Answer:
13 weeks
Step-by-step explanation:
In the picture attached, data of the problem is shown in a table.
Althea wants to save $384, in plan B she saves $30 each week. The amount of weeks needed is obtained dividing the total amount to save by the amount saved per week, that is:
equation: $384÷$30 = 12.8 weeks
Here, weeks are considered integers, so you have to round this value to the next integer, that is, 13 weeks. To better understand this, suppose you take 12 weeks saving $30 per week, after 12 weeks you will save: $30*12 = $360, which is not enough; with 13 weeks you will save: $30*13 = $390.

Answer:
· This image may result from the construction of <em>an angle congruent to a given angle</em>.
· The next step in this construction is to set the compass width to <em>arc JK and draw an arc centered at L intersecting the existing arc through L</em>.
Step-by-step explanation:
If the step shown above results in point of intersection P, and the construction is completed by drawing ray DP, then this construction produces triangle DLP congruent to triangle BKJ. The angle at D will be congruent to the angle at B because CPCTC. Hence an angle congruent to a given angle will have been constructed.
4.8 x 10^-2
You can do this without a calculator
Explanation:
(3.2 x 10^-5) x (1.5 x 10^3)
First, you multiply 3.2 by 1.5 to get 4.8
Next, you add the exponents together: -5 + 3 = -2
Now, put everything into one answer (the 10 stays the same): 4.8 x 10^-2
X/3 = x + 2/5....multiply everything by common denominator of 15
5x = 15x + 6
5x - 15x = 6
-10x = 6
x = -6/10 reduces to - 3/5
or...
x/3 is the same as 1/3x
1/3x = x + 2/5
1/3x - x = 2/5
1/3x - 3/3x = 2/5
-2/3x = 2/5
x = 2/5 * -3/2
x = - 6/10 which reduces to - 3/5
