Parentheses first lets do 10 + 4 * 8; Using order of operations, you know we do multiplication before addition so 4*8 = 32, now you can do 32+10 to get 42. Now the equation is 3{5 + 3(42)}, Now remember you do multiplication before addition so you distribute the 3 to the 42 to get 126. The new equation is 3(5+126) Now remember do the parentheses first, 126 + 5 = 131. Now distribute the 3; 3(131) = 393

Answer: 393 :)

1. Jared borrowed $300 from his mother to buy an x-box 360. Jared will pay her back in 4 years with 3.5% simple interest. How mu
BigorU [14]

Answer:

1) future value = present value x [1 + (i x n)] = $300 x [1 + (3.5% x 4)] = $342

2) using the compound interest formula:

future value = $225 x (1 + 4.1%)¹°⁵ = $238.98

Using the simple interest formula doesn't yield the same answer = $225 x [1 + (4.1% x 1.5)] = $238.84. In this case it is close due to a very short period of time and low interest rate.

3) future value = present value x (1 + i)ⁿ = $1,700 x (1 + 6%)⁴ = $2,146.21

since the interest is annual, we must convert 48 months to 4 years

What does X=?<br> I cannot figure out how to solve this problem please help!
Alona [7]

Answer:

Step-by-step explanation:

S = (n - 2).180°

n = quantity of sides

S = all angles addition

S = (5 - 2).180°

S = 3.180°

S = 540°

104 + 117 + 100 + 124 + x = 540

445 + x = 540

x = 540 - 445

x = 95°

I hope I've helped you.

Two less than the product of<br> 5 and the cube of a number.
slavikrds [6]

Answer:

5x^3-2

Step-by-step explanation:

Two less than the product of 5 and the cube of a number.

The product of 5 and the cube of a number can be translated to look like 5x^3.

You then take 5x^3 and subtract 2 to get 5x^3-2.
