B = base length
a = length of the other two equal sides
The value of 'a' is larger than the value of b. This is because the base is shorter than the other two equal sides. We're told that "one of the longer sides is 6.3 cm", meaning that a = 6.3
Replace every copy of 'a' in the given equation with 6.3; isolate b
2*a + b = 15.7
2*6.3 + b = 15.7
12.6 + b = 15.7
12.6 + b - 12.6 = 15.7 - 12.6 ... see note below
b = 3.1
note: I subtracted 12.6 from both sides. This is using the subtraction property of equality.
Answer:
y = 8
Step-by-step explanation:
sin(45 degrees) = √2/2
==> x = y = 8
Answer:
The value of n depends on the questin. N would be a variable in an equation.
Step-by-step explanation:
For example. 2*n=6
n is the variable in the equation. Therefore, the value of n is 3. Because 2*3=6.
He should have added 1 to both sides to make the -1 on the right go to 0.
Then it would be 0 + m = -16 + 1 = -15
You can check your work by adding -1 and -15, which does in fact equal -16.
Hope this helped :)
