Answer:
x = 2
y = 7
Step-by-step explanation:
5x+2y=24 -------------->equ 1
8x+2y=30 -----------> equ 2
equ 1 - equ 2 =====> -3x = - 6
x = -6 / -3 = 2
x = 2
Put x = 2 in equ 1,
5*2 + 2y = 24
10 + 2y = 24
2y = 24 - 10
2y = 14
y = 14/2
y = 7
Is equal to 19 u add the 9 plus the ten so u get 19
The numbers are best written as,
(1.2 x 10⁻²)(3.65 x 10⁸)
If we multiply the bases of the scientific notations, we get an answer of 4.38. There exists a rule which states that for exponents of the same number which are multiplied, we add up the exponents. Thus, our final answer would be,
4.38 x 10⁶
