solve 28m+21=413 thanks!
Answer:
14
Step-by-step explanation:
28m + 21 = 413
28m = 413 - 21
= 392
m = 392/28
= 14
Therefore m is 14 :)
Answer:
14
Step-by-step explanation:
28m+21=413
Subtract both sides by 21
28m=413-21
28m=392
m=14

The simplified form of the given exponent is 27.
What is the exponent?Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.
The given expression is 2+5²
Here, 2+25
= 27
Now, 0²=0×0
= 0

A gallon of gasoline cost $3.00 last year, and now costs 5% more. What is the cost of a gallon of gasoline now?
a) 4.50
b) 3.15
c) 3.05
Answer:
B
Step-by-step explanation:
We know that Last year one gallon costs $3.00
and we also know that it costs %5 more this year.
We know that %100 is always the same which is $3.00
Then since we know $3.00 is %100, we can add %5 to %100 to get %105.
Then you multiply 105/100 by 3 then you will get 3.15 which is what B is
So that means our answer is B

Write an inequality to
represent “a number is at
most two”
Answer:
x > 2
Step-by-step explanation:
The required inequality to represent “a number is at most two” is x ≤ 2.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
The expression of a number is at most two, implying that a number cannot be more than 2.
So the inequality that best represents the scenario is given as x ≤ 2.
Thus, the required inequality to represent “a number is at most two” is x ≤ 2.

Juan needs to simplify the fraction LaTeX: \frac{32}{52}32 52. He will need to divide the numerator and the denominator by the greatest common factor. What is the greatest common factor of 32 and 52?
Answer:
4Step-by-step explanation:
Given the expression, 32/52
Juan need to divide the numerator and the denominator by the greatest common factor
For 32;
32 = 8 * 4
For 53
52 = 13 * 4
Find the ratio
32/52 = (8*4)/(13*4)
32/52 = 8/13
Since 4 is common to both factors, Hence the greatest common factor is 4

David wants to buy a new tablet computer. He looks at a sales ad and sees that a computer store is selling a tablet computer for $499 which is 1/3 off the regular price.
Part A:
Write an equation that represents the situation. Let x = the original cost of the tablet.
Part B:
Find the original cost of the tablet computer.
Answer:
Part A: x÷3=$499
Part B: $1497
Step-by-step explanation:
A: Because to find a fraction of somthing we have to divide, so in this case we divided the original price by 3 to get $499.
B:To find the original price we have to multiply the one third of it ($499) by 3 to get the original amount.

Answer:
One way of awarding interest is called simple interest. Before we provide the formula used in calculating simple interest, let’s first define some basic terms.
Balance. The balance is the current amount in an account or the current amount owed on a loan.
Principal. The principal is the initial amount invested or borrowed.
Rate. This is the interest rate, usually given as a percent per year.
Time. This is the time duration of the loan or investment. If the interest rate is per year, then the time must be measured in years.
To calculate the simple interest on an account or loan, use the following formula.
Simple Interest
Simple interest is calculated with the formula
I=Prt,
where I is the interest, P is the principal, r is the interest rate, and t is the time.

Mark drew a line to fit the data in a scatter plot as shown What is the equation of the line that Mark drew?
Answer:
Step-by-step explanation:y=1/4 X +6
Answer:
y= 1/4x+ 6
Step-by-step explanation:
Because the line intersects the y-axis at 6, we know the y-intercept, b, is 6.
By counting, we can see the line rises 1 unit for every 4 units it runs to the right. So, the slope, m, of the line is 1/4.
Substitute m and b into the slope-intercept equation, y = mx + b. The equation of the line is y = 1/4 x + 6.
