X + 5y = 8 -x + 2y = -1 How is this solved?

1 answer:

8 0

Add both the equations together to eliminate x

x+5y=8
-x+2y=-1

7y=7
y=1

Now fill in y into the original equation

x+5(1)=8
x+5=8
x=3

Now you can check by filling x and y into the second equation.

-(3)+2(1)=-1
-3+2=-1
-1=-1

So your answer will be (3, 1)

Felipe rented a truck for one day. there was a base fee of $14.95, and there was an additional charge of 87 cents for each mile

jeka94

<u>Answer</u>:

Felipe drove the truck for 1.26 miles

<u>Step-by-step explanation:</u>

Given :

Base fee = $14.95

Additional charge for each mile driven = 87 cents

Amount Felipe paid when he returned the truck = $124.57

To Find:

How many miles did he drive the truck =?

Solution:

Let number of miles Felipe drove be X

Then according to the question,

Base fare + 87(number of miles driven) = 124.57

Substituting the known values,

14.95 + 87(x) = 124.57

124.57- 14.95 = 87 x

109.62 = 8x

x = $\frac{109.62}{87}$

x = 1.26

The mountain trail at Tanner Park is 8 miles long traveling to the top of the mountain and back. Grayson is making his way back

AnnZ [28]

Answer:

Speed of hike = 1.7 miles per hour

Step-by-step explanation:

Given:

Total distance = 8 miles

Distance already traveled = 4.6 miles

Total time remain to travel = 2 hour

Find:

Speed of hike

Computation:

Distance remain = Total distance - Distance already traveled

Distance remain = 8 miles - 4.6 miles

Distance remain = 3.4 miles

Speed of hike = Distance remain / Total time remain to travel

Speed of hike = 3.4 / 2

Speed of hike = 1.7 miles per hour

The range means the y values. The points are written as: (x,y)

So, the right answer is {1,2,3} not the C because the range only needs to be told once.
