74-17= 57 because if you subtract 10 from 74, it would be 64, then you need to subtract 7 from 64, which gives you 57.
9+7=16 because 10+7 would be 17, but since 9 is one less than 10, you need to subtract one from 17, which gives you 16.
17+(-30)=(-13) because adding 17 to -30 only brings up -30 to -13, and -30<-13.
-41+24=-17. Same reason as question 3, only different numbers.
-36+(-7)=-43 because adding two negatives together is like subtracting two positives from each other.
14+64=78 because adding 10 to 64 is 74 and 74+4=78.
-53-42=-95 because when you subtract a positive from a negative, it decreases the number even more.
-17-(-62)=45 because -62 is less than -17 and it is being subtracted from -17 so the answer becomes positive.
Hope this helps :)
5/3x = ? ; where x = 90
90/1 times 5/3
cross simplification
now it's 30/1 times 5/1 i divided the numerator of the first fraction and the denominator of the second fraction by 3
now it is 5 times 30
so... 5/3 of a 90 degree angle is 150 degrees
Answer:
$1300
Step-by-step explanation:
52/5 = 10.4
$125 * 10.4 = $1300
or another way
125/5 = $25/week
$25 week * 52 weeks = $1300
My solution to the problem is as follows:
sqrt(294) - sqrt(24) + sqrt(54)
= sqrt(49 * 6) - sqrt(4 * 6) + sqrt(9 * 6)
= sqrt(49)*sqrt(6) - sqrt(4)*sqrt(6) + sqrt(9)*sqrt(6)
= 7*sqrt(6) - 2*sqrt(6) + 3*sqrt(6)
= (7 - 2 + 3)*sqrt(6)
= 8*sqrt(6)
= sqrt(64)*sqrt(6)
<span>= sqrt(384)
= 8*sqrt(6)
Therefore, the answer is letter B, 8 square root of 6

I hope my answer has come to your help. God bless and have a nice day ahead!
