3s + 4j = 360
1s + 3j = 220
This one we can solve using substitution, in that
s + 3j = 220 implies s = 220 - 3j (subtract 3j from each side).
Now substitute into the first equation:
3(220 - 3j) + 4j = 360. Solve for jackets.
660 - 9j + 4j = 360 [Distributive property]
660 - 5j = 360 [Add -9j + 4j]
Subtract 360 from each side, and add 5j to each side.
660 - 360 - 5j + 5j = 360 - 360 + 5j
300 = 5j
Divide each side by 5.
$60 = price of a jacket.
Three of these plus a shirt runs $220.
3(60) = 180
180 + s = 220
180 - 180 + s = 220 - 180 [Subtract 180 from each side]
s = 40
Now we double check.
3(40) + 4 (60) = 120 + 240 = 360. This satisfies the first equation.
We could check the second one too, but I'm satisfied.
I have really know idea at all I'm so sorry this doesn't help
Answer:
The value of a decimal becomes clearer when the place value is spoken or written as the number it names. For example, 0.1 makes more sense if it is read as “one-tenth” rather than “zero point one.”
Step-by-step explanation:
LOGIC....Lol
I pooped mysels so can’t figure it out
Hello! So, 11/2 cups is simplified as 5 1/2 cups. In order to find out how many 1/8 cups Jenn will need to scoop, all you have to do is divide each number by 1/8. When you divide fractions, you keep the first fraction the same, change division into multiplication, and flip the second fraction over into it's reciprocal. So 2 / 1/8 becomes 2/1 * 8/1. With that being said, if you solve each of them correctly, here are your answers for the number of 1/8 cups needed.
Water: 16
Brown Rice: 44
Jenn willl have to use the 1/8 scoop to get water 16 times and the 1/8 scoop to get brown rice 44 times.
