Answer:

8, 40 , 50

Step-by-step explanation:

the measure of A is 90°

so 5x + 7x - 6 = 90

now.. to find the x

5x + 7x - 6 = 90

5x + 7x = 90 + 6

12x = 96

x = 96/12

x = 8

so the measure of angle A1 is (5*8) = 40

the measure of angle A2 is (7*8-6) = 50

finaly the angle A is (50+40) = 90

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 ~

Which has the same value as 5/8 ÷2.. A 5/8 × 2/1. b. 8/5 ×2/1 . c5/8 ÷2/1. .d.5/8 × 1/2

Kisachek [45]

Answer:

5/8 x 1/2

Step-by-step explanation:

To change division into multiplication, you must find the reciprocal by flipping the second fraction (note that if it is a whole number, as in this case, it is technically over 1).

(5/8)/(2/1) = (5/8)(1/2)

d. is your answer.

Q19. Look at the image.

Neko [114]

Answer:

It's C

Step-by-step explanation:

Because if you look at the other numbers they all add up to the next number by 4. 4+4=8 8+4=12 12+4=16 16+4=20 20+4=24

Therefore, x intercept is 24 and y intercept is 18. Hope this is correct if it's not correct then I'm very sorry. Have a nice day. ;)

sergiy2304 [10]

Answer:

$c(x)=(x+3)^2+5$

Step-by-step explanation:

$c(x)=x^2 + 6x + 14 = x^2+6x+9 + 5 = (x+3)^2+5$
