Answer:
Step-by-step explanation:
-6.25x > -38 3/4
-6.25x > -155/4
Multiply by (-4)
25x > 155
divide by 25,
x > 155/25
x > 31/5
x > 6.2
Answer:
19
Step-by-step explanation:
ok is this just a joke?
nine plus ten
9 + 10 = 19
Step-by-step explanation:
(180-x)-40=X
140 -x=X
140= 2x
x=140/2
x=70
the answer is 70 degree
12
x 10
______
120
it's pretty simply,sorry if I got it wrong,i'm kinda tired<span />
Answer:
see below
Step-by-step explanation:
Consider the rule y = 5x + 7.
a. How many tiles are in Figure 0?
In figure 0, we let x=0
y = 5*0+7 = 0+7 = 7
b. Which figure has 37 tiles?
This means y = 37
37 = 5x+7
Subtract 7 from each side
37-7 = 5x+7-7
30 = 5x
Divide by 5
30/5 = 5x/5
6 =x
Figure 6 has 37 tiles
c. In the equation y = mx + b, what do the letters m and b represent?
m is the slope or how much it is increasing each time x increases by 1 and b is how much we start with when x =0
