<h2>x = 1/4</h2><h2>y = -2</h2><h2>______________</h2>
<h2>Known : </h2>
y = -8x
4x - y = 3
<h2>Asked: </h2>
Use the substitution method to solve the system of equations ?
<h2>Answered:</h2>
<h3>Substitution y</h3>
4x - y = 3
4x - (-8x) = 3
4x + 8x = 3
12x = 3
x = 3/12
x = 1/4
<h3>
Substitution x</h3>
4x - y = 3
4(1/4) - y = 3
4/4 - y = 3
1 - y = 3
-y = 3 - 1
-y = 2
y = -2
If 80 miles is 50% of his trip, then you know that 80 miles is only HALF of his entire trip. To get the distance Raul traveled in total, simply double the 80 miles. This would be 160 miles.
Raul traveled a total of 160 miles in his trip.
B = 120 because it is in your sum
Answer:
174 square centimetres
Step-by-step explanation:
The formula for finding the surface area of a rectangular prism is
SA = 2LW + 2LH + 2HW
Therefore surface area will be
= 2(11*5) + 2(11*2) +2(2*5)
= 2 * 55 + 2 * 22 + 2 * 10
= (110 + 44 + 20) square cm
Which gives you 174 square centimetres.
