The top question is 17/15 or 1 2/15 but I dont get the second part
Step-by-step explanation:
To get my answer I first found a common denominator and multiplied each fraction to fit it, then I added the fractions and got 17/15, next I turned it into a mixed fraction by dividing 17 by 15 and I got 1 2/15 which cannot be simplified.
) A coin collection consisting of pennies, dimes, and quarters totals 45 coins. The number of
quarters is five more than twice the number of pennies and the number of dimes is four
more than the number of pennies. How much is the coin collection worth?/
9514 1404 393
Answer:
$7.14
Step-by-step explanation:
Let p, d, q represent the numbers of pennies, dimes, and quarters in the collection, respectively.
p + d + q = 45 . . . . . . . . there are 45 coins in the collection
2p +5 = q . . . . . . . . . . . . 5 more than twice the number of pennies
p + 4 = d . . . . . . . . . . . . . 4 more than the number of pennies
Substituting the last two equations into the first gives ...
p +(p +4) +(2p +5) = 45
4p = 36 . . . . . . . . . . . . . subtract 9
p = 9 . . . . . . . . . . . divide by 4
d = 9 +4 = 13
q = 2(9) +5 = 23
The value of the collection is ...
23(0.25) +13(0.10) +9(0.01) = 5.75 +1.30 +0.09 = 7.14
The coin collection is worth $7.14.

This circle is centered at the origin, and the length of its radius is 2. What iS
the circle's equation?
Answer:
Step-by-step explanation:
If the center of the circle is at the origin, the general formula for the circle is
x^2 + y^2 = r^2.
Since r = 2 units in this particular problem, the equation of the circle is:
x^2 + y^2 = 2^2, or x^2 + y^2 = 4

Round to nearest tenth
Answer:
Step-by-step explanation:
this is exactly the same as the 1st one, just they put it in a different orientation. sooo use law of cosines , where
QR = c
a = 12
b = 23
cos(120) = cos (P)
c = sq rt [ a^2+b^2﹣2*a*b*cos(P) ]
QR = sq rt [ 12^2 + 23^2 - 2* 12*23*cos(120) ]
QR = sq rt [ 144 + 529 - 552 * (-0.5 0 ]
QR = sq rt [ 673 + 276 ]
QR = sq rt [ 949 ]
QR = 30.8058
rounded to nearest 10th is
QR = 30.8 :)

If 2x - 3y = 24 and 3x + 4y = 2, what is the value of x - y?
Answer:
2x-3x=24____eqn 1
3x+4y=2____eqn 2
solve eqn 1 and 2 simultaneously using elimination method
eliminate x use the coefficients of x in the two equations to multiply each other i.e
3(2x-3y=24)
2(3x+4y=2)
6x-9y=72
6x+8y=4
eliminate x using the subtraction sign(-)
6x-6x-9y-(+8y)=72-4
-9y-8y=68
-17y=68
divide both side by the coefficient of y
y=68/-17
y=-4
put y=-4 in eqn 2
3x+4y=2
3x+4(-4)=2
3x-16=2
collect like term
3x=2+16
3x=18
divide both side by the coefficient of x
x=18/3
x=6
since we're asked to find x-y
6-(-4)
6+4=10
