Answer:
The mother is 3d older than the daughter
Step-by-step explanation:
Given
Represent the mother's age with m
and
The daughter's age with d
Required
Determine how much older is the mother
First, we need to calculate the mother's age
[tex]m = 4 * d[/tex]
[tex]m = 4d[/tex]
Next, we calculate their age difference
[tex]Age\ Difference = m - d[/tex]
Substitute 4d for m, we have:
[tex]Age\ Difference = 4d - d[/tex]
[tex]Age\ Difference = 3d[/tex]
Hence, the mother is 3d older than the daughter

Answer choices:
A. n, n+2, n+4
B. n, n+1, n+2
C. n, n+1, n+3
D. n+1, n+2, n+3
The sum of 3 consecutive odd natural nos. can be represented by n + ( n+2 ) + (n + 4 ).
What are consecutive nos. ?Consecutive nos. are every no. after each other.
According to the given question we have to represent the sum of 3 consecutive odd natural nos.
We know that consecutive odd natural nos. come after every two digits.
∴ Assuming the first odd natural no. to be n.
So, Next odd natural no. will be (n + 2) and the third consecutive odd natural no. will be (n + 2) + 2 which is = (n + 4).
∴ The sum of 3 consecutive natural numbers can be represented by
n + (n + 2) + (n+4).

Suppose that a bike rents for 50php plus 8php per hour. Write an equation in slope-intercept form that models this situation.
Answer: C(x) = (8 php)*x + 50 php.
Step-by-step explanation:
In a linear equation:
y = a*x + b
a is the slope.
x is the variable
b is the y-intercept.
In this case, we have
The rent is 50 php fixed, plus 8 php per hour.
Then we will pay the 50php only one time, and it does not depend on the number of hours that we rent, then this is the y-intercept.
then if we rent the bike for x hours, we will pay a plus of x*8 php.
Then the total cost for x hours, C(x), will be
C(x) = (8 php)*x + 50 php.
Then the slope is 8 php, and the y-intercept is 50 php.

The measures of angles 1, 2 and 3 are, 33, 90, 57 degree.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
from the given diagram,
angle 3 = 57deg (alt. angles, //lines)
angle 2 = 180 - 57 - 33 = 90deg (angles in a triangle)
angle 1 = 180 - 90 - 57 = 33 deg (angles on a str line are supplementary)
