1..) 2x +15 = 35 

Mathematics
1 answer:
Masja [62]3 years ago
3 0

Answer:

1) x=10

2) x=3

Step-by-step explanation:

1)

2x+15=35

Subtract 15 from both sides

2x=20

Divide both sides by 2

x=10

2(10)+15=35

20+15=35

35=35

this shows that 10 is the right answer

2)

7x-3=18

Add 3 to both sides

7x=21

Divide both sides by 7

x=3

7(3)-3=18

21-3=18

18=18

this shows that 3 is the right answer

Hope this helps

Can someone pls help me with this !

Using a line of best fit, the predicted tsunami speed for the following depths is given by:

a. 1151 km/h.

b. 572 km/h.

c. 130 km/h.

d. 122 km/h.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (depth, velocity) are given by:

(7000, 943), (4000, 713), (2000, 504), (200, 159), (50, 79), (10,36)

Inserting these points in the calculator, the velocity in function of the depth is:

v(d) = 0.12879d + 121.03448

Hence, the velocities are given as follows:

a. v(8000) = 0.12879 x 8000 + 121.03448 = 1151 km/h.

b. v(3500) = 0.12879 x 3500 + 121.03448 = 572 km/h.

c. v(70) = 0.12879 x 70 + 121.03448 = 130 km/h.

d. v(5) = 0.12879 x 5 + 121.03448 = 122 km/h.

What is the value of n? n–2= 10n+ 4/2 Enter your answer in the box.
pentagon [3]

Answer:

-4 / 9

Step-by-step explanation:


 n - 2 = 10n + 4/2

 n - 10n = 4/2 + 2

 -9n = 4/2 + 4/2 ( taking LCM of 4/2 and 2)

 -9n = 8/2

 -9n = 4

    n = 4 / -9

   

   therefore n = -4 /9 ( since the minus sign doesn't make a difference whether placed at numerator or denominator) .
