Answer:
Step-by-step explanation:
13 = 6+7
276*13 = 276*(7+6)
= 276*7 + 276 *6 {distributive property upod addition}
= 1932 + 1656
= 3588
Answer:
Only 1 pair of feet duhh and a few of the other things that are not in the same way as the same thing is true for the natives from the americas and now claim it as if it were ares to start with the same thing as the last time I was there and I was just wondering if you had any ideas on how to get a new one for the natives from the americas and now claim it as if it were ares to start with the same thing as the last time I was in there middle of school all as but it 4th 4images in a group and that will not have make of these days available until the next time week have the case or the natives time Europe and fend it will take place in a actuality for my new place job then the same time you
To find the rate in miles per hour, divide the miles by the hours.
(1 1/2 miles)/(3/5 hour) =
= 3/2 miles * (5/3 hour)
= 5/2 mph
= 2 1/2 mph
Her walking rate is 2 1/2 mph.
(4 1/2 miles) / ( 2 1/2 mph) =
= 9/2 miles / (5/2 mph)
= 9/2 * 2/5 hours
= 9/5 hours
= 1 4/5 hours
From 9:00 a.m. to 11 a.m., she has 2 hours, but she only needs 1 4/5 hours to walk, so she will make it to work on time.
Use substitution.
2p + 3(2p) = 680
2p + 6p = 680
8p = 680
p = 85
Plug in.
x = 2p
x = 2(85)
x = 170
p = 85
If you would like to solve the system of equations, you can do this using the following steps:
5p - 3r = 1 /*2
8p + 6r = 4
__________
10p - 6r = 2
<span>8p + 6r = 4
</span>__________
10p - 6r + 8p + 6r = 2 + 4
18p = 6
p = 6/18
p = 1/3
<span>5p - 3r = 1
</span>5 * 1/3 - 3r = 1
5/3 - 3r = 1
5/3 - 1 = 3r
5/3 - 3/3 = 3r
2/3 = 3r
r = 2/9
(p, r) = (1/3, 2/9)
The correct result would be <span>(1/3, 2/9)</span>.
