Answer:
Step-by-step explanation:
#1 side kl
#2 side fg
Take the 30 and divide it by 100 and you get the percent.
Ex. 30/100 = .3
Then multiply 64 by the percent.
64 x .3 = 19.20
Answer:
y = 4/5x - 3
Step-by-step explanation:
The slope-intercept form of a line is y = mx + b. We need to isolate the y.
(add 4x to 15)
-4x + 5y = 15
5y = 4x + 15
(divide by 5 from both sides)
y = 4/5x + 15/5
y = 4/5x + 3
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.
The slope of n should be Undefined
