3х + 2y = 4
5x -y=-15
First answer: -2
Second answer: 5
Answer:
(-2,5)
x= -2
y=5
Step-by-step explanation:
I'm going to solve this through substitution
We need a variable by itself (and we also need it to be positive)
We solve for y in the second equation
5x-y= -15
5x+15=y
We can then plug this in for y into the first equation
3x+2(5x+15)=4
and solve for x
3x+10x+30=4
13x= -26
x= -2
We can then plug this value in for x into any of the two beginning equations and solve for y
5(-2)-y= -15
-10-y= -15
-y= -5
y =5

(−8)(0.09)(−125)
A.
(−8)(0.09)(−125) = (−8)(−125)(0.09)
= (1,000)(0.09)
= 90
B.
(−8)(0.09)(−125) = (−8)(−125)(0.09)
= (−1,000)(0.09)
= −90
C.
(−8)(0.09)(−125) = (−8)(−125)(−8)(0.09)
= (1,000)(−0.72)
= −720
D.
(−8)(0.09)(−125) = (−8)(−125)(−8)(0.09)
= (−1,000)(−0.72)

Given g(x) = 3x + 14 , find x if g(x) = 20
Answer: x = 2
Step-by-step explanation: If g(x) = 3x + 14, and g(x) = 20 also, you first can set 3x+14 = 20. To find the value of x, you want to isolate the variable. You can subtract 14 from both sides to get 3x = 6. Finally, to find out the value of x, divide 3 from both sides. This leaves you with x = 2. You can check this by plugging two back into the original equation 3 times 2 = 6, and 6 plus 14 equals 20.

Julie takes her kids to a playground that has the shape shown. A. While her kids are playing, Julie wants to get some exercise. If she does 2 laps around the playground, how much distance has she covered? B. The park service is creating a flyer for the playground and wants to list the area that the playground covers. How much area does the playground cover?
Answer:
a.) Total distance Julie cover = 128 feet
b.) Total area , the playground cover = 256 ft²
Step-by-step explanation:
P. S : The exact question is -
As given,
Length of 1 side = 16 feet
As , we have
4 sides of same length
⇒ Total length of playground = 16 + 16 + 16 + 16 = 16(4) = 64 feet
a.)
As given Julie does 2 lap of the playground
⇒ Total distance Julie cover = 64 + 64 = 128 feet
b.)
As the playground has equal side, so it must be of square shape
And, we know
Area of square = (Length of one side)²
= ( 16 )² = 256 ft²
∴ we get
Total area , the playground cover = 256 ft²

what is half of 3/4 teaspoon?
Answer:
One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons. One method of finding the answer in the fraction form of 3/8 is to multiply the fraction 1/2 by 3/4 : )
Step-by-step explanation:
One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons.
Here, we have,
given that,
what is half of 3/4 teaspoon
One method of finding the answer in the fraction form of 3/8 is
to multiply the fraction 1/2 by 3/4 ,
or, we can divide 3/4 by 2
i.e. 1/2 × 3/4
as, half = 1/2
so, we get,
=> 3/ 2×4
=> 3/8
=>0.375
Hence, One half of 3/4 teaspoon is equal to 3/8 or 0.375 teaspoons.

The area of any prism is base*height.
The main trick in this problem is determining which face is the base, since this is a triangular prism. We need to calculate the area of the triangle base.
11*8/2=44
Now we just need to multiply by the height.(note height is b this case because the prism is actually printed with the base facing towards you.
44*5=220
Done!
So answer choice B 220.
Answer:
220 is the right answer

Answer:
DIMENSIONS:
THE DOUBLE: 42.6 m cubed on both the length, width, and height
THE HALF: 10.6 m cubed on both the length width and height
THE CUBE: 21.3 m cubedon both the lengrh, width, and height
MOST HEIGHT: The Double at 42.6 m cubed
Step-by-step explanation:
We know that we have 64 m cubed. First, we should find out the volume of each cube. 64 times 2 is 128. This means the Double equals 128 in volume and half of 64 is 32. this means the Half is 32 in volume. Since these are all cubes, every side is exactly the same(or else it would be a rectangle) the formula for finding volume is length times width times height, we would divide EACH of the volumes by 3. 128 divided by 3 is 42.6 meaning the doubles dimensions would be 42.6 on each part of the cube (the lenght width and height would all be 42.6) you can check this by multiplying 42.6 by 3 which takes us back to 128. For the cube we would do 64 divided by 3 which is 21.3 pn every side and 32 divided by 3 is 10.6. The one with the most height is the double. I am not sure how to find the floor space I am super sorry but I hope this helps :)
