Answer:
1: n > -75
2: n < -12
Step-by-step explanation:
1: n/-3 - 8 < 17
n/-3 (- 8 + 8) < 17 + 8
n/-3 < 25
n/-3(-3) < 25(-3)
n < -75
n > -75 (switch symbol when you divide or multiply by a negative number)
2: n/-2 + 11 > 17
n/-2 (+ 11 - 11) > 17 - 11
n/-2 > 6
n/-2(-2) > 6(-2)
n > -12
n < -12 (switch symbol when you divide or multiply by a negative number)
Answer: $32
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
Answer:
x= 2.73cm
<u>1cm : 0.6828 = 4cm : 2.73cm</u>
For the same angle we just work out 1cm first.
a^2+ b^2= c^2
0.82^2 + b^2 = 1^2 = changing to units 10
6.724 + b^2 = 10
10-6.724 = 2.276
Then x 3 and change units down by 10= 0.6828
Step-by-step explanation:
Below shows why we must convert to mm from cm
a^2+ b^2= c^2
0.82^2 + b^2 = 1^2 =
0.6724 + b^2 = 1
1 - 0.6724 = b = 0.2276
0.2276 x 3 = 0.6828 cm
