Answer:
Step-by-step explanation:
Answer:
<XYZ = 117°
<XYW+ WYZ = 117°
(6x+44)+(-10x+65)= 117°
6x+44-10x+65= 117°
-4x+ 109= 117°
-4x= 117-109
-4x= 8
x= 8/-4
x= -2
<XYW= 6x+44= 6×-2+44= -12+44= 32°
<WYZ= -10x+65 = -10×-2+ 65= 20+65= 85°
Step-by-step explanation:
The slide costs $2 each time you ride. $15/2 = 7.5 so you can ride it 7 times.
Answer:
a) 11.75 * 10^6
b) 1.35 * 10^-7
Step-by-step explanation:
Here, we want to find the sum and the difference
a) That would be;
(3.48 + 8.27) * 10^6
= 11.75 * 10^6
b) That would be;
(9.58-8.23) * 10^-7 = 1.35 * 10^-7
