Answer:
Lina's solution is correct because it expresses 126 as a product of prime factors.
Step-by-step explanation:
Prime factorization can be defined as a methodology of breaking down an original number down into the set of prime numbers which when multiplied together give us the original number.
Prime factorization makes use of a factor tree
The number we are to carry out prime factorization on is 126
126
/\
3 42
/\
6 7
/\
2 3
The Prime Factorization is:
2 x 3 x 3 x 7
Hence, Lina's factor tree of 126. 126 branches to 3 and 42. 42 branches to 6 and 7. 6 branches to 2 and 3. The equation is 126
= 2 times 3 squared times 7.
Is correct.
Answer:
x = 23
Step-by-step explanation:
Exterior angles equals the sum of opposite interior angles.
2x+ 3 + 51 = 100
Combine like terms.
2x + 54 = 100 {Subtract 54 from both sides}
2x = 100 - 54
2x = 46 {Divide both sides by 2}
x = 46/2
x = 23
Answer:
29. A 30. $7.50 31. 1(2) 1(3) 3(4) 1(5) 1(6) 1(7)
Step-by-step explanation:
29.
multiply $2500 by the percentage (ie. 24%) that is how to get the amount.
30.
if 4 boxes equal $5.00 and Jeniffer has 6 then 4 of her 6 equal 5.00 and half of five is 2.50 which mean the 2 remaining would be added and would equal $7.50
31.
you add 1 dot to the top of the number for every time that one number shows up (example: if you have 3 2's, then you add 3 dots to the top of the number 2)

Answer:
$25.50
Step-by-step explanation:
So we have a 15% off coupon. We can multiply 25×.85 to find our new price.
Our total is now $21.25
Now to find the tip do $21.25 +(.2 × 21.25)
*The .2 is 20 percent of our discount price.*
We then get $25.50
