Answer:
Step-by-step explanation:
I guess the angles are supplementary, which means they have a sum of 180º.
11x - 15 + 5x - 13 = 180
16x -28 = 180
16x = 208
x = 13
¾ an hour is 45 minutes
So to have your answers you need to do a cross product :
45 minutes —> 2/3 of a chapter
60 minutes —> X of a chapter
((2/3) • 60) / 45
40/45 = 8/9
Answer : You read 8/9 of a chaper per hour! :)
Since the legs of the triangle are 1 and 1 the hypotenuse would be 1 also. And since squares have equal sides you know that every other side of the square are 1. The algorithm for area is base times height. So 1 times 1 is 1 unit squared.<span />
Answer:
X+7
Step-by-step explanation:
If the youngest child's age expression is X+3 then the middle child's would be x+5 and the oldest would X+7. Even numbers have a difference of 2 between them and that is why 2 is gradually added to each age expression. Hope that helps.
Ok...lets explore..
2 consecutive numbers.....2 and 3.....the LCM is 6.....2 * 3 = 6....that works
2 consecutive numbers.....3 and 4....the LCM is 12....3 * 4 = 12...that works
2 consecutive numbers.....5 and 6....the LCM is 30.....5 * 6 = 30..that works
2 consecutive numbers....1 and 2....the LCM is 2....1 * 2 = 2...that works
her theory appears to be true.
