Step-by-step explanation:

Distance = (Rate)(Time) So, Time = (Distance)/(Rate)

Time at slower speed = Time at faster speed + 3

36/x = 36/(x+6) + 3

Multiply the equation by the LCD, x(x+6) to obtain:

36(x+6) = 36x + 3x(x+6)

36x + 216 = 36x + 3x2 + 18x

3x2 + 18x - 216 = 0

x2 + 6x - 72 = 0

(x + 12)(x - 6) = 0

x = -12 or x = 6

Since x can't be negative, x = 6 mph

Eva is picking fruit at a farm. The fees are $5 for entry to the farm, $2.50 per pound of blueberries, and $2 per pound of apple

olasank [31]

Answer:

The required expression is: $y = 5 + 2.50b + 2a$

Step-by-step explanation:

Given

$Entry = \$5$

$Blueberry = \$2.50$

$Apple = \$2$

Required

Write an expression for this scenario

If 1 pound of blueberry cost $2.50

then b pounds = 2.50 * b

If 1 pound of apple cost $2

then a pounds = 2 * a

The required expression (y) is then calculated as

$y = Entry\ Fee + Blueberry = Apple$

$y = 5 + 2.50 * b + 2 * a$

$y = 5 + 2.50b + 2a$

Hence, the required expression is: $y = 5 + 2.50b + 2a$

The value of 5 in 3.5 times the value of the 5 in 15 is the sentence that compares correctly with the values.

<h3>What is arithmetic?</h3>

Mathematical arithmetic is the study of the properties of the standard operations on numbers, such as addition, subtraction, multiplication, division, exponentiation, and root extraction. One of the branches of mathematics, 1a, deals with the application of addition, subtraction, multiplication, and division to nonnegative real numbers, sometimes including transfinite cardinals.

Given Data

Here, 5 in 15.2 is 1/10 times to 3.5.

The 5 in 3.5 is therefore $\frac{1}{10}$ times the 5 in 15.2, and likewise.

The value of 5 in 3.5 times the value of the 5 in 15 is the sentence that compares correctly with the values.
