Together, Linda and Penny sold 492 boxes of Girl Scout cookies. Penny
sold 48 more boxes than Linda. How many boxes did Linda sell?
Answers
Answer:
222
Step-by-step explanation:
Let L = number of boxes Linda sold.
Let P = number of boxes Penny sold.
The sold a total of 492 boxes.
L + P = 492
Penny sold 48 more boxes than Linda.
P = L + 48
Substitute P with L + 48 in the first equation and solve for L.
L + L + 48 = 492
2L + 48 = 492
2L = 444
L = 222
Answer: Linda sold 222 boxes.
Check:
Penny sold 48 more boxes, so she sold 222 + 48 = 270.
Add the numbers they sold: 222 + 270 = 492
The difference is 48, and the total is 492. Our answer is correct.

Sonji's wires measure 12 inches, 8 inches, and 17 inches. Liam's wires measure 16 inches, 8 inches, and 27 inches.
Answers
Answer:
Sonji's wires measure will be chosen
Step-by-step explanation:
Given:
Don's wires measure = 3 inches, 5 inches, and 12 inches
Margo's wires measure = 6 inches, 8 inches, and 14 inches
Sonji's wires measure = 12 inches, 8 inches, and 17 inches
Liam's wires measure = 16 inches, 8 inches, and 27 inches.
Find:
Measure used to construct a triangle
Computation:
In a triangle sum of two smaller side is grater then bigger side
a + b > c
So.
Don's wires measure = 3 inches + 5 inches < 12 inches
Margo's wires measure = 6 inches + 8 inches = 14 inches
Sonji's wires measure = 12 inches + 8 inches > 17 inches
Liam's wires measure = 16 inches + 8 inches < 27 inches.
So,
Sonji's wires measure will be chosen

The density of a certain material is such that it weighs 4 kilograms
per cubic foot of volume. Express this density in ounces per cubic
meter. Round your answer to the nearest whole number.
Answers
Answer:
4986 ounces/m³
Step-by-step explanation:
1 kilogram = 35.274 ounces
1 cubic foot = 0.0283 cubic metre
We are converting kg/ft³ to ounces/m³
Hence:
4kg/ft³ × 35.274 ounces/ 1 kg × 1 ft³/0.0283m³
= 4985.7243816 ounces/m³
Approximately to the nearest whole number = 4986 ounces/m³

A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction. You can turn a figure 90°, a quarter turn, either clockwise or counterclockwise. When you spin the figure exactly halfway, you have rotated it 180°. Turning it all the way around rotates the figure 360°.
