6+7x=10x-12

then solve like normal

Answer:

240

Step-by-step explanation: 56 / 7 = 8

                                             30 * 8 = 240

Answer:

Area = 2x^2 + 14x + 24

Step-by-step explanation:

You could set up an expression (2x + 8) * (x + 3), where you multiply 2x by x, 2x by 3, 8 by x, 8 by 3, and then add them all up. 2x * x  = 2x^2, 2x * 3 = 6x, 8 * x = 8x, and 8 * 3 = 24. 2x^2 + 6x + 8x + 24 = 2x^2 + 14x + 24, so that is your answer.

Answer:

76°

Step-by-step explanation:

two parallel lines intersected by a transversal create several types of angle pairs - some of which are equal to each other, and some of which are supplementary

in this problem, ∠BCD ≅ ∠ BFG because they are 'corresponding'

therefore you can create this equation

x + 26 = 2x - 24

26 = x - 24

x = 50

substitute into '2x-24':  2(50) - 24 = 76

Answer:

425

Step-by-step explanation:

Answer: = (-2,3)

Step-by-step explanation:

Here, fixed point = origin = (0,0)

Transformation rule for rotation of  [tex]90^{\circ}[/tex]counterclockwise about the origin:

[tex](x,y)\to (-y,x)[/tex]

Then, the image of the point (3,2) =  (-2,3)

Hence, the image of the point (3,2) after a rotation of  [tex]90^{\circ}[/tex]counterclockwise about the origin = (-2,3)

Answer: The answer is -2,3 because 90 degrees of the orgin :) enjoy

Step-by-step explanation:

Answer:

the answer is A

Step-by-step explanation:

5x + 78 + 47= 180

solve for x

x=11

Answer: A) 11

Step-by-step explanation:

there are 180 degrees in a triangle. so, i added 47 and 78 together. that got me 125. i subtracted that from 180, in order to find the remaining angle.

it was 55 degrees, so i divided 55 by 5 in order to see what that was. whatever number that is was going to be x. it turned out to be 11.

hope this helps! xoxo

Answer:

The solution to the system of equations becomes:

(x, y) = (7, 12)

Step-by-step explanation:

Given the system of equations

[tex]5x - 3y = -1[/tex]

[tex]2x - y = 2[/tex]

Solving using the Elimination Method

[tex]\begin{bmatrix}5x-3y=-1\\ 2x-y=2\end{bmatrix}[/tex]

Multiply 5x - 3y = - 1 by 2:  10x - 6y = -2

Multiply 2x - y = 2 by 5:  10x - 5y = 10

[tex]\begin{bmatrix}10x-6y=-2\\ 10x-5y=10\end{bmatrix}[/tex]

subtraction operation

[tex]10x-5y=10[/tex]

[tex]-[/tex]

[tex]\underline{10x-6y=-2}[/tex]

[tex]y=12[/tex]

so the system of equations becomes

[tex]\begin{bmatrix}10x-6y=-2\\ y=12\end{bmatrix}[/tex]

Therefore, the value of y = 12

For 10x - 6y = -2 plug in y = 12

10x - 6y = -2

10x - 6(12) = -2

10x - 72 = -2

10x = -2+72

10x = 70

dividing both sides by 10

10x/10 = 70/10

x = 7

Therefore, the value of x = 7

Thus, the solution to the system of equations becomes:

(x, y) = (7, 12)

3, 700, 1.05.

Step-by-step explanation:

Answer:

3, 700, 1.05

Step-by-step explanation:

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Probability (P) is calculated as

P = [tex]\frac{number}{count}[/tex]

Since P(eclair) = [tex]\frac{1}{15}[/tex] and there are 3 eclairs, then original probability before simplification must have been

[tex]\frac{3}{45}[/tex]

meaning the total number of sweets is 45, so

3 + 2x + 6 + x = 45

3x + 9 = 45 ( subtract 9 from both sides )

3x = 36 ( divide both sides by 3 )

x = 12

Then number of humbugs = 2x + 6 = 2(12) + 6 = 24 + 6 = 30

P(humbug) = [tex]\frac{30}{45}[/tex] = [tex]\frac{2}{3}[/tex]

Answer:

13% decrease =  -13%

Step-by-step explanation:

Hey there

one example can be 70 decreased by 13%

so, first we find 13% of 70:

13% of 70 = 9.1

then we subract:

70 - 9.1 = 60.9

= 60.9

Answer:

Number 10 (8.70) 11 (9.57 12 (10.44) 13 (11.31)

Step-by-step explanation:

(11.31) pretty sure if not correct me

Answer:

(x, y) = (-6, -1)

Step-by-step explanation:

-2x + 6y = 6

y = 2x+11

By substituting the value of y (second equation) into the first equation, we get

-2x + 6(2x+11) = 6

-2x+12x+66 = 6

10x = -60

x = -6

So, y = -1

Answer:

x=4

Step-by-step explanation:

4x+10=26

Subtract 10 from both sides

4x=16

Divide by 4

x=4

answer: $11.40

explanation: turn the percent into a decimal, multiply it by the starting cost, then subtract the product from the starting cost

>> 40% = 0.40

0.40 x 19 = 7.60

19 - 7.60 = 11.40

You paid $11.4 for the shirt.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

A shirt costs $19 you buy it on clearance for 40% off.

You paid,

= 19 - (19 x 40 / 100)

= 19 - 7.6

= $11.4

Therefore, the amount is $11.4.

#SPJ2

Answer:16/20

Step-by-step explanation:  

if you divide the two numbers by 4 you have:

16/4=4

20/4=5

(if you divide or multiply both of the numbers with the same number, the ratio will remain the same)

So the two numbers are same

Answer:

3/4

Step-by-step explanation:

1 1/2 can be expressed as an improper fraction 3/2

hence

1 1/2 ÷ 2

= 3/2 ÷ 2

= 3/2 x 1/2

= 3/4

Step-by-step explanation:

7+3=10

Answer:

x > −3

Step-by-step explanation:

Let's solve your inequality step-by-step.

3(x + 2) > x

Step 1: Simplify both sides of the inequality.

3x + 6 > x

Step 2: Subtract x from both sides.

3x + 6 − x > x − x

2x + 6 > 0

Step 3: Subtract 6 from both sides.

2x + 6 − 6 > 0 − 6

2x > −6

Step 4: Divide both sides by 2.

2x / 2 > −6 / 2

x > −3

Answer:

x > −3
