1) p=# of paper clips, (p+5)/4   2) w=wages, 3w+18   3) a=# of apples, (a-8)/5=32   1 and 3 are a little ambiguous; they can be interpreted in other ways. I'll leave them as they are unless you have any questions.     I would have...

distance=rate*time d=rt 1/6=r*(1/12) multiply both sides by 12 12(1/6)=r*(1/12)12 2=r*1 2=r rate=2 miles per hour

A tower... (answer)

the tower, the wire, and the ground make a right triangle the tower and the ground are the legs, and the wire is the hypotenuse 5142=x2+1252 where x is the height of the tower 264,196=x2+15,625 x2=264,196-15,625 x2=248,571 x=√248,571 x=498.5689 feet however,...

form a right triangle with the vertical leg being 3300 and the horizontal leg being 3*5280=15,840 find the tangent of the angle which is the opposite over the adjacent tan(?)=3300/15,840 tan(?)=0.2083333 now use your calculator, the table in your book, or an online arctan calculator...

2*\$16.99=\$33.98 20% off 20%*\$33.98=0.2*\$33.98=\$6.796=\$6.80 off \$33.98-\$6.80=\$27.18, the price of the CDs after the discount another  way of solving this... if there is a 20% discount that means that Maria pays only 80% of the \$33.98(100%-20%=80%) 80%*\$33.98=0.8*\$33.98=\$27...

Here are some other answers using each digit individually. 20=(2/.1)(4^0) 13=(4!)/2+1^0 11=(2/.1)/√4+0! 10=(2/.1)/√4+0

(-2 3/4)*(4/5) change the mixed number into an improper fraction 2 3/4=(2*4+3)/4 2 3/4=11/4 -2 3/4=-11/4 now you have two fractions to multiply together the answer will be negative because a negative times a positive is negative (11/4)*(4/5)=(11*4)/(4*5)=44/20=2 4/20=2...

the distance around a circle is its circumference circumference=pi*diameter pi is an irrational number and let the diameter be a rational number an irrational number times a rational number gives you an irrational number you may think it's a rational number because you use a rational...

distance=rate*time d=rt 1=4t 1/4=4t/4 1/4=t t=1/4 hour or 15 minutes

inequalities (answer)

< means "is less than" and > means "is greater than" < (less) and > (greater) < (Less) and > (greater) < (L) think of spelling less with an italicized capital L and they look very similar if you're in Algebra ll, then you already know that...

i=prt 60,210=5%(x)+11%(4x+44,000) where x=amount invested at 5% 60,210=0.05x+0.44x+4840 60,210=0.49x+4840 60,210-4840=0.49x 55,370=0.49x 5,537,000=49x x=5,537,000/49 x=\$113,000 invested at 5% 4x+\$44,000=4(\$113,000)+\$44,000=\$452,000+\$44,000=\$496,000...

y=kx^r y=4/x can be written as y=4x^(-1)

11=(4)/(0.4)+(4/4) 19=(4!)-4-(4/4) because 4!=4*3*2*1=24

x+3y=4 2x+3y=2 by substitution... x+3y=4, x=4-3y 2x+3y=2 2(4-3y)+3y=2 8-6y+3y=2 8-3y=2 -3y=2-8 -3y=-6 y=2 x+3y=4 x+3(2)=4 x+6=4 x=4-6 x=-2 (-2,2) is the solution

Bee, maybe I can help a little. the decimal is 0.583333... look at the repetend only, not the lag the repetend is made up of the 3s and the lag is 58 the lag is what precedes the repetend how many different digits repeat ? only one, the 3 let x=0.58333... multiply...

let m=money let x= cost of one pencil m-3x=\$0.49 m-5x=\$0.15 subtract the equations 2x=\$0.34 x=\$0.34/2 x=\$0.17, the cost of one pencil m-(3)(\$0.17)=\$0.49 m-\$0.51=\$0.49 m=\$0.51+\$0.49 m=\$1.00, or m-(5)(\$0.17)=\$0.15 m-\$0.85=\$0.15 m=\$0.85+\$0...

line 4 should be  =2x-9-x+1/x-5 because -(x-1)=-x+1 line 5 then would be x-8/x-5 by the way, try to use parentheses  to make your work easier
