X+y=29.8
Y=29.8-x so
1.45x+1.55(29.8-x)=20 then solve for x
1.45x+46.19-1.55x=20
-0.1x=20-46.19
-0.1x=−26.19
X=26.19/0.1
X=261.9
Y=29.8-261.9
Y=−232

Find the value of each variable in the parallelogram.
Nikitich [7]

Answer:

u = 4; v = 18

because this is a parallelogram

=> 2u + 2 = 5u - 10

6 = v/3

<=> 3u = 12

v = 6.3

<=> u = 4

v = 18

5 divided by 2,165 equals?
Mekhanik [1.2K]

answer:

1/433 (decimal: 0.002309)

step-by-step explanation:

5/2,165

= 1/433

to change 1/433 to decimal we'll divide the numerator by the denominator-

1÷433

=0.00230946882

so we're going to round to the ten-millionths place

5 or more raise the floor, 5 or less let it rest

4>5

so 0.002309

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!
