Answer:

The answer is 27 miles in the morning and 85 miles in the afternoon.

Step-by-step explanation:

So first you have to set up an equation.

X represents: the number of miles they rode in the morning.

3X + 4 represents: 4 more than 3 times this many in the afternoon

3X+4 + X = 112 represents: adding the morning miles and the afternoon miles together to get the total trip of 112 miles

Your equation to solve 3X+4+X =112

Now you can solve the equation

3X+4+X =112

Combine like terms (x's)

3X + X = 4X

4X+4=112

Subtract 4 from each side:

4X+ 4 - 4= 112-4

4-4 = 0 and 112-4 = 108

4X = 108

Divide both sides by 4

4X/4 = 108/4

4/4 = 1X and 104/4 = 27

X = 27

Remember X represents the number of miles they rode in the morning, so they rode 27 miles in the morning.

Remember 3X+4 represents the number of miles they rode in the afternoon.

3X+4 =

3(27)+4 =

81+4 =

85 miles.

That means in the afternoon, they rode 85 Miles

If ⅙ of a roll of wallpaper covers ¼ of the wall. How many rolls of paper are needed to cover 4 walls?

AVprozaik [17]

Answer:

if 1/6 of a roll of paper covers 1/4 of a wall, this means that we will need 4/6 of a roll to cover a whole wall, now the question is asking how many rolls will we need to cover 4 walls, we already know that it takes 4/6 to fill one wall so if we add 4/6+4/6+4/6+4/6 we will get 16/6 or 2 4/6

we will need 16/6 or 2 4/6 of rolls of paper to cover 4 walls

Find the value of y.

olga nikolaevna [1]

Try this option:
1. the sides of the biggest triangle are 16; x and √(16²-x²); the sides of the smallest triange are x;5 and y. The smallest triangle ~ the biggest triangle. Using the property of the similar triangles:
$\frac{x}{5} = \frac{16}{x}, \ then \ x= \sqrt{80}$
2. according to the Pyphagorean theorem (in the smallest triangle):
$y= \sqrt{ \sqrt{80^2} -5^2} = \sqrt{55}$

answer: y=√55.

Indicate whether the statement is true of false.

yawa3891 [41]

The statement is false, as the system can have no solutions or infinite solutions.

<h3>Is the statement true or false?</h3>

The statement says that a system of linear equations with 3 variables and 3 equations has one solution.

If the variables are x, y, and z, then the system can be written as:

$a_1*x + b_1*y + c_1*z = d_1\\\\a_2*x + b_2*y + c_2*z = d_2\\\\a_3*x + b_3*y + c_3*z = d_3$
