Answer:

y = -9/2 x +5

Step-by-step explanation:

Answer:

y = - 9/2 + 5

Step-by-step explanation:

9x + 2y = 10

Move 9x to the other side. (It becomes negative)

2y = - 9x + 10

Divide both sides by 2.
y = - 9/2 + 5

Esther cut a square paper vertically to make two rectangle pieces. Each rectangle had a perimeter of 63 inches.

Studentka2010 [4]

Answer:

Side of the square paper = 21 inches

Step-by-step explanation:

Let the square paper is having measure of each side = a inches

Esther cut this square piece into two pieces.

Let the other side of one rectangle piece = x inches

Perimeter of this piece = 2(a + x) inches

Similarly dimensions of the other rectangular piece will be = a inches × (a - x) inches

Perimeter of this piece = 2[a + (a - x)]

Since both the rectangular pieces have the same perimeter = 63

So, 2(a + x) = 2[a + (a - x)] = 63

2(a + x) = 2(2x - x)

a + x = 2a - x

2a - a = 2x

a = 2x

x = $\frac{a}{2}$

Therefore, Perimeter = 2(a + x) = 2(a + $\frac{a}{2}$ ) = 63

$2\times \frac{3a}{2}$ = 63

3a = 63

a = 21

Therefore, measure of the sides of the square is 21 inches.

Sue set up a lemonade stand and sold 10 glasses of lemonade in the first hour. Her sales increased at the rate of 20% per hour f

KengaRu [80]

The appropriate exponential function for the first question is

... A: f(n) = 10 × 1.2^n

To find the revenue from sales of that many glasses, we multiply by the sale price to get

... B: 0.5(10 × 1.2^n)

Dad is twice as old as Jon. Grand-Pa is seven years older than three times Jon's age. The sum of their age is 145 years. How old

Alenkasestr [34]

Step-by-step explanation:

let jon age be x

dad age is 2 of x i.e 2x

grandpa age is 7 + 3(x)

The sum of jon dad and grandpa age is 145 i.e

x + 2x + (7+3x) = 145

3x +. 7 + 3x = 145

6x = 145- 7

6x = 138

divide both sides by 6

x = 23

jon age is 23

while

grandpa age is

7 + 3(x)

7 + 3(23)

7 + 69

76.
