Answer:
James is 37, Rob is 44, and Kate is 35
Step-by-step explanation:
Set up an equation where x is James' age:
Rob's age can be represented by x + 7, since he is 7 years older than James
Kate's age can be represented by x - 2, since she is 2 years younger than James
Add these together in the equation and set it equal to 116:
(x + 7) + (x - 2) + (x) = 116
Add like terms and solve for x:
(x + 7) + (x - 2) + (x) = 116
3x + 5 = 116
3x = 111
x = 37
So, James is 37.
Find Rob's age by adding 7 to this:
37 + 7
= 44
Find Kate's age by subtracting 2:
37 - 2
= 35
So, James is 37, Rob is 44, and Kate is 35
You can convert them to decimals and multiply. Remember when using decimals, it is over 10 or 100 <span />
F(x)=7x-1/2
Add the half to the other side afeterreplacing f(x) with a zero
1/2=7x divide by 7
7/2=x, when y=0
Answer:
figure please...... I cant see the figure
I'm pretty sure it's 4x+6x²-9
