Ann works 51/2 hours, Mary works 61/3 hours, and John works 41/4 hours. How many combined hours have they worked?

1 answer:

7 0

Combining the answers to get the sum of the hours, adding 5.5+6.3+4.25( the decimal equivalents of your fractions listed) is the equivalent of 16.05hrs. The closest answer to this would be an estimated 16.08 AKA Answr C.

Hope this helps!! (:

Bart used place value and the distributive property to rewrite the expression 6(412). His work is shown below. 6(412) = 6(400 +

egoroff_w [7]

Bart should;

Multiply 6(400), 6(10), and 6(2) ⇒ 2nd

Multiply each addend by 6 ⇒ 4th

Find the sum of (2400 + 60 + 12) ⇒ 5th

Step-by-step explanation:

Let us revise the distributive property

a(b + c) = ab + ac
a(b + c + d) = ab + ac + ad

Bart used place value and the distributive property to rewrite the

expression 6(412)

His work is shown 6(412) = 6(400 + 10 + 2)

We need to know what Bart should do to find the product

∵ 6(412) = 6(400 + 10 + 2)

- Multiply each number in the bracket by 6 in the right hand side

∴ 6(400 + 10 + 2) = (6)(400) + (6)(10) + 6(2)

∴ 6(400 + 10 + 2) = 2400 + 60 + 12

∴ He should to multiply each addend by 6 and then find the sum of

(2400 + 60 + 12)

Bart should;

Multiply 6(400), 6(10), and 6(2)

Multiply each addend by 6

Find the sum of (2400 + 60 + 12)

Myers balloons cost $1.25 each, and latex balloons cost $0.75 each. What equations can be used to find the number of each of bal

fredd [130]

We can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon for Myer

<u>SOLUTION: </u>

Given, Myers balloons cost $1.25 each, and latex balloons cost $0.75 each. We have to find what equations can be used to find the number of each of balloon in a bunch of 18 balloons that costs $19?

Let number of myers balloons be m, and number of latex balloons be n.

Then m + n = 18 ⇒ (1)

And according to given information,

$1.25 x number of myers ballons + $0.75 x number of latex balloons = $19

⇒ 1.25m + 0.75n = 19 ⇒ (2)

Hence, we can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon.

Now, (1) ⇒ m = 18 – n. substitute these values in (2)

(2) ⇒ 1.25(18 – n) + 0.75n = 19

22.5 – 1.25n + 0.75n = 19

1.25n – 0.75n = 22.5 – 19

0.5n = 3.5

n = 7

Then, m = 18 – 7 ⇒ m = 11.

So, 11 myers balloons and 7 latex balloons.
