Solve this equation 3x - 5 = -26

Dmitry_Shevchenko [17]

3x - 5 = -26

step 1:

subtract +5 on each side because you have to do the inverse operation

step 2:

3x= -21

step 3:

now divide 3 on each side

the answer is -7

Hope this helped!

jorge was tracking the decreasing temperature in the morning. at 7 a.m. it was 65 degrees fahrenheit. at 9 a.m. it was 55 degree

if at 7 it was 65 and at 9 it was 55, that means temperature is decreasing by 5 per hour

When p = 12, t = 2, and s = One-sixth, r = 18. If r varies directly with p and inversely with the product of s and t, what is th

bagirrra123 [75]

Answer:

$k = \frac{1}{2}$

Step-by-step explanation:

Given

$p = 12$

$t = 2$

$s = \frac{1}{6}$

$r = 18$

$r\ \alpha\ p\ * \frac{1}{s * t}$

Required

Find the constant of variation

From the question, the variation is as follows

$r\ \alpha\ p\ * \frac{1}{s * t}$

$r\ \alpha\ \frac{p * 1}{s * t}$

$r\ \alpha\ \frac{p}{s * t}$

Convert variation to equation

$r\ = k\frac{p}{s * t}$

Where k represents the constant of variation

Make k the subject of formula;

Multiply both sides by s * t

$r * s * t = k\frac{p}{s * t} * s * t$

$r * s * t = kp$

Divide both sides by p

$\frac{r * s * t}{p} = \frac{kp}{p}$

$\frac{r * s * t}{p} = k$

$k = \frac{r * s * t}{p}$

Substitute the values of p, r, s and t in the above equation

$k = \frac{18 * \frac{1}{6} * 2}{12}$

$k = \frac{6}{12}$

Divide numerator and denominator by 6

$k = \frac{1}{2}$

Hence, the constant of variation is; $k = \frac{1}{2}$

What is 5/8 + 3/4 because I am doing fractions right know

pantera1 [17]

$\frac{5}{8} + \frac{3}{4} =$

So, $\frac{5}{8} + \frac{3}{4} * \frac{2}{2} = \frac{5}{8} + \frac{6}{8} = \frac{11}{8}$

Simplified as mixed number equals to $1 \frac{3}{8}$

(Keep in mind that the LCM was 8.)
