Answer:
<span>a=15</span>
Explanation:
<span>5a−10b=45</span> , when <span>b=3</span>
Substitute the value of b into the equation.
<span>5a−10<span>(3)</span>=45</span>
Solve for a.
<span>5a−10<span>(3)</span>=45</span>
<span>5a−30=45</span>
<span>5a=75</span>
<span>a=<span>15</span></span>

Answer:
They are not congruent
Step-by-step explanation:
...........The answer is C
Write and solve the appropriate exponential equation:
228 = 16(r)^4, where r is the change per hour in the number of bacteria:
228
------ = r^4 = 14.25.
16
Taking the fourth root of both sides, we get: r = 1.94 (answer)
