First, you replace x with -3.
It will look like -3/3.
Then you divide and get -1.
1 + 1.5x - 3 is one possibility. That's what you get when you remove the brackets.
Answer: 6cm
Step-by-step explanation:
Area of a triangle is 1/2bh
B= base
H= height
Area = 30cm
Substitute the values into the formula
Area= 1/2bh
30=1/2×10×h
30=5h
H=30/5
H= 6cm
Height of the triangle is 6cm
Answer:
2/7
Step-by-step explanation:
This is basically asking how many 7/10 's fit in 1/5. Or 1/5 divided by 7/10.
1/5 divided by 7/10 is the same as 1/5 times the reciprocal, 10/7. Therefore it is 1/5*10/7, or 10/35.
That simplifies to 2/7.
