Number 1 is 6 number two is -8 and number three is -10
Answer:
Step-by-step explanation:
1. Since, it is given that ABCD is a parallelogram, therefore opposite angles of parallelogram are equal, hence
∠B=∠D
⇒7x-31=5x+13
⇒2x=44
⇒x=22
Hence, option B is correct.
2. Since, we get x=22, therefore
∠B=7x-31=7(22)-31=154-31=123°
∠B=123°
and ∠D=5x+13=5(22)+13=123°
∠D=123°
Also, ∠A+∠D=180°(corresponding angles)
⇒∠A=180-123
⇒∠A=57°
Now, ∠A=∠C=57°(opposite angles of parallelogram)
thus, Two of the angles measure 57°, and the other two measure 123°.
Therefore, option A is correct.
D-7<span>≤ 3
add 7 to both sides
d</span><span>≤10</span>
Answer:
1a. 32 2/5 F
1b. 73 2/5 F
C=(F-32)×5/9
2.P=$340
Step-by-step explanation:
S(2)=s(1)+3
s(3)=2(s(2)) now they say that s(3)=38 then:
2(s(2))=38
s(2)=19, and from earlier s(2)=s(1)+3 we get:
s(1)+3=19
s(1)=16
So sales for the first year was 16 million dollars.
