Anyone know how to do this or has the answer?? Much appreciated ☺️

$200

Step-by-step explanation:

For this one, you want to make algebraic equations. In this case, they would be r+7v=120 and r+10v=150 (where r is the register fee and v is the cost of a visit).

To solve simultaneous equations with a like term (when they have the same sign in front), you can solve by subtracting one equation from the other. This gives (r-r)+(10v-7v)=(150-120) or 3v=30, which can be solved to v=10.

To work out r, we can sub the known value of v (10) for v in either equation. This gives r+(10×10)=150 or r+100=150. This can be solved to r=50.

This makes the expression c=50+10n (where c is the total cost and n is the number of visits.

Lisa went 15 times, so this becomes c=50+(10×15) or c=50+150, which gives c=200.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
