Point H is between points L and S. LS = 14x -21 LH = 15 HS = 8x What is the length of segment LS?Immersive Reader (5 Points)

Fofino [41]

Answer:

$LS = 63$

Step-by-step explanation:

Given

$LS = 14x - 21$

$LH = 15$

$HS = 8x$

Required

Determine the length of LS

Since H is between L and S, then

$LS = LH + HS$

Substitute 14x - 21 for LS, 15 for LH and 8x for HS

$14x - 21 = 15 + 8x$

Collect Like Terms

$14x - 8x = 21 + 15$

$6x = 36$

Divide both sides by 6

$x = 6$

Substitute 6 for x in $LS = 14x - 21$

$LS = 14(6) - 21$

$LS = 84 - 21$

$LS = 63$

Hence, the length of LS is 63 units

Rudiy27

Answer:

The money Rachael plan to collect for the shelter is $345.

Step-by-step explanation:

There are some data missing in the question, so below is the complete question:

Rachel is collecting donations for the local animal shelter. So far she has collected $245, which is 70% of what she hopes to collect. How much money does Rachel plan to collect for the shelter?

Now, to find the money Rachael plan to collect for the shelter.

Let the total money Rachael plan to collect be $x.$

The amount far she has collected = $245.

Percentage of amount she hopes to collect = 70%.

Now, to get the total money Rachael plan to collect:

$70\%\ of\ x=245$

$\frac{70}{100} \times x=245$

$0.70x=245$

Dividing both sides by 0.70 we get:

$x=\$345.$

Therefore, the money Rachael plan to collect for the shelter is $345.
