1. In this problem, the variable x represents how many pounds of hamburger meat you're buying. So, to solve the expression, just replace x with how much you're buying, in this case, 7.
2.50x Plug in 7 pounds for x
2.50(7) Multiply
17.50
You will pay $17.50 for 7 pounds of hamburger meat.
2. 8 times (8 x) the product (multiplication) of g and h.
The product of g and h means you multiply them, so it will be gh. Then, you'll multiply that by 8 and get 8gh. So, the correct answer is choice B.
Answer:
Step-by-step explanation:
72
B. 237,600 people. You would find the Square feet of one side of the street. Which is length times width. 15,840ft (3 miles)x 30 ft. Double the the amount to count for the other side of the street, then divide by 40 and multiply by 10.
<h3>Answer: 133 cm</h3>
============================================================
Explanation:
I'm going to relabel the figure as triangle ABC.
As the instructions mention, we'll use the law of cosines to find the missing side.
- side a = 147
- side b = 166
- angle C = 50 degrees
Use these facts to find side c
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 147^2 + 166^2 - 2*147*166*cos(50)
c^2 = 17794.393497
c = sqrt(17794.393497)
c = 133.395628
c = 133
