A bag contains 5 red marbles, 3 blue marbles, 7 yellow marbles, and 2 green marbles. Which ratio can be used to compare the red
marbles to the blue marbles?
A) 3/5
B) 3/8
C) 5/3
D) 5/8
Answer:
C) 5/3
Step-by-step explanation:
The ratio comparing red to blue marbles can be created by putting 5 and 3 together, since there are 5 red marbles and 3 blue marbles
This gets you 5/3
So, the correct answer is C) 5/3
Answer:
5/3
Step-by-step explanation:
This is because there are 5 red marbles and there are 3 blue marbles. If you put them side by side, the ratio is 5:3 or 5/3.
Dilate Point B by a scale factor of 3:
(12,12)
(12,0)
(0,12)
(4,3)
We can write the coordinates of the vertices of the triangle after dilation by a scale factor as -
C'(9, 6)
B'(0, 12)
A'(12, 12)
What is dilation?Dilation is the enlargement or shrinking of the coordinates.
Given is a triangle as shown in the image.
The coordinates of the vertices of the triangle are -
C(3, 2)
B(0, 4)
A(4, 4)
For the dilation by a scale factor of {K} = 3, we can write -
C'(3 x 3, 2 x 3) = C'(9, 6)
B'(0 x 3, 4 x 3) = B'(0, 12)
A'(4 x 3, 4 x 3) = A'(12, 12)
Therefore, we can write the coordinates of the vertices of the triangle after dilation by a scale factor as -
C'(9, 6)
B'(0, 12)
A'(12, 12)

Solve the system of equations - 8x - 5y = -13 and - 4x – 5y = 11 by
combining the equations.
Answer:
(6,-7)
Step-by-step explanation:
subtract them:
-8x - 5y = -13
-4x - 5y = 11
you get
-4x = -24
so x = 6
plug x into the second equation:
-24 - 5y = 11
-5y = 35
y = -7
so your solution is (6,-7).
Answer:
Your solution is (6, -7).
Step-by-step explanation:
Combining the equations is also known as substitution. This is done when you substitute one variable into another equation.
-8x - 5y = -13
-4x - 5y = 11
Let's change the second equation into one with one variable on each side.
-5y = 4x + 11
y = -4/5x - 11/5
Now, plug this into your first equation.
-8x - 5(-4/5x - 11/5) = -13
Distribute the -5 sign.
-8x + 4x + 11 = -13
Combine the like terms.
-4x + 11 = -13
-4x = -24
Isolate x by dividing both sides by -4.
x = -24/-4
x = 6
Now plug this back into either equation.
y = -4/5(6) - 11/5
Multiply.
y = -24/5 - 11/5
Subtract.
y = -35/5
Simplify.
y = -7
Your solution is (6, -7).
Check this by plugging in these values into the equation you have not checked yet.
-8(6) - 5(-7) = -13
-48 + 35 = -13
-13 = -13
Your solution is correct.
Hope this helps!

Answer:
-13,-7,-3,0,3
-9,-4,-6,3,8
Step-by-step explanation:
Answer:
A) -13, -7, -3, 0, 3 B) -100, -99, -8, -25/3, -2
Step-by-step explanation:
3)Ordered from least to greatest is: -13, -7, -3, 0, 3
(The higher the negative the "smaller" it is)
4) -100, -99, -8, -25/3, -2
These numbers are listed in order from least to greatest with the error being -25/3. This equals -8.333 and should be in front of the -8 because it is a lesser value. The correct order would be: -100, -99, -25/3, -8, -2 but your answer asks for one error so use the numbers above.

Fiber one bran cereal boasts that it contains 57% of the Daily Value of fiber you need. If 1 serving contains 15 gram of fiber, how much fiber do you need in one day
Answer:
26.3 grams
Step-by-step explanation:
57% of fiber is 15 grams. To find 1% you would divide 15 by 57 which is 0.2631578947. Now multiply 1% by 100 to get 100% fiber. The amount of fiber needed per day is 26.31578947 (the rounded answer is 26.3)

The expressions which is equal to 10⁵ are 10³. 10² and 10 . 10 . 10 . 10 . 10.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
The given expression is 10⁵.
(10⁴)¹ = 10⁴
We have a rule of exponents,
xᵃ . xᵇ = xᵃ⁺ᵇ
10³. 10² = 10³ ⁺ ² = 10⁵
1 / 10⁵ = 10⁻⁵
(10³)² = 10^(3 × 2) = 10⁶
10 . 10 . 10 . 10 . 10 = 10⁵
Hence the equivalent expressions are 10³. 10² and 10 . 10 . 10 . 10 . 10.
