This is the same as any math problem you may have solved before.
First, start by isolating the x on one side. I will choose to keep the coefficient positive, so I will add x to both sides.
6>2x+2
Subtract 2
4>2x
Divide by 2
2>x
Or
x<2
Answer:

Step-by-step explanation:
9/4=2.25
Answer:
a)14 or b)74
Step-by-step explanation:
I'm assuming the question is how many combinations are there.
A) If toppings can't stack it would be 14, since there are 6 toppings for 2 pies and also you can go without toppings. or *2
B) If toppings can stack, then there can be 74 from being able to stack 6 toppings on one pizza and then two pizzas without it or (6^2)*2+2
Answer:
x=64
Step-by-step explanation:
* change equivalent to to = *
now we have x² - 16x + x = (x-8)²
step 1 simplify both sides
(x)²=x²
-8x*2=16x
8=64
-16x + x = 15x
now we have x² -15x = x² - 16x + 64
step 2 subtract x² from each side
x² -x² = 0
x² - x² cancels out
now we have -15x = -16x + 64
step 3 add 16x to each side
-15x + 16x = x
-16x + 16x cancels out
we're left with x = 64
Answer:
train A=38mph train B=44mph
Step-by-step explanation:
Setting up a table:
s t d
A x 190/x 190
B x+6 220/x+6 220
Train A was 6mph slower as shown in the table, so to make it easier, train a is identified as x, train b would be x+6
Their distances are put in their respective column.
You find time from distance divided by speed.
So time would be written as such.
Since you know they take the same amount of time, for the equation, you connect them with an equal sign. Cross multiply to something like:
190(x+6)=220x
190x+1140=220x
1140=30x
x=38
You plug this in and get the speed for train A as 38, and train B as 44.
Hope this helps ^^
