5s + 5l = 155, 10s + 12l = 346
Solve for s in the first equation.
5s = 155 - 5l
s = 31 - l
Substitute s into the second equation.
10(31 - l) + 12l = 346
310 - 10l + 12l = 346
310 + 2l = 346
2l = 36
l = 18
Substitute l into the first equation.
5s + 5(18) = 155
5s + 90 = 155
5s = 65
s = 13
s = 13, l = 18
Answer:
-g/3+1/3
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
Let a = number of balls in bag A.
Let b = number of balls in bag B.
a = 1.2b
a - 5 = b + 5
1.2b - 5 = b + 5
0.2b = 10
b = 50
Answer: 50
To write algebraic expressions
to model quantities is you base the algebraic expressions or mathematical
values declared in words by the manner of how the sentence illustrates the said
problem. For example, one minus a number is the difference of zero shall be
1.
1 – n = 0.
Other same examples, John bought 25 apples while Julia bought only
15 from the market. If Niccole bought twice as much as Julia’s, how many was
Niccole’s apples?
<span><span>
1.
</span>You state
the problem by the sequence of the said problem and understanding the possible
structure.</span>
<span><span>
2.
</span>Solution
will be</span>
Julia = 15 apples
Niccole = 2Julia
Hence,
2Julia = 2(15) = 30 apples.
I think the answer may be C
