Answer:
144 boys and 384 girls
Step-by-step explanation:
8 girls to every 3 boys. You can make an equation to solve this: 8x + 3x = 528. 528 = 11x. Then divide 528 by 11 to get 48. x=48. 8(48) = 384 girls. 3(48) = 144 boys.
The answer is b why because I had did it on the test and I had got it right HOPEFULLY IT HELPS
Answer:
G. 10.5 pounds
Step-by-step explanation:
96 oz + 72 oz = 168 oz
There are 16 oz in one pound
168 oz / 16 oz = 10.5 pounds.

Hi there! See an attachment below! (May not be clear for an explanation so I will explain it to you.)
We can find real roots of polynomial function by counting their x-intercepts of graph. See in the attachment that the graph intersects 3 points on x-axis/plane.
x-axis represents the solutions of the graph or equation of the graph. For example, a graph of (x-1)² would be a parabola that has x-intercept at (1,0). If we solve the equation for (x-1)² = 0, our solution would be x = 1 like the x-intercepts.
Conclusions
- We can find the real roots of the graph by counting how many points does the graph intersect on x-axis/plane.
- If a graph doesn't intersect x-axis or does not have any points on x-axis, that graph or its equation does not have a real root. For example, graph of x²+1

Answer: (-6, 4)
Step-by-step explanation:
You can use the Elimination method:
- Multiply the the first equation by -3 and the second one by 5.
- Add both equations.
- Solve for y:

- Susbtittute y=4 into any of the original equations and solve for x:

Then the ordered pair is:
(-6, 4)
