Tell whether the equation is true. Justify your answer.24x3+(15-7)÷2=8x9+12÷2

1 answer:

4 0

False
Because the left side comes out to a sum of 40 while 15-7 equals 8 and 24 times 3 equals 72 72 plus 8 equals 80 divided by 2 equals 40 and 8 times 9 equals 72 plus 6 equals 78 plus 6 equals 84

Find 3 consecutive even integers if their sum decreased by 10 equals -22

Orlov [11]

Three consecutive even integers can be represented by x, (x+2), and (x+4).

(x + (x + 2) + (x + 4)) - 10 = -22 Get rid of the parentheses
x + x + 2 + x + 4 - 10 = -22 Combine like terms (x + x + x) and (2 + 4 - 10)
3x - 4 = -22 Add 4 to both sides
3x = -18 Divide
x = -6
Check you work.

x = -6
x + 2 = -4
x + 4 = -2

(-6 - 4 - 2) - 10 = 22
-12 - 10 = -22

So, your three integers are -6, -4, and -2 .

You roll a 10 sided die. What is the probability of rolling a odd number and less than 4?

zzz [600]

Answer:

Probability of it being odd would be one half, and for less than four would be 2/10

Step-by-step explanation: Since it can only be odd the chance for it landing on odd is half.

then since it has to be lower than 4, and since there's only 1, and 3 that are odd and lower than four you would only have a 20 perecent chance of it landing on 1 or 3
