Step-by-step explanation:
again, 2 unknowns.
x = number of 2- points baskets
y = number of 3- points baskets
we know they hit the basket 37 times in a so far unknown mixture of 2-point and 3- point throws.
x + y = 37
which gives us e.g.
x = 37 - y
and we know that with this unknown mixture they scored 80 points.
so,
2x + 3y = 80
as every successful 2-points throw scores 2 points, and every successful 3-points throw scores 3 points.
so, again our 2 equations :
x = 37 - y
2x + 3y = 80
remember, we prepared the first equation so that it gives us already an identity expressing one variable by the other. and that we use in the second equation :
2×(37 - y) + 3y = 80
74 - 2y + 3y = 80
74 + y = 80
y = 6
and from
x = 37 - y
we get
x = 37 - 6 = 31
so, they had 31 2-points throws and 6 3-points throws.
Answer:
26 = G. 27 = A. 28 = J
Step-by-step explanation:
26} A Nickle = 5 cents. A Dime = 10 Cents.
Way #1: 5+5+5+5+5+5 = 30
Way #2: 10 + 10 + 10 = 30
Way #3: 10 + 5 + 5 + 5 + 5 = 30
Way #4: 10+ 10+ 5 + 5 = 30
27} Pennies = 1 Cent. Nickels = 5 Cents. Dimes = 10 cents.
Way #1: 1+1+1+1+1+5+ 10 = 20
28} Pennies = 1 Cent. Nickels = 5 Cents. Dimes = 10 Cents.
Way #1: 10+5+1+1 = 17
Way #2: 5+5+5+11 = 17
Way #3: 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1 = 17
Way #4: 1+1+1+1+1+1+1+10 = 17
Way #5: 5+1+1+1+1+1+1+1+1+1+1+1+1 = 17
Answer:
39 and 86.
Step-by-step explanation:
39 and 86 equal 125 when added. When 47 is subtracted from 86 you get 39.
Answer:
x = 18, y = 45
Step-by-step explanation:
4x - 7 + a = 180 (linear pair)
But, a = 6x + 7 (alternate interior angles)
=> 4x - 7 + 6x + 7 = 180
=> 10x = 180
=> x = 18
Now, 3y - 20 = 6x + 7 (vertically opposite angles)
=> 3y - 20 = 6(18) + 7
=> 3y = 108 + 7 + 20
=> 3y = 135
=> y = 45
Hope it helps :)
