Answer:
Step-by-step explanation:
50 + 30 = 80
The answer is 56! I used a double number line! You have to get the unit rate first! Unit means 1, you have to get from 12 to 1! I did 12 divided by 12, and got 1! Whatever I do to the bottom I do to the top. So I divided 60 by 12 and got 5. Now we have to get to seven, so I multiplied 1 x 7 and got 7. Than I multiplied 5 times 7 and got 56! I hope <em>I helped! :D</em>
Answer:
129° and 37°
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
(a)
∠ 1 is an exterior angle, thus
∠ 1 = 62° + 67° = 129°
(b)
∠ 1 + 115° = 152° ( subtract 115° from both sides )
∠ 1 = 37°
Answer: 5 1/4
Step-by-step explanation:
Answer:
14 stacks
Step-by-step explanation:
Given :
There are 70 red colored blocks
There are 84 green colored blocks
The ratio of green blocks to red blocks is 
Therefore, the ratio of g : b = 1.2 : 1
or g : b = 6 : 5
Therefore, in order to calculate the number of stacks , we divide 84 by 6 and we get 14.
So we will get 14 block stacks to be made of 6 green blocks and 5 red blocks.
