10m + -0.4 = 9.6
-0.4 + 10m = 9.6
-0.4 + 10m = 9.6
Solving for 'm'Move all terms containing m to the left, all other terms to the right.
-0.4 + 0.4 + 10m = 9.6 + 0.4
Combine like terms: -0.4 + 0.4 = 0.00.0 + 10m = 9.6 + 0.410m = 9.6 + 0.4
Combine like terms: 9.6 + 0.4 = 1010m = 10

Answer:

m = 1

Step-by-step explanation:

10m - 2/5 = 9 3/5

10m = 9 3/5 + 2/5

10m = 9 + 5/5

10m = 9 + 1 = 10

10m = 10

m = 1

Solve the following exponential growth function for y when x=5. round to the nearest tenth
OlgaM077 [116]

Here the given expression is

y =1.5^x

And the given value of x=5 . We need to find the value of y when x=5. And for that, we need to plug 5 for x .

y=1.5^5 =7.6

So when x=5, y= 7.6

a rhombus as an area of 72 ft and the product of the diagonals is 144. What is the length of each diagonal?
SashulF [63]

A = (1/2)(x)(y)

Let x = diagonal 1

Let y = diagonal 2

The product of xy = 144.

This means that x = 12 and y = 12.

So, 12 • 12 = 144

Each diagonal is 12 feet.

Prove:

72 feet = (1/2)(12)(12) feet

72 feet = (1/2)(144) feet

72 feet = 72 feet

Should it be facing left or right ?
riadik2000 [5.3K]

Answer:

Facing Right

Step-by-step explanation:

Given inequalities are:

4-x≤-1

Subtracting 4 from both sides

4-x-4≤-1-4

-x≤-5

Multiplying both sides with -1. Multiplying with a negative number changes the sign of the inequality

So,

x≥5

Second Inequality:

2+3x≥17

Subtracting 2 from both sides

2+3x-2≥17-2

3x≥15

Dividing both sides by 3

x≥5

Union of both solutions:

x≥5 ∩ x≥5

=> x≥5

Hence the solution will be facing right on the number line towards all numbers greater than or equals to 5 ..

If 16+4x is 10 more than 14, what is the value of 8x?
sattari [20]
16 + 4x = 10 + 14

16 + 4x = 24.

4x = 24 - 16

4x = 8

x = 8 ÷ 4

x = 2

8x = 2 × 8

8x = 16

Final answer = 16.
