It is -7/2 when the variables are substituted
Answer:
1) 133⅓ %
2) 112½ %
Step-by-step explanation:
1) 2 years = 2×12 = 24 months
24/18 × 100 = 133.33%
2) 225mm = 225/10 = 22.5 cm
22.5/20 × 100 = 112.5%
Answer:
9 teaspoons are needed
Step-by-step explanation:
multiply 3 teaspoons by 3 cups to find the answer.
the answer is 9 teaspoons.
The best method would be to cross-multiply. Multiply the figure on the top left with the bottom right. Then set it equal to the multiplication of the bottom left with the top right.
This would turn into:
-1(x-1)=2(x+3) Then distribute the multiplication through the parentheses.
-x+1=2x+6 Next, get all the variables on one side, and the integers on another.
2x+x=1-6
3x= -5
x= -5/3
So if F (×)= 56. When x= 8.
56÷8 = 7
F=7
F(×) = ? when X = 2
7 × 2= 14
F (x) = 14
Hope this helps!
