Steve has 84 basketball cards,which is 7 times as many as claire.Claire buys 63 more cards,if b is the number of cards that claire has now then what is the value of b

Value of B= 75  Basketball cards

Step-by-step explanation:

STEP 1

let number of cards Steve has be =a

let number of cards Claire has be =b

STEP 2

Steve has a= 84 basketball cards

Claire has 7 times less than Steve = 84 /7 = 12=b

STEP 3

if Claire buys 63 more cards

The present value of card Clare now has = 12 +63 = 75 basket ball cards=b

The correct option is;

Callie multiplied incorrectly

Step-by-step explanation:

Here we have 0.42 × 4.73 = 1.9866 then

1.9866 + 29.4 + 168 = 199.3866

Therefore, from the question, we had 0.42 × 4.73 = 1.26 which is incorrect, meaning that Callie multiplied incorrectly

Apparently, Callie multiplied as follows;

0.42 × 3 = 1.26 but what was in the question was

0.42 × 4.73 which is equal to 1.9866.
