Jaxon has $65 in his savings account. He deposits $15 every week. His father also deposits $25 into the account every time Jaxon

mows the lawn. His savings account balance can be shown with the following expression: 65 + 15w + 25m
Part A: Identify a coefficient, a variable, and a constant in this expression. (3 points)

Part B: If Jaxon saves for 20 weeks and mows the lawn 3 times, how much will he have in his account? Show your work to receive full credit. (4 points)

Part C: If Jaxon had $75 in his savings account, would the coefficient, variable, or constant in the expression change? Why? (3 points)

Part A:
<span>In the expression given, 65 + 15w + 25m: 65 = constant; 15 and 25 = coefficients; w and m = variables.</span>  
Thus, to define:
Constant is a number which the value is already fixed.
Variable is the unknown value in the algebraic expression.
Coefficient is a number which is placed before a variable that indicates how many times the variable is to be multiplied.

65 + 15w + 25m 
65 = 15 (1) + 25 (2)

Part B:
Let x be the savings account balance
W = # of weeks
M = frequency of mowing the lawn  

First, let’s use the expression given above: 15w + 25m.
Since we are solving for a constant, only the variables and coefficient of the expression given are to be used.  
Then, we substitute the variables’ corresponding values.
X = 15 (20) + 25 (3)
Therefore, the savings deposits will amount to:
X = 300 + 75 X = $375  

Part C:
$75 + w + 3m  
Constant will be $75.
Variables: w = no weekly deposit, m = 3
Coefficients: w = 1, m = remains at 25  

This is because we need to adjust the variables and coefficients to solve for the constant.

Leah claims that these figures are not similar. When she compared the heights, she wrote 27. Then she compared the bases and got
Flauer [41]

Answer:

<h2>Leah is actually wrong, because those rectangles are similar.</h2>

Step-by-step explanation:

Remember that similarity is about having proportional sides and congruent angles. When we have congruent sides, then those rectangles are congruent not similar.

In this case, to find the similarity, Leah should compare bases and heights thorugh division, because the ratio between heights and the ratio between bases must be equal. So, let's divide.

\frac{21}{6}=3.5

\frac{7}{2}=3.5

As you can observe, both ratios are equal.

Therefore, those rectangles are congruent.

What is 18 divided by 0.2 and how?
kati45 [8]
0.2 is the same as 2/10

18/(2/10)

As you may have learned in school, when you divide a fraction, you flip the fraction in the denominator, and change it to multiplication

18/(2/10) becomes 18 x (10/2)

multiply normally

18 x 10 = 180

divide to find answer

180/2 = 90

90 is your answer

hope this helps

Remember, when you meet this problem, flip the second fraction, and change the division sign into multiplication. (always second, never first (if first is a fraction)).

If Lana deposits $500 into a savings account that gains simple interest at
Oksana_A [137]

Answer:

10 years

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 2%/100 = 0.02 per year,

then, solving our equation

t = 100 / ( 500 × 0.02 ) = 10

t = 10 years

The time required to

accumulate simple interest of $ 100.00

from a principal of $ 500.00

at an interest rate of 2% per year

is 10 years.
