Given: The complex fraction is provided along with Esmerelda's steps in simplifying it. We aim to identify Esmerelda's errors. Solution: We begin by converting mixed fractions to improper fractions and using the reciprocal of the divisor. Consequently, the correct value of the given fraction is found. Three mistakes made by Esmerelda include: 1. Adding the numerators incorrectly. 2. Incorrectly adding the denominators. 3. Failing to apply the reciprocal of the divisor.

Leona [12049]

In this problem, the point-slope form of a line is defined as:

(y-y_ {0}) = m (x-x_ {0})

Where:

(x_ {0}, y_ {0}): represents a point on the line,

and m stands for the slope.

Given the details:

(x_ {0}, y_ {0}): (-2,4)\\m = \frac {2} {5}

Substitute the values:

y-4 = \frac {2} {5} (x - (- 2))\\y-4 = \frac {2} {5} (x + 2)

Thus, the equation of the line is:

y-4 = \frac {2} {5} (x + 2)

Answer:

y-4 = \frac {2} {5} (x + 2)

The gravity on the surface of the moon is 0.17 of the surface gravity on Earth. If Jack weighs 156 pounds on Earth, what would b
tester [11849]

Response:

Jack's weight on the moon will be 26.52 pounds

Step-by-step explanation:

x = 156 (Weight on Earth)

y = 0.17 (Moon's gravity)

z = Your weight on the moon

x * y = z

156 * 0.17 = 26.52

Jack will weigh 26.52 pounds.

The volume of the rectangular prism is 32 cubic feet more than the volume of the right triangular prism. Find the volume of each
tester [11849]

Answer:

Step-by-step explanation:

Denote the rectangular prism's volume as VR and the volume of the right triangular prism as VT. Given that the rectangular prism's volume exceeds that of the triangular prism by 32 cubic feet, we establish that VR = 32 + VT.

Calculating VR: VR = length * width * height = 6*x*3.

This simplifies to VR = 18x ft³.

For the triangular prism, VT can be calculated as Length * width * Height / 2, yielding VT = (7 * x * 4) / 2.

Thus, VT = 28x / 2, which simplifies to VT = 14x ft³.

Equating VR to 32 + VT allows the substitution: 18x = 32 + (14x).

Now, simplify the equation:

Combine like terms: 18x - 14x = 32.

This results in 4x = 32.

Dividing both sides by 4:

x = 8.

The volume for the rectangular prism comes to 18x, which equals 18*8.

The volume of the rectangular prism calculates to 144 ft³.

The volume for the right triangular prism calculates to 14x, which equals 14*8.

The volume of the right triangular prism calculates to 112 ft³.
