X + 2 = 5x + 26<br><br> Please help
kkurt [141]
x+2=5x+26

Move all the x's to one side of the equation. This is a step necessary to solve this equation.

Subtract both sides by x.

x+2-x=5x+26-x
2=4x+26

Flip equation. We always want to have the variable written on the left side.

4x+26=2

Subtract both sides by 26.

4x+26-26=2-26
4x=-24

Divide both sides by 4 to finish this off.

x=-6

That's your answer. Have an awesome day! :)

Trey drove 250 miles using 9 gallons of gas. At this rate, how many gallons of gas would he need to drive 275 miles?
GarryVolchara [31]

Answer:

10 gallons of gas.

Step-by-step explanation:

250/9 = how many miles 1 gallon of gas will take

250/9 = 27.78

1 gallon of gas = 27.78 miles

275/27.78 = 9.90 gallons

9.90 gallons round up to 10 gallons

Therefore, Trey would need 10 gallons of gas to drive 275 miles.

Consider Frank's math test scores for the semester. Find the interquartile range of the scores.
musickatia [10]
Okay so you put the numbers in order:
70, 74, 81, 82, 83, 91, 94.

Then you find the median which will be Q2:
82.

Once you have the total median, you find the midpoint of the first and last part:
70, 74, 81. Midpoint/Q1=74
83, 91, 94. Midpoint/Q3=91

Now that you have that, you subtract Q3 and Q1.
91-74=17

17 is your IQR.

Evaluate the trigonometric ratio​
vfiekz [6]

Answer:

1

Step-by-step explanation:

Given \lim_{x \to 0} \frac{sinxcosx}{x}

multiply the numerator and denominator with 2

we get \lim_{x \to 0} \frac{2sinxcosx}{2x}

We know that sin2x=2sinxcosx

\lim_{x \to0} \frac{sin2x}{2x}

Now consider y=2x

As x→0 2x→0 y→0

Now limit changes to

\lim_{y \to0} \frac{siny}{y}=1
