-7x – 2y = 14
6х + бу = 18
Answer:
es 8 ksnfjskausksufbab 726+47272774
Answer:
(x. y) =(4, 7)
Step-by-step explanation:
-7 x - 2 y = 14
6 x + 6 y = 18
Solve the equation
x = - 2/7 y
6 x + 6 y = 18
Substitute the value of x
6 ( - 2 - 2/7y) + 6 y = 18
Solve the equation
y = 7
Substitute the value of y
x = - 2 - 2/7 x 7
Solve the equation
x = - 4
A possible solution is
(x, y) = (- 4, 7)
Check the solution
- 7 x ( - 4) - 2 x 7 = 14
6 x ( - 4) + 6 x 7 = 18
Simplify
14 = 14
18 = 18
The ordered pair is the solution
(x, y) = ( - 4, 7)
Boom!
Which is the proportion for the ratio 3/6
15/18
3/12
9/18
124 students played a sport in the fall, and 76 students played a sport in the spring. What was the percent decrease of the students who played sports in the spring? Round your answer to the nearest tenth of a percent.
Answer:
5.7%
Step-by-step explanation:
subtract 124-76.
then, you would divide 76 by 124 to get a weird number so multiply that by 100 to get this.
5.64516129.
then rounding to the nearest tenth would be 5.7.
so i think it would be 5.7%.
can somebody help with this no fake answers please im kinda low
In a survey of the students in a class, it was found that 9 students worked during summer holidays. If this represents 25% of the class, how many students are there in the class?

x=9×100/25
x=9×4
x=36
so total students are 36

Find the value of g(4) for the function below:
g(x) = x² – 2x + 5
O 5
O 13
O 19
O 25
Answer:
O 13
Step-by-step explanation:
g(4) is asking for the function of g when x = 4
g(4) = (4)^2 - 2(4) + 5
g(4) = 16 - 8 + 5
g(4) = 13

Given a term in an arithmetic sequence and
the common difference find the 100th term.
a14= 102
d = 10
Please help, i’m struggling.
Answer:
100th term = 962
Step-by-step explanation:
You need to find the first term of the sequence
The formula to use is
[tex]a_{n} = a_{1} + (n - 1)d[/tex] In your problem, n = 14. So,
[tex]102 = a_{1} + (14 - 1)10\\102 = a_{1} + 130\\a_{1} = -28\\\\[/tex]
Now you can find the 100th term. n = 100, first term = -28 and d = 10
[tex]a_{100} = -28 + (100 - 1)10\\ = -28 + 990\\ = 962[/tex]
100th term = 962
how do you graph x+ 4
simplify the following expression
[tex]( {5}^{3} ) {}^{5} [/tex]
Answer:
[tex]5^{15}[/tex]
Step-by-step explanation:
[tex](a^{m})^{n}=a^{m*n}\\\\(5^{3})^{5}=5^{3*5} = 5^{15}[/tex]
A young sumo wrestler decided to go on a special diet to gain weight rapidly. He gained weight at a constant rate.
The table compares the wrestler's weight (in kilograms) and the time since he started his diet (in months).
How fast did the wrestler gain weight?
___ kilograms per month
Finding the rate of the weight gain, we divide the total weight gained with the total number of months that took to gain that weight.
Total time (months) = 0.5 + 2 + 3.5 = 6 months
Total weight (kg) = 80.6 + 88.4 + 96.2 = 265.2 kilograms
Rate = Kg ÷ Months
Rate = 265.2 ÷ 6 = 44.2
44.2 kilograms per month
Cheers!
Answer:
78 kilograms
