a = 11
Step-by-step explanation:
a + 15 = 3a - 7
-a -a
15 = 2a - 7
+7 +7
22 = 2a
/2 /2
11 = a
Answer:
0.65g
Step-by-step explanation:
Decay rate = 50%
Decay rate = 0.5

where Ao = initial amount at start, k = rate of decay or growth, t = time, e = euler's number and A = value at time 't'
Ao = 4.8
t = 88/44 = 4
k = 0.5
substitute these values in the equation



The answer is c trust me it is c trust me the answer is c just trust me it is c
Allright to find this you have to put the equation into order again. The equation of a line is y=mx+c. M= Gradient. C = Y intercept. After you put it in order you just have to read it. If you need the answers comment ill find them...
Answer:
45
Step-by-step explanation:
c^2*b
We know that c is 3, and b is 5, so we can substitute them in
3^2*5
Solve the exponent first
9*5
Multiply
