Answer:

13/16

Step-by-step explanation:

(1/8) + (5/16) + (3/8) =

The denominator 8 goes into 16 twice so multiply the top and bottom numbers by 2

(1 x 2) + (5/16) + (3 x 2)

(8 x 2) (8 x 2)

2/16 + 5/16 + 6/16 = 13/16

I hope this helps!

Erin is 8 years younger than twice Paula’s age. The sum of their ages is 40. How old is Erin

Lina20 [59]

You do the sum(40) subtracted by 8, the answer from that divided by 2 since Erin's two times younger.
40-8=32
32÷2=16
Then if you want to check it you do the opposite and get the same sum(40) so 16×2=32 and 32+8=40

Given f(x) and g(x) = k⋅f(x), use the graph to determine the value of k.

ollegr [7]

Answer:

k=5

Step-by-step explanation:

step 1

Find the equation of the line f(x)

we have the points

(-4,0) and (-2,2)

<em>Find the slope m</em>

$m=(2-0)/(-2+4)\\m=1$

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=1\\(-4,0)$

substitute

$y-0=(1)(x+4)$

$y=x+4)$

Remember that

f(x)=y

$f(x)=x+4$

step 2

Find the equation of the line g(x)

we have the points

(-4,0) and (-2,-10)

<em>Find the slope m</em>

$m=(10-0)/(-2+4)\\m=5$

Find the equation of the line in point slope form

$y-y1=m(x-x1)$

we have

$m=5\\(-4,0)$

substitute

$y-0=(5)(x+4)$

$y=5(x+4)$

Remember that

g(x)=y

$g(x)=5(x+4)$

Remember that

$g(x)=kf(x)$ ------> $g(x)=5(x+4)$

therefore

k=5

Subtract 8 from 5 times a number. The result is 4 less than 3 times the number.

vovikov84 [41]

Answer: x =2

Step-by-step explanation:

5x - 8 = 3x - 4

2x = 4

x = 2

checking the work:

5(2) - 8 = 3(2) - 4

10 - 8 = 6 - 4

2 = 2
