Answer:
2) d= -3
5) f= -44
Step-by-step explanation:
You're welcome :)
7x+3(4x-8)=109
7x+12x-24=109
19x-24=109
19x=109+24
19x=133
X=133÷19
X=7

about $3 because...

and

which is probably as close as your gonna get
Answer:
Step-by-step explanation:
<u><em>Q 4.</em></u> (25m + 25m) ÷ 25 sec. = <em>2 m/sec.</em>
<u><em>Q 5.</em></u> This question belongs to Physics and not Mathematics!!!
Wavelength (lambda) = Velocity (v) ÷ Frequency (
or Hz )
f = v / (lambda)
f = 3 / 2 = <em>1.5 (Hz)</em>
<u><em>Q 6.</em></u> 0.060 ÷ 2 = <em>0.030 m</em>
Answer: the number -5 is a real number
