A. is the correct answer.
There are 8 tens in the number 1,384.
Each digit in the number has an equivalent value based on its placement in the number.
1,384 where:
1 is in the thousands value
3 is in the hundreds value
8 is in the tens value
4 is in the ones value
The extended form of 1,384 is:
1 x 1000 + 3 x 100 + 8 x 10 + 4 x 1 = 1,384
1,000 + 300 + 80 + 4 = 1,384
8 x 10 = 80 ; shows that there are 8 10s in the number with a product of 80.
Answer:
a. x=8
b.Step 1: Simplify both sides of the equation.
2(2x−2)=4x−4
(2)(2x)+(2)(−2)=4x+−4(Distribute)
4x+−4=4x+−4
4x−4=4x−4
Step 2: Subtract 4x from both sides.
4x−4−4x=4x−4−4x
−4=−4
Step 3: Add 4 to both sides.
−4+4=−4+4
0=0
Answer:
All real numbers are solutions.
c. Step 1: Simplify both sides of the equation.
3(x+1)=4x+7−x
(3)(x)+(3)(1)=4x+7+−x(Distribute)
3x+3=4x+7+−x
3x+3=(4x+−x)+(7)(Combine Like Terms)
3x+3=3x+7
3x+3=3x+7
Step 2: Subtract 3x from both sides.
3x+3−3x=3x+7−3x
3=7
Step 3: Subtract 3 from both sides.
3−3=7−3
0=4

Answer:
steps below
Step-by-step explanation:
y = (x-3) / x
replace x and y: x = (y-3) / y
y - 3 = xy
y - xy = 3
y(1 - x) = 3
y (f'(x)) = 3 / (1-x)
Answer:
11/40
Step-by-step explanation:
2/5 − 3/4 (1/6)
2/5 − 1/8
= 11/40
