Solve the multiplication problem. 6.7 x (-2.3) round to the hundreth.

-15.41

Step-by-step explanation:

6.7 * (-2.3) =

Lets break it into parts

6.7 * .3 = 2.01

6.7 * 2 = 13.4

Add them together

13.4+ 2.01

15.41

A positive times a negative is a negative

-15.41

The answer only has digits to the hundredths place, so no rounding is required.

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!

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
