How do i solve divide 5/8 by 50%
Answers
We have two ways to do this, pick your favor:
either by fractions:
(
Multiply by the reciprocal of
Or change them to decimals:
0.625 ÷ 0.5
0.5 I 0.625
multiply by 10 to make it easier to divide(it still gives us the same answer)
0.5 × 10 = 5
0.625 × 10 = 6.25
1.25
5 I 6.25
-5
12
-10
25
-25
0
0.625 ÷ 0.5 = 1.25

Answer:
here's an example related
Step-by-step explanation:
Let's call f(x) = 2x - 4 and g(x) = 3⁻ˣ + 1.
First, you need to evaluate each function at the given values of x.
f(1) = 2(1) - 4 = -2
f(3.25) = 2(3.25) - 4 = 2.50
f(2.5) = 2(2.5) - 4 = 1
f(2) = 2(2) - 4 = 0
Similarly:
g(1) = 3⁻¹ + 1 = 1.33
g(3.25) = 3⁻³'²⁵ + 1 = 1.03
g(2.5) = 3⁻²'⁵ + 1 = 1.06
g(2) = 3⁻² + 1 = 1.11
Now, look for the value of x for which f(x) ≈ g(x): this happens for x = 2.5
Therefore the correct answer is c) x ≈ 2.5

"What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8?"
It is a geometric sequence =>U(2)=U(1)*r==>-8=2*r ==>r=-4
U(1)=2=2*(-4)^0
U(2)=-8=2*(-4)=2*(-4)^1
U(3)=32=-8*(-4)=2*(-4)(-4)=2*(-4)^2
U(4)=-128=32*(-4)=2*(-4)^3
...
U(n)=2*(-4)^(n-1) where n>=1.
Answer C
2 = m/2-7
Answers
m/2 - 7 = 2 Flip flop the equation around.
m/2 = 9 Add 7 to each side.
m = 18 Multiply each side by 2.
Answer: m = 18
Step 2: 5x − 7 = 14 + 2x
Step 3: 5x − 2x = 14 + 7
Step 4: 3x = 21
Step 5: x = 7
In which step did the student first make an error and what is the correct step?
Step 2; 6x − 12 = 14 + 2x
Step 2; 6x − 7 = 2(6 + x + 4)
Step 3; 5x − 2x = 14 − 7
Step 3; 5x + 2x = 14 + 7
