There are 155 sea urchins that are being collected for a few large aquarium displays. If a tank can hold no more than 50 urchins, how many tanks will be at their urchin limit, and how many urchins will be leftover?

Number of tanks full: ?

Urchins left over: ?

hello,

155 ÷ 50 = 3,1

so, there are 3 tanks full and 5 urchins left over.

3 × 50 + 5

150 + 5 = 155

answer: 370

step-by-step explanation:

remember use pemdas! there are no parentheses or exponents so lets move onto the first part of the equation: multiplication and division. first, lets break the first part of the equation up into something easier using the distributive property. 28 * 12= (20 *12) + (8*12) you know that 20*12 is 240 and 8*12 is 96. add them and you get 336. then, lets solve the last part of the equation (the last part of pemdas is addition and subtraction). 336 plus 34 is 370. hope this !

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
