Pythagorean Theorem:
Step-by-step explanation:
The standard form of the
equation that represents the number of quarters, q, and the number of dimes, d,
that Austin has in his piggy bank is 5q + 2d = 270. This can be change to slope
intercept form to see the clearer picture. By dividing the whole equation by 2,
so the equation become d= -2.5q + 135.
<span>This means that Austin has
initially 135 dimes in his piggy bank and he is losing 2.5 dimes per quater</span>
Step-by-step explanation:
angle x is equal to 65
angles of triangle is equal to 180
Answer:
Step-by-step explanation:
5s + 6c = 23.91
2s + 7c = 17.89
10s + 12c = 47.82
-10s - 35c = -89.45
-23c = -41.63
c = $1.81 for a large coffee
2s + 7(1.81) = 17.89
2s = 5.22
s = $2.61 for a scone
