Answer:
X=1, y=6
Step-by-step explanation:
Let's solve your system by substitution.
−8x−2y=−20;x+2y=13
Rewrite equations:
x+2y=13;−8x−2y=−20
Step: Solvex+2y=13for x:
x+2y=13
x+2y+−2y=13+−2y(Add -2y to both sides)
x=−2y+13
Step: Substitute−2y+13forxin−8x−2y=−20:
−8x−2y=−20
−8(−2y+13)−2y=−20
14y−104=−20(Simplify both sides of the equation)
14y−104+104=−20+104(Add 104 to both sides)
14y=84
14y
14
=
84
14
(Divide both sides by 14)
y=6
Step: Substitute6foryinx=−2y+13:
x=−2y+13
x=(−2)(6)+13
x=1(Simplify both sides of the equation)
Answer:
x=1 and y=6

If y varies inversely as the square of , and Y =4/63 when x=3 find y when x=5
Answer: 20/189
Step-by-step explanation: Y is proportional to x which states that 4/63 is proportional to 3 so when x=5 then it will be 5*4/63/3=20/63/3=20/63*1/3=20/189
Consider the equation x – 10 = 11 – 2x.

differences between larva of silkworm and larva of bee
Answer:
Answer: The larvae of a silk moth secrete the silk thread which is used to make clothes. Honey bees produce and store honey which is nutritious food. Silkworm is a creamy white colored insect which is about 2-3 cm long and shining in nature.
Bee larvae have been shown to be an excellent food source for rearing insects
Silk worm larvae is used in extracting silk and thus help in making clothes.
Bee larvae is used in pest control.
The silkworms feed solely on large amounts of leaves from the mulberry tree for around 30-40 days
The majority of honey bee larvae eat honey, but larvae that are chosen to become future queens will be fed with royal jelly.

Given: Segment AD is an altitude
Find: BC
Answer:
[tex]BC=71\text{ units}[/tex]
Step-by-step explanation:
Since AD is an altitude, we know that AD⊥BC by the definition of altitudes.
Then, this means that ∠ADC will be 90° by the definition of perpendicular lines. Therefore:
[tex]12x+6=90[/tex]
Solve for x. Subtract 6 from both sides and then divide by 12:
[tex]12x=84\\[/tex]
[tex]x=7[/tex]
Therefore, the value of x is 7.
BC is the addition of the segments BD and DC. In other words:
[tex]BC=BD+DC[/tex]
We already know the equations of BD and DC. Substitute:
[tex]BC=(5x-7)+(2x+29)[/tex]
Since we know that the value of x is 7, substitute 7 for x and evaluate for BC:
[tex]BC=(5(7)-7)+(2(7)+29))[/tex]
Evaluate:
[tex]BC=(35-7)+(14+29)[/tex]
Evaluate:
[tex]BC=28+43=71[/tex]
Therefore, the value of BC is 71 units.
Answer:
BC = 71
Step-by-step explanation:
12x + 6 = 90
x = 7
5x - 7 + 2x + 29 = 7x + 22
7(7) + 22 = 49 + 22
49 + 22 = 71
BC = 71
The radius of a circle is 3 m. Find its circumference in terms of pi.
The circumference of a circle is [tex]2\pi r[/tex]

It says to leave in terms of pi which means that we won't solve [tex]6\pi[/tex]
Thus the answer is [tex]6\pi[/tex].

Can someone explain to me why I have to make the + symbol a - when the question asks 7a-(3+8a)?
Step-by-step explanation:
Because there is a negative sign before parentheses.
The sign( a) is negative When multiplied by the negative before the parentheses The sign becomes negative
Hey there!
First, let's solve this maths problem:
7a-(3+8a)
Here we should use the Distributive Property and distribute -
Wait, what? Distribute a minus? Yeah! The minus sign (in this case) is the same as -1:
7a-3-8a
Now, why did the plus sign change to the minus sign?
Because a negative times a positive is a negative.
Hope everything is clear.

