If the 0 and 2 are powers it would be 16^0=1, 2^2=4
Now we have 1+4*y-1.
Im not sure if you want parenthesis to make it 1+4(y-1) or not.
Solving for the first one it would simplify to 4y.
With the parenthesis it would be 4y-3.
Thats it simplified, if it is equal to something you would solve for y.
Let A, B and C be the number of pounds of each brand of coffee.
A+B+C=51 (weight) which is 3A+B=51 because C=2A, B=51-3A
15.99A+13.21B+19.90A=51×12.82=653.82 (cost) I’ve used C=2A
35.89A+13.21B=653.82
Substitute for B:
35.89A+13.21(51-3A)=653.82
35.89A+673.71-39.63A=653.82
3.74A=19.89, A=117/22 pounds, B=771/22 pounds, C=117/11 pounds.
Approximate weights are A: 5.32lb, B: 35.05lb, C: 10.64lb.
Answer:
P = 7
Step-by-step explanation:
46+8=54
54-5=49
49÷7=P
-First we have to work out what’s in parenthesis.
(8*10^-3)=(8*0.001)=0.008
-This is for the second parenthesis
(2*10^-4)=(2*0.0001)=0.0002
-Now we multiply them together
ANSWER: 0.0000016
