Help ASAP (Math) will give brainiest and points!!
nordsb [41]

Answer:

2.17 \times 10^{-1}

Step-by-step explanation:

(7 \times 10 ^{-6}) + 0.26 - (5 \times 10^{-2}) = \frac{7}{10^3} + \frac{26}{10^2}-\frac{5}{10^2}

                                              = \frac{7 + (26 \times 10) - ( 5 \times 10)}{10^3}\\\\=\frac{7 + 260 - 50 }{10^3}\\\\=\frac{217}{10^3}\\\\= 2.17 \times 10^2 \times 10^{-3}\\\\= 2.17 \times 10^{-1}

Solve the equation 7/z-1 = 9/z+4
algol [13]

Answer:

z is equal to 18.5

Step-by-step explanation:

When an equation is in the format a/b = c/d, the quickest way to simplify it is to cross multiply.  Each side is multiplied by the other sides denominator, eliminating the division:

\frac{7}{z-1} = \frac{9}{z + 4}\\7(z + 4) = 9(z - 1)\\7z + 28 = 9z - 9\\7z - 9z = -9 - 28\\-2z = -37\\z = 37/2\\z = 18.5

So z is equal to 18.5

Se van a transportar sacos que contienen 50 kg de azúcar cada uno, el camión que se va utilizar para el transporte de los sacos
LekaFEV [45]

Function: 50x=8000 (maximum number of packages: 160)

Step-by-step explanation:

In this problem, we have:

C=8 ton = 8000 kg is the capacity of the truck (the amount of mass that can be stored in the truck)

p = 50 kg is the mass of each package that need to be stored in the truck

We can find the number of packages that can be transported as follows: calling this number x, the total mass of x packages is

p\cdot x

This amount should be at most equal to the capacity of the truck, therefore:

px=c

And substituting the numbers,

50x=8000

And solving the equation, we can found the number of packages that can fit into the truck:

x=\frac{8000}{50}=160
