Solve for b. (b-7)m=r

Mathematics
1 answer:
deff fn [24]2 years ago
3 0

(b-7)m=r

Use the distributive property to multiply b-7 by m.

bm-7m=r

Add 7m to both sides.

bm=r+7m

The equation is in standard form.

mb=7m+r

Divide both sides by m.

mb/m = 7m+r/m

Dividing by m undoes the multiplication by m.

b= 7m+r/m

Divide r+7m by m.

b= r/m+7

Suppose you obtain a $1,300 T-note with a 9% annual rate, paid monthly, with maturity in 6 years. How much interest will be paid
Tems11 [23]
We know that,
Interest, I = \frac{P×R×T}{100}
Where, P = Principal = $1300
R = rate of interest = 9% annually = \frac{9}{12}%
T = Time  = 1 month

So, I = \frac{1300×[tex] \frac{9}{12}×1}{100} [/tex]
        = $9.75

Interest paid per month is $9.75

Beth is making a rope ladder each step of the ladder is 2 1/3 feet wide width as a rope that is 21 feet long how many steps can
Helga [31]

Answer:

Answer: She can make 9 steps from the rope.

Step-by-step explanation:

Given : The width of each step of the ladder = 2\dfrac{1}{3}\text{ feet}2

3

1

feet = \dfrac{2(3)+1}{3}=\dfrac{7}{3}\text{ feet}

3

2(3)+1

=

3

7

feet

The length of the rope = 21 feet

Then , the number of required steps = ( length of the rope ) ÷ (width of each step of the ladder)

=21\div\dfrac{7}{3}=21÷

3

7

=21\times\dfrac{3}{7}=3\times3=9=21×

7

3

=3×3=9

Hence, the number of steps can she make from the rope = 9.
