Answer:
Her equation system is incorrect
Step-by-step explanation:
Remember that
1 dime=$0.10
1 quarter=$0.25
Let
x------> the number of quarters
y-----> the number of dimes
we know that
0.25x+0.10y=20.70 ------> equation A
x=10+y -----> equation B
Her equation system is incorrect, because in her second equation she exchanged the variables, using x instead of y and y instead of x.
Juan makes $360 a week and Thomas makes $350 a week, so Juan earns more a week
Formula to convert F to C:
(F -32) x 5/9
F = 63 + 10 = 73
73-32 = 41
41 x 5/9 = 22.77777
Rounded to the nearest degree = 23 C
