The age of Mary and the age of Beth will be 10 years and 4 years, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Three times Mary’s age added to Beth’s age is 34 years. Half of Mary’s age minus Beth’s age is 1 year.
Let 'x' be the age of Mary and 'y' be the age of Beth. Then the equations are given below.
3x + y = 34 ...1
x/2 - y = 1 ...2
From equations 1 and 2, then we have
3(2y + 2) + y = 34
6y + 6 + y = 34
7y = 34 - 6
7y = 28
y = 4
Then the value of the variable 'x' is given as,
3x + 4 = 34
3x = 30
x = 10
The age of Mary and the age of Beth will be 10 years and 4 years, respectively.

Josephine is taking a college course, and her professor bases the course grade on the average of 2 tests taken in the semester. She wants to know what she needs to earn on the last test to maintain her grade. Rearrange the following equation for b, where C is the average of 2 test scores, a and b. C=a+b/2
Please DO NOT say that this has already been answered, the answer options were different than this question.
Options:
a.) b = 2C/a
b.) b = 2C + a
c.) b = 2C - a
d.) b = 2C(a)
The equation C=a+b/2 can be rearranged for b as b=2C - a. Therefore, option C is the correct answer.
We need to rearrange an equation C=a+b/2 for b, where C is the average of 2 test scores, a and b.
What is an average?By definition, an average is the arithmetic mean of the sum of all the values divided by the total number of values in a given set. An average is calculated for those sets of values which are more or less the same. The term average describes the numeric value that represents a large amount of data. An average can be derived by calculating the ratio of the sum of all the values to the number of units or values.
The equation C=a+b/2 can be rearranged for b as follows:
Now, C=a+b/2
⇒2C=a+b
⇒b=2C - a
The equation C=a+b/2 can be rearranged for b as b=2C - a. Therefore, option C is the correct answer.

X + (-4) = -2
What does X repesents??? Please help
Answer:
x=2
Step-by-step explanation:
x+(-4) is the same as x-4
First you have to get X alone so you add 4 to both sides because when you add 4 to both sides it will take away the 4 on the x side.
x-4=-2
+4 +4
x= -2+4 or you can see this as 4-2 which is 2

9. The two figures below have a scale factor of 3 : 2. What is the value of x?
The value of x can be found by setting up a proportion based on the given scale factor of 3:2 is 16/3 units.
The breadth of the first parallelogram is 8 and the breadth of the second parallelogram is x.
Setting up the proportion, gives:
8/3 = x/2.
To solve for x, cross-multiply:
[tex]8 \times 2 = 3 \times x.[/tex]
Simplifying the equation, gives:
16 = 3x.
Next, divide both sides of the equation by 3 to isolate x:
x = 16/3.
Therefore, the value of x is 16/3.

The value of y when solving the equation 2(y−6)+3=4y−7 is:
Answer:
-1
Step-by-step explanation:
2(y−6)+3=4y−7
2y−12+3=4y−7
2y-12+12+3=4y-7+12
2y+3=4y+5
2y+3-3=4y+5-3
2y-4y=4y-4y+2
-2y=2
-2y/-2=2/-2
y=-1
The value of y in the given algebraic expression when simplified is; y = -1
How to Solve Algebraic Problems?We are given the algebraic expression;
2(y − 6) + 3 = 4y − 7
Expand the bracket to get;
2y − 12 + 3 = 4y − 7
Use addition property of equality to add 12 to both sides to get;
2y - 12 + 12 + 3 = 4y - 7 + 12
2y + 3 = 4y + 5
Subtract 3 from both sides to get;
2y + 3 - 3 = 4y + 5 - 3
2y = 4y + 2
4y - 2y = -2
2y = -2
y = -2/2
y = -1
