cos S = $\frac{7}{25}$

Step-by-step explanation:

this is a 7- 24- 25 right angle with RS = 7 , then

cos S = $\frac{adjacent}{hypotenuse}$ = $\frac{RS}{QS}$ = $\frac{7}{25}$

X/13 - 1 = 5x/2 + 1/2 please answer the question pls pls pls pls

Morgarella [4.7K]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

the given expression can be solved as follows ~

$\frac{x}{13} - 1 = \frac{5x}{2} + \frac{1}{2} \\$

taking LCM both the sides ,

$\frac{x - 13}{13} = \frac{5x + 1}{2} \\$

on cross multiplying ,

$(x - 13)2 = (5x + 1)13 \\ \\ \implies \: 2x - 26 = 65x + 13$

let's now gather the like terms at either sides of the equation ~

$65x - 2x = - 26 - 13 \\ \\ \implies \: 63x = - 39 \\ \\ \implies \: x = \frac{\cancel{ - 39}}{\cancel{63}}$

on simplifying the equation ,

$\implies \frac{-13}{21}\\$

hope helpful ~

Mickey's bowling score is 16 less

Tpy6a [65]

Mickey's bowling score is 167 and Minnie's bowling score is 61

Step-by-step explanation:

The given is:

1. Mickey's bowling score is 16 less than 3 times Minnie's score

2. The sum of their scores is 228

We need to find the score of each one

Assume that the score of Minnie is x

∵ Minnie's score = x

∵ Mickey's score is 16 less than 3 times Minnie's score

- That means subtract 16 from 3 times Minnie's score

∴ Mickey's score = 3 x - 16

∵ The sum of their scores is 228

- Add their scores and equate the sum by 228

∴ x + 3 x - 16 = 228

- Add like terms in the left hand side

∴ 4 x - 16 = 228

- Add 16 for both sides

∴ 4 x = 244

- Divide both sides by 4

∴ x = 61

Substitute the value of x to find their scores

∵ Minnie's score is x

∴ Minnie's score = 61

∵ Mickey's score is 3 x - 16

∴ Mickey's score = 3(61) - 16 = 167

Mickey's bowling score is 167 and Minnie's bowling score is 61
