Answer:
C. x = 8 , y = 40
Step-by-step explanation:
since this is an Isosceles triangle 5x = 40° and x = 8
The sum of interior angles in a triangle is equal to 180°
40° + 5x + 2y + 20 = 180° add like terms
5x + 2y = 120
40 + 2y = 120 ➡ 2y = 80 and y = 40
Answer:
0.25*8+7=9
Step-by-step explanation:
8x+7=9
2/8=x
0.25=x
Answer:
x-120=899
Step-by-step explanation:
(x=1019)
Speed: 357 miles : 6.3 hours = 357 : 63/10 = 357 * 10/63 = 3570/63 = 56 42/63 mph
1. 5/8 + 1/8 = 6/8 --> 3/4
3. - 1/4+ 3/4:
-0.25+0.75= 0.5 OR 1/2
5. 5/9 + 5/9 = 10/9 --> 1 whole 1/9
7. 3/10 + 1/10 = 4/10 --> 2/5
9. 7/15 + 4/15 = 11/15
And I simplified them too :P
Also this is ez, to me :PP
