Step-by-step explanation:

Answer:

78

Step-by-step explanation:

Since the base angles are congruent, then the triangle is isosceles and

AB = BC , that is

5x - 19 = 2x + 11 ( subtract 2x from both sides )

3x - 19 = 11 ( add 19 to both sides )

3x = 30 ( divide both sides by 3 )

x = 10

Then

AB = BC = 2x + 11 = 2(10) + 11 = 20 + 11 = 31

Thus

perimeter = 31 + 31 + 16 = 78

Step-by-step explanation:

just multiply 6 by 2.25

Answer:

y = [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

Given

6y = 2 [tex]\frac{1}{4}[/tex] ← change into an improper fraction

6y = [tex]\frac{9}{4}[/tex] ( multiply both sides by 4 to clear the fraction )

24y = 9 ( divide both sides by 24 )

y = [tex]\frac{9}{24}[/tex] = [tex]\frac{3}{8}[/tex]

Answer:

x = 1

Step-by-step explanation:

1/2(8x-6) = -1/3(9x-12)   distribute

4x-3 = -3x+4                 add 3x to both sides

7x-3 = 4                        add 3 to both sides

7x = 7                            divide by 7 on both sides

x = 1

Answer:

$17.65

Step-by-step explanation:

First you have to subtract $7.65 from the total cost, $42.95.

Now, you have $35.30. Since she bought 2 DVD's, you have to divid $35.30 by 2.

Your answer is now $17.65, meaning that each DVD cost $17.65.

Answer:

I think she mowed 6 lawns.

Step-by-step explanation:

Answer:

1 lawn each week

Step-by-step explanation:

Rocco lawns mowed each week=x

Carly's lawns mowed each week=x+2

Equation to show how much Carly lawned for 6 weeks

18 is the total amount of lawns

6 is the number of weeks

6(x+2)=18

Solve for x

6x+12=18

Subtract 12 on both sides

6x=6

x=1

x is the amount that Rocco lawned

Answer:

⁴√16³ˣ

Step-by-step explanation:

16³/⁴ ˣ

The above can be expressed as follow:

16³/⁴ ˣ = 16³ˣ/⁴

Recall:

Aᵐ/ⁿ = ⁿ√Aᵐ

Therefore,

16³ˣ/⁴ = ⁴√16³ˣ

Thus, 16³/⁴ ˣ is equivalent to ⁴√16³ˣ

Answer:2 1 4 then 3

Step-by-step explanation:

The option (3) 0.03, 0.3, 0.35 represents the order from least to greatest. Option (3) is correct.

A number is a mathematical entity that can be used to count, measure, or name things. For an example, 1, 2, 56, 0.3 etc. are the numbers.

We have decimal number:

0.35, 0.3, 0.03

Here, the smallest number is 0.03

And the greatest number is 0.35

So,

The order from least to greatest:

0.03 > 0.3 > 0.35

Thus, the option (3) 0.03, 0.3, 0.35 represents the order from least to greatest. Option (3) is correct.

Answer:

  (f×g)(2) = 3/4

Step-by-step explanation:

For each of the functions, put 2 where x is and evaluate the expression.

  f(2) = (3 -2)/(2² +4) = 1/8

  g(2) = 3×2 = 6

Then the product is ...

  (f×g)(2) = f(2)×g(2) = (1/8)×6 = 6/8

  (f×g)(2) = 3/4

Answer:

easy (4)

Step-by-step explanation:

Answer:

finding slope: The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

parallel: We can determine from their equations whether two lines are parallel by comparing their slopes. If the slopes are the same and the y-intercepts are different, the lines are parallel. If the slopes are different, the lines are not parallel. Unlike parallel lines, perpendicular lines do intersect.

hope this helps!

Answer:

The slope of a line is the rise/run of how far away the points are from each other. Say you have the equation y=3/4x-6, the slope is 3/4 so that means you plot your first point at -6 on the y-axis, because that is your y-intercept, and then you will go up 3, right 4. You will continue to do this until you have enough points to make a line. When two lines are parallel, they will always have the same slope. So the lines y=1/2x+4 and y=1/2x-3 are parallel because not only do they have the same slope, they do not intersect at all, which is a requirement for parallel lines. I hope this helps!!
