Answer:
85
Step-by-step explanation:
when you have a number and a variable together (10x) it means multiplication.
so if you replace the x with 8, it turns into 10 × 8 which equals 80. Then, you add 5 to it and get 85.

Answer:
A = $1,650.24
Step-by-step explanation:
A = P(1 + r/n)^nt
Where
A = future value
P = present value = $1,600
r = interest rate = 3.1% = 0.031
n = number of periods = 4
t = time = 1 year
A = P(1 + r/n)^nt
= 1,600( 1 + 0.031 / 4)^4*1
= 1600( 1 + 0.00775)^4
= 1600(1.00775)^4
= 1600(1.0314)
= 1,650.24
A = $1,650.24
Answer:
P = 4w + 8
Step-by-step explanation:
<em>Jose is creating a map in the shape of a rectangle whose length is 4 inches longer than its width. Let w stand for the width of the map in inches. Write an equation gives the perimeter of the map in terms of w?</em>
Perimeter of the rectangle = 2(L +w)
L is the length of the rectangle
w is the width
If the length is 4 inches longer than its width, then;
l = w + 4
Substitute into the expression;
P = 2 (L+w)
P = 2(w+4+w)
P = 2 (2w+4)
P = 4w + 8
Hence the perimeter of the map in terms of w is P = 4w + 8
