If the sum of base angle of isosceles triangle
is 88° calculate the other angle​

Answer:

bus = 50mph and train = 70mph

Step-by-step explanation:

4b + 4t = 480

t = b + 20 [replace the "t" in the next step to solve]

4b + 4(b + 20) = 480

4b + 4b + 80 = 480

8b + 80 = 480 [subtract 80 from both sides of the equation]

8b = 400 [divide by 8 on both sides of the equation]

b = 50 and if the train is 20mph faster, t = 70

4(50) + 4(70) = 480

Answer:

480

Answer:

3

Step-by-step explanation:

To find the slope of a line going through two points, (x₁, y₁) and (x₂, y₂), we can use the following formula: [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]. Note that it doesn't really matter which points we call (x₁, y₁) or (x₂, y₂).

Let's call (x₂, y₂) = (0, 5) and (x₁, y₁) = (-2, -1). Now, we can plug in the values for x, y₁, x₂, and y₂ into the formula.

We have:

[tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }=\frac{5-(-1)}{0-(-2)} =\frac{5+1}{0+2} =\frac{6}{2} =3[/tex]

Therefore, the slope of the line is 3. Hope this helps!

Answer:

-3a-4b+5

Step-by-step explanation:

(3a-6b+12)-(6a-2b+7)

3a-6b+12-6a+2b-7

3a-6a-6b+2b+12-7

-3a-4b+5

Answer:

The equation becomes

[tex]1\frac{7}{19}=a\frac{b}{c}[/tex]

Therefore,

Hence, option (C) is true.

Step-by-step explanation:

Given the expression

[tex]3\frac{1}{4}\div 2\frac{3}{8}\:=a\frac{b}{c}[/tex]

Solving the L.H.S of the equation

[tex]3\frac{1}{4}\div \:2\frac{3}{8}=\frac{13}{4}\div \:2\frac{3}{8}[/tex]

               [tex]=\frac{13}{4}\times \frac{8}{19}[/tex]

               [tex]=\frac{13\times \:2}{1\times \:19}[/tex]

                [tex]=\frac{26}{1\times \:19}[/tex]

                 [tex]=\frac{26}{19}[/tex]

Converting improper fraction to a fixed number: [tex]\frac{26}{19}=1\frac{7}{19}[/tex]

                 [tex]=1\frac{7}{19}[/tex]

Thus, the equation becomes

[tex]1\frac{7}{19}=a\frac{b}{c}[/tex]

Therefore,

Hence, option (C) is true.

Answer:

-3/10

Step-by-step explanation:

3/2 is equivalent to 15/10. Or 1 5/10. And 6/5 is equivalent to 18/10s or 1 8/10. Therefore 1 1/5 + (-1 8/10) = -3/10

Answer:

8/27 lb

Step-by-step explanation:

The salad has 1/3 of 8/9 lb.

1/3 * 8/9 = 8/27

Answer: 8/27 lb

Answer:

3+2w=l

2(l+w)=7 1/3

2(3+2w+w)= 7 1/3

6+6w= 7 1/3

-6 both sides

6w=1 1/3

/6 both sides

w=2/9

2/9*2=4/9+3=3 4/9

4/9*3 4/9= 1 43/81

1 43/81

Answer:

[tex]\large\boxed{\pink{ \leadsto The \ given \ equation \ is \ not \ a \ Quadratic \ equation . }}[/tex]

Step-by-step explanation:

Given equation to us is ,

[tex]\green{\implies x^2+\dfrac{1}{x}=4 }[/tex]

So , a equation is said to be a quadratic equation if the highest degree of the variable is 2 . On simplifying the Equation ,

[tex]\implies x^2 +\dfrac{1}{x}=4 [/tex]

Taking x as LCM ,

[tex]\implies \dfrac{x^2.x + 1 }{x}= 4 [/tex]

Transposing x to RHS .

[tex]\implies x^3 + 1 = 4x [/tex]

Putting all terms in LHS

[tex]\boxed{\bf \implies x^3 - 4x - 1 = 0 }[/tex]

Since here the highest degree of the variable is 3 not 2 . So its a cubic equation and not a quadratic equation .

Answer:

Option (3)

Step-by-step explanation:

Given inequality is,

-2x + 8 < 12

By subtraction property of Order,

-2x + 8 - 8 < 12 - 8

-2x < 4

B division property of Order,

[tex]\frac{-2x}{(-2)}<\frac{4}{(-2)}[/tex]

x > -2

Since, there is no sign of equal to ( = ) in the given inequality, starting point on a number line will be a hollow point.

And an arrow starting from point x = -2 directing towards positive integers will represent the given inequality.

Option (3) will be the answer.

Answer:

103

Step-by-step explanation:

bassically what you do is add 7 dollars to the ninety six that she lost when she bought the pie or you can do this equation 96 + m but m would be the money she lost being 7 dollars so you would replace m with 7 so it would be 96 + 7 = 103
