Answer:
3.5 min
Step-by-step explanation:
13. 80 + 60 - 140. 180 - 140 = 40 degrees.
14. 90 + 160 + 85 = 275. 360 - 275 = 85 degrees.
16. 105 + 60 + 120 + 115 = 400. 450 - 400 = 50 degrees.
17. 180 - 110 -70 / 2 = 35. 180 - 35 = 145 degrees.
Hope this helps.
The value of x is option C) x=8.6
<u>Step-by-step explanation</u>:
Given that,
- The triangle ABC is similar to triangle DEC.
- It means that the side AB of triangle ABC is in proportion to side DE of triangle DEC.
⇒ AB/DE
⇒ 11/7.
Also, the side AD of triangle ABC is in proportion to side DC of triangle DEC.
⇒ AD/DC
⇒ (x+15)/15.
<u>To find the value of x :</u>
Equating the two proportions AB/DE and AD/DC.
11/7 = (x+15)/15
Keep x term alone on one side,
x+15 = 15(11/7)
x = (165/7) - 15
x = 23.6 - 15
x = 8.6
Step-by-step explanation:
y=2x-5 is in y=mx+b
Where m = slope
To find y-intercept :
Let x =0
Answer:
if there was a 15% discount, then you paid 75% of the original price. Since we don't know the orginal price, we will assign it the variable x. Change 75% to a decimal. The equation would be:
.75x = 208.25 To get the variable by itself, divide each side by .75
.75x/.75= 208.25/.75
x = 277.6
The original price of the suit was $277.6
I hope this helped you.
