Answer:
the answer is 32
Step-by-step explanation:
the sum of angles in a triangle is 180° and if we subtract 116 from that we get 64. now since the sides of the triangle are the same we need to divide 64 with 2 and we get 32
Answer: the system of linear equations to represent this scenario are
b + g = 30
2b = g + 12
Step-by-step explanation:
Let b represent the number of boys in the class.
Let g represent the number of girls in the class.
There are 30 students in the math class. This can be expressed as
b + g = 30
There are 6 more boys than 1/2 the number of girls in the class. This can be expressed as
b = g/2 + 6
Cross multiplying by 2, the expression becomes
2b = g + 12
Answer:
5
or 18.03
Step-by-step explanation:
Let's call the unknown leg x
Using the Pythagoras rule
19^2 = 6^2 + x^2
361 = 36 + x^2
subtract 36 from both sides
361 - 36 = x^2
325 = x^2
Take the square root of both sides
= 
= x
x = 5 = 18.03
<em>Use the Negative Power Rule: x^-a = 1/x^a</em>
A)
X/3 -2 = 6
Add 2 to both sides:
X/3 = 8
Multiply both sides by 3:
X = 24
B)
X/5 +1 = 5
Subtract 1 from both sides:
X/5 = 4
Multiply both sides by 5:
X = 20
