Answer:
d = 1.7
Step-by-step explanation:
Given expression:
2.50 +7.75 = 4 + 3.75d
Problem:
Solve for d;
Solution:
Collect all like terms to the same side;
2.50 + 7.75 - 4 = 3.75d
6.25 = 3.75d
Divide through by 3.75 to find d;
d = 1.7
4x - 4y = 10
1. Factor out the common term 4
4(x - y) = 10
2. Divide both sides by 4
x - y = 10/4
3. Simplify 10/4 to 5/2
x - y = 5/2
4. Add y to both sides
x = 5/2 + y
3x + 2y = 5
1. Subtract 2y from both sides
3x = 5 - 2y
2. Divide both sides by 3
x = 5 - 2y/3
Answer:
18√2
Step-by-step explanation:
2√3 x 3√6
2 x 3 x (√6 x √3)
=> 6√18
=> 6√(3x3x2)
=> 6 x 3√2
=> 18√2
Answer:
A question on a test provides this graph
You, however, did not provide the graph.
Please repost the question along with the graph.
To determine the amount of gold plating necessary for the similar box, you will use the fact that it is 8 times larger in volume to determine how many times larger the area is. This would be what you will multiply $125 by.
Volume is a three dimensional measurement, so the fact that it is 8 times larger tells us each dimension was 2 times larger (2 x 2 x 2=8).
Area is a two dimensional measurement, so the area would have been 2 x 2 or 4 times larger. This means the price would be 4 times as much.
$125 x 4 = $500.
It will cost $500 to gold plate the similar jewelry box.
