Answer:
4 quarters
10 tenths
Step-by-step explanation:
<h3>Tenths</h3>
<h3>Quarter</h3>
<h3>Whole</h3>
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
∴ There are <u>4</u><u> </u><u>quarters</u> to make a whole
∴ There are <u>10</u><u> </u><u>tenths</u><u> </u>to make a whole
this is system of equations
2x + 5y = -1 times this one by 5 to make the y's opposite
-10x -25y = 5
10x - 25y = -5 (this is it times by 5, now add them)
__________
0 + 0 = 0
now since everything cancels and both sides are equal it has infinite solutions beaus they are actually the same line.
Answer:
0.75 cup
Step-by-step explanation:
K + p + b = 2 1/4
K = p = b
Sence all beans are equal we can divide 2 1/4 by 3
2 1/4 / 3 = 3/4
Cost of month plan = $40
Cost of minutes used = $0.45 after 700 minutes
Total cost = $48.10
Let x be the total minutes used
Total cost = 40 + 0.45(x - 700)
------------------------------------------------------------------
Form the equation and solve x
------------------------------------------------------------------
40 + 0.45(x - 700) = 48.10
40 + 0.45x - 315 = 48.10
0.45x - 275 = 48.10
0.45x = 48.10 + 275
0.45x = 323.10
x = 323.10 ÷ 0.45
x = 718
