The following are the true statements:
2. 7(2w) can be rewritten as 14w.
3. 7(2w - 4) can be rewritten as 7(2w) - 7(4).
7. An equivalent expression is 14w - 28.

7(2w - 4) can be expanded or simplified by first, drawing a line each from 7 to 2w and from 7 to -4. This will be a reference to you for which you should multiply by. So, 7 has to be multiplied by 2w, and 7 has to be multiplied by -4. Add these 2 multiplications up to give you (7 × 2w) + [7 × (-4)], which is also equal to 7(2w) - 7(4), hence the 3rd statement is right.

The 2nd statement is right because 7(2w) can be rewritten as 7 × 2 × w, which is also 14 × w, or 14w.

The 7th statement is right, since,
7(2w) - 7(4)
= 14w - 7(4)
= 14w - 28

Hope this helps! :)

Jackson purchased some power tools totaling $1,543 using a six month deferred payment plan with an interest rate of 23.76%. He d
skad [1K]
Suppose he makes the payment with two equal annual instalments, the present value of the amount he is owing is $1,543 , the interest rate is 23.76% = 0.2376.

The amount of payment he makes in two of the periodic payments is given by:

PV = P\left( \frac{1-(1+r)^{-n}}{r} \right) \\  \\ \Rightarrow1,543=P\left( \frac{1-(1+0.2376)^{-2}}{0.2376} \right) \\  \\ =P\left( \frac{1-(1.2376)^{-2}}{0.2376} \right)=P\left( \frac{1-0.6529}{0.2376} \right) \\  \\ =P\left( \frac{0.3471}{0.2376} \right)=1.4609P \\  \\ \Rightarrow P= \frac{1,543}{1.4609} =1,056.20

Therefore, in 2 years, the amount he has paid for the tools is 2(1,056.20) = 2,112.40

(03.01 LC) Given that h(x) = 3x −19, find the value of x that makes h(x) = 71. (5 points)
LekaFEV [45]
The function given is:
h(x) = 3x-19
we want to find the value of x that makes this function equal to 71. To do so, we will substitute h(x) with 71 and solve for x as follows:
h(x) = 3x - 19
71 = 3x - 19
3x = 71+19
3x = 90
x = 90/3 = 30

Kendrick opened a savings account and deposited $3,000.00 as principal. The account earns 6% interest, compounded quarterly. How
IRISSAK [1]

Answer:

Amount of interest after 7 years = $12335.06

Step-by-step explanation:

First total number of quarters in 7yrs is calculated

a year has four quarters, hence 7yrs will have = 4 x 7 = 28 quarters

Using the compound interest expression

Amount after 7 yrs = P(1+r%)²⁸

A = 3000 (1+0.06)²⁸ = $15335.06

Hence amount of interest after 7 years = 15335.06 - 3000 = 12335.06
