Answer:
x=3, y= - 2
Step-by-step explanation:
4x + 3y = 6
x-3y= 9
x=9+3y
4.(9+3y)+3y=6
36+12y+3y=6
15y = - 30
y = - 2
=> x= 9+3y
x= 9+ 3.(- 2)
x= 3

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

Answer:
25 and 80
Step-by-step explanation:
180 - 75 = 105
105 / (5+16) = 5
multiply each side of the ratio 5:16 by 5

Montana is known for having very chilly winters. One night, the temperature was falling by 2 degrees Fahrenheit each hour. At sunset, the temperature was -5 degrees Fahrenheit. How many hours will it take for the temperature to reach -19° F?
Answer:
7 hours
Step-by-step explanation:
We are given that
At sunset, the temperature=-5 degrees Fahrenheit
Each hour, temperature falling=2degrees Fahrenheit
We have to find time taken to reach the temperature -19° F.
Let x be the time time taken to reach the temperature -19° F
According to question
[tex]-5+x(-2)=-19[/tex]
Where we taking 2 negative because temperature decreases.
[tex]-5-2x=-19[/tex]
[tex]-5+19=2x[/tex]
[tex]14=2x[/tex]
[tex]x=\frac{14}{2}[/tex]
[tex]x=7[/tex]
Hence, it will take 7 hours for the temperature to reach -19° F.
9x - 4y= 19
4x + 4y= 20
Answer:
x=3 and y=2
Step-by-step explanation:
9x - 4y= 19
4x + 4y= 20
add both equations;
13x = 39
x= 3
using 4x + 4y= 20;
4(3) +4y=20
12+4y=20
4y= 20-12=8
y=8/4=2

Step-by-step explanation:
To find the missing leg, we need to use a^2 + b^2 = c^2.
Let's call the missing leg a, and then substitute the numbers the other numbers
a^2 + 12^2 = 13^2
Simplify
a^2 + 144 = 169
To solve, subtract 144 from both sides (169-144)
a^2 = 25
This means that a squared is 25; to find a, we need to find the square root of 25.
a = 5
Your answer is 5.
Answer:
5m
Step-by-step explanation:
set it up
[tex]12^{2}[/tex]+[tex]a^{2}[/tex]=[tex]13^{2}[/tex]
do what you know
equation becomes: 144+[tex]a^{2}[/tex]=169
subtract both sides by 144
equation becomes [tex]a{2}[/tex]=25
square root both sides
equation becomes: a=5

A toy manufacturer is going to produce a toy that is a scale model of the giant robot in last summer's super hero movie, where 1 cm = 6 feet. If the robot in the movie was 36 feet tall, what will be the height of the toy?
Answer:
182.88 cm
Step-by-step explanation:
36/6 is 6 and 182.88 are in 6 feet
5.977cm will be the height of the toy when a toy manufacturer is going to produce a toy that is a scale model of the giant robot in last summer's super hero movie.
when 1 cm = 6 feet. If the robot in the movie was 36 feet tall, then we need to find the height of the toy.
What is 1 feet = ___cm?1 feet = 1/6cm=0.1666cm.
From given,
when 1 cm = 6 feet. If the robot in the movie was 36 feet tall, then we need to find the height of the toy.
then 1 feet = 1/6cm=0.1666cm
As 1 feet is 0.1666 cm , to find for 36 feet we need to multiply 1 feet value with 36.
If it is 36 feet =36*0.1666=5.977cm
Therefore 5.977cm will be the height of the toy.
