A) N + D = 30
B) .05N + .1D = 2.20
Multiplying equation A by -.05
A) -.05N -.05D = -1.50 then adding it to B
B) .05N + .1D = 2.20
.05D = .70
Dimes = 14
Nickels = 30 -14 = 16

Answer: Kristin bought 6 Math books and 5 English books.
Step-by-step explanation: Let x be the number of math books and y the number of english books.
Relation: 306=26x+30y
11=x+y
Solve using elimination method so you would get that y=5 then replace y=5 in the first equation to find x which is 6
(4)(-9) + 2 (-1) = - 38

Answer:
70 degrees, 21 degrees, 37 degrees
Step-by-step explanation:
For the rectangle
- Angle B= 90 degrees<em> (right angle)</em>
Find Angle AED = 180-46-90=44 degrees
All angles add up to 180 so we can find x
66+44=110, therefore Angle x = 180-110=70 degrees
XYZ is equilateral therefore all angles = 60 degrees
This allows us to find angle WZX, 180-60=120
Angle X=180-120-39=21 degrees
PQR is isoceles so the base angels are equal QRP=71 degrees
180-71=109 degrees. 180-109-34=37 degrees = Angle X
Good Luck!!
