Plug 10 in for y.

10=2x-2.5

Add 2.5 to both sides.

12.5=2x

Divide both sides by 2.

6.25=x

Hope this helps! :)

Your answer would be 6.25.

When finding the answer to this equation, you will insert 10 where 'y'' is in the equation. 10= 2x - 2.5. Then you want to have x alone on one side, so you need to add 2.5 to 10. 12.5= 2x. Once you did this, divide 12.5 by 2 and you have your answer. 12.5/2= 6.25

Answer:

V = 27.16inch^3

Step-by-step explanation:

Find the radius = 8/2 = 4

V=4/3 π r3

V=4/3 π * 4 x 4 x 4

V=4/3 π * 64

V = 4/3 π = 0.42441318157 = π +1/3 Take this and multiply to 64

0.42441318157 x 64 = 27.1624436205 = 27.162444

V = 27.16inch^3

Please show the work

Step-by-step explanation:

15t + 30 = 20t | -15t

30 = 5t

t = 30/5 = 6

20 + 5t = -6t + 86 | + 6t

20 + 11t = 86 | -20

11t = 66

t = 6

18t + 20 = 24t + 50 | -18t

20 = 6t + 50 | -50

-30 = 6t

t = -30/6 = -5

18t - 2 = 10t + 54 | -10t

8t - 2 = 54 | +2

8t = 56

t = 56/8 = 7

7t - 5 = 15t + 91 | -7t

-5 = 8t + 91 | -91

-96 = 8t

t = -96/8 = -12

What is (5x + 3z) +9z simplified

Alex17521 [72]

5x+12z Because you take, 3z+9z and that is equivalent to 12z. and then you put the 5x back into the equation so it is 5x+12z

The expressions are not equivalent even though Ella got the same result when she substituted zero for f.

<h2>→ <u>Explanation :-</u></h2>

$\sf{When \: zero:}$ $\sf{2f \: + \: 2.6 = 3f \: + 3.6}$

$\sf{the \: rest \: is \: equal}$

$\sf{but \: when \: one: \: 2 \: + \: 2.6}$ $\sf{\: 3 \: + \: 3.6}$

$\sf{4.5 \: + \: 5.6}$

$\sf{is \: not \: equal}$

$\sf{such \: as \: 2, \: 3, \: 4, \: 5...}$

$\sf{is \: not \: equal}$
