Answer:

x = 20

Step-by-step explanation:

These angles are equal to each other because they are vertical angles.

Hence, we can equal the two measurements together to solve for x:

3x + 50 = 6x - 10

3x + 60 = 6x

60 = 3x

20 = x

Check your work:

3(20) + 50 = 6(20) - 10

60 + 50 = 120 - 10

110 = 110

Correct

When the three integers 400, 366, and 213 are divided by a positive integer d > 1, the remainders are the same. What is the l

raketka [301]

The number d is not a divisor of the integers 400, 366 and 213

The least possible value of d is 17

<h3>How to determine the least possible value of d</h3>

The numbers are given as:

400, 366 and 213

The divisor is given as: d

Where d > 1

To determine the least possible value of d, we make use of the following Python program, where comments are used to explain each action.

#This iterates from 2 to the smallest number of the three divisors

for d in range(2,213):

#This checks for the common remainder

if(400%d == 366%d) and (400%d == 213%d):

#This prints the value of d, when the smallest remainder of all three integers is determined

print(d)

At the end of the program, the output is 17

Hence, the least possible value of d is 17

the printed matter on a 14 by 18 centimeter page of a book must covor 140 square centimeters. if all margins are to be the same

luda_lava [24]

Let
x----------------> width of the margin
we know that

[Area printed matter]=140
[Area printed matter]=[(14-2x)*(18-2x)]
then
[(14-2x)*(18-2x)]=140--------> (252-28x-36x+4x²)=140
(252-64x+4x²)=140----------> 4x²-64x+112=0

using a graph tool---------> I solve the quadratic equation
see the attached figure
x1=2
x2=14----------> is not solution

the answer is
the margin should be 2 cm
