The third one is a point with the first equation.

I had to simplify the second equation.

It simplified to,

$y = - \frac{1}{4} x - 2$
The second one with the above is didn't go through so I'd say no solution.

What is the next number? 2+3=8 3+7=27 4+5=32 5+8=60 6+7=72 7+8=?

ale4655 [162]

Answer:

Step-by-step explanation:

2 + 3 = 8

8 : 2 = 4; 4 - 1 = 3 (subtract 1)

3 + 7 = 27

27 : 3 = 9, 9 - 2 = 7 (subtract 2)

4 + 5 = 32

32 : 4 = 8; 8 - 3 = 5 (subtract 3)

5 + 8 =60

60 : 5 = 12, 12 - 4 = 8 (subtract 4)

6 + 7 = 72

72 : 6 = 12, 12 - 5 = 7 (subtract 5)

7 + 8 = x

x : 7 = y, y - 6 = 8 (subtract 6)

Solve:

y - 6 = 8 add 6 to both sides

y - 6 + 6 = 8 + 6

y = 14

x : 7 = y ⇒ x : 7 = 14 ⇒ x = (14)(7) ⇒ x = 98

the perimeter of a rectangle is 55 inches. the ratio of the length to width is 7:4. use proportions to find the area of the rect

Leni [432]

Answer:

Step-by-step explanation:

let : x the length and y the width .... ( x > y and x ; y reals numbers )

the perimeter is : 2(x+y)

2(x+y) = 55...(1)

x/y = 7/4 ...(2)

by (2) : x = (7/4)y

subsct in (1) : 2( (7/4)y +y ) =55

(7/2)y +2y =55

multiply by 2

7y +4y = 110

11y = 110

y = 10

x = (7/4)(10)

x = 35/2

An objects weight on Mars is 38% of its weight on Earth. If an object weighs p, pounds on Earth, write an expression for its wei

oksano4ka [1.4K]

0.38p

To get the percent of something, you turn the percent to a decimal and multiply it to the number.

Here, we want the expression to get 38% of p. So we turn 38% to 0.38 and multiply it to p. Since we don't know what p is, we have to leave it as 0.38p

The answer is 0.38p

Hope this helps!
