You know how to use addition and subtraction right? There is no difference when it has the same variable. For instance, 4 + 4 = 8, what does 4x + 4x =? 4x + 4x = 8x. You simply added an x at the end, that's all.
9 - 7 = 2
9m - 7m = 2m
2 + 2 = 4
2m + 2m = 4m
For your example, the answer is 4m because of this.
When the variables are different, for instance, 4x + 3y = 5, you would try to get it into a formula structure, but that's something else.
Answer:
see explanation
Step-by-step explanation:
The corresponding angles are
∠ B = ∠ L
∠ C = ∠ M
∠ D = ∠ J
∠ E = ∠ K
----------------------------
The corresponding sides are
BC = LM
CD = MJ
DE = JK
EB = KL
Thus BCDE ≅ LMJK
Answer:
n=8
Step-by-step explanation:
2(5-6n)=10n-166
1) Distribute the 2 to 5 and -6n:
10-12n=10n-166
2) Add 166 to both sides:
176-12n=10n
3) Add 12n to both sides:
176=22n
4) Divide both sides by 22:
n=8
64 + 0 + 0 + 8 + 0 + 0 + 1 = 73. So, 73 is the decimal equivalent of the binary number 1001001.
210 = 4/5 (This means that 4 out of five people (210 people) are a teenager)
Then you divide 210 by the numerator to get 1/5 people:
210 / 4 = 52.5
Then you can multiply the 1/5 people (52.5) by 5 to get 5/5:
52.5 * 5 = 262.5 (rounded to 262)
Thus the maximum amount of teenagers in Geotown is 262.
Hope this helps! :)
