Question 5
Write the equivalent expression by combining like terms.
-5x + 2y + 3x

plssss rn 45 POINTS

Answer:

40

Step-by-step explanation:

The total area of the garden is  31.75 sq meters

The first step is to calculate the radius if the circle

The diameter of the garden is 20 feet

2π × radius= 20

2π × 3.14= 20

6.28π= 20

π= 20/6.28

π= 3.18

The area of the flower garden can be calculated as follows

= π × radius²

= 3.14 × 3.18²

= 3.14 × 10.1124

= 31.75 sq meters

Hence the total area of the garden is 31.75 sq meters

Answer:

The answers are 54 degrees and 234 degrees

Step-by-step explanation:

mathematically we have the tan positive on only two axes

these are the first (0-90) degrees and the 3rd quadrant (180-270)

We start by find the arc tan of the angle value

Thus;

x = arc tan (1.3562)

x = 54 degrees

On the third quadrant, we have it that;

180 + 54 = 234 degrees

Answer:

The original price was $875.

Step-by-step explanation:

a = p * w

630 = 72% * w

630 / 0.72 = $875

$875 should be the original price, I hope this helps!

Answer:

When rotating a point 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x). This means, we switch x and y and make x negative.

Answer:

105 degrees

Step-by-step explanation:

supplementary angles equal 180 so 180-75=105

Answer:

The first triangle is because right triangles are tilted on a 90 degree angle

A solution to a quadratic is the same as the root or x intercept (when talking about real numbers). The graph shows that we have exactly one x intercept, which is where the parabola touches the x axis. So we have one root.

Answer:

Adult ticket is $6

Student ticket is $4, as you said.

Step-by-step explanation:

We'll call adult tickets x and student tix y.

14x + 11y = 128

14x + y = 88

First, solve the second equation for y in terms of x:

y = 88- 14x

Then substitute that for y into the first equation:

14x + 11(88-14x) = 128

14x + 968 - 154x = 128

-140x = -840

x = 6  The adult ticket is $6, like you said.

Now take that and solve for y:

y = 88 - 14(6)

y = 88 - 84

y = 4 The student ticket is $4, as you said.

Hope this helps. Feel free to ask questions so you can understand.

Answer: 4

Step-by-step explanation:

Change the 2.5 to an improper fraction, then multiply by the reciprocal of 5/8.

[tex]2\frac{1}{2} /\frac{5}{8} =\frac{5}{2}*\frac{8}{5}=\frac{40}{10} =4[/tex]

Conversion a mixed number 2 1/

to a improper fraction: 2 1/2 = 2 1/

2

= 2 · 2 + 1/

= 4 + 1/

= 5/

To find new numerator:

a) Multiply the whole number 2 by the denominator 2. Whole number 2 equally 2 * 2/

2

= 4/

b) Add the answer from previous step 4 to the numerator 1. New numerator is 4 + 1 = 5

c) Write a previous answer (new numerator 5) over the denominator 2.

Answer:

y=7x-6

Step-by-step explanation:

You would first pick two coordinates in this case would be ( 0, -6), (1,1). You would find your slope by using the formula y2-y1/x2-x1. Which would give you a slope of 7/1 which is equal to 7. Then you would use point slope formula which is y-y1=m(x-x1). would would plug in the numbers and it would say

y-(-6)=7(x-0). Then you would simplify the y-(-6) which would be y+6 then you would distribute the 7. Your whole equation would look like y+6=7x+0. Then you would use inverse operations and subtract -6 from the left side of the equals and subtract it from 0 giving you -6. Therefore your whole equation would be y=7x-6. Hoped this helped.
