Answer:
x = 7
y = 4
Step-by-step explanation:
y + 12 = 3x - 5
5y - 4 = 3x - 5
So y + 12 = 5y - x
To solve the equation above, y =4
Sub y = 4,
x = 7
If A=((1/7)^-5 ) 3 , so A= (1/<span>7)^-15 (power property)
the answer is </span><span>b. (1/7 ) ^-15 </span>
Answer: $42.75
Step-by-step explanation:
Given: A home improvement store rents it’s delivery truck for $19 for the first 75 minutes and $4.75 for each additional 1/4 hour.
Since, 1 hour = 60 minutes
1/4 hour = 
If a customer rented the truck at 11:10 am and returned the truck at 1:40 pm the same day, what would his rental cost be
Time taken = 150 minutes
Since charge for first 75 minutes is fixed and charge of $4.75 for each additional 1/4 hour (15 minutes) is given by
The additional charge =![\frac{(150-75)}{15}\times4.75=23.75/tex]The total his rental cost =[tex]19+23.75=$42.75](https://tex.z-dn.net/?f=%5Cfrac%7B%28150-75%29%7D%7B15%7D%5Ctimes4.75%3D23.75%2Ftex%5D%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%3Cstrong%3EThe%20total%20his%20rental%20cost%20%3D%3C%2Fstrong%3E%5Btex%5D19%2B23.75%3D%2442.75)

Answer: Option D. 16
Solution:
If LM is a midsegment of IJK, it is joining the midpoint of the sides IJ and IK, and it's half the length of the base of the triangle (JK), then:
L is the midpoint of the side IJ, and divides it into two congruent parts:
IL=LJ
Replacing IL by 7x and LJ by 3x+4:
7x=3x+4
Solving for x: Subtracting 3x both sides of the equation:
7x-3x=3x+4-3x
Subtracting:
4x=4
Dividing both sides of the equation by 4:
4x/4=4/4
Dividing:
x=1
Then we can determine the length of LM:
LM=2x+6
Replacing x by 1 in the equation above:
LM=2(1)+6
LM=2+6
LM=8
and because LM is half the length of the base of the triangle (JK)
LM=(1/2) JK
Replacing LM by 8:
8=(1/2) JK
Multiplying both sides of the equation by 2:
2(8)=2(1/2) JK
16=(2/2) JK
16=(1) JK
16=JK
JK=16
