Meg is 6 years older than Victor. Meg's age is 2 years less than five times Victor's age. The equations below model the relation

ship between Meg's age (m) and Victor's age (v):
m = v + 6
m = 5v − 2

Which is a possible correct method to find Meg's and Victor's ages?

A) Solve m + 6 = 5m − 2 to find the value of m.
B) Write the points where the graphs of the equations intersect the x axis.
C) Solve v + 6 = 5v − 2 to find the value of v.
D) Write the points where the graphs of the equations intersect the y axis.

Let's see our options
A. this is wrong, m and v have been switched
B. this is assuming that one of their ages is 0
C. correct, v+6=m=5v-2, or v+6=5v-2
D. this assumes the other person is 0 years old

Answer:  The correct option is

(C) Solve v + 6 = 5v − 2 to find the value of v.

Step-by-step explanation:  Given that Meg is 6 years older than Victor. Meg's age is 2 years less than five times Victor's age.

The following equations model the relationship between Meg's age (m) and Victor's age (v):

m = v + 6

m = 5v − 2

We are to select the possible correct method to find Meg's and Victor's age.

Since both the equations gives the value of m, so it is better to compare both the equations to solve the given system.

That is,

after comparing both the equations, we will get

v + 6 = 5v - 2.

From here, we get the value of v and then substituting this value in any one of the two equations, we will readily find the value of m.

Thus, option (C) is CORRECT.

five years ago Kate's age was four less than twice the Mary's age. If mary is 11 now, how old is kate now?
Natali [406]

Answer:

13 years old

Step-by-step explanation:

2x - 4

11-5=6

6 x 2 = 12

12 - 4 = 8

8 + 5 = 13

CHECKING JUST TO MAKE SURE:

13 - 5 = 8

11 - 5 = 6

6 x 2 = 12

12 - 8 = 4

You can now tell that it is correct.

It takes a turtle 3 1/4 hours to walk 1 1/2 miles how many hours does it take to walk one mile (show the work please)​
Sliva [168]

Answer:

2  1/6 hours.

Step-by-step explanation:

It walks 1 1/2 miles  in 3 1/4 hours.

So it walks 1 mile in (3 1/4 ) /  (1 1/2) hours.

= 13/4 / 3/2

= 13/4 * 2/3

= 26/12 hours

=  2  1/6 hours.

The polygons below are similar. Find the scale factor of the SMALLER figure to the LARGER.
abruzzese [7]

Answer:

A. 5:6

Step-by-step explanation:

The scale factor of the smaller figure to the larger = the ratio of a side of the smaller figure to the corresponding side of the larger figure.

Thus, side length of 25 units of the smaller figure corresponds to the side length of 30 units.

Therefore:

Scale factor = 25:30

Simplify

Scale factor of the smaller figure to the larger = 5:6

A student identification card consists
denis23 [38]

Answer:

\frac{1}{30240}

Step-by-step explanation:

Given

ID Card of 5 digits

Possibly Digits = {0,1...,9}

Required

Probability that a card has exact number 94213

First, we have o determine the total possible number of ID card numbers

Let the card number be represented by ABCDE

Given that repetition of digits is not allowed;

<em>A can be any of 10 digits</em>

<em>B can any of the remaining 9 digits</em>

<em>C can be any of the remaining 8 digits</em>

<em>D can be any of the remaining 7 digits</em>

<em>E can be any of the remaining 6 digits</em>

<em />

Total number of cards = 10 * 9 *8 * 7 * 6

Total = 30240

Provided that the card number is generated at random; each card number has the same probability of \frac{1}{30240}

Hence, the probability of having 94213 is \frac{1}{30240}
