X-2=27
is this a good equations
The three numbers have to multiply to 48 in a ratio of 3:2:1
which would be 6:4:2
so 6 inches
Answer: 3.5 h
Step-by-step explanation:
<u>1. Data:</u>
a) s = 740 miles / h
b) d = 2,567 miles
c) t = ?
<u>2. Equation:</u>
<u>3. Solution:</u>
- Solve the equation for t:
s = d / t ⇒ t = d / s
t = 2,567 miles / (740 miles/h) ≈ 3.47 h ≈ 3.5 h
Answer:
A) 1:2
B) 3:5
C) 5:4
D) 17:5
Step-by-step explanation:
Step 1) Convert the decimal number to a fraction
Step 2) Multiply the numerator and denominator by 10 to eliminate the decimal point.
Step 3) Simplify the fraction in the previous step by dividing the numerator and the denominator by the greatest common factor (GCF)
Step 4) Convert the fraction in the previous step to a ratio by replacing the divider line with a colon
Heres an example. I'll do the last one.
3.4 = 3.4/1
(3.4 x10) /(1 x 10)= 34/10
34 /2 = 17
10/2 = 5
17/5 = 17:5
