5×67=
a. (67×10)÷2
b. (67x2)+(67×2)
c. (6 ×7)×5
d.(5×6)+(5×7)

a).

= (67×10)÷2

= 670 ÷ 2

= 335

Explanation:

a).

= (67×10)÷2

= 670 ÷ 2

= 335

So, 5×67 = (67×10)÷2

=> 335 = 335

b).

= (67x2)+(67×2)

= 134 × 134

= 268

So, 5×67 ≠ (67x2)+(67×2)

=> 268 ≠ 335

c).

= (6 ×7)×5

= 42 × 5

= 210

So, 5×67 ≠ (6×7)×5

=> 210 ≠ 335

d).

= (5×6)+(5×7)

= 30 + 35

= 65

So, 5×67 ≠ (5×6)+(5×7)

=> 65 ≠ 335

Hence, (a) is the correct answer.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
