Answer:
r = -3
Step-by-step explanation:
Performing the indicated multiplication on both sides of this equation, we get:
5r - 5 = 2r - 8 - 6
Combining the r terms: 3r - 5 = - 8 - 6.
Combining the constants: 3r = 5 - 14, or 3r = -9.
Dividing both sides by 3, to isolate r, we get: r = -3
Its False. addition and subtraction, Multiplication and division are inverse operations.
The missing digit is number 3. The total amount should be $132
I multiplied 11 by the numbers 10 and above to get the possible three digit answer who has 1 as the first digit and 2 as the last digit.
11 x 10 = 110
11 x 11 = 121
11 x 12 = 132
The 11 members of the Middle School Math club each paid $12 for a guest speaker.
Answer
$79.45
Use the <em>simple interest formula</em>
A= P(1+rt)
A = 70(1+0.045×3)
And you solve, which gives you 79.45
g) c=1.98w is your answer
w = weight = 5.5
c = cost = 10.89
10.89 = 1.98(5.5)
10.89 = 10.89 (true)
hope this helps
