Answer:
k= -58/9
Step-by-step explanation:
−17=5+9(k+4)
Simplify both sides of the equation.
−17=5+9(k+4)
−17=5+(9)(k)+(9)(4)(Distribute)
−17=5+9k+36
−17=(9k)+(5+36)(Combine Like Terms)
−17=9k+41
Flip it^
9k+41=−17
Subtract 41 from both sides
9k+41−41=−17−41
9k=−58
Divide both sides by 9
9k/9=−58 /9
k= -58/9
Hope it's right!
Answer:
k = -6 4/9
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
k = − 58 /9
Decimal Form:
k = − 6. 4
Mixed Number Form:
k = -6 4/9
Dylan walked 1/2 miles in 20 minutes. How far will he go (in miles) in 120 minutes?
Answer:
He will have gone 3 miles after 120 minutes
Step-by-step explanation: 120/20=6 1/2 times 6 is 3.
Answer:
3 miles
Step-by-step explanation:
Divide 20 by 1/2, which would be 40. Then divide 40 by 120, and that would lead to your answer, which is 3 miles.

Sergio and Allen ate lunch together in the school cafeteria. Each boy ordered a cheeseburger with fries. Sergio only ate 1/7 of his cheeseburger, while Allen ate 3/7 of his cheeseburger. How much cheeseburger did they eat together?
Answer:
4/7
Step-by-step explanation:
The word together symbolizes that we are adding.
We add the numerators but keep the denominator the same since it is already the same.
1+3 is 4, so that is our new numerator.

y is directly proportional to x. When y = 24, ,x=8. Work out the value of y when x=2
Answer:
When x = 2, y = 6
Step-by-step explanation:
Constant of Proportionality: y = kx
(24) = k(8)
24 = 8k
k = 3
y = kx ===> y = 3x
When x = 2:
y = 3x
y = 3(2)
y = 6

Seven less than 4 times the square of a number is 18. Find the two numbers.
The two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2
Let the unknown number be "x"
The square of an unknown number is expressed as x²4 times the square of a number is 4x²Seven less than 4 times the square of a number is 4x² - 7If the resulting expression is 18, this will be expressed as 4x² - 7 = 18
Solving the resulting expression
[tex]4x^2-7=18\\4x^2= 18+7\\4x^2=25\\x^2=\frac{25}{4}\\x=\pm \frac{5}{2}[/tex]
Hence the two numbers of seven less than 4 times the square of a number is 18 are -5/2 and 5/2

Expression A Expression B Expression C (−5)(−0.4)(1.8) (-45)(-19)(-112) −1(5+17) Expression D Expression E Expression F (−5)(−0.4)(1.8)(−3.25) (-49)(-34)(-12)(-12) −1(3.5−7) How many expressions will have a product that is positive?
Answer:
Expressions A, E, and F
Step-by-step explanation:
In general, when negative integers are multiplied; if the negative integers are even, then the product would be positive. But if the negative integers are odd, then the product would be negative.
Thus,
A. (−5)(−0.4)(1.8) = (2.0)(1.8)
= 3.6
B. (-45)(-19)(-112) = (855)(-112)
= -95760
C. −1(5+17) = -1(22)
= -22
D. (−5)(−0.4)(1.8)(−3.25) = (2.0)(-5.85)
= -11.7
E. (-49)(-34)(-12)(-12) = (1666)(144)
= 239904
F. −1(3.5−7) = -1(-3.5)
= 3.5
Thus expressions A, E and F have positive products.

The Pythagorean theorem states that the sum of the squares of the legs of a right triangle is equal to the square of the
hypotenuse by the formula a? + b2 = -2
If a is a rational number and b is a rational number, why could c be an irrational number?
Answer:
For the value of hypotenuse can be irrational, sum of squares of other two legs might be imperfect square number.
Step-by-step explanation:
We all know, the Pythagorean theorem can be stated as follows:
The sum of squares of two legs of a right angled triangle is equal to the square of the hypotenuse.
i.e.
[tex]a^2+b^2=c^2[/tex]
Where, [tex]c[/tex] is the hypotenuse and [tex]a, b[/tex] are the two other legs of the right angled triangle.
Given that:
[tex]a[/tex] and [tex]b[/tex] are rational numbers.
To find:
Situation for which [tex]c[/tex] is irrational.
Square of a rational number is always rational.
So, [tex]a^{2} , b^{2}[/tex] both will be rational.
And sum of squares of two rational numbers will also be rational.
Therefore, [tex]a^2+b^2[/tex] will also be rational.
and
[tex]c = \sqrt{a^2+b^2}[/tex]
For the value of [tex]c[/tex] can be irrational, sum of squares of other two legs might be imperfect square number.
A bag contains 10 red, 3 blue, and 2 yellow marbles. If 3 marbles are selected one at a time with replacement, find the probability that all three are different colors
Answer:
4/225
Step-by-step explanation:
To get 3 marbles that all three are different colors, we need to get a red, blue, and yellow marble (not necessarily in that order)
So we get the probability of getting each with replacement (meaning they are all out of 15) and multiply them.
The probability of getting a red is:
10/15 = 2/3
The probability of getting a blue is:
3/15 = 1/5
The probability of getting a yellow is:
2/15
So to get all 3 different colors:
2/3 * 1/5 * 2/15 = 4/225
