Step-by-step explanation:
Hello There!
The angle labeled 6x is a right angle
If an angle is formed using the diameter of a circle then the opposite angle of that side is a right angle
So 6x = 90
isolate the variable
divide each side by 6
90/6= 15
6x/6=x
we're left with x = 15
Answer:
Step-by-step explanation:
6x5 is 30
3 x 4 - 1 + 2
With parentheses would be - (3x4) - (1+2)
This is because either way, you would still do the multiplication first because of the rule of PEMDAS/GEMDAS which states that parentheses and grouping symbols go first.
1) 50 - 25 = 25 <<< difference and whole.
2) 25 × 100 = 2500
3) 2500 ÷ 25 = 100%
Final Answer: 100% is the percent increased not change
Also have a NICE DAY!!!! :) : D
Distribute.
8(y+4)
8y+32= 7y+38
Subtract 32.
8y= 7y+6
Subtract 7y from both sides.
1y= 6
Divide 1 into both sides.
y=6
I hope this helped!
