Answer:

The ratio of sanstone to marble is... 141414 : 333

All you have to do is look at how much sandstone Dean has and how much marble he has, then put the amount of sandstone infront of the amount of marble because in the question it says what is the ratio of sandstone to marble and you see that sandstone is first.

Hope this helps! :)

__ __ Calcula (a+b), si la suma de los complementos aritmeticos de ab y ba es 24

IceJOKER [234]

Respuesta:

dieciséis

Explicación paso a paso:

100-ab - - - - (1)

100-ba - - - - (2)

Sumando (1) y (2) sumas hasta 24

100-ab + 100-ba = 24

100 + 100 - ab - ba = 24

200- (10a + b) - (10b + a) = 24

200-10a-b-10b-a = 24

200-24 = 10a + 10b + b + a

176 = 11a + 11b

176 = 11 (a + b)

176/11 = a + b

16 = (a + b)

Solve by elimination:

LenaWriter [7]

Answer: $(4, 3)$

Step-by-step explanation:

1) Multiply the first equation by 3,and multiply the second equation by -5: $3(2x-5y=-7)$ , $-5(5x-3y=11)$

2) Simplify: $6x-15y=-21$ , $-25x+15y=-55$

3) Add the equations to eliminate $y$ : $-19x=-76$

4) Divide both sides by $-19$ : $\frac{-19x}{19} =\frac{-76}{-19}$

5) Simplify: $x=4$

6) Substitute 4 for x in $2x-5y=-7$ : $(2)(4)-5y=-7$

7) Simplify: $-5y+8=-7$

8) Subtract $8$ on both sides of the equation: $-5y+8-8=-7-8$

9) Divide both sides by $-5$ : $\frac{-5y}{-5} =\frac{-15}{-5}$

10) Simplify: $y=3$

11) Write point: $(4, 3)$
