sove for x: -3x+2z=5
Answer:
x = -(5-2z)/3
Step-by-step explanation:
-3x+2z=5
Subtract 2z from each side
-3x+2z-2z=5-2z
-3x = 5-2z
Divide each side by -3
-3x/-3 = (5-2z)/-3
x = (5-2z)/-3
Answer:
x = 2 / 3z - 1 and 2 / 3
Step-by-step explanation:
Consider the steps below;
[tex]- 3x + 2z = 5 - Subtract 2z From Either Side of Equation,\\- 3x = 5 - 2z - Take - 3 Divided on Either Side,\\\\x = ( - 5 / 3 ) + 2 / 3z - ( Simplify ),\\x = - 1 \frac{ 2 }{ 3 } + 2 / 3z - Re - arrange,\\x = \frac{ 2 }{ 3 } z - 1 \frac{ 2 }{ 3 } \\\\Conclusion ; ( x = \frac{ 2 }{ 3 } z - 1 \frac{ 2 }{ 3 } )[/tex]
Solution ; x = 2 / 3z - 1 and 2 / 3

There is only one group with 2 numbers out of 4 who watched TV last night.
A prize bag contains four country music CDs, eight pop music CDs, and five classic rock CDs. What is the probability of pulling out a classic rock CD and then, without replacing it, pulling out a country music CD? Express your answer in decimal form, rounded to the nearest hundredth.
Answer:
It is actually 0.07 on edge
Step-by-step explanation:
Got it right
The probability of pulling a classic rock CD is 0.71 and then without replacement probability of pulling Country side CD is 4.
What is Probability?Probability is the chance that something will happen, or how likely it is that an event will occur.
Formula for the calculation of probabilityProbability of an event to happen = [tex]\frac{number of favorable outcomes }{total number of outcomes}[/tex]
According to the given question
we have
a bag which contains ,
country music CDs = 4
pop music CDs = 8
classic rock CDs = 5
total number of CDs = 4+8+5 =17
probability of pulling a classic rock CD = [tex]\frac{5}{17}[/tex] =0.71
without replacing
total number of CDs left = 17-1 =16
probability of pulling a country music CD =[tex]\frac{4}{16}[/tex]=4
Hence, the probability of pulling a "classic rock CD" is 0.71 and then without replacing probability of pulling "country music CD" is 4

Suppose the sphere below with radius r has a surface area equal to 50 units². find the surface area of the sphere with twice the radius.
Answer:
[tex]200$ unit^2[/tex]
Step-by-step explanation:
Surface Area of a Sphere[tex]=4\pi r^2[/tex]
Given that the surface area of a sphere is 50 units².
Then:
[tex]4\pi r^2 =50\\r^2=\dfrac{50}{4\pi}\\ r=\sqrt{\dfrac{50}{4\pi}}[/tex]
If a sphere has twice the radius of the sphere above
Its radius, [tex]r=2\sqrt{\dfrac{50}{4\pi}}[/tex]
Therefore its Surface Area

Q10 A student wants to raise £100 for charity.
He will sell hot dogs at a disco.
The Supermarket
He will make 150 hot dogs.
Hot dog sausages tin of 8 50p
Hot dog buns packet of 6 90p
He buys ingredients at The Supermarket
If he sells all the hot dogs, what is the minimum price he must charge to make a profit of £100?
Show all your working
Answer:
He must charge minimum £0.84 for one hot dog.
Step-by-step explanation:
Ingredients cost for hot dogs at the supermarket,
Price of dog sausages tin of 8 = 50p ≈ £0.5
Price of dog bun packs of 6 = 90p ≈ £0.90
Number of tins required for 150 hot dogs = [tex]\frac{150}{8}[/tex] = 6.25
So student will purchase 7 tins.
Cost of 7 tins = 7 × 0.5
= £3.5
Number of dog buns packets required = [tex]\frac{150}{6}[/tex] = 25
Cost of 25 packs = 25 × 0.9
= £22.5
Total cost of the material used for 150 buns = 22.5 + 3.5
= £26.0
Let the selling price of each hot dog = £x
Then selling price of 150 hot dogs = £150x
Students wants the profit = £100
So, Selling price - Cost price = profit
150x - 26 = 100
150x = 126
x = [tex]\frac{126}{150}[/tex]
x = £0.84
Therefore, he must charge minimum £0.84 for one hot dog.
Given the equation (x + 3) ^ 2 + y ^ 2 = 81 choose ALL correct answers
1.The center of the circle would lie on the x-axis.
2. The center of the circle would lie on the y-axis.
3.The center of the circle would lie in a quadrant.
4. The radius is 9
5. The radius is 40.5
6.The radius is 81
7. The diameter is 18
8.The diameter is 81
9. The diameter is 162 Help please
Answer:
The equation of a circle having the center (a, b) and radius r could be formulated by:
(x - a)^2 + (y - b)^2 = r^2
A circle, which has equation form: (x + 3) ^ 2 + y ^ 2 = 81, can be turned into:
(x - -3)^2 + (y - 0)^2 = 9^2
=> center (-3, 0)
=> radius = 9
=> Option 1 is correct
=> Option 4 is correct
=> Option 7 is correct
Hope this helps!

If a rectangle has a permeter of 72 yards and it’s width is 9 yards what is the length of the missing length
Answer:
27
Step-by-step explanation:
The perimeter is 2x + 2y
Say x = 9
18 + 2y = 72
2y = 54
y = 27
Answer:
The length would be 27 yards
Step-by-step explanation:
The perimeter formula is l+l+w+w.
Jacob's little brother thinks that he could design a better lion enclosure than the one he sees at the zoo. He makes a drawing of his new and improved enclosure where every inch represents 25 feet. In his drawing the length of the rectangle is 7 ¼ inches. What is the actual length of the lion enclosure? The diagonal of the rectangle in his drawing is 10 ½ inches. What is the width of the enclosure in feet? What is the area of the enclosure in square feet?
Answer:
Step-by-step explanation:
Length
1 inch = 25 feet
7 1/4 inches = x feet
1 * x = 25 * 7 1/4
x = 25 * 7.25
Length = 181.25 feet
The length is 181.25
hypotenuse length
The diagonal = 10 1/2 inches
The diagonal = 10.5 inches
hypotenuse = 10.5 * 25 = 262.5 feet
Width
L^2 + W^2 = Diagonal^2
181.25² + W² = 262.5²
32851.5625 + W² = 68906.25 Subtract 32851.5625 from both sides
W² = 68906.25 - 32851.5625
W^2 = 36054.6875 Take the square root of both sides
W = 189.88
Area
Area = L * W
Area = 181.25 * 189.88
Area = 34415.88 square feet.
