Answer:
The required equation is 5x - 3 = 12
Step-by-step explanation:
We have to find the equation for the given condition
Let the number be x as given in the equation
Now according to the condition
5 time the Number is 5 *x = 5x
Three less then 5 time the Number would be 5x - 3
And all of it is equal to 12
Which gives us the equation
5x - 3 =12
The required equation is <em>5x - 3 = 12</em>
Answer:
x = 20 cm
Step-by-step explanation:
The triangles given are similar triangles because they share the same angles. Because they are similar, their side lengths are in the same ratio, or proportion to one another. The left side of the larger triangle has a length of 121cm + 11cm = 132cm where the smaller triangle only has a length of 11 cm. We can put these lengths into a ratio:
Since the other side of the triangle would have to be in the same proportion, or ratio, we can set up the following proportion:
Use cross-multiplication: 5x + 20 = (10)(12) or 5x + 20 = 120
Subtract 20 from each side: 5x + 20 - 20 = 120 - 20 or 5x = 100
Divide and solve for 'x': 5x/5 = 100/5 or x = 20 cm
Answer:
D - No, the ordered pair (4,9) is a solution to this problem.
Step-by-step explanation:
If you plotted the number of snacks as the x-axis, and then the total cost of the snacks on the y-axis, you would be able to graph a line and see the cost of snacks based on the number purchased. If you were going to write an equation for this, it would be y=2.25x (or y = 2 1/4 x)
In this case, as each snack is the same price, the y-values for each x would be as such: (1, 2.25) <- one snack, $2.25;
(2, 4.5)
(3, 6.75)
(4, 9)
So that is why the ordered pair of (4,9) would be a solution to this problem.
Hope that makes sense!
WX/RS = (28 ft)/(40 ft) = 7/10
Selection D is appropriate.
