Ineed ! 1)solve the equation for x. -6x + 8x = -46 a) -23 b) 3.2 c) 12 d) 16 2)what is the value of w? w + 3/4 = w - 2/2 a) 7 b) 9 c) 11 d) 13 3)solve for x. 2x + 16 = 3(x - 9) a) -43 b) -25 c) 0 d) 43 4)hayley begins solving this problem by combining like terms. 3x + 5x = 10 which problem begins the same way? a) 5x = 20 b) 2(x + 5) = 20 c) x/4 = 30 d) 4x − 2x = 10 5)solve for x. -3x + 4 = -8 6)what is the first operation used in solving this equation? 2x + 5 = 10 a) addition b) division c) multiplication d) subtraction 7) 2(x + 7) + 3x = 12 the first step in solving this equation for x uses the property. a) identity b) associative c) commutative d) distributive 8)it is given that 2(3 + x) = 6 + 2x. this is an example of the property. a) associative b) commutative c) distributive d) identity 9)solve. x + 3/5=2 a) -5 b) -3 c) 7 d) 13 10)solve. 4 - 2x = 10 a) -7 b) -3 c) 0 d) 3

The first one is A, the third is D, the fourth is D, the fifth is 4, the sixth is D, the seventh is D, the tenth is D. Sorry I couldn't do all but some.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
