Answer:
15/4
Step-by-step explanation:
multiply the whole number (3) by the denominator (4), then add the numerator (3) then put that over the denominator to convert any mixed number into an improper fraction.
Answer: 3/5
Step-by-step explanation:
1. Multiply 30 by 3 (90)
2. 90 becomes the numerator and 150 becomes the denominator
3. Divide the numerator (90) and the denominator (150) by the greatest common factor (30), to simplify the fraction
4. You should come to the answer 3/5
Hope this helps.
4t+2c=200
2t+7c=400
I will solve for c in terms of t first
4t+2c=200
2c=200-4t
c=100-2t
Then I will substitute this in for c in the second equation to make it single variable
2t+7c=400
2t+7(100-2t)=400
2t+700-14t=400
300t=12
t=25
Tables cost $25 each
Plug t back into one of the ORIGINAL equations to find the cost of chairs
4(25)+2c=200
100+2c=200
2c=100
c=50
Chairs cost $50 each
Hope this helps! :)
Answer:
75
Step-by-step explanation:
o find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.
Answer:
2/2 3/3 4/4 5/5
Explanation: Have the fraction sign act like a division sign. 2 divided by 2 is 1. 3 divided by 3 is 1, and so on
