Substitution Property of Equality
Step-by-step explanation:
The substitution property of equality states that if x = y, then x can be substituted in for y in any equation, and y can be substituted for x in any equation.
In this case, m∠A + m∠B in the second equation is substituted by 88°, from the first equation. This allows as to find m∠C as follows:
88° + m∠C = 150°
m∠C = 150° - 88° = 62°

n=140 the number of nickels.
1140-140=1000 pennies.
proof:
.01*1000+.05*140=17
10+7=17
17=17</span>
q1: 45% bc u have to divide the amount of pens w the total amount of students which is 90/200 and that’s 0.45, also 45%
q2: 9.5% bc now u have to divide the amount of pens only left handed students use, so when u find how many pens left handed students use, that’s 19, and again, u must divide it w 200 so 19/200 equals to 0.095 which is also 9.5%
q3: no
q4: not sure but i think the answer is no
3) $28 bc, 18+10= 1/3 of the money bc he already spent 2/3 so 28 is the answer
