Answer:

x = 45 points

Round 3 : 45 points

Step-by-step explanation:

Starting Information:

100 points = 3 rounds

Round 1 : 30 points

Round 2 : 25 points

Round 3 : x

Subtraction:

To find x we need to subtract 30 and 25 from 100

100 - 25 - 30 = x points

Combine -30 and -25 into -55

100 - 55 = x

100 - 55 = 45

In round 3 he scored 45 points

Addition:

To find x we need to add 30 + 25 + x and get a sum of 100

25 + 30 + x = 100

Combine 25 and 30

55 + x = 100

Subtract 55 from each side

x = 45

Here are the 2 expressions I used:

25 + 30 + x = 100

100 - 25 - 30 = x

Note:

My work is not number assigned but hopefully you can understand it :)

Answer:

45 points in round 3

Step-by-step explanation:

x + 30 + 25 = 100

x + 55 = 100

- 55 - 55

--------------------

x = 45

therefore, Amos scored 45 points in round 3

hope this helps! :D

I need some help with solving this problem 8d-5<6d+8

Lina20 [59]

Answer: d < 13/2

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

8*d-5-(6*d+8)<0

Step by step solution :

Step 1 :

1.1 Divide both sides by 2

d-(13/2) < 0

Solve Basic Inequality :

1.2 Add 13/2 to both sides

d < 13/2

Inequality Plot :

1.3 Inequality plot for

2.000 d - 13.000 < 0

the height of a house having three rooms of the dimensional 9 feet into 12 feet 14 feet into 16 feet and 12 feet into 14 feet re

Semmy [17]

Answer:

Amount required = 2,217,600

Step-by-step explanation:

Dimensions of the rooms are as follows;

Room 1; 9 feet × 12 feet

Room 2; 14 ft × 16 ft

Room 3; 12 ft × 14 ft

Perimeter of rooms;

P1 = 2(9 + 12) = 42 ft

P2 = 2(14 + 16) = 60 ft

P3 = 2(12 + 14) = 52 ft

Total perimeter; P = 42 + 60 + 52 = 154 ft

Height is 90 ft.

Thus, total area is;

A = 154 × 90

A = 13860 ft²

Rate of painting is 160 per Sq.ft.

Thus amount to paint entire area = 160 × 13860 = 2217600

A farmer planned to plant 120 seeds in all. After planting 10 more seeds each day than was planned, she was able to finish 2 day

zheka24 [161]

Let s=number of seeds and t=number of days...

st=120 and (s+10)(t-2)=120

From the first we can say t=120/s, now using this value of t in the second equation gives us:

(s+10)(120/s-2)=120

(s+10)(120-2s)/s=120

(s+10)(120-2s)=120s

120s-2s^2+1200-20s=120s

2s^2+20s-1200=0

s^2+10s-600=0

(s+30)(s-20)=0, since s>0

s=20, and since she planted s+10 seeds per day to finish two days earlier:

20+10=30

She planted 30 seeds per day.
