Answer:

1 5/24

Step-by-step explanation:

Common denominator is 24 so when you multiply 1/3 by 8 for the numerator and denominator it’s is equal to 8/24 and then you do the same for the other number except multiply by 3 which 21/24 then add together is 29/24 then simplified is 1 5/24

I have 47 nickels and dimes worth $4.20. How many of each type of coin do I have?
soldi70 [24.7K]

Answer:

37 dimes and 10 nickels

Step-by-step explanation:

let d = # dimes

let n = # nickels

we can set up a system of equations:

n + d = 47

.05n + .10d = 4.2

if we solve the first equation for 'n' we get:  

n = 47-d

now we can substitute this in for 'n' in the second equation:

.05(47-d) + .10d = 4.2

2.35 - .05d + .10d = 4.2

2.35 + .05d = 4.2

subtract 2.35 from each side to get:

.05d = 1.85

d = 1.85÷.05

d = 37

if d+n = 47 and d=37 then n = 10

Check:

.05(10) + .1(37) should equal 4.2

.50 + 3.7 = 4.2  [It Checks Out]

Write the equation of the line in fully simplified slope-intercept form.
FrozenT [24]

Step-by-step explanation:

y — yı = m(x – xı) equation of a line

Points A(1,3) and B(2,1)

Slope (m) = (y2 – y1) / (x2 – x1)

(1 –3) / (2 – 1)

–2/1

–2

Thus, y –3 = –2 (x – 1)

y – 3 = –2x + 2

y –3 + 3 = –2x + 2 + 3

y = –2x + 5

What is the equation of a line whose slope is 2 and passes through the point (-6,9)
yuradex [85]

Answer:

y = 2x + 21

Step-by-step explanation:

Step 1: Write out known variables

y = mx + b

m = 2

y = 2x + b

Step 2: Find <em>b</em>

9 = 2(-6) + b

9 = -12 + b

b = 21

Step 3: Rewrite linear equation

y = 2x + 21
