Four consecutive integers are four numbers in a row, with a difference of one between each of them.
x= first integer
x+1= second integer
x+2= third integer
x+3= fourth integer
sum= add
increased by 10= add 10
the result is= equal sign
6 greater than= add 6
4 times= multiply
EQUATION
(x + x + 2) + 10= (4(x + 3)) + 6
combine like terms on the left side
2x + 12= (4(x + 3)) + 6
multiply 4 by terms in parentheses
2x + 12= 4x + 12 + 6
combine like terms on right side
2x + 12= 4x + 18
subtract 4x from both sides
-2x + 12= 18
subtract 12 from both sides
-2x= 6
divide both sides by -2
x= -3 first integer
x+1= -2 second integer
x+2= -1 third integer
x+3= 0 fourth integer
ANSWER: The four consecutive integers are -3, -2, -1 and 0.
Hope this helps! :)
Mary has 20 liters of paint mixed white:blue in the ratio 2:3. So two fifths of that paint is white and three fifths is blue. So that's 8 liters white, 12 liters blue.
We want to add paint to get white:blue = 1:7. Clearly we need to add blue. We have our 8 liters of white, so we need a total of 7(8)=56 liters of blue. We already have 12, so we have to add 56-12=44 liters of blue paint:
Answer: Add 44 liters blue
Answer: 
.
Step-by-step explanation:
Given : Sample size : n= 64 , the sample is a large sample (n>30), so we can apply z-test.
Sample mean = 
Standard deviation : 
Level of confidence:
Then, critical z-value =
The confidence interval to estimate the population mean is given by :_
Hence, the 95% confidence interval to estimate the population mean can be computed as .
2.4 cause 0.24×10=2.4
if you move the decimal one place to theleft you'll get 2.4
