5x-3=42. To solve you add three to both sides making the equation 5x=45. Then you divide both sides by five, and you get 9 as your answer.
Answer: 50
Step-by-step explanation:
3(50)-14=136
This is the concept of areas of solid figures. The surface are of the solid figure formed when 2 square pyramids are attached will be given by:
SA=[number of triangular faces]*[Area of each triangle]
Number of triangular faces=8
Area of each triangle=1/2*bh
base=6/4=1.5 cm
height=2 cm
thus;
Area=1/2*2*1.5=1.5
The surface area will therefore be:
SA=1.5*8=12cm^2
Quotient means divide, meaning we'll divide 6 by -1/2.

When dealing with fraction division, we flip the fraction in the second place and then change the problem to multiplication.

Anything over 1 is just itself, so -2/1 becomes -2.

Finally, we multiply 6 and -2.

So the quotient of 6 and -1/2 is -12.
