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.

~kites have adjacent sides equal~

x = 3x-12

move 3x to the other side as a negative number

-2x = -12

divide both sides by -2

-12 divided by -2 is 6

so, x is equal to 6

but, we aren't done yet because the questions asks for the value of angle b

substitute the value we found into the equation for angle b

3(6)-12

36-12

24

so, angle b has a value of 24 degrees

Determine the equation of the circle graphed below.
Wittaler [7]

Answer:

(x - 6)^2 + (y + 4)^2 = 4

Step-by-step explanation:

formula for a circle

( x - h )^2 + ( y - k )^2 = r^2

(h,k) is the center

r is the radius

(6,-4) is center

2 is radius

Substitute in numbers and watch the negatives.

The ratio of Dina’s bathing suits to Yana’s bathing suits was 4:1. if Dina has 24 more bathing suits than Yana, how many bathing
lina2011 [118]

Answer:  Yana has 8 bathing suits.

Step-by-step explanation:  Given that the ratio of Dina’s bathing suits to Yana’s bathing suits was 4 : 1 and Dina has 24 more bathing suits than Yana.

We are to find the number of bathing suits that Yana has.

Let 4x and x represents the number of bathing suits that Dina and Yana have respectively.

Then, according to the given information, we have

4x-x=24\\\\\Rightarrow 3x=24\\\\\Rightarrow x=\dfrac{24}{3}\\\\\Rightarrow x=8.

Therefore, the number of bathing suits that Yana has is given by

x=8.

Thus, Yana has 8 bathing suits.
