Answer:

Solve the following equations, and explain its each step.

6. 6x +3= 5x + 10

Solution given:

6x +3= 5x + 10

Subtracting both side by 5x

6x-5x+3=5x-5x+10

x+3=10

subtracting both side by 3

x+3-3=10-3

x=7

7. 6+ 0.10x = 0.15x+8

Subtracting both side by 0.15x

6+0.10x-0.10x=0.15x-0.10x+8

6=0.05x+8

subtracting both side by 8

6-8=0.05x+8-8

-2=0.05x

dividing both side by 0.05

-2/0.05=x

x=-40

8. 5-4x=6+2x

adding 4 on both side

5-4x-4x=6+2x+4x

5=6+6x

subtracting both side by 6

5-6=6-6+6x

-1=6x

dividing both side by 6

-1/6=6x/6

x=-1/6

9. 9-2x=7x

Solution given

adding 2x on both side

9-2x+2x=7x+2x

9=9x

dividing both side by 9

9/9=9x/9

x=1

10. 2(x-4) + 2x = -6x-2

open bracket

2x-8+2x=-6x-2

solve like terms

4x-8=-6x-2

adding 6 on both side

4x+6x-8=-6x+6x-2

10x-8=-2

adding 8 on both side

10x-8+8=-2+8

10x=6

dividing both side by 10

10x/10=6/10

x=3/5

11. ½x-3=3/2 x+4

Subtracting both side by ½x

½x-½x-3=³/2 x-½ x +4

solve like terms

-3=x+4

Subtracting both side by 4

-3-4=x+4-4

x=-7

A right triangle has legs measuring 4.5 meters and 1.5 meters. The length of tge legs of a second triangle are proportional to t
Leviafan [203]
If the legs of both triangles are supposed to be proportional then they would be equal in length because that's what proportional means

so if the legs of one triangle are 4.5 and 1.5 then the other triangle "if proportional" would have legs with the same measurements which are 4.5 and 1.5

A cyclist averages 18.5 miles per hour. how many minutes will it take for him to complete a 125 kilometer race?
rjkz [21]
step 1
convert miles to km
1 mile is-----> 1.60934 km
18.5 miles/hour-----> 18.5*1.60934=29.77 km/hour

step 2
convert km/hour to km/minutes
29.77 km/hour--------> 29.77/60----> 0.4962 km/minutes

step 3
by proportion
0.4962 km/1 minutes=125 km/x minutes
0.4962 km----------> 1 minute
125 km-------------> x

x=125/0.4962----> x=251.91 minutes---------> x=251.9 minutes

the answer is
251.9 minutes

Alternative Method

step 1
convert km to miles
1 km is-----> 0.621371 miles
125 km-----> 125*0.621371--->77.67 miles

step 2
convert miles/hour to miles/minutes
18.5 km/hour--------> 18.5/60----> 0.3083 miles/minutes

step 3
by proportion
0.3083 miles/1 minutes=77.67 miles/x minutes
0.3083 miles----------> 1 minute
77.67 miles-------------> x

x=77.67/0.3083----> x=251.9 minutes
