Answer:
See below.
Step-by-step explanation:
I can't see any example but what I would do is first multiply both sides by 3.
4m/3 = 8
4m/3 * 3 = 8 * 3
4m = 24.
The first operation in solving the equation 4m/3 = 8 is multiplying both sides of the equation by 3, which eliminates the fraction and isolates the variable 'm'. After further simplification, the solution to the equation is m = 6.
Explanation:To solve the equation 4m/3 = 8, the first operation we need to perform is to isolate the variable on one side of the equation. We can do this by multiplying both sides of the equation by 3. This cancels out the fraction on the left side, allowing us to solve for 'm'.
In step by step:
Multiply both sides of the equation by 3: (4m/3) * 3 = 8 * 3.This simplifies to 4m = 24.Finally, we divide both sides by 4 to solve for 'm': m = 24/4.m = 6.So, "the solution to the equation is m = 6".

Test Avg: 87
Final Exam: ?
If the teacher weights homework at 20%, Quizzes at 20%
Tests at 40% , and the final exam at 20%, what is the
minimum grade Anna can make on the final so that she
scores a 90 in the class?
a. 86
b. 91
C.
d
94
98
Answer:
b) 91
Step-by-step explanation:
Step 1: Multiple marks by its weights
Homework average: 95 x 20% = 19
Quiz average: 90 x 20% = 18
Test average: 87 x 40% = 34.8
Final exam: y x 20% = 0.2y
Step 2: Add all weighted averages and find y
19+18+34.8+0.2y = 90
71.8 + 0.2y = 90
y = 18.2/0.2
y = 91
Therefore, Anna needs to score minimum 91 in the final exam so that she can score a 90 in class.

Charmaine will run less than 26 miles this week. So far, she has run 18 miles. What are the possible numbers of additional miles she will run? Use t for the number of additional miles she will run. Write your answer as an inequality solved for t
Answer:
18+t<26
t={1,2,3,4,5,6,7}
Step-by-step explanation:
18+t<26
alright, so you know that she will run less than 26. That means she cannot run 26 or 27 or any more miles than that.
She can run 19, 20, 21, 22, 23, 24, or 25 miles in total from her starting point which is 18.
She already ran 18 miles. If she ran one more it would be 19, if she ran 2 more it could be 20. But she CAN NOT pass 25 miles. (it is not less than OR equal to)
so let me put it like this:
18+1<26 yes because 18+1=19 which is less than 26
18+2<26 yes because 18+2=20 which is less than 26
18+3<26 yes because 18+3=21 which is less than 26
18+4<26 yes because 18+4=22 which is less than 26
18+5<26 yes because 18+5=23 which is less than 26
18+6<26 yes because 18+6=24 which is less than 26
18+7<26 yes because 18+7=25 which is less than 26
18+8<26 NOOO because 18+8=26 which is NOT less than 26 (it's equal, not less than)

The sides of a triangle are a + 3 ¼, 2a, and 7 ½ - a. If a = 4 1/8, what is the length of each of the three sides? Also, find the perimeter of the triangle showing steps for your work.
Answer: Side one is 7 3/8
Side two is 8 2/8
Side three is 3 3/8
Perimeter is 19
Step-by-step explanation:
The first side is a+3 1/4
the second side is 2a
The third side is 7 1/2-a
Plug 4 1/8 in for a
First side 4 1/8+3 1/4
Find the common denomnator which is 8
4 1/8+3 2/8
7 3/8
First side is 7 3/8
Second side 2(4 1/8)=4 1/8 +4 1/8= 8 2/8
Third side is 7 1/2-4 1/8
Find the common denominator which is 8
7 4/8-4 1/8= 3 3/8
Third side is 3 3/8
The perimeter is adding all the three sides together
7 3/8+8 2/8+ 3 3/8=18 8/8
Reduce 18 8/8=18 +1=19
Answer:
Perimeter = 19 units
Step-by-step explanation:
Given a = 4 1/8
[tex]Side1 = a + 3\frac{1}{4}\\Side2 = 2a\\Side3 = 7\frac{1}{2}-a[/tex]
The next step is substituting the a value in the expressions:
[tex]Side1 = 4\frac{1}{8}+ 3\frac{1}{4}\\Side2 = 2*(4\frac{1}{8})\\Side3 = 7\frac{1}{2}-4\frac{1}{8}[/tex]
Then, fractions with different denominators must be converted to the same denominator. Also, the multiplication of a whole number by a mixed number can be done by using distributive law:
[tex]Side1 = 4\frac{1}{8}+ 3\frac{2}{8}\\Side2 = 8\frac{2}{8}\\Side3 = 7\frac{4}{8}-4\frac{1}{8}[/tex]
[tex]Side1 = 7\frac{3}{8}\\Side2 = 8\frac{1}{4}\\Side3 = 3\frac{3}{8}[/tex]
Now, the perimeter is the sum of all the sides. Therefore, the perimeter is:
[tex]Perimeter = 7\frac{3}{8} + 8\frac{1}{4} + 3\frac{3}{8}[/tex]
Which is 19 units.

Use the properties of exponents to complete the equivalent expression.
Answer:
15
Step-by-step explanation:
We can multiply powers with the same base
x^4⋅x^2=(x⋅x⋅x⋅x)⋅(x⋅x)=x^6
Properties of exponents are rules used to simplify mathematical expressions involving exponents. Examples are Power of a Power which means adding exponents when multiplying two expressions with the same base, and Quotient of Powers which is subtracting exponents when dividing two expressions with the same base.
Explanation:The question is about the properties of exponents. In mathematics, the properties of exponents refer to the rules that guide how expressions involving exponents are handled. For example, when you multiply two expressions with the same base, you add the exponents (also known as the Power of a Power property). So, an exponent like x^3 * x^2 simplifies to x^(3+2) = x^5.
Another example is the quotient of powers property, where you subtract the exponents when dividing two expressions with the same base. So, an expression like x^5 / x^3 simplifies to x^(5-3) = x^2.
These are just a couple of the basic properties of exponents. Other properties include the power of a product, the power of a quotient, zero exponent, and negative exponent. Each of these properties follows specific rules to simplify the expression involving exponents.

Answer:
Step-by-step explanation:
The graph of y= -4×+7 is a straight line with slope -4 and y-intercept 7. Please do not use × to represent the independent variable; use x instead. × represents multiplication.
To graph this function, first plot the y-intercept, b, which is (0, 7).
Next, starting with your pencil point at (0, 7), move the point 1 unit to the right and plot another point (which will be (1, 7) ). Now move your pencil point 4 units down and plot your third point, which will be (1, 3).
Finally, draw a straight line thru the first and third points, that is, thru (0, 7) and (1, 3). Notice how this line has the slope -4 and the y-intercept (0, 7).
