Answer: x = 40
Step-by-step explanation:
these two angles are vertical angles, they will equal each other
therefore, move numbers and variables to the opposite sides of the = sign to isolate the X
3x-10 = 2x + 30
+10 +10 move the -10 by doing opposite
_____________
3x = 2x + 40
-2x -2x move -2x by doing opposite
____________
x = 40
you can check your work by substituting 40 in place of x
3(40) - 10 = 2(40) +30
120-10 = 80 + 30
110 = 110
answer is correct
Answer:
x=$10
y=$12
Step-by-step explanation:
Step one:
given
let senior tickets be x
and child be y
8x+9y=188----1
also on the second day
x+5y=70-------2
the system of equation is
8x+9y=188-----1
x+5y=70---------2
x=70-5y, put this in 1
8(70-5y)+9y=188
560-40y+9y=188
-31y=-372
divide by -31
y=-372/-31
y=$12
put y= 12 in x+5y=70---------2
x+5(12)=70---------2
x+60=70
x=$10

Answer:
option B
Elia multiply the dividend by 100 instead of 10.
Step-by-step explanation:
Given that,
divisor = 0.6
dividend = 1.848
Elia decided to multiply each by 10 to get
<h3>divisor = 0.6 x 10 = 6</h3><h3 /><h3>dividend = 1.848 x 10 = 18.48</h3>
but unfortunately she multiply the dividend by 100
As,
1.848 x 100 = 184.8
So,
Elia's error was that she multiply the dividend by 100 instead of 10.
