Jaxon has $65 in his savings account. He deposits $15 every week. His father also deposits $25 into the account every time Jaxon
HACTEHA [7]
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.

Without calculating, how do you know that the equation | 4x-7 | = -1 has no solution ?
Hatshy [7]
Hello

By just looking at the question, you should know that if there an absolute value symbol (which are those two straight lines surrounding that equation), the answer will always be positive.

CAN SOMEONE PLSSSSS ANSWER BOTH OF THESE QUESTIONS<br> I WILL MARK BRAINLIEST
Margaret [11]

Answer: B and C

Step-by-step explanation:

404 + 50 + 50 = 504

you are buying  144 magazines total

504/144 = cost of one magazine

cost of one = 3.50

you are paying $60 a year for 12 years

60 x 12 = 720

720/144 = 5

5 - 3.50 = 1.50

2.

120x + 180x = 1080

300x = 1080

x = 1080/300

x = 3.6

3.6 x 60 = 216
