Two angles are vertical angles. The measure of one angle is (3x) degrees. The measure of the other angle is 42 degrees. What is the value of x?

Answers

Answer:

x =14

Step-by-step explanation:

Vertical angles are equal.

This means that 3x = 42

Divide each side by 3

3x/3 = 42/3

x =14

Answer: x=46.

Step-by-step explanation:

Vertical angles are opposite of one another. A whole line is 180 degrees. You have to subtract 42 from 180 which gives you 138. Then you divide by 3. Then you get 46.

So your hole must be deeper by another 2 feet and 6 inches. (or by 30 inches)

Step-by-step explanation:

1 foot = 12 in

4 feet = 12×4 in

4 ft = 48 in (how deep it should be)

Current depth: 1 foot + 6 in

1 ft = 12in

12in + 6in = 18in (the current depth of your hole)
48in (total) - 18in (current) = 30 in (remaining depth)

30 in = ?ft + ?in
1 foot = 12 in 2ft = 24in 3ft = 36in 4ft=48in

The closest number that is below 30 is 24
We have 24inch = 2ft
And we have 6 inches remaining (30in-24in=6in)

2ft + 6in or 30in remaining

Gary ran 6 more laps than Edwin during track practice. Together they ran 40 laps. Write a system of equations that represents this situation.

Answers

This can be represented using a system of equations. The first equation is Gary's total number of laps (letting G represent Gary's laps): G = 6 + Edmund's laps. The second equation is Edmund's total number of laps, letting E represent Edmund's laps: E + 6 = 40. Combining these two equations, we get G = E + 6 and E + 6 = 40, which becomes G = 40 - 6 and E = 40 - 6. Thus, the system of equations is G = 40 - 6 and E = 40 - 6.

Answer:

1. e + g = 40
2. g - 6 = e

Step-by-step explanation: Hello!

You know that Gary ran 6 more laps than Edwin during track practice. Let's represent Edwin as the variable (e) and Gary as the variable (g). You also know that together they ran 40 laps. Since g ran 6 more laps than e and they both ran 40 laps combined, the following system of equations can represent this situation.

e + g = 40
g - 6 = e or e + 6 = g

please help

Answers

Answer:

3/5

Given ratio 12 yard to 20 feet,

To simplify the ratio, we first need to find the common multiples of 12 and 20,

to find the common multiples of 12 and 20, we need to factorize 12 and 20.

On factorization, we get 12= 2*2*3 and 20=2*2*5.

Common multiples of 12 and 20 are that is 4.

And now simplifying the given ratio, 12 yard to 20 feet , that is 12/20=3/5

The slope of the graph is 1/4 rise/run and this is the gradient (m) of the graph. Because the gradient/slope is positive it means it is increasing from left to right.

The equation of a line is y = mx + b

Where m is the gradient/slope in this case 1/4 and b is the y-intercept in this case zero.

Based on that information we substitute it into the formula y = mx + b to get
y = 1/4 x as the equation of the line.
