Lisa has a certain amount of money. She spent 39 dollars and has 3/4th of the original amount left. How much money did she have

harina [27]

If $\frac { 3 }{ 4 }$ is left, that means $\frac { 1 }{ 4 }$ was spent. So $\frac { 1 }{ 4 }$ of the total amount is equal to 39.. Let's say x to the total amount. $\frac { 1 }{ 4 } \cdot x=39\\ x=4\cdot 39\\ x=156\\$

the elves were working when the head elf came in and there was only 2 weeks left until christmas. what percentage of the month w

valentina_108 [34]

Answer:

45 %

Step-by-step explanation:

Time left until Christmas = 2 weeks

= 2 * 7 days [since 1 week = 7 days]

= 14 days

Number of days in December = 31

Percentage of the month left before Christmas = $\frac{Time left until Christmas}{Number of days in December} * 100$

= $\frac{14}{31} * 100$

= 0.45 * 100

= 45 %

Find the measure of the largest angle in the triangle shown . PLS HELP

Andre45 [30]

Answer:

72°

Step-by-step explanation:

So the three angles of a triangle always add up to 180°. This means that

$15x + 21x + 24x = 180$

This becomes:

$60x = 180$

And solves as:

$x = 3$

The largest angle has to be the one marked with 24x because it has the largest coefficient and x is a constant.

$24x = 24(3) = 72$

The measure of the largest angle in the triangle is 72°.
