Answer:
2x+59.
Step-by-step explanation:
Let <em>J </em>represent Jessica's weight and <em>R</em> represent Ronda's weight.
Jessica weighs <em>x+34</em> pounds. Thus:

Ronda weighs 12 pounds less than Jessica. In other words:

The sum of their weights, therefore, is:

Now, if Jessica gains 5 pounds and Ronda loses 2 pounds, the net gain of the total weight would be 3 pounds. Thus, we only need to add 3 to the original total to find the sum of their new weights:

The sum of the new [weights] is represented by 2x+59.
Answer:f(1)=-4, f(1)=1
Just substitute the value to the x, Like this.
F(x)=x²+2x-7
F(1)=(1)²+2(1)-7
=1+2-7
=3-7
=-4
Step-by-step explanation:
Answer:
6 times
Step-by-step explanation:
1. There was no cents left
2. If you roll one and get 50 cents you have to minus it with rolling other number than 'one' 5 times because you'll get 10 minus if you roll another number (50 divided by 10 is 5)
3. If you divid 30 (The rolls) by 5 (amount of roll you have to roll if you get one)
4. It equals 6 and 6 is a even number
5. Sorry this was too confusing
We need more info that can’t be the whole question
Given data:
The given distance Jadwiga runs in a day is 875 m.
The expression for the given statement is,
1d=875 m
Multiply the above expression by 7 on both sides.
7(1 day)=7(875 m)
=6,125 m
=6.125 km
Thus, Jadwiga covered 6.125 km in 7 days.
