When m is an integer, the solution of the equation 12mx − 53 = 12 (x − 43) is a positive integer?

When m is an integer, the solution of the equation 12mx − 53 = 12 (x − 43) is a positive integer?

If we solve the equation 12mx − 53 = 12 (x − 43), remove the denominator, we get 3mx-10 = 3 (x-43), remove the bracket, we get 3mx-10 = 3x-4, transfer the term and merge the similar terms, we get x (m-1) = 2, the coefficient is 1, we get x = 2m − 1, ∵ the solution of the equation is a positive integer, ∵ x > 0 and is a positive integer, ∵ 2m − 1 > 0 and M is a positive integer, ∵ M-1 is a positive divisor of 2, that is, M-1 = 1 or 2, ∵ M = 2 or 3

It is known that in △ ABC, ab = 10, AC = 7, ad is the angular bisector, cm ⊥ ad is in M, and N is the midpoint of BC. Find the length of Mn

Extend cm to intersect AB at e, ∵ am ⊥ cm, ad is the angular bisector of ∠ BAC, ≌ ame = ∠ AMC = 90 ° and ∠ EAM = ∠ cam. In △ EAM and △ cam, ≌ EAM ≌ cam (ASA), ≌ cm = me, AE = AC = 7, ≂ n is the midpoint of BC, ≌ Mn = 12be = 12 (ab-ae) = 12 × (10-7) = 1.5

The sum of numerator and denominator of a fraction is 67. If you add 5 to each numerator and denominator, it can be reduced to 2 / 2. What is the original fraction?

If we don't add 5 to each numerator and denominator, it can be reduced to two parts
After adding 5 to each numerator and denominator, the sum of numerator and denominator is 67 + 5 * 2 = 77
After simplification, the numerator is 2 and the denominator is only one step

The predicate verb form of uncountable nouns modified by quantifiers

It depends on whether the quantifiers are countable, the countable singular and plural forms, the form of predicate verb and the tense of predicate verb

(3a + 5b) - {9A - [6a-2a (3b-4a)]} where a = 5 and 2 / 3, B = 10 and 2 / 3

(3a+5b)-{9a-[6a-2a(3b-4a)]}
=3a+5b-[9a-(6a-6ab+8a²)]
=3a+5b-(3a+6ab-8a²)
=5b-6ab+8a²
=160/3-5×17/3×32/3+8×(17/3)²
=72/9
=8
