Step-by-step explanation:
5 = x + 3. The product of 2 times a number is 10. 2x = 10. One half a number is 10 x/2 = 10. Five times the sum of x and 2 5(x + 2). Seven is greater than x.
Answer:
35
Step-by-step explanation:
This is how you can solve for the missing number that is doubled: ( x )
7 = 3 + 2x
7 ( -3 ) = 3 ( -3 ) + 2x
4 = 2x
4 ( /2 ) = 2x ( /2 )
2 = x
This is how you solve for the number the question is asking for: ( y )
y = 5 ( 3 + 2x )
y = 5 ( 3 + 2 ( *2 ))
y = 5 ( 3 + 4 )
y = 5 ( 7 )
y = 5 * 7
y = 35

A group of 55 football players was polled about which synthetic grass they like to play on, Chemgrass or Chemstrand. The data from the survey is shown in the Venn diagram. Use the Venn diagram to find the missing values in the frequency table. A circle labeled chemstrand 15 overlaps a circle labeled chemgrass 17. Overlap is labeled 13. 4-column table with 3 rows. First column has no label with entries likes chemgrass, does not like chemgass, total. Second column is likes chemstrand with entries x, z, 28. Third column is does not like chemstrand with entries y, 10, 27. Fourth column is total with entries 30, 25, 55. What are the values of x, y, and z? x = 17, y = 15, and z = 13 x = 13, y = 15, and z = 17 x = 15, y = 13, and z = 17 x = 13, y = 17, and z = 15
Answer:
From the Venn diagram: 15 players like Chemstrand, 17 players like Chemgrass, 13 players like both Chemstrand and Chemgrass while 10 players like neither Chemstrand nor Chemgrass.
The missing values in the frequency table are x - representing the number of players that like both Chemstrand and Chemgrass, y - representing the number of players that like Chemgrass but do not like Chemstrand and z - representing the number of players likes Chemstrand but do not like Chemgrass.
The number of players that like both Chemstrand and Chemgrass is 13. The number of players that like Chemgrass but do not like Chemstrand is 17. The number of players likes Chemstrand but do not like Chemgrass is 15.
Therefore, x = 13, y = 17 and z = 15
The values of x, y, and z from the Venn diagram are:
x = 13, y = 15, and z = 17.
What is a Venn diagram?A Venn diagram is an overlapping circle to describe the logical relationships between two or more sets of items.
We have,
From the Venn diagram, we can see that:
The total number of players who like Chemgrass is 17 + 13 = 30.
The total number of players who like Chemstrand is 13 + 15 = 28.
The total number of players who do not like Chemgrass is 10 + 13 = 23.
The total number of players who do not like Chemstrand is 10 + 17 = 27.
The total number of players is 55.
Now,
We can fill in the missing values in the frequency table using the information above:
The value of x (the number of players who like both Chemgrass and Chemstrand) is the overlap between the two circles, which is 13.
The value of y (the number of players who like Chemstrand but not Chemgrass) is the number of players who like Chemstrand (28) minus the number of players who like both (13), which is 15.
The value of z (the number of players who like Chemgrass but not Chemstrand) is the number of players who like Chemgrass (30) minus the number of players who like both (13), which is 17.
Therefore,
The values of x, y, and z are x = 13, y = 15, and z = 17.

______ * 7/4 = 1
-7/4
4/7
7/4
-4/7
Answer:
7/4
Step-by-step explanation:
[tex]x\cdot \frac{7}{4}=1\\\\x\cdot \frac{7}{4}\cdot \frac{4}{7}=1\cdot \frac{4}{7}\\\\x\cdot 1 = \frac{4}{7}\\\\x=\frac{4}{7}[/tex]
Answer:
The answer is [tex]\frac{4}{7}[/tex].
Step-by-step explanation:
Due to the end result being 1, we can sufficiently say it is neither -7/4 nor -4/7, due to a positive number multiplied by a negative number always equating to a negative number.
Therefore, using the Multiplicative Inverse Property, we can find the result by dividing 1 over [tex]\frac{7}{4}[/tex]:
[tex]\frac{1}{\frac{7}{4}}[/tex]
[tex]= \frac{4}{7}[/tex]
Hence, the answer is [tex]\frac{4}{7}[/tex].

Dimitri scored 44% of the points in two person basketball game against another team. His partner scored the rest of the points . If dimitri scored 22 points how many points did his partner score
Dimitri and his partner scored a total of points during the game so his part scored points
Answer:
28
Step-by-step explanation:
44/100×x=22
x=50
x=total goals scored
50-22=28
Dimitri and his partner scored a total of points will be are 50. So, his part scored points will be 28.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.
Dimitri scored 44% of the places in a two-man b-ball game against another group. His accomplice scored the other focuses. On the off chance that Dimitri scored 22 focuses the number of focuses that did his accomplice score.
Let 'x' be the total scored. Then the equation is given as,
44% of x = 22
0.44x = 22
x = 50
The points scored by his partner will be given as,
⇒ 50 - 22
⇒ 28
Dimitri and his accomplice scored a sum of focuses will be 50. In this way, his part scored focus will be 28.

The Choi family wants to save money to travel the world. They purchase an annuity with a monthly payment of $65 that earns 4.5% interest, compounded monthly. Payments will be made at the end of each month. Find the total value of the annuity in 11 years.
Answer:
You can get an idea of how much guaranteed lifetime income a given amount of savings will buy by going to this annuity payment calculator. Today, for example, $100,000 would get a 65-year-old man about $525 a month in lifetime income, while that amount would generate roughly $490 a month for a 65-year-old woman.
Answer: $8966.10
Step-by-step explanation:
The monthly payment with interest is 67.925. Multiply that by 12 for the 12 months in a year. You should get 815.10 as your yearly payment. And finally multiply 815.10 by 11 for the 11 years. You should get 8966.10 as your final answer. I hope this helps!

Max invests some money in a savings bond.
The savings bond pays interest at a rate of 2% per year.
At the end of the first year, his savings bond is worth £5763
(b) How much money did Max invest in the savings bond?
Answer:
£5650
Step-by-step explanation:
The money max invested in the saving bond = x
After one year the intrest will be 2% of x
Amount = £5763
Amount = Principcal + Interest
= £5763 = x + 2% multiplied x
£5763 = x + 2x/100
= 50x/50 + x/50 = 5763
= 51x/50 = £5763
51x = 5763x50
51x = 288, 150
x = 288,150/51
x = 5650
So the money max invested = £5650
Carlos graphed f(x) = -3x + 8 and g(x) = 7x - 2 on
a coordinate plane. What is the solution of the functions?
1
1.5
3
5
Step-by-step explanation:
When f(x) = g(x), -3x + 8 = 7x - 2.
=> 10x = 10, x = 1.
The solution of the functions is 1.
The solution to functions f(x) = -3x + 8 and g(x) = 7x - 2 graphed by Carlos is x = 1
The given functions graphed by Carlos are:
f(x) = -3x + 8
g(x) = 7x - 2
The solution to the functions is the point where the two functions intersect on the graph
To get the point where the two functions intersect, equate f(x) and g(x).
That is, f(x) = g(x)
-3x + 8 = 7x - 2
Collect like terms:
7x + 3x = 8 + 2
10x = 10
Divide both sides by 10
10x / 10 = 10/10
x = 1
The solution to functions f(x) = -3x + 8 and g(x) = 7x - 2 graphed by Carlos is x = 1

x + 7 = 0
x = -7
x - 1 = 0
x = 1
The x-intercepts are -7 and 1.
