Answer:
x>2
Step-by-step explanation:
The answer for the blank space is 21.8
2a + 3p = 1.59
a = 0.24
Plug it in our equation:
2(0.24) + 3p = 1.59
Multiply:
0.48 + 3p = 1.59
Subtract 0.48 to both sides:
3p = 1.11
Divide 3 to both sides:
p = 0.37
So one pair costs <span>£0.37</span>
Answer:
1. a=3
2. a=3
3. a=9
Step-by-step explanation:
1. 9/a+9-4=12-56/8+3
We move all terms to the left:
9/a+9-4-(12-56/8+3)=0
Domain of the equation: a=0
a∈R
We add all the numbers together, and all the variables
9/a+9-4-8=0
We add all the numbers together, and all the variables
9/a-3=0
We multiply all the terms by the denominator
-3*a+9=0
We add all the numbers together, and all the variables
-3a+9=0
We move all terms containing a to the left, all other terms to the right
-3a=-9
a=-9/-3
a=+3
