Answer: the answer is 21/32 and it is equivalent to 0.65625.
Step-by-step explanation:
50 units needed 12 units per case
Answer:
5 cases
Step-by-step explanation:
Since 12 does not go into 50, you need to buy a whole extra case.
12*4= 48, which is not enough for 50 units
5.1 km/h to mph. Round to the appropriate number of significant digits.
Step-by-step explanation:
Given-
5.1 km/hr
Relation bween mph and km :-
[tex]1 \: mph = 1.609 \: km[/tex]
So,
[tex] \frac{5.1 \: km}{1 \: h} \times \frac{1 \: km}{1.609} = 3.17 \: mph[/tex]
Therefore, the answer is 3.17 mph.
In a hand of cards, the ratio of black cards to red cards was 5 to 3. If the hand contained 15
black cards, which of the following proportions could be solved to find the number of red
cards?
Answer:
5:3 = 15:x
the answer would be 15 black cards to 9 red cards

Write an equation of the line that passes through the point (3,3) and is parallel to the line y= -1/2 + 3
Step-by-step explanation:
the slope = -½
the equation :
y-3 = -½(x-3)
y-3 = -½x + 3/2
y = -½x + 3/2 +3
y = -½x + 9/2

Step-by-step explanation:
Which statement explains why 13x−13y=−26 shares a solution with this system of equations:
10x−3y=29
−3x+10y=55
The given equation is derivable from the system of equations.
Response:
The reason why 13·x - 13·y shares a solution with the given system of equation is because -13·x - 13·y equals 55. I can subtract -3·x + 10 from the left side of 10·x - 3·y = 29, and subtract 55 from its right side. Subtracting equivalent expressions from each side of an equation does not change the solution of the equation.Method by which the relationship between the equations was determinedGiven:
The system of equation is presented as follows;
[tex]\begin{cases} \mathbf{10 \cdot x - 3 \cdot y} = 29...(1) & \text{ } \\ \mathbf{-3 \cdot x + 10 \cdot y} = 55...(2) & \text{ } \end{cases}\\[/tex]
Therefore, by subtracting equation (2) from equation (1), we have;
(10·x - 3·y) - (-3·x + 10·y) = 29 - 55 by subtracting equivalent expressions
13·x - 13·y = 29 - 55 = -26
13·x - 13·y = -26, which is the given equation
Given that the operation performed on equation (1) and (2) is the
subtraction of equivalent expressions, we have, that the solution for the
given equation, 13·x - 13·y = -26 is the same as the solution for given
system of equations.
The reason why 13·x - 13·y = -26 shares a solution with the system of equations based from the given options in a similar question is therefore;
D. because -3·x + 10·y is equal to 55, I can subtract -3·x + 10·y from the left side of 10·x - 3·y = 29 and subtract 55 from its right side. Subtracting equivalent expressions from each side of an equation does not change the solution to the equationLearn more about simultaneous equations here:

What is the sum of 3/7 + 1/3
Answer:
16/21
Step-by-step explanation:

(c) factoring and the zero-product principle
Step-by-step explanation:
Factoring is always an efficient method of solving a quadratic, if it has nice integer factors that can be easily identified. Here, the two prime factors of 35 have a sum of 12, so the factored form is easily found to be ...
(x +5)(x +7) = 0
This basically shows you the solutions are x=-5 and x=-7 "by inspection" in one step.
By contrast, the quadratic formula has 4 multiplications, a division, a square root, and 3 additions. That's a significant amount of arithmetic to get to the answers.
Factoring is the most efficient way to solve this quadratic.
Jackson bought an ultra-slim Television. The screen measures 13 cm in length and 12 cm in width. Television screen sizes are decided by the length of the diagonal. What is size of this screen? Round your answer to the nearest whole number.
Answer:
18 cm
Step-by-step explanation:
You can find the length of the diagonal by using the Pythagorean theorem.
a^2 + b^2 = c^2
12^2 + b^2 = c^2
144 + 169 = c^2
c^2 = 313
c = √313
c = 17.6918...
