What’s the answer to 1.9m + 14 = 2m?

joja [24]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{m = 140}}}}}$

Step-by-step explanation:

$\sf{1.9m + 14 = 2m}$

Move 2m to right hand side and change it's sign

Similarly, move 14 to left hand side and change it's sign

$\dashrightarrow{ \sf{1.9m - 2m = - 14}}$

Collect like terms

$\dashrightarrow{ \sf{ - 0.1m = - 14}}$

Divide both sides by -0.1

$\dashrightarrow{ \sf{ \frac{ - 0.1m} { - 0.1} = \frac{ - 14}{ - 0.1}}}$

Calculate

$\dashrightarrow{ \sf{m = 140}}$

Hope I helped!

Best regards! :D

1. The quadratic parent function f(x) = x2 was transformed to

AlekseyPX

Answer:

Step-by-step explanation:

Given f(x) then f(x + a) is a horizontal translation of f(x)

• If a > 0 then a shift left of a units

• If a < 0 then a shift right of a units

The graph of g(x) is the graph of f(x) shifted 6 units left , then

g(x) = f(x + 6) → C

the side length of the state flag of Colorado are in the ratio of 2:3 if the flag is 12 ft long what is the height?

yanalaym [24]

Answer:

The height is 8

Step-by-step explanation:

Ratios are just fractions. That being said, you also have part of a fraction. You know that the colorado flag is in 2:3, and 12 feet long is according to that ratio; it equals each other.

Make the equation.

$\frac{2}{3} = \frac{x}{12}$

Now isolate x (in order to solve for it)

$12 * \frac{2}{3} = \frac{x}{12}*12\\8 = x$

x= 8

The height is 8.

8/12 = 2/3 ✅
