Answer:
Bob forgot to distribute 3 to 1.50 in the parentheses
Step-by-step explanation:
Bob made the mistake in his first step.
In the equation 3(x + 1.50) = 30, the 3 has to be distributed to both x and 1.50.
But, Bob only distributed it to x, which led him to get the wrong answer.
So, Bob's mistake when solving was that he forgot to distribute the 3 to 1.50
Answer:
16. r(s)(t) =
r=2, s=3, t=4
(2)(3)(4)=
(2*3) = 6 ---> 6(4) = 24
final: 24
17. (r)(s)(t)(x)(y) =
r = 2, s = 3, t = 4, x = 5, y = 6
(2)(3)(4)(5)(6)
2*3=6
6*4=24
24*5= 120
120*6=720
final: 720
18. (7x + 2Y) =
x = 5, y = 6
rewrite---> = [7(5) + 2(6)]
[35 + 12] = 47
final: 47
hope this helpsss sorry took a while LOL
Step-by-step explanation:
q = 1; r = 2; s = 3; t = 4; x = 5; y = 6

Answer:
After 7.5 years we will have enough money in the account to purchase the car.
Step-by-step explanation:
Amount needed to be saved = $10000
Principal = $6500
So, Simple Interest = $3500
Rate of Interest = 7.5%
= 0.075
Now, Simple Interest = Principal × Rate × Time
⇒ 3500 = 6500 × 0.075 × Time
⇒ 3500 = 487.5 × Time
⇒ Time = 7.18 years ≈ 7.5 years
Hence, after 7.5 years we will have enough money in the account to purchase the car.
