30).
Sarah's hourly wage . . . . . . . w
Sarah worked last week . . .  (5 + 3) = 8 hours
Sarah's total pay last week . . . (5w + 3w) = 8w

31).
Noah's hourly wage . . . . . . . w
Noah worked last week . . .  8 hours
Noah's total pay last week . . . 8w

32).
Yes !  By golly, the expressions are equivalent.

Sarah and Noah are both paid for the number of
hours that they work in a week.  It doesn't matter
how the hours are spread out during the week.
Only the total number of hours in the week is what counts.

Sarah worked on two days and Noah worked on only
one day, but they both worked the same number of hours,
so they both earned the same total pay last week..

Find the zeros for (x+7) (x+5)+0
JulijaS [17]

Steps to solve for the zero:

(x + 7)(x + 5) = 0

~Set both factors to equal zero

x + 7 = 0

x + 5 = 0

~Solve for x in [ x + 7 = 0 ]

x + 7 = 0

x + 7 - 7 = 0 - 7

x = -7

~Solve for x in [ x + 5 = 0 ]

x + 5 = 0

x + 5 - 5 = 0 - 5

x = -5

Therefore, the solutions are x = -7 and x = -5

Best of Luck!

The sum of two numbers is 2490 and if 6.5 percent of one no. is equal to 8.5 percent of the other, then numbers are ?? Make sure
lions [1.4K]

Answer:

The two number are :

x = 1411

y = 1079

Step-by-step explanation:

Let the two numbers = x and y

The sum of two numbers is 2490

x + y = 2490..... Equation 1

If 6.5 percent of one no. is equal to 8.5 percent of the other,

Hence:

6.5% of x = 8.5% of y

0.065x = 0.085y

Make x the subject of the Formula

x = 0.085y/0.065

x = 1.308y

We substitute 1.308y for x Equation 1

x + y = 2490..... Equation 1

1.308y + y = 2490

2.308y = 2490

y = 2490/2.308

y = 1078.8561525

y = 1079

x + y = 2490..... Equation 1

x = 2490 - y

x = 2490 - 1079

x = 1411
