dedylja [7]3 years ago
6 0

Answer:

We can make an equation

2 * 7x + 2 * 4x + 2 * 4 * 7 = 298

14x + 8x + 56 = 298

22x = 298 - 56

22x = 242

x = 242/22

x = 11

16. The weather report gives the temperature as 35 degrees Celsius. Find the
musickatia [10]

Answer:

F=95\°

Step-by-step explanation:

we know that

C=\frac{5}{9}(F\°-32)

In this problem we have

C=35\°

substitute the given value in the formula and solve for F

35\°=\frac{5}{9}(F\°-32)

F-32=\frac{9}{5}(35)

F=\frac{9}{5}(35)+32

F=95\°

(7,5), (r,9) m=6<br><br> What is r?
Igoryamba

Answer:

The answer is that r = 7/6

Step-by-step explanation:

Given point: (7, 5)

Given slope: m = 6

Use the point slope form of the equation:

y - y1 = m(x - x1)

y - 5 = 6(x - 7)

y - 5 = 6x - 7

y = 6x + 2

Now, find r for the point (r, 9) by substitution:

9 = 6x + 2

6x + 2 = 9

6x = 7

x = 7/6

Proof:

y = 6x + 2

f(x) = 6x + 2

f(7/6) = 6(7/6) + 2

= 42/6 + 2

= 7 + 2 = 9, giving (7/6, 9). r = 7/6

Hope this helps! Have a great day!
