3x + 12 - 6x < -9
-3x +12 < -9
-3x < -21
x < 7
Answer:
If it 23x - 4=65 then it x=3, but if it 23x(-4)=65 then it x=−0.707
Answer:
If you need the equation: 10x - 12
If you need the equation more simplified: x - 1.2
Step-by-step explanation:
(2x + 7) - (8x + 5)
Move the parts of the equation around
(2x + 8x) - (7 + 5)
Add 2x and 8x together
10x - (7 + 5)
Add 7 and 5 together
10x - 12
If you need it even more simplified, continue
10x - 12
Divide by 10
x - 12/10
Simplify
x - 1.2
I Hope That This Helps! :)
256.
EXPLANATION:
When you are using exponents, you are basically just doing repeated multiplication.
Whatever the exponent (smaller number is) is how many times you multiply the base number by itself.
So 4 ^4 is 4 x 4 x 4 x 4. (4 fours.)
So 4 x 4 x 4 x 4 is 256.
HAVE A GUD DAY
1 hm=100m
1.5hm=150 meters each tower is from each other.
500km(1000m/1km)=500,000 meters the wire covers.
500,000/150 = 3333.33 towers. Just because we want to be safe and have enough towers we can say we have 3334 towers in the span of 500,000 meters.
B)
1kV=1000V
500kV(1000V/1kV)= 500,000 V
There are 1.2 volts in a AA battery so we divide 500,000/1.2 = 416666.67 times larger
