Answer:
x + 17 = 25
Step-by-step explanation:
x is "a number" and you just add it to 17. (Also the answer would be 8 if you need to solve it too)
The algebraic expression is x + 17 = 25 and the number is 8 if the number plus 17 is 25.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have:
A number plus 17 is 25 algebraic expressions:
Let x be the number:
x + 17 = 25
After solving:
x = 25 - 17
x = 8
Thus, the algebraic expression is x + 17 = 25 and the number is 8 if the number plus 17 is 25.

I've asked this question twice and gotten 2 different answers. this is sooo urgent and I don't know what the right answer is. A long-distance phone company charges $4.95 month plus an additional $.10 per minute. a. Define a variable and write a formula to find the total cost per month for long-distance service. b. Use this formula to find the long-distance charges for 120 minutes of calls in one month.
Answer:
C=4.95 +0.10x, where x=minutes
C=4.95 + 120(0.10)
C=4.95 +12.00=$16.95

PLEASE HELP!!!! On average, Jack can fold his laundry in 30 minutes, but, depending on how much laundry he has, his time can vary from the average by 10 minutes.
Which absolute value equation can be used to calculate Jack's maximum and minimum time to fold his laundry?
Let x represent the maximum and minimum time.
|x−30|=10
|x+10|=30
|x−10|=30
|x+30|=10
Answer:
I think it is the third choice
The absolute value equation can be used to calculate Jack's maximum and minimum time to fold his laundry is, |x−30|=10. So, Option A is correct
What is an Equation ?An equation is a mathematical term, which indicates that the value of two algebraic expressions are equal. There are various parts of an equation which are, coefficients, variables, constants, terms, operators, expressions, and equal to sign.
For example, 3x+2y=0.
Types of equation
1. Linear Equation
2. Quadratic Equation
3. Cubic Equation
Given that,
On average, Jack can fold his laundry in 30 minutes
How much laundry he has, his time can vary from the average by 10 minutes
So, maximum time can be 40 minutes
And minimum time can be 20 minutes
Therefore, The result is |x-30| =10

Nicholas has some cans at home to donate to the soup kitchen, but he decides to start a can drive at his school to see if other students will help. The table represents the number of cans donated, y, which is dependent on the number of days cans are collected, x.
A 2-column table with 3 rows. Column 1 is labeled x with entries 4, 7, 10. Column 2 is labeled y with entries 955, 1660, 2365.
Find the linear equation that represents the scenario.
Answer:
y = 235x + 15
Step-by-step explanation:
Equation of a Line
The equation of the line in slope-intercept form is:
y=mx+b
Where:
m = slope
b = y-intercept.
The point-slope form of the equation of a line is:
y - k = m ( x - h )
Where m is the slope and (h,k) is a point through which the line passes.
We are given 3 points and we must provide the equation of the line that passes through them all in slope-intercept form.
Selecting the points (4,955) and (7,1660) we can calculate the slope of the line by using the formula:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\displaystyle m=\frac{1660-955}{7-4}=\frac{705}{3}=235[/tex]
Now we use the point-slope equation with the first point (4,955):
y - 955 = 235 ( x - 4 )
Operating:
y - 955 = 235x - 940
y = 235x - 940 + 955
y = 235x + 15
The third point (10,2365) should pass through this line. To verify, substitute:
2365 = 235(10) + 15 = 2350 + 15= 2365
Since the identity is true, the equation is correct:

y = 235x + 15

Sam builds 360 toys in 8 hour. At that rate,how many toys would he build in 4 minutes
Answer:
He can build 3 toys in 4 minutes.
Step-by-step explanation:
Divide 360 by 8 since you are dividing it first to get the number of toys he can build in an hour. As a result, he can build 45 toys in an hour. Divide that number by 15 since 4 times that number equals an hour. You should get 3 toys as your final result.
For easier explanation, multiply 8 and 15 together to get 120 for better understanding. Divide that number from 360 to get the same answer.

The probability of getting a 6 is 4/5. The dice is rolled 500 times How many sixes would you expect to roll
Answer: 400
Step-by-step explanation:
From the question, we are informed that the probability of getting a 6 is 4/5 and that the dice is rolled 500 times.
The number of sixes that would be expected to roll will be 4/5 multiplied by the number the dice is rolled
= 4/5 × 500
= 400
There'll be 400 sixes.
Rahan is on holiday in the USA. He has $200 to spend on clothes.
Rehan buys. 1 pair of trainers costing $60. 3T. shirts costing $25 each.
He also wants to buy a jacket costing $80
Has Rehan got enough money to buy the jacket
Rahan doesn't have enough money that'll be required in buying the jacket.
Total Amount with Rahan = $200
Total amount of expenses = (1 × $60) + (3 × $25) + $80
= $60 + $75 + 80.
= $215
In this case, since Rahan has $200, then he doesn't have enough money that he'll use in buying the jacket.

Hey guys can one of you help me pls it’s only one small question
Answer: x=6
Step-by-step explanation:
-6x+8=4(5-x)
-6x+8=20-4x
12=2x
x=6
Answer:
-6
Step-by-step explanation:
-6x+8=20-4x
subtract 8 from both sides:
-6x+8-8=20-4x-8
simplifiy:
-6x=-4x+12
Add 4x to both sides:
-6x+4x=-4x+12+4x
simplifiy:
-2x=12
divied both sides by -4:
-2x/-2=12/-2
simplifiy:
x=-6

Hey there!
16 1 / 4% = 16(4) + 1 = 64 + 1 = 65
65 / 4% = 16.25%
• Percentages usually run out of 100
16.25 / 100
• Finding out the ratio of your given number, multiply the numerator and denominator by the number 4
16.25 * 4 / 100 * 4
16.25 * 4 = 65 (numerator)
100 * 4 = 400 (denominator)
• Equation: 65 / 400
• REDUCE the GIVEN FRACTION (65/400)
• Once when you have the fraction reduced you should have came up with: 13/80 (aka your answer)
• Answer: 13/80 ☑️
