Answer:
x ( > or = ) 5/9
Step-by-step explanation:
● 2(1 + x) ( > or = ) 11 - 3x
● 2 + 2x ( > or = ) 11 - 3x
Add 3x to both sides
● 2 + 2x + 3x ( > or = ) 11 - 3x + 3x
● 2 + 5x (> or = ) 11
Substract 2 from both sides
● 2 + 5x -2 ( > or = ) 11 -2
● 5x (> or =) 9
Divide both sides by 5
● 5x/5 ( > or = ) 5/9
● x ( > or = ) 5/9

Answer:
Commutative property of multiplication
Step-by-step explanation:
This property states that numbers can be switched around when multiplying and the answer still remains the same
Answer:
C
Step-by-step explanation:
So we have the expression:
[tex]63\cdot 3[/tex]
And Jared rewrote it as:
[tex]3\cdot 63[/tex]
In other words, he just switched the order and the expression remains equivalent.
This is an example of the commutative property of multiplication, which states that if you change the order of a multiplication sentence, the sentence will remain equivalent.
So, our answer is C.
And we're done!

Step-by-step explanation:
10. Three kinds of teas are worth $4.60 per pound, $5.75 per pound, and $6.50 per pound. They are to be
mixed together to get 20 pounds of tea worth $5.25 per pound. The amount of $4.60 tea used is to be equal
to the amount of the other two teas combined. How many pounds of each tea should be used?
Answer:
The mass of the $4.60/lb tea that should be used in the mixture is 10 lb
The mass of the $5.75/lb tea that should be used in the mixture is 8 lb
The mass of the $6.50/lb tea that should be used in the mixture is 2 lb
Step-by-step explanation:
The parameters of the question are;
The worth of the three teas are
Tea A = $4.60/lb
Tea B = $5.75/lb
Tea C = $6.50/lb
The mass of the mixture of the three teas = 20 lb
The worth of the mixture of the three teas = $5.25 per pound = $5.25/lb
The amount of the $4.60 in the mixture = The sum of the amount of the other two teas
Therefore, given that the mass of the mixture = 20 lb, we have in the mixture;
The mass of tea A + The mass of Tea B + The mass of Tea C = 20 lb
The mass of tea A = The mass of Tea B + The mass of Tea C
Therefore;
The mass of tea A + The mass of tea A = 20 lb
2 × The mass of tea A in the mixture = 20 lb
The mass of tea A in the mixture = 20 lb/2 = 10 lb
The mass of tea A in the mixture = 10 lb
The mass of Tea B + The mass of Tea C = The mass of tea A = 10 lb
The mass of Tea B + The mass of Tea C = 10 lb
The mass of Tea B = 10 lb - The mass of Tea C
Where the mass of Tea C in the mixture = x, we have;
The mass of Tea B in the mixture = 10 lb - x
The cost of the 10 lb of tea A = 10 × $4.60 = $46.0
The worth of the tea mixture = 20 × $5.25 = $105
The worth of the remaining 10 lb of the mixture comprising of tea A and tea B is given as follows;
The worth of Tea B + The worth of Tea C in the mixture = $105.00 - $46.00 = $59.00
Therefore, we have;
x lb × $6.50/lb + (10 - x) lb × $5.75/lb = $59.00
x × $6.50 - x × $5.75 + $57.50 = $59.00
x × $0.75 = $59.00 - $57.50 = $1.50
x = $1.50/$0.75 = 2 lb
∴ The mass of Tea C in the mixture = 2 lb
The mass of Tea B in the mixture = 10 lb - x = 10 lb - 2 lb = 8 lb
The mass of Tea B in the mixture = 8 lb
Therefore, since we have;
Tea A = $4.60/lb
Tea B = $5.75/lb
Tea C = $6.50/lb
The mass of tea A in the mixture = 10 lb
The mass of tea B in the mixture = 8 lb
The mass of tea C in the mixture = 2 lb, we find;
The mass of the $4.60/lb tea that should be used in the mixture = 10 lb
The mass of the $5.75/lb tea that should be used in the mixture = 8 lb
The mass of the $6.50/lb tea that should be used in the mixture = 2 lb.

Step-by-step explanation:
x/4 + y/5 = 2 and x/2 + y = - 3. Solve for x and y
Answer:
A) x/4 + y/5 = 2
B) x/2 + y = - 3
Step-by-step explanation:
We multiply A) by -4 and B) by 2
A) -x - 4/5 y = -8
B) x + 2y = -6 then add A) and B)
1.2y = -14
y = 11 (2/3) = -11.6666666...
x + 2y = -6
x = -6 -2*-11.6666666
x = -23.3333332
h(n)=4n+ 4 find h (-3)
Step-by-step explanation:
h(n)=4n+ 4 find h (-3)
h(-3)=4(-3)+4
=-12+4
=--8
Answer: -8
Step-by-step explanation: h(n) = 4n + 4 means that
if we put an n into our function, a 4n + 4 comes out.
So here, we're putting a -3 into our function which means that
a 4(-3) + 4 comes out which simplifies to -12 + 4 or -8.
So h(-3) = -8 or the value of the function at -3 equals -8.

18-4=14
14+6=20
Answer:
[tex]\huge\boxed{\text{Maggie = 6 years, Brother = 21 years}}[/tex]
Step-by-step explanation:
We can create two equations based on the word problems, where [tex]m[/tex] is Maggie's age and [tex]b[/tex] is her brother's age.
[tex]m + b = 27[/tex]
[tex]b = 4m - 3[/tex]

13) Luis is wrong because he read the 80* as if his starting point was P. He needs to now take away 45 because that is the angle PTQ.
14) 165* I'm pretty sure because you just do 45 plus 60 since the centred one would only have a view of 45 from what I understand and the other two still have a view of 60 each. Total is 165.

The formula for the speed of a tsunami in deep water is v=gh−−√ , where g is acceleration due to gravity, 9.8 m/s2 , and h is the depth of the ocean in meters. Use this formula to estimate the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.
Answer:
v = 200 m/s
Step-by-step explanation:
The formula for the speed of a tsunami in deep water is given by :
[tex]v=\sqrt{gh}[/tex]
Here,
g is acceleration due to gravity
h is the depth of the ocean in meters.
We need to find the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.
It means we need to find v if h = 4000 m
So,
[tex]v=\sqrt{10\times 4000}\\\\v=200\ m/s[/tex]
So, the speed of the tsunami is 200 m/s.

-1 1/5 + -3/5 in simplest form
Answer:
-1 4/5
Step-by-step explanation:
In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction 3 5, the numerator is 3, and the denominator is 5. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.
