and x - 20 = 30
so x = 50.
Answer:
20 , 50
Step-by-step explanation:
The sum of two numbers is 70 ⇒ x + y = 70 -------------(I)
x = 70 - y
Their difference 30 ⇒ x - y = 30 ----------(II)
Substitute x = 70 - y in equation (II)
70 - y - y = 30
Combine like terms
70 - 2y = 30
-2y = 30 - 70
-2y = -40
Divide both sides by (-2)
y = -40/-2
x = 20
Substitute the value of x in (I)
20 + y = 70
y = 70 - 20
y = 50

You want to find how much it cost for 1kg of potatoes, which in this case is .45 cents. After that you want to multiply the price of 1kg by 50, to get your cost for 50 kg of potatoes, which would be $22.50 I hope this helps! :)
Answer:
$22.50
Step-by-step explanation:
If one. again is 10k and it costs 4.50, then you would do 4.50 multiplied by 5 because each 10k is 4.50 and thier is 50 in total so 5 bags of 4.50 meaning 4.5x5 which would get you $22.50

What is the equation of a line that passes through the point (8, -2) and is parallel to the line whose equation is 3x + 4y = 15?
Answer:
y = -3/4x + 4 or 3x + 4y = 16
Step-by-step explanation:
Step 1
Find the slope of the given line
we have
3x + 4y = 15
Isolate the variable y
Subtract 3x from both sides
3x + 4y -3x = 15-3x
Divide by 4 both sides
y = -3/4x + 15/4
the slope of the given line is
m = -3/4
Step 2
Find the equation of the line that passes through the point and is parallel to the given line
we know that
if two lines are parallel, then their slopes are equal
The equation of the line into point-slope form is equal to
y - y₁ = m(x-x₁)
we have
m= -3/4
(x1,y1) = (8,-2)
substitute in the equation
y + 2= -3/4(x-8)
y = -3/4x + 6 - 2
y = -3/4x + 4 or 3x + 4y = 16
therefore
the answer is
y = -3/4x + 4
or
3x + 4y = 16
find the postive value of x when y = 25

1 second/24 frames
so if he started with 0 frames
time s = (1/24) (additional f)
but he already had at least 250 frames
so
time s = (1/24)( f-250) or maybe less time if he had more than 250
24 s </= f - 250
or
f >/= 24 s + 250

12 lightbulbs are tested to see if they last as long as a manufacturer claims they do three lightbulbs failed a test two light bulbs are selected at random without replacement find the probability that both light bulbs failed the test
Using the hypergeometric distribution, it is found that there is a 0.0455 = 4.55% probability that both light bulbs failed the test.
The bulbs are chosen without replacement, and this is why the hypergeometric distribution is used to find the probability.
Hypergeometric distribution:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes. N is the size of the population. n is the size of the sample. k is the total number of desired outcomes.In this problem:
12 bulbs, thus [tex]N = 12[/tex]3 failed the test, thus [tex]k = 3[/tex].2 are selected, thus [tex]n = 2[/tex].The probability that both failed the test is P(X = 2), thus:
[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]
[tex]P(X = 2) = h(2,12,2,3) = \frac{C_{3,2}C_{9,0}}{C_{12,2}} = 0.0455[/tex]
0.0455 = 4.55% probability that both light bulbs failed the test.

(b) 21 is 35% of what?
Answer:
a) 68
b)60
Step-by-step explanation:
a) 85% = 0.85
0.85 * 80 = 68
b) let x be the unknown number.
35% = 0.35
0.35x = 21
x = 60
Answer:
Step-by-step explanation:
a, 85% of 80
85% of 80
= 85/100*80
=85/100*80
