if j is the number of integers between 1 and 500 that are divisible by 9 and k is the number of integers between 1 and 500 that

Morgarella [4.7K]

Answer:

126

Step-by-step explanation:

The number of numbers divisible by 9 is ...

j = floor(500/9) = 55

The number of numbers divisible by 7 is ...

k = floor(500/7) = 71

Then the total (j+k) is ...

j +k = 55 +71 = 126

Solve the following equation algebraically show the steps: <br><br><br> n/3 -5 = 5

Lana71 [14]

$\longrightarrow{\green{ \: n = 30 }}$

$\large\mathfrak{{\pmb{\underline{\red{Step-by-step\:explanation}}{\red{:}}}}}$

$\frac{n}{3} - 5 = 5$

➼ $\: \frac{n}{3} = 5 + 5$

➼ $\: \frac{n}{3} = 10$

➼ $\: n = 10 \times 3$

➼ $\: n = 30$

Therefore, the value of n is 30.

$\large\mathfrak{{\pmb{\underline{\blue{To\:verify}}{\blue{:}}}}}$

$\frac{30}{3} - 5 = 5$

✒ $\: 10 - 5 = 5$

✒ $\: 5 = 5$

✒ $\: L.H.S.=R. H. S$

Hence verified.

miv72 [106K]

Answer: 27.5 pages per hour

Step-by-step explanation:

Well, first you make the 12 minutes into an hour (times by 5), then times the pages she read (5.5) by 5, which is 27.5, so she reads 27.5 pages per hour, you can also use 27 and a half pages per hour.

Write an equation of the line that passes through (2,-4) and (0,4)

LenKa [72]

Answer:

step 1. y - y1 = m(x - x1). this is the equation given a point and a slope.

step 2. find the slope m. m = (y2 - y1)/(x2 - x1) = (4 - (-4))/(0 - 2) = 8/-2 = -4.

step 3. y - (-4) = -4(x - 2) ; y + 4 = -4x + 8.

step 4. y = -4x + 4.
