kati45 [8]

we are given

Jim can lay bricks for a fireplace and chimney in 5 days

Jim's 1 day work is

=\frac{1}{5}

we are given

With his father's help he can build it in 2 days

so, both can do same work in 2 days

so, both's 1 day work is

=\frac{1}{2}

Let's assume

his father to build it alone in x days

his father 1 day work is

=\frac{1}{x}

so, both's 1 days work is

=\frac{1}{x}+\frac{1}{5}

so, we can set it to 1/2

we get

\frac{1}{2}=\frac{1}{x}+\frac{1}{5}

now, we can solve for x

\frac{1}{2}=\frac{5*1}{5*x}+\frac{1*x}{5*x}

\frac{1}{2}=\frac{5+x}{5x}

now, we can cross multiply

5x=2(5+x)

5x=10+2x

3x=10

now, we can solve for x

x=\frac{10}{3}

so,

his father to build it alone is

=\frac{10}{3}days............Answer

Choose the fragment that best completes the following sentence. Interest charges will not be applied to a credit card when-
aliya0001 [1]

Answer:

A.) the balance is payed off during the grace period  

Step-by-step explanation:

Paying only the minimum payment would cause the remainder of the balance to draw interest charges, whether paid during the grace period or before the due date.

Paying off the balance during the next billing cycle will still result in interest charges for the current billing cycle.

Paying off the balance during the grace period, however, will not result in interest charges.
