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:
u = 7
Step-by-step explanation:
In a parallelogram, GI = GK so:
u + 28 = 5u
4u = 28
u = 7
Answer:
Step-by-step explanation:
nine more then a number is eleven
let the number be n
n + 9 = 11 <=== ur equation
n = 11 - 9
n = 2
