The inequality that describes the calories burned is 7x + 9y ≥ 441
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
let x represent the number of minutes of running and y represent the number of minutes of swimming, hence:
7x + 9y ≥ 441
The inequality that describes the calories burned is 7x + 9y ≥ 441

Answer:
D=1/2
Step-by-step explanation:
72d-45+13=12d-2
60d-45+13=-2
60d+13=43
60d=30
d=1/2
Reflection across the line y= -x,
(x, y) —-> (-y, -x)
so, C’ will be (-1, 3), B’ will be (3, 2), and A’ will be (2, -6)
The length of one segment is 15 cm and other segment is 60 cm
Step-by-step explanation:
Let x be the length of one segment and y be the length of other segment
Then according to given statement
x+y=75 Eqn 1
And
one the segments are four times the other
x=4y Eqn 2
Hence,
The length of one segment is 15 cm and other segment is 60 cm

Answer:
$3.0375
Step-by-step explanation:
Original price of dinner = $2.25
If cost percentage of 35%, then the additional cost paid will be;
35% * 2.25
= 0.35 * 2.25
= $0.7875
Target price = Original price + additional cost
Target price = $2.25 + $0.7875
Target price = $3.0375
