Answer:

x=2 and y= -1

Step-by-step explanation:

substitute x value in equation 2

2(5y+7)+4y=0

10y+14+4y=0

14y = -14

y= -1

here,

x= 5(-1)+7

x= -5+7

x=2

What is the radian measure of the smallest angle formed by the hands of a clock at 7 o'clock?
netineya [11]
See the picture attached to better understand the problem
we know that
a full circle is a 360 degrees
divided in 12 equals parts-------> 360/12-------> 30 degrees each part

<span>the smallest angle formed by the hands of a clock at 7 o'clock has 5 parts
so
5*30</span>°------> 150°

convert to radian
pi radians---------> 180°
 x ---------------> 150°
x=150*pi/180--------> x=0.83*pi radians

the answer is
0.83*pi radians  or 2.62 radians

What is the solution for the equation 3x + 0.3 = 3.3.
hoa [83]

Answer:

3x+0.3=3.3.

                               \            /    

                   We move all terms to the left:

                              3x+0.3-(3.3.)=0

        We add all the numbers together, and all the variables

                              3x+0.3-0=0

        We add all the numbers together, and all the variables

                              3x+0.3=0

     We move all terms containing x to the left, all other terms to the right

                               3x=-0.3

                                x=-0.3/3

                               x=-0.3/3

                               /             \
