Answer:
20 builders
Step-by-step explanation:
Answer:
1) 194
2) 480
3) 144
4) 2m > 84 $
4m > 168 $
10m> 420 $
13m> 546$
Step-by-step explanation:
1) 582 in 30 mins ... so in third the time 582÷3 = 194
2)120 tools in 5 hours , so 120 ÷ 5 = 24 tools per hour > so 24 × 20 = 480
3) 1kg is for 18$ ... so 8kg will be 8 × 18 = 144
4) 5meters cost 210$ , one meter costs 210÷5 =42
now multiply , 2×42 = 84 , 4×42 = 168 , 10×42= 420 , 13×42 = 546
sorry the last question isn't showing for me , i can't see it
2x + 12 = 18
18 - 12 = 6
2x = 6
x = 3
Answer:
y = x + 8
Step-by-step explanation:
For 8cm of thread, 1cm of the bracelet may be produced. therefore being y(thread) = x(bracelet) with the addition of 8 (+8). Hope this helps!
Answer:
12 miles
Step-by-step explanation:
Let the amount of hours it takes Leroy to catch up to Kevin equal x. Since speed multiplied by time is distance, Leroy would have run a total of 6x miles(6*x). Kevin already had a head start of 24 minutes, which is the same as 2/5 of an hour. In 2/5 an hour, Kevin ran 2 miles as 2 is 2/5 *5. For the next x hours his distance would be a total of 5x(5*x). This means, after x hours, Kevins distance is 5x + 2. In this case, catching up to someone is the same as having the same distance value. This means we can set the two expressions equal to each other, and solve:
6x = 5x + 2
x = 2
The time it took Leroy to catch up is 2 hours, but we are looking for the distance, which is represented by 6x. We substitute in 2 to get:
6(2) = 12
This means Leroy had to run 12 miles.
