2.5x - 3 + 2x = 1.75x - 1.25x + 13

4.5x - 3 = 0.50x + 13

4.0x = 16

x = 4

Answer: 4

2. We'll assume those xs are in the numerator

(3/7)x - 1/4 + (3/7)x = (9/7)x - (3/7)x + 3/4 - 1

(6/7)x - 1/4 = (6/7)x  - 1/4

0 = 0

That's always true.

Answer: Any x is a solution.

amm1812

The easy answer: If, say, B is the zero matrix, i.e.

B=\begin{bmatrix}0&0\\0&0\end{bmatrix}

then

2A=\begin{bmatrix}5&0\\-1&2\end{bmatrix}\implies A=\begin{bmatrix}\dfrac52&0\\\\-\dfrac12&1\end{bmatrix}

Please Help simple problem for 30 points<br><br>Telling me / showing work will get you brainy
Norma-Jean [14]

Answer:

Step-by-step explanation:

Start with the circumference.

C = 2*pi*r

C = 301.5

pi = 3.14

r = ??

Solution

301.5=3.14 * 2 * r

301.5 = 6.28*r

r = 301.5/6.28

r = 48.01

So the radius = 48.01

The diameter is twice as much or 48.01 * 2 = 96.02
