Answer:
1. s + 7 = 9
2. 5r - 4 = 21
3. t - s = 5
4. u + r = 6
5. 11t - 7 = 70
6. 6 + 3u = 9
7. 4r - 10s = 0
8. r with an expnent of 2 +8 = [tex]r^{2} + 8 = 33[/tex]
9. 30 over r = [tex]\frac{30}{5}[/tex] =6
10. 2t with an exponent of 2-18 = [tex](2t)^{2} - 18 = 178[/tex]
Step-by-step explanation:
1. If r = 5, s = 2, t = 7, and u = 1 then,
s + 7 = 2 + 7 = 9
2. If r = 5, s = 2, t = 7, and u = 1 then,
5r - 4 = 5(5) - 4 = 25 - 4 = 21
3. if r = 5, s = 2, t = 7, and u = 1 then,
t - s = 7 - 2 = 5
4 .If r = 5, s = 2, t = 7, and u = 1 then,
u + r = 1 + 5 = 6
5. If r = 5, s = 2, t = 7, and u = 1 then,
11t - 7 = 11(7) - 7 = 77 - 7 = 70
6. If r = 5, s = 2, t = 7, and u = 1 then,
6 + 3u = 6 + 3(1) = 6 + 3 = 9
7. If r = 5, s = 2, t = 7, and u = 1 then,
4r - 10s = 4(5) - 10(2) = 20 - 20 = 0
8. If r = 5, s = 2, t = 7, and u = 1 then,
r with an exponent of 2 +8 = [tex]r^{2} + 8 = 5^{2} + 8 = 25 + 8 = 33[/tex]
9. If r = 5, s = 2, t = 7, and u = 1 then,
30 over r = [tex]\frac{30}{r} = \frac{30}{5} = 6[/tex]
10.If r = 5, s = 2, t = 7, and u = 1 then,
2t with an exponent of 2-18 = [tex](2t)^{2} - 18 = (2.7)^{2} - 18 = (14)^{2} - 18 = 196 - 18 = 178[/tex]