If chocolate chips have 20 calories in 2t how many calories in 3 cups
Answer:
Please Specify if the chocolate chips are measured in teaspoon or tablespoon?
Step-by-step explanation:
Assuming that the chocolate chips are measured in Teaspoons
given: 20 calories= 2 teaspoons
Now we can say that 48 teaspoons= 1 cup
therefore if 2 teaspoons make 20 calories , how many does 48 teaspoons make?
(48x20)/2 = 480 calories
we can now say that 48 teaspoons =1 cup = 480 calories
3x480=1440
so, 3 cups= 1440 calories

Back to my question. I have this problem that I cant solve.
-21-9k=-8(6k+3)
I need to get the answer k= -0.08
Can someone please help me and give me the explanation?
Here's how to solve your equation step by step:
−21−9k=−8(6k+3)
Step 1: Simplify both sides of the equation.
−21−9k=−8(6k+3)
−21+−9k=(−8)(6k)+(−8)(3) (Distribute)
−21+−9k=−48k+−24
−9k−21=−48k−24
Step 2: Add 48k to both sides.
−9k−21+48k=−48k−24+48k
39k−21=−24
Step 3: Add 21 to both sides.
39k−21+21=−24+21
39k=−3
Step 4: Divide both sides by 39.
39k/39 = -3/39
Here's the answer: -1/13 or -0.08.

Answer:

unsimplified = 2/8
Step-by-step explanation:
2/8 is your answer because
you can see here that there are 8 bars that are being covered by his total sales. That means that 8 is the denominator, then, the money is going 2 more bars than 225 dollars. So if we see, then we can find out that the sales are going up till 275, and the difference of 275 and 225 is 50. And each bar over here represents a difference of 25. That means that 2/8 (1/4) of the sales are more than $225.
So hence, your answer is 1/4

Answer:
1/4
Step-by-step explanation:
From inspection of the box plot:
Minimum value = 100Q1 = 150Q2 (median) = 200Q3 = 225Maximum value = 275The left whisker (min value) to Q1 represents the bottom 25% of the data
Q1 to Q2 represents the second 25% of the data
Q2 to Q3 represents the third 25% of the data
Q3 to the right whisker (max value) represents the top 25%
Therefore, the sales of over $225 represent the top 25% of the data.
25% represented as a fraction is 25/100 = 1/4
help por favor how do i Multiply. Enter the product in simplest form.
3/4 x 2/11 = 3/22
Step by step explanation
multiply both numerators together: 3 x 2 = 6
multiply both denominators together: 4 x 11 = 44
3 x 2 = 6 4 x 11 = 44 = 6/44
Divide 6 by 2 and 44 by 2.
6 / 2 = 3
44 / 2 =22
thus your answer is 3/22

An airplane is flying at a speed of 350 mph at an angle of 100 degrees. A wind is blowing at 50 mph at an angle of 40 degrees. Find the resulting speed and direction.
The resulting speed and direction of the airplane are approximately 377.492 miles per hour and 93.413°, respectively.
How to apply vectors to find absolute velocity of the airplane
In this question we must apply vectors in rectangular form to determine the absolute velocity of an airplane. which is the sum of velocity at still air ([tex]\vec v_{A/W}[/tex]) and wind velocity ([tex]\vec v_{W}[/tex]), both in miles per hour. If we know that [tex]v_{W} = 50\,\frac{mi}{h}[/tex], [tex]\theta_{W} = 40^{\circ}[/tex], [tex]v_{A/W} = 350\,\frac{mi}{h}[/tex] and [tex]\theta_{A/W} = 100^{\circ}[/tex], then resulting velocity is:
[tex]\vec v_{A} = 50\cdot (\cos 40^{\circ}, \sin 40^{\circ}) + 350\cdot (\cos 100^{\circ}, \sin 100^{\circ})[/tex]
[tex]\vec v_{A} = (-22.474, 376.822)[/tex]
Whose magnitude ([tex]v_{A}[/tex]), in miles per hour, and direction ([tex]\theta[/tex]), in degrees, are, respectively:
[tex]v_{A} = \sqrt{(-22.474)^{2}+376.822^{2}}[/tex]
[tex]v_{A} \approx 377.492\,\frac{mi}{h}[/tex]
[tex]\theta_{A} = \tan^{-1} \left(\frac{376.822}{-22.474} \right)[/tex]
[tex]\theta_{A} \approx 93.413^{\circ}[/tex]
The resulting speed and direction of the airplane are approximately 377.492 miles per hour and 93.413°, respectively. [tex]\blacksquare[/tex]
