Step-by-step explanation:
Answer:
n=3.1
Step-by-step explanation:
Answer:
0.68
Step-by-step explanation:
10^-2 is 0.1 10 and go to the left 2
0.1 * 6.8 = 0.68
Y= 3 -x (1)
3x + 4y = 1 (2)
Substitute (1) for y in (2)
3x + 4(3 - x) = 1
Expand, simplify and then solve for x
3x + 12 - 4x = 1
3x - 4x = 1 -12
-x = -11
x = 11
Answer:
x = 71
Step-by-step explanation:
<B is a right angle, so triangle ABE is a right triangle, and angles BAE and AEB are complementary.
m<BAE + m<BEA = 90
42 + m<BEA = 90
m<BEA = 48
<BEC is a straight angle, so its measure is 180 deg.
m<CED + m<DEA + BEA = 180
61 + x + 48 = 180
x + 109 = 180
x = 71
