So the equation would be 4x+x=30. So since they have the same variable, x and 4x, you add them together to get 5x=30. Then you divide by both sides and get x=6. So there are 6 spaniels.
Answer:
x=3
y=11
Step-by-step explanation:
y = 3x + 2 equation 1
y = 7x - 10 equation 2
using equation 1 in equation 2 we have:
3x + 2 = 7x - 10
2=7x - 3x -10
2 = 4x -10
2+10 = 4x
12= 4x
12/4 = x
we have:
x= 3
using equation 1:
y = 3x + 2
y= 3(3)+2
y=9+2
y=11
Answer:
b(n) = -23 + 18n
Step-by-step explanation:
NOTE - This is an arithmetic sequence, so each number is increasing by addition. If you were in a geometric sequence, however, you'd be multiplying. This means that the explicit formula for the geometric sequence you'll be learning later on will be different.
The formula for explicit formula is b(n)=b(1)+d(n-1). The variable d represents the common difference and the a is whatever number of the term you are using.
Since you have b(1), you look at what your first term is. Plug -5 into a(1).
To find your common difference, find 13-(-5). This is 18, and adding it to the others you can see that it continues.
So, plugging in what you have so far it looks like b(n) = -5 + 18(n - 1)
All we need to do now is simplify.
1. Distribute: -5 + 18n - 18
2. Add like terms: -23 + 18n
Hope this helped and made sense lol.
You are finding the perimeter, which has double of each side length given.
Note: P = perimeter
2(5x - 1) + 2(2x + 1) = P
Distribute 2 to each monomial in the given parenthesis
2(5x - 1) = 10x - 2
2(2x + 1) = 4x + 2
10x - 2 + 4x + 2 = P
combine like terms.
P = 10x + 4x - 2 + 2
P = 14x
C) 14x, is your answer
hope this helps
