Answer:
Yes; James got 76 answers correct
Step-by-step explanation:
Round 1: 50 x 0.8 = 40
Round 2: 40 x 0.75 = 30
Round 3: 30 x 0.2 = 6
40 + 30 + 6 = 76
It would be 22/125.
You'd convert the fraction by placing the decimal number over a power of 10.
Answer:so that’s a interior triangle so the mean your 2 points in the inside and the equation on the outside.
X=6
Step-by-step explanation:
(8x-4)+(3x+17)=(17x-23)
Combined our alike terms on the left side of the equation. So 8x+3x and -4+17.
11x+13=17x-23
Now this is what the equation should look like after combining ur alike terms.
11x+13=17x-23
-11x. -11x.
now u take the lowest x which is 11x and mince that from 17x but u only mince if it’s a positive but is it’s a negative u add it.
13=6x-23 so if u moved the x on the right side u move non variable number to the left but if u moved the x to the left u move the non variable number to the right so in this case the non variable number would be -23 so now u add 23 on both sides.
36=6x and now u just divide the 36 by 6 and remember to always divide by the x
Now the answer is x=6
T= Tina's age
t+2= second child
t+4= third child
36= age of all children
Add the ages of all children equal to 36 years. Add 2 to each age because there is 2 years age difference between each child.
t + (t+2) + (t+4)= 36
combine like terms
3t + 6= 36
subtract 6 from both sides
3t= 30
divide both sides by 3
t= 10 Tina's age
t+2= 12
(10)+2= 12 age of second child
t+4= 14
(10)+4= 14 age of third child
ANSWER: The formula that will calculate Tina's age is t + (t+2) + (t+4)= 36.
Hope this helps! :)
The answer is I believe, .0416 repeating
