Answer:
adults : 0 children: 600
Step-by-step explanation:
x + y = 600
6x+4y = 2400
4×(x + y = 600) = 4x+4y = 2400
(6x+4y = 2400) - (4x+4y = 2400) = x=0
so y=600
The point (4,y) has a known x coordinate of x = 4. The y coordinate is unknown right now so we'll just call it y.
Draw a vertical line (see side note below) through 4 on the x axis. I've done so in red (see attached image). The red line crosses the graph at the point (4,1) so this tells us that
y = 1Answer: y = 1
Side Note: you don't have to draw a vertical red line but it's handy to see how it works out. After you get used to these types of problems, you can visually be able to see the answer without these extra lines.
Answer:
Choice D.) 434,500
Step-by-step explanation:
What is 4.345 x 10^5 in standard form?
4.345 x 10^5 = 4.345 * 100,000
multiply it out:
4.345 x 10^5 = 434,500
Answer:
(-x)(x^2 + 4x + 5)
Step-by-step explanation:
You have to factor out the -x from the rest of the expression.
Volume of rectangular prism= 30 cm³
Formula for volume of rectangular prism:
V=whl
Scale factor of second prism= 3.5
Which is 3 and a half times greater than the 1st one.
So volume of 2nd prism = 3. 5 x 300
V= 1050 cm³
Answer: Volume of second Rectangular Prism is 1050 cm³
