Answer:
b and d
Step-by-step explanation:
there is two answers
the equation,
3u+40+2u=6u-30-u
can be solved by the following steps.
3u+40+2u=6u-30-u
+2u
5u+40=6u-30-u
-5u
40=u-30-u
+30
70=u-u
70=0
This equation has no solution
The width can be x.
so it means that the length is 2x
the equation would be
2(x+2x)=24 inches
2x+4x= 24
6x= 24
x=4 (this is the width, so the length will be 8 inches)
the area will be 4 times 8 = 32
Answer:
Exact answer not possible: See below.
Step-by-step explanation:
The total that Tammy would pay is the sum of 2A and 5B, where A and B are the number of candies costing $2 and $5, respectively. Therefore:
2A + 2B = Total Spent
We are told Tammy spent <u>at least</u> $75, which can be written as "Total Spent > $75."
The equation becomes 2A + 5B > 75
Rearranging:
2A + 5B > 75
2A > 75 - 5B
A > (75 - 5B)/2
To find the maximum of the candy A bought, one can try different values of A and B that result in a total of at least $75. If the amount spent were $75 exactly, a solution would be 35 A (for $70), leaving $5 for 1 candy B. But we don't know the exact amount. The problems states "at least $75." As far as we know, Tammy may have spent $105, $405, $1,005, or even $4,005 (200 A and 1 B). One cannot pick a maximum simply since the maximum spent is not defined. The next possible value above $75 would be $77, which represents 36 A and 1 B candies.
Any number above 1 gets greater, below 1 smaller (when above 0), while 1 itself remains the same. Negative numbers are more unpredictable.
