First set up the equation to find answer: y=7-x. Then add it to the variable. 3x-1(7-x)=1. So that makes it 3x+-7+-1=1. Add like terms -7+-1=-8, so 3x+-8=1. Now to find x just switch the 8 to the other side. So you end up with 3x=9 since when you take away a number from one side you need to use the opposite value so adding 8 to -8 will cancel it out, then add it to the other, then just divide. 9/3=3, from here just substitute to find y. y=7+3. y=10.
The answer is x=2 and y=5. I hope I helped!
Answer:
8
Step-by-step explanation:
dog=3x
cat=x
3x+x=32
4x=32
4/4
32/4
x=8
3(8)=24
x=8
So she trained 24 dogs and 8 cats
Answer:
The answer is B hope this helps
Answer:
Y = mx + b
y = how far up
x = how far along
m = Slope or Gradient (how steep the line is)
b = value of y when x=0
Answer:
f(n) = 74 + 11(n - 1)
<u>For the 7th term</u>
n = 7
f(7) = 74 + 11(7 - 1)
= 74 + 11(6)
= 74 + 66
<h2>= 140</h2>
<u>For</u><u> </u><u>the</u><u> </u><u>8</u><u>t</u><u>h</u><u> </u><u>ter</u><u>m</u>
n = 8
f(8) = 74 + 11( 8 - 1)
= 74 + 11(7)
= 74 + 77
<h2 /><h2>= 151</h2>
Hope this helps you
