Answer:
a. (x+5)^2 = 49
b. (x+7)^2 = (x+1)^2
Step-by-step explanation:
So the term "a number" is always going to be x. input x into the sentences. "X plus five, then squared, is forty-nine". when they do "is __", that means equal to. In the second question, seven more than x is x + 7 (the two numbers are interchangeable here). Equivalent also means equal. hope this helped :)
Answer:
The plumbers cost would be equal to the equation 80+45x=y with y being the total amount of money he made and x being how many hours he worked.
Step-by-step explanation:
In this equation to find the amount the plumber was paid all you need to do is plug in the amount of hours he worked for x.
If the plumber worked his maximum of 8 hours then the equation would change from 80+45x=y to 80+(45×8)=440.
So, if the plumber worked for 8 hours he would make $440.
Answer:
x is greater than or equal to 19
Answer:

Step-by-step explanation:
Answer:
8. 5/6
9. 6.25, 6 and 1/4
10. 14.4
Step-by-step explanation:
Sorry that this is a little late. All of these problems end up with the same process to get to the answer. Since you want to find the rate, you would want to divide the amount of time taken by itself to find the unit rate. So basically, 8. would be 20 cm in 24 hours. You would divide both by 24 and you get 20/24 cm in 1 hour. and then you simplify the fraction and boom, there's your answer.
