We know that the angle above 10x + 54 must be 8x because of Alternate angles. And we also know that angles in a straight line add up to 180. So we can infer that 10x + 54 + 8x = 180
We can simplify that into 18x + 54 = 180
Now we take away 54 from both sides to get 18x = 126
Now divide both sides by 18 and we get
x = 7.
Now that we know that x = 7 we know that the 10x + 54 angle is equal to 124 by substituting the value of x in. We also know that 11y + 14 must equal to 124 because of vertically opposite angles. So we have 11y + 14 = 124.
Take away 14 from both sides; 11y = 110
Now divide both sides by 11 and we get
y = 10
So x = 7 and y = 10
I hope that you understood all of my steps and if this did help you a Brainliest would be very appreciated :)
Answer:
x=−48.541019
Step-by-step explanation:
4+√5x+66=x+10
Simplifies to:
2.236068x+70=x+10
Let's solve your equation step-by-step.
2.236068x+70=x+10
Step 1: Subtract x from both sides.
2.236068x+70−x=x+10−x
1.236068x+70=10
Step 2: Subtract 70 from both sides.
1.236068x+70−70=10−70
1.236068x=−60
Step 3: Divide both sides by 1.236068.
1.236068x
1.236068
=
−60
1.236068
x=−48.541019
Answer:
You are 48 inches
Step-by-step explanation:
You would just do the opposite of multiplication which is division so do 60/1.25 is 48 inches
It is different because to find out the answer, change all denominators to 10, since the LCD is 10.
6/10-5/10=1/10
6/10-6/10=0/10
1/10 is not equal to 0/10
