Answer:
If 2p + 6a = $14
and 3p + 9a = $21
then the following would also be true:
1p + 3a = $7
If p = pear and a = apple, how much would each cost? The unit prices can be determined by looking at the pattern. You can use multiplication to solve the problem.
For example, 1p + 3a*2 = $7
p = $1/each
a = $2/each or $6 total
Answer:
C) 15
Step-by-step explanation:
This is following the 30-60-90 triangle ratio which goes x (leg) ,x sqrt 3 (leg), 2x (hypotenuse).
So multiply 7 1/2 by 2 to get 15
Answer:
f, s={36,6} is your answer.
Step-by-step explanation:
PREMISES
6s+9=3(s+9)
ASSUMPTIONS/SUFFICIENT CONDITION(S)
Let the son's current age s=s
Let the father's current age f=6s
CALCULATIONS
6s+9=3(s+9)
6s+9=3s+27
6s-3s+(9–9)=3s-3s+(27–9)
3s+0=0+18
3s=18
3s/3=18/3
s=
6
and,
if s=6, then
6s=
f=
36
PROOF
If f,s=36, 6, then the equations
6s+9=3(s+9)
6(6)+9=3(6+9)
36+9=3(15) and
45=45 establish the roots (zeros) f, s=36,6 of the mathematical statement 6s+9=3(s+9)
