Answer: p= $8 s= $2.50
Step-by-step explanation:
3p + 4s = 34 and 3p + 7s= 41.50
Since the number of pizzas DIDNT change between these two equations, we can use the total of the second equation to help us find the price of one sandwich.
41.50 - 34 = $7.5 for 3 sandwiches (7s-4s)
So how much is one sandwich? 7.50/3 = $2.50 for each sandwich
now that we know s, it’ll be much easier finding p. We can use one equation to find p.
3p + 4(2.5) = 34 (Solve algebraically)
3p + 10 = 34
- 10 | -10
3p = 24
3p/3 = 24/3
p = $8. Now you can check by substituting the variables!
Answer:
y - 4 = 3(x- (-1) ---> y-4 = 3(x+1)
Step-by-step explanation:
y - 4 = 3(x + 1)
y - 4 = 3x + 3
y = 3x + 7
then plug in (-1,4)
4 = 3(-1) + 7
4 = -3 + 7
4 = 4
Point slope form looks like:
y - y₁ = m(x - x₁)

11 times 7 plus 6 times 6 equals
Answer:
x = -6
Step-by-step explanation:
Step 1: Write out equation
-2 = x + 4
Step 2: Subtract 4 on both sides
-2 - 4 = x + 4 - 4
-6 = x
Step 3: Rewrite
x = -6
Consider the expression This expression is equivalent to the expression
This expression contains two factors:
1 factor:
2 factor:
The second factor does not contain x (is not depending on x), then the expression is the product of x and a factor not depending on x.
