We basically have to cancel values on both sides until they are both on common ground.
7 + 3x = 5x + 13
-7 from both sides...
3x = 5x + 6
-5x from both sides...
-2x = 6
/-2 from both sides...
x = -3
Hope this helps!
Answer:
4:6
Step-by-step explanation:
because 2 is common factor of 8 and 12 so 8 divided by 2 equal 4 and 12 divided by 2 equals 6
Answer:
3/2 is the slope and (0,5) is the y-intercept
Step-by-step explanation:
We need slope-intercept form for this question, so we simplify the equation into:
-2y=-10-3x which is just
y=5+3/2x =
y=3/2x+5
When we compare this to y=mx+b, we see that 3/2 is the slope and (0,5) is the y-intercept.
Answer: 41%
Step-by-step explanation:
15 girls prefer biology.
Find the boys who prefer biology;
There are 36 girls in total so;
= 100 - 36
= 64 boys interviewed
14 boys prefer Physics
= 64 - 14
= 50 boys prefer Biology and Chemistry
7 out of the 31 who prefer chemistry are girls so the boys who prefer chemistry are;
= 31 - 7
= 24 boys
Boys who prefer Biology;
= 50 - 24
= 26 boys
Total who prefer biology;
= 15 girls + 26 boys
= 41 students
Percentage = 41/100 = 41%
