Answer:
x = 3
y = 0
z = 8
Step-by-step explanation:
a) 3x + 3y - z = 1
b) z = 8
c) -x -3y + 2z = 13
a) 3x + 3y - 8 = 1 (substitution)
a) 3x + 3y = 9
c) - x - 3y + 2(8) = 13 (substitution)
c) -x - 3y + 16 = 13
c) -x - 3y = -3
(3x + 3y = 9) + (-x -3y = -3)
= 2x = 6
x = 3
a) 3(3) + 3y - 8 = 1
9 + 3y - 8 = 1
y = (1 -9 + 8)/3
y = 0
Answer: 315.3 cm / 3.153 meters
Step-by-step explanation:
3,4 meters = 340 cm
340 cm - 24.7 cm = 315.3 cm
If the slope is 6/11 then, in y=mx+b form, m will be 6/11. When you multiply 6/11 and -1 you get -6/11. To get the y (-6), you have to add -60/11. So in, y=mx+b form the equation is y=6/11x+(-60/11). To make it standard form, you add negative 6/11x to both sides and then multiply by 11 to get rid of the fractions. So therefore the equation would be:
-6x + 11y = - 60
Answer:
1497 - 202
Step-by-step explanation:
The question is saying that the Las Vegas trip was longer so we know to put that first in the expression
we can also tell that the question is asking us for the difference (aka subtraction) between the two trip by the key words <em>how much longer</em>
and then it tells us that we are finding the difference between Las Vegas and Cheyenne so we know to use those two numbers
that is how we come up with the expression 1497 - 202
