Answers

Answer 1

Answer:

Step-by-step explanation:

10). AD = BC [If ABCD is a parallelogram]

     3x + 1 = 6x - 4

     6x - 3x = 1 + 4

     3x = 5

     x = [tex]\frac{5}{3}[/tex]

11). If ABCD is a parallelogram,

     AB = CD

     5x - 8 = 2x + 7

     5x - 2x = 7 + 8

     3x = 15

     x = 5

12). If ABCD is a parallelogram,

     AB = CD

     AB║CD and BD is a transversal intersecting these parallel lines.

     ∠ABD ≅ ∠BDC [Alternate interior angles]

     4x - 1 = x + 38

     4x - x = 38 + 1

     3x = 39

     x = 13

Help! Find the measure of each angle indicated

Answers

Answer:

40 degrees

Step-by-step explanation:

Answer should be 40. Vertical angles dictate that it should be 36. Then if you find the full like with the 76, the other part is 104. Add 104 and 36, which gets you 140. A triangle is 180, so you subtract 140 from 180 and get 40.

Sorry about the handwriting I tried. But I need help

Answers

I don’t know much but all triangles add up to 180 so half of the triangle is 45, 45, and a 90 degree angle, adding these 3 numbers add to 180

The perimeter of a rectangle is 42 inches. If the width of the rectangle is 6 inches, what is the length?
reminder: perimeter is distance around an object- length + width + length + width

12 inches

15 inches

21 inches

40 inches

Answers

Answer:

15 inches

Step-by-step explanation:

42 = 2L + 2(6)

first, we need to isolate L.

solve 2(6) to make this easier

42 = 2L + 12

42 - 12 = 2L + 12 - 12 ( this cancels out 12. )

30 = 2L

30 ÷ 2 = 2L ÷ 2 ( this cancels out 2. )

15 = L

Select the correct answer.
The slope of the function on the left is multiplied by p, and is added to the yIntercept to arrive at the function on the right. Which of the
following are the values for p and q?
A. p = -2 and q = -2
В. p=-2 and q = -4
C. P = 2 and q = -3
D. P = -2 and q = -3

Answers

Answer:

p = -2

q = -3

Step-by-step explanation:

Let us get the equation of the two graphs

General equation form is;

y = mx + b

m is slope and b is the y-intercept

For the first one;

y intercept is 1

So the equation is;

y = mx + 1

The x-intercept is -2

the value of y at the x-intercept is 0

0 = -2m + 1

1 = 2m

m = 1/2

so;

1/2 * p

p/2

q added to y-intercept;

q + 1

Let us get the equation of the second plot

y-intercept is -2

Equation is;

y = mx - 2

We can get slope using x-intercept

x-intercept is -2

0 = -2m - 2

2m = -2

m = -1

So;

p/2 = -1

p = 2 * -1 = -2

For the value of q;

q + 1 = -2

q = -2-1 = -3

Answer:

[tex] \huge \boxed {x = 1}[/tex]

Step-by-step explanation:

Both bases are the same so you will be able to solve the equation from exponent and exponent.

[tex]2x - 3 = - 2x + 1 \\ 2x + 2x = 1 + 3 \\ 4x = 4 \\ x = 1[/tex]

Answer Check

Substitute x = 1 in the equation.

[tex] {6}^{2(1) - 3} = {6}^{ - 2(1) + 1} \\ {6}^{2 - 3} = {6}^{ - 2 + 1} \\ {6}^{ - 1} = {6}^{ - 1} [/tex]

Both are same each sides. Therefore the equation is true.

c = grocery store charges

Tax is 8% added to the charges.

Which expression shows the total charges with tax?

A. 1.8c
B. 1.08c

Answers

B because it is in the 10ths place

The total charge with tax will be 1.08c.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Grocery store charges = c

And, Tax is 8% added to the charges.

Now,

Since, Tax is 8% added to the charges.

Hence, The total charge with tax = c + 8% of c

                                                   = c + 8/100 × c

                                                   = c + 0.08c

                                                   = 1.08c

Thus, The total charge with tax = 1.08c.

I need help. I have been searching for the answer but I cannot find the correct one. Elena rode her bike 2 miles in 10 minutes and 1 mile in 5. How many miles if it only took her 1 minute? Like how many miles would she have rode in 1 minute?

Answers

Answer:

0.2 miles

Step-by-step explanation:

From the above question:

2 miles = 10 minutes

Hence:

10 minutes = 2 miles

1 minute = x miles

Cross Multiply

10 minutes × x miles = 2 miles × 1 minute

x miles = 2 miles × 1 minute/10 minutes

x miles = 0.2 mile

Hence in 1 minute it would take her 0.2 miles
