Answer:

Any values for n that are greater than 4 will satisfy the expression

Step-by-step explanation:

We have the expression

7n/4 > 7 solve for n...

7n > 28 multiply by 4 on both sides

n > 4 divide by 7 on both sides,

n is greater than 4, so any value for n greater than 4 will satisfy the inequality

In the Itty Bitty High School, there are 85 students. There are 27 students who take French, 51 who take Geometry and 38 who tak

andrew-mc [135]

Answer:

58 students

Step-by-step explanation:

Given

$Total = 85$

$French = 27$

$Geometry = 51$

$History = 38$

$None = 5$

$All = 2$

Required

Students that take only 1 subjects

The attached image illustrates the question.

For French only (x), we have:

$x + 7 -2+10-2+2=27$

$x + 15=27$

Collect like terms

$x =- 15+27$

$x =12$

For Geometry only (y), we have:

$y+10-2+15-2+2=51$

$y+23=51$

Collect like terms

$y=-23+51$

$y=28$

For History only (z), we have:

$z +15-2+7-2+2=38$

$z +20=38$

Collect like terms

$z =-20+38$

$z =18$

Students with one subject is then calculated as:

$1\ subject = x+y+z$

$1\ subject = 12 + 28 + 18$

$1\ subject = 58$

Jennifer is making bouquets of flowers. She has 25 roses, 45 tulips, and 15 snapdragons. She divides the flowers equally to make

chubhunter [2.5K]

Answer:

a. 3

Step-by-step explanation:

The number of flowers should be divisible by the number of bouquets.

Since

$25 = 5 \times 5 \\ 45 = 5 \times 9 \\ 15 = 5 \times 3$

there should be 5 bouquets, and each bouquet has 5 roses, 9 tulips and 3 snapdragons.

so the answer is

a. 3

Masja [62]

Answer: The answer would be c

Step-by-step explanation:

Step 1: Solve for b

5a+b=7

b=-5a+7

your slope would be -5a

Step 2: Make it perpendicular

The Perpendicular is gonna be the opposite

So it would be b= 1/5+7

The slopes has to be different and you don't have to worry about the "+7"

What is the solution to w-11=1.3

trapecia [35]

<span>Simplifying w + -11 = 1.3

Reorder the terms: -11 + w = 1.3

Solving -11 + w = 1.3

Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + w = 1.3 + 11

Combine like terms: -11 + 11 = 0 0 + w = 1.3 + 11 w = 1.3 + 11

Combine like terms: 1.3 + 11 = 12.3 w = 12.3

Simplifying w = 12.3 <--- (Answer)

Happy studying ^-^</span>
