Answer:
22.5 kilometers
Step-by-step explanation:
we know that
The scale drawing is
That means
1 unit on a map represent 250,000 units in the actual
or
1 cm on a map represent 250,000 cm in the actual
or
1 cm on a map represent 2,500 m in the actual
or
1 cm on a map represent 2,5 km in the actual
therefore
using proportion
Find out how much represent 9 cm apart on the map
Use calcutlator and it all smushed up i can barley see it
Answer:
-9/10
Step-by-step explanation:
when dividing fractions, the second fraction flips upside down. Then you just multiply.
-4/5 divided by 8/9 becomes -4/5 * 9/8 = -36/40 = -9/10
Answer:
y-5=3x-15
Step-by-step explanation:
Slope=(5+1)/(-6+8)
=6/2
=3
Equation of line passing throgh point (-6,5):
y-5=3(x-5)
y-5=3x-15
Answer:
#1: x = 3; #2 c = 1/2; #3 = x = 22; #4 is correct (x = -8)
Step-by-step explanation:
for the first equation everything was right until 22x = 66
after
22x = 66
you must divide everything by 22
x = 3
that is for #1
for the second equation you copied down the question wrong
the negative is still there
6c - 8 - 2c = -6
combine 6c and -2c
4c - 8 = -6
the negative remains on the 8
add 8 to both sides
4c = 2
divide 4 to both sides
c = 2/4 or just 1/2
for the third equation you must first combine like terms
-3x + 25 + x + 21 = 2
combine -3x and x & 25 and 21
-3x + x = -2x
25 + 21 = 46
-2x + 46 = 2
then subtract 46 from both sides
-2x = -44
now divide both sides by -2
x = 22
that is your answer
number four should be correct
