Josh and Katya both work at a library making $9 per hour if Katya work seven more hours than Josh last week and they made $279 combined how many hours did Katya work​

Answers

Answer:

19 hours

Step-by-step explanation:

You have 279. First, devide the 279 by 9(dollar amount).

279/9 = 31

So combined they work 31 hours. Subtract 7 from this, since we know Katya worked 7 extra hours. Youll now have 24.  (31-7 = 24)

Next, divide this number in half, which will get you what they both worked before Katya worked an extra 7 hours.

24/2 = 12.

Now that we know they both worked 12 hours, we can just add back the 7 hours Katya worked.

12+7 = 19.

So the answer to how many hours katya worked will be:

19 hours

Desmond really like Legos. Last Saturday Desmond counted his Legos and realized that

he has 65 altogether! Desmond has 7 less green Legos than red Legos, and the amount of

blue Legos he has is two more than three times his red Legos. How many of each color

Lego does Desmond have?
Answer Quick.
Only reply if you have the answer please

Answers

Answer: 14 red, 7 green, 44 blue

Step-by-step explanation:

First, use the letter r as a variable to represent the number of red Legos. The number of green Legos (g) is 7 less than the number of red Legos, or g = r-7. The number of blue Legos (b) is 2 more than 3 times the number of red Legos, or b = 3r+2. The total number of Legos is the number of red + green + blue Legos, which can be represented as 65 = r+g+b.

Substitute the equations for g and b in. This should give you a final equation of 65 = r+(r-7)+(3r+2). To solve for the number of red Legos, first add up all of the terms to get 65 = 5r-5. Now add 5 to each side (70 = 5r). Finally, divide each side by 5 (r = 14).

To find the number of green Legos, substitute the number of red Legos (14) into the equation for the green Legos (g = r-7). This should get you the equation g = 14-7 which simplifies to g = 7.

To find the number of blue Legos, substitute the number of red Legos (14) into the equation for the blue Legos (b = 3r+2). This gives you the equation b = (3*14)+2. First, multiply 3 and 14 to get b = 42+2. Finally, add them together to get b = 44.

Tamekia and Marsha mow lawns during the summer to earn money. Tamekia determined that she can earn between $6.00 and $6.25 per hour. Marsha estimates that she earns between $7.50 and $8.00 per hour. About how much more money will Marsha earn than Tamekia if they each work 22 hours?

Answers

Answer:

$33 - $38.50

Step-by-step explanation:

Tamekia $6.00 -  $6.25

y = mx

y = (22)(6) = 132

y = (22)(6.25) = 137.50

$132 - $137.50

Marsha $7.50 - $8.00

y = (22)(7.5) = 165

y = (22)(8) = 176

$165 - $176

Two similar solids have surface areas of 48cm and 108cm respectively.find the volume of the smaller solid if the bigger one has a volume of 162cm​

Answers

Answer:

The volume of the smaller solid is 72 cm.

Step-by-step explanation:

Given that two similar solids have surface areas of 48cm and 108cm respectively, to find the volume of the smaller solid if the bigger one has a volume of 162cm the following calculation must be performed:

108 = 162

48 = X

48 x 162/108 = X

7776/108 = X

72 = X

Therefore, the volume of the smaller solid is 72 cm.
