Here is the algebraic solution:
T is the tens digit
O is the ones digit
T+O = 14
So O = 14 - T <---- this is the first equation
The original number is 10*T + O
If the digits are reversed the original number is increased by 18.
The number if the digits are reversed is:
10*O + T = 10*T + O + 18
10*(14-T) + T = 10*T + (14-T) + 18 <--- substitutes O with 14-T per first equation above in bold
140 - 10T + T = 10T + 14 - T + 18 <--- distributive left side
140 - 9T = 9T + 32
140 = 9T + 9T + 32
140 - 32 = 9T + 9T
108 = 18T
108/18 = T
T= 6
THe tens digit is 6.
The ones digit must be 8.
Reversing 86 - 68 = 18
The original number is 68.

10. 63 + 9(6x - 5).= 6(5x + 8) - 6x
Is it no solution/many solutions/ or one solution
Answer:
one solution: x=1
Answer:
one solution
Step-by-step explanation:
10.63 + 9(6x - 5) = 6(5x + 8) - 6x
10. 63 + 54x - 45 = 30x + 48 - 6x
-34.37 + 54x = 24x + 48
54x = 24x + 48 + 34.37
54x = 24x + 82.37
54x -24x = 82.37
30x = 82.37
x = 2.745

How do you convert 15 feet to centimeters?
Answer:
Multiply 15 feet by 12 to convert the 15 feet into 180 inches. Then, convert those inches into centimeters by multiplying 180 into 2.54. The result should be 457.2. Another way to do it is by multiplying 15 feet by 30.48 to get your answer directly.

Janice went shopping at the mall. At the first store, she spent half her money. At the second store, she spent $2.50. If she had $6.75 after the second store, how many dollars did she start with?
6.75+2.50=9.25
9.25(2)=18.5
answer: $18.50
The amount in dollars Janice started with is $18.50.
How to determine the amount used to startLet's break down the information given in the problem and set up an equation to solve for the amount of money Janice started with.
At the first store, Janice spent half her money.
At the second store, she spent $2.50.
After the second store, she had $6.75 left.
Let "x" be the amount of money Janice started with.
At the first store, she spent half her money: She spent 0.5x.
At the second store, she spent $2.50.
After the second store, she had $6.75 left.
We can set up an equation based on these steps:
Initial money - Money spent at the first store - Money spent at the second store = Remaining money
x - 0.5x - 2.5 = 6.75
Combine the terms with "x":
0.5x - 2.5 = 6.75
Add 2.5 to both sides:
0.5x = 9.25
Now, divide both sides by 0.5 to solve for "x":
x = 9.25 / 0.5 = 18.5
So, Janice started with $18.50.

A rectangle with sides 4 cm and 7 cm was enlarged in the ratio 1:2
The area of a rectangle with sides 4 cm and 7 cm was enlarged in the ratio 1:2 is 56cm².
What is a ratio?Ratio demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B). This indicates that you're dividing information A by B. For instance, the ratio will be 5/10 if A is 5 and B is 10.
From the information, a rectangle with sides 4 cm and 7 cm was enlarged in the ratio 1:2.
New Length = (2 × 7cm) = 14cm
New width = (1 × 4cm) = 4cm
Therefore area will be:
= Length × Width
= 14cm × 4cm
= 56cm²
The area is 56cm².

The graph shows the relationship between time and the number of soda bottles a machine can make. Use the points (3,135) and (6,270) to find the number of soda bottles the machine can make each minute.
Answer:
45 bottles per minute
Step-by-step explanation:
the number of bottles per minute would equal the rate of change, or 'slope'
the slope formula is 'the difference of the two y-values / difference of the two x-values'
(270-135) / (6-3) = 135/3 or 45 bottles per minute

what is 4(2) for the function f(2)=3x+5
Answer: 11
Assuming 4(2) is meant to be f(2).
Step-by-step explanation:
I'm not sure what 4(2) means. I'll assume f(2) was intended in this answer.
We have a function, f(x)=3x+5, where the value of the function depends on the value of x. f(2) means x=2, so we would write:
f(2)=3x+5
f(2)=3*(2)+5
f(2)=6+5
f(2)=11
