Answer:
A
Step-by-step explanation:
By doing the unit rate, dividing 19 on both the top and bottom, getting this 8.36.../1, you can just round it to 8/1, meaning he makes about 8 deliveries per hour. Hope this helps!
It takes 5 shovels of sand to make 1 shovel of mortar so how many will it take to have 30 shovels of mortar? You can put this in a proportion.
5/1 = x/30
You don't need to worry about the cement since it's asking for sand.
Cross multiply and you get x·1 and 30·5. So this means you need 150 shovels of sand. x=150 when you multiply 30·5.
Answer:
x = 3

Answer:
Hey there! First you start with parenthesis! So distribute the 2 to 3x. There you get 6x. Now distribute to the 3. You get 6. Now you move the 2x over to the right side. Getting 30=4x+6.. Now move the 6 over to the 30. You get 24=4x..Now you divide, getting the answer 6! Hope this helps...
