Answer:
39.43 for each dog
Step-by-step explanation:
<u>d = 2c (given) </u>
164 c + 23 d = 4140 sub in the above equation for d
164 c + 23<u> (2c)</u> = 4140
210c = 4140
c =19.71
d = 2c = 39.43

Part 1)
Part 2) There are about
Step-by-step explanation:
Part 1) we know that
1 month=4 weeks
Let
x------> the number of hours of practice for three months
so

3 months=3(4)=12 weeks
using proportion
that means------> In three months (12 weeks) the pianist practice 180 hours
Part 2)
Let
x------> the number of bass
y------> the number of catfish
we know that
Using proportion
There are about
Answer:
Step-by-step explanation:
Given function is,
f(x) =
To find the inverse of this function,
Rewrite the function as a equation,
y =
Interchange x by y and y by x,
x =
Now solve this equation for y,
x - 4 =
(x - 4)³ =
(x - 4)³ = 8y
y =
Now convert the equation into function,
Answer:
x = 28⁰
Step-by-step explanation:
sum of the angles of a triangle = 180⁰
∠A + ∠B + ∠C = 180⁰
∠A = 5x - 60⁰
∠B = 2x + 40⁰
∠C = 3x - 80⁰
<h2>:- Solution</h2>
∠A + ∠B + ∠C = 180⁰
5x - 60 + 2x + 40 + 3x - 80 = 180⁰
5x + 2x + 3x - 60 + 40 - 80 = 180⁰
10x - 20 - 80 = 180⁰
10x - 100 = 180⁰
10x = 180 + 100⁰
10x = 280⁰
x = 280⁰/10
x = 28
