Lindsay and Lorraine are trying to match the jump rope world record. Together, they need to jump 48 times in a row. Lindsay has

Sunny_sXe [5.5K]

Answer: 21

Step-by-step explanation:

Given : Lindsay and Lorraine are trying to match the jump rope world record.

Number of jumps they need to jump together in a row = 48

Lindsay has gotten 14 jumps in a row, and Lorraine has gotten 13.

Total jumps = 14+13=27

Let 'j' be the number of more jumps they need to match the record.

j= Total jumps needed - Total jumps they already gotten

⇒ j= 48-27

⇒ j= 21

Hence, they need 21 more jumps to match the record.

If m = 5 and n = -2, evaluate 3m - 4n and n2 - m and find the product of the two expressions.

ddd [48]

Hence the correct answer is C) -23

Further explanation:

We have to put the values of m and n into both expression first separately and then multiply the answers.

Given expressions are:

$Exp\ 1:3m-4n\\Exp\ 2: n^2-m$

The values are:

$m=5\\n=-2$

Putting the values in expression 1:

$3m-4n\\=3(5)-4(-2)\\=15+8\\=23$

Putting the values of m and n in second expression

$n^2-m\\=(-2)^2-5\\=4-5\\=-1$

Multiplying both expressions:

$(3m-4n)(n^2-m)=23* (-1)=-23$

Hence the correct answer is C) -23
