Answer:
Value of equation = 26.25
Step-by-step explanation:
Given:
Equation given
-4a² + 3ab - (2a + 3b)
Given value of a = 1/4
Given value of b = -12
Find:
Value of equation
Computation:
-4a² + 3ab - (2a + 3b)
By putting value of a and b
-4(1/4)² + 3(1/4)(-12) - [2(1/4) + 3(-12)]
-4(1/16) - (36/4) - [2/4 - 36]
-4/16 - 36/4 - [-142/4]
- 0.25 - 9 + 142/4
-0.25 - 9 + 35.5
Value of equation = 26.25
Answer:
value of y = 95°
Step-by-step explanation:
=》128° + 72° + 65° + y = 360°
( because sum of all angles
of a triangle = 360° )
=》265° + y = 360°
=》y = 360° - 265°
=》y = 95°
i hope you got it.
8 children were younger than 5 years old. 21 children were older than 7 years old
20% of 12 is
0.20 *12 = 2.4
12-2.4= 9.6
but wait, can you have 0.6 of a dog?
depending on whether you want to round up or down,
you're left with 9 or 10 dogs
