Given the expression 18+9*4-27+9

Using PEMDAS method

P is for parenthesis

E is for exponents

M is for multiplication

18+(9*4)-27+9

= 18+36-27+9

Next is Addition

= (18+36)-(27+9)

= 54-36

Then Subtraction

= 54-36

= 18

Hence the required value is 18

Parallel and Perpendicular Lines. When you graph two or more linear equations on the coordinate plane, they usually intersect at some point. However, when two lines in a coordinate plane never intersect, they are called parallel lines.

Brad buys a sandwich. The regular cost is $6. He uses a coupon for 10% off. After that deduction, a sales tax of 5% is added. How much money Brad need to pay for the sandwich?
A. $5.10
B. $5.67
C. $5.94
D. $6.93

Answers

A is the answer to that

The answer is B.

5% of 6.00 = 0.4

6.00 - 0.60 = $5.40

10% of 5.40 = 0.27

5.40 + 0.27 = $5.67

Question A construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River. Use h the formulat to find how many seconds it takes for the hammer to reach the river. Round your answer to the 4. nearest tenth of a second. s

Answers

Answer:15.8

Step-by-step explanation:

After 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

A construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

The equation is:

t = √h/4

Plug h = 4000 ft

t = √4000/4

After solving:

t = 15.81 seconds

Thus, after 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

Answers

Answer: x=2 and y=−1

Step-by-step explanation:

5x+7y=3for x:

5x+7y=3

5x+7y+−7y=3+−7y(Add -7y to both sides)

5x=−7y+3

x= −7/ 5 y+ 3 /5

Substitute −7 /5 y+ 3 /5 for x in2x+3y=1:

2( −7/ 5 y+ 3 /5 )+3y=1

1 /5 y+ 6 /5 =1(Simplify both sides of the equation)

1 /5 y= −1 /5

y=1

Substitute −1 for y in x

−7 /5 y+ 3 /5 : x=

x=2

x=2(Simplify both sides of the equation)

find for x

Answers

Answer:

120°

Step-by-step explanation:

The angle next to the x will be 40° due to the alternate angles so

x + 40° + 20° = 180° { being linear pair }

x + 60° = 180°

x = 180° - 60°

x = 120 °

Hope it will help :)

Answer:

120˚

Step-by-step explanation:

Since the two lines are parallel, they are alternate angles

So that means that the angle next to x must be 40˚

So 40 + 20 + x = 180 (since it's half a circle)

60 + x = 180

x = 120

becky spends 3/5 of her money she has left £60 left. how much money did she start with?

Answers

Answer: $150

Step-by-step explanation:

Hence 2 parts = $60

And 5 parts = $150

Becky has $150 at first.

Becky starts with $150.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Becky spends 3/5 of her money she has left £60 left.

let Becky earned be x.

so, x- 3/5x= 60

2x/5 = 60

x= 300/ 2

x=$150

Hence, Becky starts with $150.
