Please help me and pls answer all of them. I really need help... Plssssss

Answers

Answer:

Step-by-step explanation:

Ok, so if there is no number in front of a variable (the letters), there is always a one. So you multiply them like this:

7 x 1b x 4 x 1a x 2 = 56ba

1c x 5 x 1b x 4 x 1a = 20cba

Since there is only a 1 in front of the variables, you can basically just multiply the numbers without variables and then mutiply that times one. Don't forget to add the variables into the answer.

6 x 1p x 4 x 5 x 1w = 120pw

1t x 2 x 1t x 1s = [tex]2t^{2} s[/tex]

Y=2x+19



I could be wrong
y = 4(x) + 7 - since the multiples of x are increasing at a lesser rate than the ones of y, it shows that x needs to be multiplied by a higher value. you could find the value x by plugging in different values <13, then find a common number to add that will give you the y output.
