The answer is 3 because it goes into 39 and 42 and 6 doesn't go into 39
Answer:
See below in bold.
Step-by-step explanation:
You work in fractions of the city streets done per hour:
1/200 + 1/400 = 1 /x where x is the number of hours taken by 2 teams.
Multiply through by the LCM 400x:
2x + x = 400
3x = 400
x = 133.33 hours.
As there are 168 hours in a week they will have enough time.
Answer:
it would be y= 3/4x + 2
Step-by-step explanation:
the form is y=mx+b
and you have to set it up as 8y=16-6x
Divide each term
Cancel the common factor of 8.
Divide y by 1
then simplify and turn it into a fraction.
Answer:
y=1.8
Step-by-step explanation:
first change the fraction into a decimal.
4/5 =0.8
plus the 0.8 to both sides
y=1.8
Answer:
20*6 - 120
20*6 = 120
19 * 6 = 114
Step-by-step explanation:
Call x the scale factor.
20x + 19x + 20x = 354 Add the left side together.
59x = 354 Divide by 59
59x/59 = 354/59 Combine and cancel
x = 6
The lengths of the sides are
20 * 6 = 120
19 * 6 = 114
20 * 6 = <u>120</u>
Total 354 Check
