Answer:
D
Step-by-step explanation:
So if Arturo's family hires 3 painters for $50 an hour each, how much do they spend?
X= Charge for number of number of hours
Now let's say that each of the painters worked only <u>one </u> hour each.
That would be take a long time to add up so you multiply.
$50 x 3
In other words it's $50 + $50 + $50.
$50 x 3 = $150
Now X stands for the amount of money paid to each artist. In this case, X= $50. So we already figured out X. X is $50. It is a mistake to add the X at the end of the answer because X is already there in a numerical form. So the answer is D, $150.
Answer:
B
Step-by-step explanation:
The goal of this equation is to solve for x. So, we can start by combining like terms.
(16x) and (5x) are like terms, so we would subtract (5x) over to the other side.
131 + 16x -5x = -331 + 5x - 5x
131 + 11x = -331
Then, we can combine the other like terms, which would be (131) and (-331). Subtract 131 on both sides.
131 - 131 + 11x = -331 - 131
11x = -462
Now, we need to divide the number before x, or the coefficient.
11x/11 = -462/11
x = -42
We have to find the probability of not getting odd, whole rolling a 6 sided die ~
Actually dices have 3 odd numbers (1 , 3 , 5) and 3 non - odd numbers (2 , 4 ,6)
When we roll a dice, we may get any of the six numbers, so total possible outcomes are 6
and, The number of Favorable outcomes is 3, i.e non - odd numbers.
<span>-3(1+6r)=14-r
-3 - 18r = 14 - r ...expand by using distributive property
-3 -17r = 14 ...add (r) to both sides
-17r = 17 ...add (3) to both sides
r = -1 ....divide both sides by (-17)</span>
