Answer:
she can buy 6 dolls
Step-by-step explanation:
If you take a moment and solve each equation (find the value
of the letter in each one), it'll jump out at you.
Here, let me do it for you. Why should you tire yourself.
5x = 20 . . . . . x = 4
4b = 7 . . . . . . b = 7/4
8w = 32 . . . . . w = 4
12y = 48 . . . . . y = 4
The second equation is not like the others.
It's the only one where the letter is not equal to 4 .
The temperature was increasing between the 5 and the 7 mark, so 2 hours <span />
Just go to math papa. It solves all kinds of problems like these. Anyways the answer is a=4. Please give me a thanks.
When that expression is expanded, it becomes 49m-squared +70m+25. To me, the original form seems simpler.
