Answer:
c is hypotenuze,a is the smallest , b is the one who is left
Step-by-step explanation:
Let x = volume of saline solution A,
y = volume of saline solution B.
We're going to set up two equations.
Firstly, x + y = 6. That gives us y = 6 – x (1)
Second, 0.1x + 0.05y = 0.08•6,
or 0.1x + 0.05y = 0.48 (2)
Substitute (1) into (2):
0.1x + 0.05(6 – x) = 0.48
0.1x + 0.3 – 0.05x = 0.48
0.05x + 0.3 = 0.48
Subtract 0.3 from both sides:
0.05x = 0.18
x = 3.6
Then y = 6 – 3.6 = 2.4
So we have to use 3.6 litres of solution A and 2.4 litres of solution B.
A straight line is 180 degrees
Answer:
265/99
Step-by-step explanation:
Let X equal the decimal number
Equation 1:
X=2.67 (67 repeating)
With 2 digits in the repeating decimal group,
create a second equation by multiplying
both sides by 102 = 100
Equation 2:
100X=267.67 (67 repeating)
Subtract equation 1 from equation 2
100X = 267.67 (67 repeating)
X = 2.67
We get :99X = 265
Solve for X
X=265/99
