8th pre-algebra math
Answer:
The first one
Step-by-step explanation:
Marcus has earned 353 out of 400 points (88% or B+) in Math class. He needs 90% to earn an A-. There is one test left worth 100 points. How many points does Marcus need on the test to raise his grade to an A-?
Answer:
97
Step-by-step explanation:
Marcus is aiming for an A- (90-94 percent). The question states that there is another test awaiting that is worth 100 points. In order to find the answer to the question, you need to:
1.) Add 400 + 100, to show how many points there are in total.
2.) Use the answer choices and add it to 353.
88 + 353 = 441
93 + 353 = 446
97 + 353 = 450
3.) Find the percentage of the sums.
441/500 = 88%
446/500 = 89%
450/500 = 90%
Since Marcus is aiming for an A-, we can conclude that obtaining 97 points will help Marcus achieve an A-.

−5.6x=−4
What is the solution to the equation?
Enter your answer as a simplified fraction in the box.
Answer: 0.714285
Step-by-step explanation:
The solution of the equation (-5.6 = -4) is (x = 5/7) and this can be determined by using the arithmetic operations.
Given :
-5.6x = -4
The following steps can be used in order to determine the solution to the equation (-5.6x = -4):
Step 1 - The arithmetic operations can be used in order to determine the solution to the given equation.
Step 2 - Write the given equation.
-5.6x = -4
Step 3 - Add 4 on both sides in the above equation.
-5.6x + 4 = -4 + 4
-5.6x + 4 = 0
Step 4 - Add 5.6x on both sides in the above expression.
-5.6x + 4 + 5.6x = 5.6x
4 = 5.6x
Step 5 - Divide 4 by 5.6 in the above expression.
[tex]x = \dfrac{4}{5.6}[/tex]
Step 6 - Simplify the above expression.
[tex]x = \dfrac{5}{7}[/tex]

If the perimeter of a regular pentagon can be expressed as 10s - 20, determine the length of each side.
50 s - 100
5 s - 10
s - 2
2 s - 4
Answer:
2 s - 4
Step-by-step explanation:
A Regular pentagon means that it has 5 evenly lengthen sides. In other words, the shape with 5 sides has lengths are equal to each other.
Because the total perimeter as mentioned of the pentagon is 10s - 20,
dividing it by 5 should find the length of each side!
Equation: (10s - 20) / 5
Once you finish dividing each digit inside the bracket you are done!
= 2s - 4
So that leaves us with 2s-4
Answer:
2 s - 4

Mikey's family is taking a road trip. Their car can travel no more than 260 miles without needing to refill the gas tank. They have traveled 112 miles since they last filled the gas tank.
Mikey knows that the inequality representing this situation is 112 + x ≤ 260.
Select from the drop-down menu to correctly interpret the solution of this inequality.
Mikey's family can drive_____more miles before they need to refill the gas tank.
A. at most 148
B. at least 148
C. more than 372
D. more than 372
Answer:
A
Step by step:
you subtract 112 from 260 to isolate the variable. Then you get x is less than or equal to 148. Which means that the most miles that can be traveled is 148 miles before filling up.
Mikey's family can drive at most 148 more miles before they need to refill the gas tank. which is the correct answer would be option (A).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
As per the given situation, the required inequality would be as
⇒ 112 + x ≤ 260
To isolate the variable, remove 112 from 260. The result is that x is less than or equal to 148.
⇒ 112 + x - 112 ≤ 260 - 112
⇒ x ≤ 148
This indicates that the maximum distance that may be traveled before filling up is 148 miles.
Therefore, his family can drive at most 148 more miles before they need to refill the gas tank.

An account with an initial balance of $4000 earns 6.5% interest for 5 years.
What is the ending balance?
Enter your answer in the box. $.
Answer:
The balance in the bank after 5 years of 6.5% interest is $5,300.
Step-by-step explanation:
*Presuming that this is not a compounding interest the interest would just multiply by the even balance.*
So every 5 years the balance earns 0.065 of 4,000 dollars.
This would make our equation:
4000 + (4000 x .065 x 5 )
= 4000 + (1300)
= 5300
The balance in the bank after 5 years of 6.5% interest is $5,300.

5,300

The value of the x is -2 after solving the linear equation by using the elimination method.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
The linear equations are:
2x+3y=8
6x−5y=−32
3X(2x+3y=8)
6x + 9y = 24
6x−5y=−32
14y = 56
y = 4
x = -2
Thus, the value of the x is -2 after solving the linear equation by using the elimination method.

Todd and his friends are painting 5 equal sections of a wall. The wall is 10 feet tall, but its length is unknown.
Each section will be a different color, so they need to know the area of each section.
so , i said 5/10x area = length * width A=10*x a= 10x
then i said you should divide , next i said 10x/5 10x in five sections is 2 in each q1 said area 10*x but x=2 so 10*2=20 is this correct?
