Expand the brackets on the right side so,,

12x + 20 = 6x + 24

Collect like terms and place the x’s on one side and the numbers on one side ,,

6x = 4

Divide both sides by six to get x alone,,

X= 6/4

X = 1.5

Answer:

Step-by-step explanation:

Formula

$B = 25(\frac{M}{10} +\frac{3}{4} )$

Where M meters of granola makes B granola bars.

Given:

M = 2.5 meters

Now substitute that value in the formula and calculate.

$B=25(\frac{2.5}{10} +\frac{3}{4} )= 25(1) = 25$

Therefore, 2.5 meters of granola makes 25 granola bars.

B = 25

Ron earned 13200 in interest on an account with a principal amount of 24000 and an interest rate of 11%. How long were the funds

lord [1]

Answer:

5 years

Step-by-step explanation:

It is assumed the interest is simple.

Use the interest formula:

I = Prt

We have:

I = 13200
P = 24000
r = 11% = 0.11

Substitute values and solve for t:

13200 = 24000*0.11t
13200 = 2640t
t = 13200/2640
t = 5 years

Answer:

$\cot \theta = \frac{8}{15} \\\\\sec \theta = \frac{17}{8} \\\\\csc \theta = \frac{17}{15}$

Step-by-step explanation:

$\huge \tan \theta = \frac{15}{8} ...(given) \\ \\ \huge \because \: \cot \theta = \frac{1}{ \tan \theta} \\ \\ \huge \therefore \: \cot \theta = \frac{1}{ \frac{18}{8} } \\ \\ \huge \therefore \: \cot \theta = \frac{8}{15} \\ \\ also \\ \huge \sec \theta = \frac{17}{8} \\$
