What is 3x+70=8x-20 show work
Elena-2011 [213]

Answer:

Hi there!

Your answer is:

x= 18

Step-by-step explanation:

3x+70=8x-20

Isolate x on left side

3x+70=8x-20

-8x       -8x

-5x +70 = -20

Isolate whole numbers on right side

-5x +70 = -20

      -70      -70

-5x = -90

Isolate x by dividing both sides by -5

-5x = -90

/-5

x= 18

ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions
ryzh [129]

Answer:

The third option is correct.

The domain of the function is given by

Domain = 0 \leq t \leq 40

The range of the function is given by

Range = 0 \leq V(t) \leq 200

Step-by-step explanation:

Sara bought a cell phone for $200 and its value has decreased at rate of $5 per month.

V(t) is the value of the phone and t is the number of months.

The domain of the function is the possible values of the number of months t.

The domain of the function is given by

Domain = 0 \leq t \leq 40

The range of the function is the values of V(t) that we get after substituting the possible values of the number of months t.

The range of the function is given by

Range = 0 \leq V(t) \leq 200

When the number of months is t = 0 then the value of the function is maximum V(t) = 200

When the number of months is t = 40 then the value of the function is minimum V(t) = 0

Therefore, the third option is correct.

Malachai is doing a 20 miles bike ride. He has cycled 11 miles so far. What percentage of the the total distance has he cycled
Anestetic [448]
11 miles / 20 miles =.55
.55 x 100 = 55%
11/20 is the proportion and you multiply by 100 to gey a percent
another way to solve is
11/20 x 5/5 = 55/100 = 55%
you multiply by 5/5 because it is equal to one and it makes the denominator equal to 100 it also follows the rule that whatever you do to the top you must do with the bottom

Write an inequality for the given graph.
Aliun [14]
Y=MX+B

M = slope

B = y intercept (number that intersects with the line in the y axis)

y=-3/4x+2

It starts on the y intercept (2) then we travel to the next point (4 on the x axis)

So we travel 3 spaces down (-3) landing on the origin (0,0) then four spaces to the right (4). Getting the slope of -3/4 (rise over run)

Then just plug in these into the equation

y = -3/4 + 2
