Jorge needs two different kinds of concrete: quick drying and slow drying. The quick-drying concrete mix calls for 2 pounds of dry cement, and the
quick-drying concrete and 3 times more slow-drying concrete than the mixes make.
slow-drying concrete mix calls for 1 pounds of dry cement. He needs 5 times more
2. How many pounds of dry cement mix will he need?
- Use the properties of real numbers to show how Jorge could compute this amount
mentally. Justify each step.

mr. graef told us it is 13 pints

step-by-step explanation:

160

i hope i

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

the rocket cannot penetrate the ground, in a contextual sense, therefore the roots of this equation should be the domain of this function. i'll let you find the roots of this quadratic equation (hint: use the quadratic formula:
