Step-by-step explanation:
The solution to this system of linear equations 3x – 2y = 14 and 5x + y = 32 is (x, y) is (6, 2).
Answer:
Step-by-step explanation:
If we choose to eliminate x, multiply the first equation by -3: -15x - 6y = 3
and multiply the second by 5: -15x - 35y = 55
Note that this allows us to eliminate x. We get:
-6y = 3
-35y = 55
which sum up to -41y = 58. Thus, y = -58/4.
For which problem situation could the equation 45x + 55x = 350 be used?
A 350 mile telephone cable costs $55 per mile for one section and $45 per mile for a different section. What is the total cost of the cable?
A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road. When will the two vehicles meet?
A 350 mile telephone cable is cut so the shorter piece is 45/55 of the whole cable. How long is each piece?
Two vehicles start from the same point traveling in the same direction. One vehicle travels 55 miles per hour (mph) and the other 45 mph. When will the two vehicles be 350 miles apart?
Answer:
45 x + 55 x = 350
x increases until the total equals 350
45 + 55 = 100 = relative speed of approach
(B) traveling cars meet this equation's specifications (x = 3.5)
The correct statement is option B)
What is the speed of an object?Speed is the rate at which an object's position changes, measured in meters per second. For example, if an object starts at the origin, and then moves three meters in three seconds, its speed is one meter per second. The equation for speed is simple: distance divided by time
Given here: The equation as 45x+55x=350
A car, traveling 45 mph, leaves Dallas heading for Odessa 350 miles away. At the same time, a truck leaves Odessa for Dallas traveling 55 mph on the same road.
Therefore the relative speed of the two trucks is given by 45+55=100
and let the time taken to meet is x then we can construct an equation as follows x=350/100
or, 45x+55x=350
Hence, The correct statement is option B)

the product of a number and three increased by four is the same as fourteen less than the product of twelve and a number
50 points, PLS ANSWER ASAP
Answer:
Let the number be x.
[tex]3*x+4=12*x-14[/tex]
[tex]3x+4=12x-14[/tex]
Subtract 4 from both sides:
[tex]3x+4-4=12x-14-4[/tex]
[tex]3x=12x-18[/tex]
Subtract 12x from both sides:
[tex]3x-12x=12x-18-12x[/tex]
[tex]-9x=-18[/tex]
Divide both sides by -9:
[tex]\frac{-9x}{-9} =\frac{-18}{-9}[/tex]

What is Number?A Number is an arithmetic value used for representing the quantity and used in making calculations.
Given that the product of a number and 3 is equal to the 14 less than product of twelve and that number.
Let the number be x
3x + 4 = 12x - 14
12x - 3x = 14 + 4
9x = 18
x = 2
Hence, the required number is 2.

Please help me solve this: y=8x 4x+y=48
Answer: x=4, y=32
Step-by-step explanation:
y=8x
4x+y=48
Plug in 8x for y in the equation
4x+8x = 48
Add like terms
12x= 48
Divide both side by 12
12x/12=48/12
x= 4
Then plug 4 back into the original equation in place of x
4(4)+y=48
16+y=48
Minus 16 from both sides
y= 48-16
y= 32
Answer: (4,32)
Answer: x = 4
Step-by-step explanation: 48 divided by 12 = 4
4 x 4 = 16
Y = 8x
8 x 4 = 32
32 + 16 = 48

Enter your answer as a mixed number in simplest form in the box.
Answer:
-10.6 or 53/5
Step-by-step explanation:
go ogle math
Answer: (3) 73/230
Step-by-step explanation:
You times whats in the brackets with 23 then remove the brackets which makes it = -71.3 - 23x = 5
Then i would swap the 23x and 5 around which makes it = 71.3 - 5 = 23x
subtract 71.3 - 5
-76.3 = 23x
Divide -76.3 by 23 (Use a calculator) =
(3) 73/230
Thats how simplified it can go. (fraction cant be simplified more)
(3) is the leftover whole number that is next to the mixed number
