The value of (3x + 2) when (7 + x = 5) is -4.
What is a expression? What is a mathematical equation? What is Equation Modelling?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have the following equation as -
x + 7 = 5
We can write -
x + 7 = 5
x = 5 - 7
x = - 2
Now, we have to find -
3x + 2
3(-2) + 2
- 6 + 2
- 4
Therefore, the value of (3x + 2) when (7 + x = 5) is -4.

What is the slope of the line that passed through the points (-3,-3) and (-5,-2)
Answers
Answer: -1/2
Step-by-step explanation:
Formula for finding slope: (y1 - y2) / (x1 - x2).
This is because the slope is the change of y and x values, so we shall find the difference between the y and x points.
Let x1 be -3, and y1 be -3, and the second point- let x2 be -5, and y2 as -2.
We plug them in and we get (-3 - (-2)) / (-3 - (-5)).
= -1 / 2

Here,
In 2010, the average attendance at a Washington capitals hockey game was 18,397.
This year, the average attendance was 18,506.
Percentage change = 18506 - 18397/18397 × 100%
= 0.608%
Thus, the requried percentage change in attendance increase from 2010 to now is 0.608%.

Tyler has $4.50 in a bank in his bedroom. Each day he adds $1.50 to it. Which equation can be used to find out how many days it will take for Tyler to save $30.00?
Answers
Answer:
See belowStep-by-step explanation:
Given:
Initial amount is $4.50Adding every day $1.50Number of days is xFinal amount is $30The equation we need:
4.50 + 1.50x = 30Solve to find the number of days:
1.50x = 30 - 4.501.50x = 25.50x = 25.50/1.50x = 17 daysTyler's Initial amount = $ 4.50
He adds every day = $ 1.50
The final amount will be = $ 30.00
The number of days is = x
In mathematical expression,
→ 4.50 + 1.50x = 30
Now we have to,
→ find out how many days it will take for Tyler to save $ 30.00?
Let's solve the equation,
→ 4.50 + 1.50x = 30
→ 1.50x = 30 - 4.50
→ 1.50x = 25.50
→ x = 25.50/1.50
→ [ x = 17 ]
Hence, it will take 17 days to save $ 30.

Using the sum of the sides of the triangle, it is found that the correct option is:
D) Yes; 3.8 + 7.4 is greater than 11.
What is the condition of the sum of the sides of the triangle?In a triangle, the sum of the lengths of the two smaller sides has to be greater than the length of the greater side.In this problem:
The lengths of the smaller sides are 3.8 and 7.4.Of the greater side, is 11.Hence:
[tex]3.8 + 7.4 = 11.2 > 11[/tex], which means that these lengths can represent a triangle and option D is correct.

Step-by-step explanation:
(-3.6x + 9.4) - (1.9x + 3.6)
(-3.6x + 9.4) - 1.9x - 3.6
-5.5x + 5.8
The required difference between linear expressions is -5.5x + 5.8.
What is the linear expression?Linear expressions are mathematical statements with a minimum of two terms containing variables or numbers.
The linear expressions are given in the question
(-3.6x + 9.4) - (1.9x + 3.6)
We have to determine the difference between linear expressions
(-3.6x + 9.4) - (1.9x + 3.6)
Distribute the negative sign in the above expression
-3.6x + 9.4 - 1.9x - 3.6
Rearrange the terms of variable x in the expression
-3.6x - 1.9x + 9.4 - 3.6
Apply the arithmetic operation in the likewise terms
-5.5x + 5.8
Therefore, the required difference between linear expressions is -5.5x + 5.8.

fill in the blank to make the two fractions equivalent. 4/5 = ?/25
Answers
Answer:
20
Step-by-step explanation:
5 times 5 is 25 so that is the bottom and 4 times 5 is 20, so it is 4/5 and 20/25.
Answer:
20
Step-by-step explanation:
First 4x5 =20 which means it's going to be 20/25 if you don't understand let me help. You probably know that the number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.
Here's a little tip for you. Any number can be converted to fraction if you use 1 as the denominator:
25
1
So now that we've converted 25 into a fraction, to work out the answer, we put the fraction 4/5 side by side with our new fraction, 25/1 so that we can multiply those two fractions.
That's right, all you need to do is convert the whole number to a fraction and then multiply the numerators and denominators. Let's take a look: 4 x 25
5 x 1
=
100
5
In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.
You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 100 and 5 is 5.
We can now divide both the new numerator and the denominator by 5 to simplify this fraction down to its lowest terms.
100/5 = 20
5/5 = 1
When we put that together, we can see that our complete answer is:
20

The complete and simplified answer to the question what is 4/5 of 25 is:

n Ms. Salmon’s 4th grade class, there are half as many boys as there are girls. There are 30 students all together. How many are boys? How many are girls? Explain how you solved the problem.
Answers
Answer:
10 boys, 20 girls
Step-by-Step Explanation:
So there are 30 students
Our first assumption is 15 boys, 15 girls. 50-50, right?
But there are half as many boys as girls.
So there's twice as many girls in the class.
Let's have B = boys and G = girls
B + 2G = All 30 Students
2G = 2/3 (20/30)
B = 1/3 (10/30)
20 + 10 = 30
10 boys, 20 girls.
Hope this helps! I suggest asking your teacher for help just to make sure you understand it.
