Solve this system of linear equations. Separate
ASHA 777 [7]

Answer:

x=-17/19, y=131/19. (-17/19, 131/19).

Step-by-step explanation:

-19x=26-9

-19x=17

x=-17/19

9(-17/19)=54-9y

-153/19=54-9y

9y=54-(-153/19)

9y=54+153/19

9y=1026/19+153/19

9y=1179/19

y=(1179/19)/9

y=(1179/19)(1/9)

y=1179/171

y=131/19

Let a,b & c be the number of cookies Adrian, Bobby and Calvin baked respectively.

(a+b+c)/3 =138

(a+b)/2 =136

a+b=272

a=272-b

(b+c)/2 =125

b+c=250

c=250-b

Sub a=272-b and c=250-b into (a+b+c)/3 =138,

(a+b+c)/3 =138

[(272-b)+b+(250-b)]/3 = 138

272-b+b+250-b = 414

-b = -108

b=108

From the above,

a=272-b

=272-108

a=164

c=250-b

=250-108

c=142

∵ a=164

b=108

c=142

∴ Adrian baked 164 cookies.

Bobby baked 108 cookies.

Calvin baked 142 cookies.

Why do scientists use scientific notation<br> science
grandymaker [24]
Because it makes quantities with a lot of digits small enough that you can do math with them.

example:
say you measure a wavelength in nanometers which is common for wavelengths but then have to use this quantity in an equation with the speed of light; 300,000,000 m/s ..
You then must convert one of these quantities to get both in the same units of measure. Usually you would write 600 nm as 6x10^11 m instead of a 12 digit decimal and speed of light as 3x10^8 m/s
