Answer:
1
Step-by-step explanation:
a+1=1
a=1-1
a=0
b^a which means:
b^0
whenever power is 0 answer is always one
so value of b^a is 1
Answer:
3 groups
Step-by-step explanation:
Sopranos = 12
Altos = 9
Find the highest common factor of 12 and 9
12 = 1, 2, 3, 4, 6, 12
9 = 1, 3, 9
The highest common factor of 12 and 9 is 3
Therefore, the choir teacher can only have 3 groups
12 sopranos / 3 groups
= 4 sopranos per group
9 Altos / 3 groups
= 3 altos per group
Each of the 3 groups Will have 4 sopranos and 3 altos each
3 times 8 times 1 eqals 24
To find the solution to this, we need to use the substitution method.
y = -5x + 3
Substitute the value for y.
y =1
1 = -5x + 3
Now, solve for x.
1-3 = -5x + 3 Apply the inverse operation to both sides of the equation.
-3
1-3 is -2
-2 = -5x
-5x/-5 = -2/-5
x = 0.4
Final answer:- x = 0.4 y = 1
