3) adjacent
x = 180 - 34 = 146
4)adjacent
x = 90 - 74 = 16
6)supplementary
2x + 5 + 75 = 180
2x + 80 = 180
2x = 100
x = 50
Cross multiply...
Thus,
x(x+4)=(x+12)(x+8)
expand...
x^2+4x=x^2+8x+12x+96
Simply both sides of the equation.
x^2+4x=x^2+20x+96
simply further by adding ask like terms...
-16x=96
Solve for x by making x the subject.
therefore
x=-6.
Ok so
t=number of text messsages
p=number of picture messages
total number is 33
t+p=33
if text is 0.18 per pic and picture is 0.45 per text
total cost is 8.3
0.18t+0.45p=8.3
times 100 both sides for ease
18t+45p=830
we now have 2 equations
t+p=33
18t+45p=830
multiply first equation by -18 and add to second equation
18t+45p=830
<span>-18t-18p=-594 +</span>
0t+27p=236
27p=236
divide both sides by 27
p=8.740740740740744
this is impossible becasue you can't send 0.740740740740744 of a message so you did a mistype somewhere
Answer:
salmon per pound is $16.68
shrimp per pound is $6.71
Step-by-step explanation:
166.63/10=16.68
16.68*5=83.04
143.86 -83.04=60.46
60.46/9 = 6.71
Fifty times two plus fifteen plus two
