Step-by-step explanation:

35.

the angles with x must be equal.

this is just a basic attribute of crossing lines. the crossing angles above and below a picked line are simply the same (just mirrored).

so,

8x + 7 = 9x - 4

11 = x

the angle with y is a complementary angle to either angle with x, as the sum of all angles in one side of a line is 180 degrees. let's pick 8x + 7

so,

7y - 34 + 8x + 7 = 180

7y - 34 + 8×11 + 7 = 180

7y + 61 = 180

7y = 119

y = 17

36.

similar here. just here the y angles are equal, and the x angle is complementary.

5y + 5 = 7y - 9

14 = 2y

y = 7

6x + 50 + 5y + 5 = 180

6x + 50 + 5×7 + 5 = 180

6x + 90 = 180

6x = 90

x = 15

Answer:

see explanation

Step-by-step explanation:

(35)

(9x - 4) and (8x + 7) are vertically opposite and are congruent , then

9x - 4 = 8x + 7 ( subtract 8x from both sides )

x - 4 = 7 ( add 4 to both sides )

x = 11

Then

8x + 7 = 8(11) + 7 = 88 + 7 = 95

(7y - 34) and 95 are adjacent angles on a straight line and sum to 180° , so

7y - 34 + 95 = 180

7y + 61 = 180 ( subtract 61 from both sides )

7y = 119 ( divide both sides by 7 )

y = 17

(36)

(7y - 9) and (5y + 5) are vertically opposite and are congruent , then

7y - 9 = 5y + 5 ( subtract 5y from both sides )

2y - 9 = 5 ( add 9 to both sides )

2y = 14 ( divide both sides by 2 )

y = 7

Then

5y + 5 = 5(7) + 5 = 35 + 5 = 40

(6x + 50) and 40 are adjacent angles on a straight line and sum to 180°

6x + 50 + 40 = 180

6x + 90 = 180 ( subtract 90 from both sides )

6x = 90 ( divide both sides by 6 )

x = 15

Solve for x. 1.1x + 1.2x - 5.4 = -10
Andru [333]

Answer:

x ≈  - 1.83

Step-by-step explanation:

to solve for x in the question 1.1x + 1.2x - 5.4 = -10

we have

2.3x - 5.4 = -10

collect the like terms

2.3x = -10 + 5.4

2.3x = -4.2

divide both sides by the coefficient of x

2.3x/2.3 = -4.2/2.3

x = -1.826

x ≈  - 1.83

Mario buys tickets for either 47 or 57 dollars. He purchases 14 tickets and spends 738 dollars. How many tickets did he purchase
Ivanshal [37]

Answer:

6 tickets were purchased at $47

8 tickets were purchased at $57

Step-by-step explanation:

Let the tickets purchased at $47 be x

Let the tickets purchased at $57 be y

We can form an equation from the question given which will be:

x + y = 14 ....... i

47x + 57y = 738 ........ ii

From equation i

x = 14 - y ........ iii

Substitute iii into ii

47x + 57y = 738

47(14-y) + 57y = 738

658 - 47y + 57y = 738

Collect like terms

-47y + 57y = 738 - 658

10y = 80

y = 80/10

y = 8

8 tickets were purchased at $57

Note that from i

x + y = 14

x + 8 = 14

x = 14 - 8

x = 6

6 tickets were purchased at $47

Fern rounded to the nearest ten to estimate 548-132. She subtracted 540-130 and got 410. Is Fern's estimate correct? Explain.
tensa zangetsu [6.8K]
Fern's estimate is not correct because he rounded 548 wrong, it would be rounded to 550 instead since the number 8 is closer to 10. So the correct answer would be 420.
