Answer:

Jody

Step-by-step explanation:

You can either convert 500 seconds to minutes or 8 minutes to seconds to compare. I'll do both.

There is 60 seconds in a minute. To find the total minutes of 500 seconds, divide 500 by 60 → 8.3, which means that Jody practiced for 8.3 minutes.

To find the total seconds of 8 minutes, multiply 60 seconds per minute by 8 minutes → 60 * 8 = 480 seconds which means that Bill practiced for 480 seconds.

Now you can compare. Jody practiced for 500 seconds, or 8.3 minutes. Bill practiced for 480 seconds, or 8 minutes. Jody practiced longer.

Mrac [35]

Answer:

11 gallons of paint Jay needed for the inside .

Step-by-step explanation:

Consider the provided information.

Let x is the quart of paint Jay needed for the outside.

Let y is the quart of paint Jay needed for the inside .

Jay needs 19 quarts more paint for the outside of his barn than for the inside.

$x=y+19$

He uses 107 quarts in all,

$x+y=107$

Substitute the value of x in above equation.

$y+19+y=107$

$2y=107-19$

$2y=88$

$y=44$

Hence, 44 quarts of paint Jay needed for the inside .

But we need to find how many gallons of paint will be used to paint the inside of the barn.

So convert 44 quarts into gallon.

1 quarts = 0.25 gallon

1×44 quarts = 0.25×44 gallon

44 quarts = 11 gallon

Hence, 11 gallons of paint Jay needed for the inside .

35=3x+14 could anyone help me fast please I also need to show work!

Neporo4naja [7]

Answer:

$\boxed {\tt x=7}$

Step-by-step explanation:

We are given the equation

$35=3x+14$

We want to solve for x, therefore we must isolate x on one side of the equation.

14 is being added to 3x. The inverse of addition is subtraction. Subtract 14 from both sides of the equation.

$35-14=3x+14-14$

$35-14=3x$

$21=3x$

x is being multiplied by 3. The inverse of multiplication is division. Divide both sides of the equation by 3.

$\frac{21}{3} =\frac {3x}{3}$

$\frac{21}{3}=x$

$7=x$

Let's check our solution. Plug 7 in for x and solve.

$35=3x+14$

$35=3(7)+14$

$35=21+14$

$35=35$

This checks out, so we know our solution, x=7 is correct.
