Answer:

2x + 66 + x = 180

3x = 180 - 66

3x = 114

x = 38

Answer: x=38 degrees

Step-by-step explanation:

You know that a line is equal to 180 degrees.

You equation -                           2x+x+66=180

Solve .                                        3x+66=180

Subtract 66 from both sides     3x = 114

divide                                            x=38

Given Jessica and Laura's expenditure on shirts and pants, the equation to solve for the price of each shirts and pants is:

3s + 4p = 90

4s + 2p = 70

Let

Cost of each shirts = s

Cost of each pants = p

Jessica:

3s + 4p = 90 (1)

Laura:

4s + 2p = 70 (2)

Multiply (2) by 2

8s + 4p = 140 (3)

8s + 4p = 140 (3)3s + 4p = 90 (1)

Subtract (1) from (3) to eliminate p

8s - 3s = 140 - 90

5s = 50

s = 50/5

s = $10

substitute s = 10 into (1)

3s + 4p = 90 (1)

3(10) + 4p = 90

30 + 4p = 90

4p = 90 - 30

4p = 60

p = 60/4

p = $15

Therefore, the cost of each shirts is $10 and the cost of each pants is $15

The equation that match the table attached is

B. y = -5(2⁻ˣ) + 4

By analyzing the given equations we can see that option B match the table and this is shown below

Using calculator to set the equation shows that

for x = -2

y = -5(2⁻ˣ) + 4 = 2.75

for x = -1

y = -5(2⁻ˣ) + 4 = 1.5

for x = 0

y = -5(2⁻ˣ) + 4 = -1

for x = 1

y = -5(2⁻ˣ) + 4 = -6

Based on the comparison, the equation that corresponds to the table is:

OB.y = -5(2⁻ˣ) + 4

Therefore, the correct option is OB.

Given quardratic polynomial is 3x^2+(2k-5)x-7

On Comparing this with the standard quadratic Polynomial ax^2+bx+c

a = 3

b=2k-5

c = -7

Given zeroes α and -α

sum of the zeroes α +(-α) = -b/a

⇛ α +(-α) = -(2k-5)/3

⇛ 0 = -(2k-5)/3

⇛ 0×3 = -(2k-5)

⇛0 = -(2k-5)

Using the similarity of triangles, it exists seen that the true equation exists given by:

A) a/b = c/d

Two triangles exist similar when they have the same angles. Then, the measurements of the sides adjacent to similar angles exist proportional.

In this problem, about the location of the right angle of the triangle, we have that:

a/c = b/d

a/b = c/d

Therefore, the correct answer is option A) a/b = c/d.

Answer:

1600=50x+100(thats the equation) ACTUAL ANSWER: X=30

Step-by-step explanation:

The inequality represents all possible values of x, which will be 1600=50x+100.

Linear inequalities involve at least one linear algebraic expression. A polynomial of degree 1 is compared to another algebraic expression of degree less than or equal to 1.

The greatest weight a moving truck can carry = is 1,600 pounds

Weight of the piano = 400 pounds

Weight of box = 50 pounds

The inequality represents all possible values of x will be;

1600 = 50x+100

Hence the inequality represents all possible values of x, the number of these boxes that can be loaded into the moving truck will be 1600=50x+100.
