Answer 1

Answer:

68.50 in

Step-by-step explanation:

first we are given the width and the length for the rectangle and so we know that 4 × 5x + 7 = 128

so we would now solve for x:

4 × 5x + 7 = 128

= 4 × 5x = 121

= 20x = 121

= x = 6.05

now we can plug in 6.05 for x and find the perimeter:

5(6.05) + 4 = 34.25

34.25 + 34.25 = 68.50

Mary is buying tickets for a movie.
• Each adult ticket costs $9.
• Each child ticket costs $5.
• Mary spends $110 on tickets.
• Mary buys 14 total tickets.
How many adult tickets, and how many child tickets, does she buy?
Please explain your work! I will mark brainliest if you do :)

Answers

adult ticket = 10

child ticket = 4

Step-by-step explanation:

for example…

adult ticket = xchild ticket = y

so that we get a system of equations

9x + 5y = 110…Equation 1

x + y = 14…Equation 2

solve the system of equations, this time I will use the Elimination and Substitution method

9x + 5y = 110

x + y = 14 (multiplied by 5)

↓↓↓↓↓↓↓

9x + 5y = 110

5x + 5y = 70

___________ _

4x = 40

x = 10

to find value of y subtitute x to one of Equation. for example from second Equation…

x + y = 14

10 + y = 14

y = 14 - 10

y = 4

∴ So, the number of each ticket was she bought is 10 adult ticket and 4 child ticket.

Answer:

x = 85°

y = 85°

Step-by-step explanation:

The sum of angles in a triangle are 180°

So 29 + 66 + x = 180

Solve for x:

180 = 29 + 66 + x

Subtract 29 and 66 from both sides

85 = x

x = 85°

_______________________________________

x = y because they are vertical angles, and are congruent.

Since x is 85°, y = 85° as well

-Chetan K

Answer:

X= 85

Y= 85

Step-by-step explanation:

All angles in a triangle add up to 180.

Because we are given two of the angles of this triangle, we can solve for X.

180= 29+66+X

Therefore,

X= 180-29-66

X= 85

To solve for Y:

if two angles are diagonal from each other with no other lines intersecting the angle (as seen in this example), then the two diagonal angles are equal.

In this example, X is diagonal to Y

Therefore,

X=Y

X=85

Y=85

7/8 - 4/5 what is the answer to this thing because i don't know it at all duhhhh

Answers

7/8-4/5. When subtracting two fractions, we must have a common denominator. A common denominator is a factor in which goes into both 8 and 5.

1.) Common factor: 45. 45 goes into and 8 and 5. If we list out all the factors of 8 and 5, 45 will be the lowest common factor.

2.) We need to multiply by a number to get 45 for each denominator. We can a one-step equation to figure out what we need to multiply 8 by and 5 by to get 45.
X=the factor of 8 that will get us 45.
8x=45
8x/8=45/8
x=5.625.
Y=factor of 5 that will get us 45.
5y=45
5y/5=45/5
y=9.

3.) We now know that we need to multiply 8 by 5.625 and 5 by 9 in order to get 45 as the denominator for both fractions.
7/8x5.625-4/5x9
7/45-4/45.

4.) Whatever is done to the denominator must be done to the numerator.
7x5.625/45-4x9/45
39.375/45-36/45

5.) We now have common denominators, so we simple subtract the numerators ONLY. We DO NOT subtract the denominators.
39.375/45-36/45=3.375/45.

Therefore, 3.375/45 is your answer.

Then u use the sum product pattern

4(6x^2-11x+3)

Then find the common factor for both pairs

4(6x^2-2x-9x-3)

Then rewrite in factor form
