Answer:
The required solution is (0.128,13.82)
Step-by-step explanation:
Consider the provided system of equation.
......(1)
......(2)
We need to solve the system of equation by substitution method.
Consider the equation 1.
......(3)
Substitute the value of y in equation 2.
Now substitute the value of x in equation 3.
Hence, the required solution is (0.128, 13.82)
Answer:
area= 7/8×8/5 = 7/5 =1.4 sq feet
1÷3=13.
Step-by-step explanation:
To find the reciprocal of any number simply take 1 and divide it by that number, so the reciprocal of 3 is 1÷3=1/3. We can check that this is the multiplicative inverse of 3 by multiplying those two numbers together and seeing if we get 1: so 3×1/3=3×1/3=1. Where it says =3 you put a line through that 3.
Answer:
It is c
Step-by-step explanation:
First, note that x+21 and 3x+9 are "complementary angles;" they add up to 90 degrees. Thus, 4x + 30 = 90 degrees, so that 4x = 60 degrees, and x = 15 degrees.
