Answer:

a = 3/2 b​

Step-by-step explanation:

7a - 2b =5a + b​

Subtract 5a from each side

7a-5a - 2b =5a-5a + b

2a -2b = b

Add 2b to each side

2a-2b+2b = b+2b

2a = 3b

Divide each side by 2

2a/2 = 3b/2

a = 3/2 b​

Answer:

A

Step-by-step explanation:

We have the system of equations:

-3x + 4y = -22

2x + 7y = 5

Let's solve this using elimination, so multiply the first equation by 2 and the second equation by 3:

2 * (-3x + 4y = -22)  ⇒  -6x + 8y = -44

3 * (2x + 7y = 5)  ⇒  6x + 21y = 15

Our equations are now:

-6x + 8y = -44

6x + 21y = 15

Add these two together to eliminate the x term:

    -6x + 8y = -44

+    6x + 21y = 15

______________

     0x + 29y = -29

y = -29/29 = -1

Plug this back into one of the equations to find x:

-3x + 4y = -22

-3x + 4 * (-1) = -22

-3x - 4 = -22

-3x = -18

x = -18/(-3) = 6

The answer is (6, -1) or A.

Answer:

A. (6,-1)

Step-by-step explanation:

-3x + 4y = -22

2x + 7y = 5

x = (5 - 7y)/2

-3[(5 - 7y)/2] + 4y = -22

-15/2 + 21y/2 + 4y = -22

29y/2 = -29/2

y = -1

x = (5 - 7(-1))/2

x = 12/2

x = 6

Answer: 108

Step-by-step explanation: You take the x and the 2/3x and combine them to get 1 2/3x, so 1 2/3x=180. 180 divided by 5 is 36, and 36 times three is 108

Answer:

108

Step-by-step explanation:

Angles on a line add up to 180 degrees.

x + 2/3x = 180

5/3x = 180

x = 180 × 3/5

x = 108

Answer:

$346.00

Step-by-step explanation:

We know that the price to take a plane to the Island of Mysteries is $600 and the price to take a boat is $254.

To find how much money they will save if they were to take a boat, you would subtract the cost of the boat ride from the plane ride to find the difference.

$600 - $254 = $346.00

Step-by-step explanation:

we have been given an expression [tex]\frac{\frac{2}{3}}{-4}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]. We are asked to simplify our given expression.

Using quotient rule [tex]\frac{\frac{a}{b}}{c}=\frac{a}{bc}[/tex], we will get:

[tex]\frac{2}{3\cdot -4}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]

[tex]\frac{2}{-12}-\left(\frac{1}{6}-\frac{8}{6}\right)[/tex]

Now, we will combine like terms:

[tex]\frac{2}{-12}-\left(\frac{1-8}{6}\right)[/tex]

[tex]\frac{2}{-12}-\left(\frac{-7}{6}\right)[/tex]

[tex]-\frac{2}{12}+\frac{7}{6}[/tex]

[tex]-\frac{1}{6}+\frac{7}{6}[/tex]

Let us combine like terms:

[tex]\frac{-1+7}{6}[/tex]

[tex]\frac{6}{6}=1[/tex]

Therefore, our expression simplifies to 1.

Answer: [tex]x=6[/tex]

Subtract 2x from both sides

[tex]8x-72-2x=2x-36-2x\\6x-72=-36[/tex]

Add 72 to both sides

[tex]6x-72+72=-36+72\\6x=36[/tex]

Divide both sides by 6

[tex]6x/6=36/6\\x=6[/tex]

Answer:

x=6

Step-by-step explanation:

first thing first you always need to get x alone and since you have an X on both side we need to move one of them to the same side as the other one.

8x-72=2x-36

add 72 on both sides ( the opposite of subtracting is adding)

8x=2x-36+72  

8x=2x+36

then we subtract 2x on both sides to get X alone

8x-2x=36

6x=36

then we divide 36 by 6 to get our answer for x

X= 6

Answer:

In option a, w < 10

in option b, w = 10 and 2(20) + 2(10) = 40 + 20 = 60 < 150

in option c, w > 10 but 2(60) + 2(20) = 120 + 40 = 160 > 150

In option d, w > 10 but 2(55) + 2(30) = 110 + 60 = 170 > 150

Therefore the corect answer is option b.

We have been given that in ΔIJK, the measure of ∠K=90°, KJ = 77, IK = 36, and JI = 85. We are asked to find the ratio that represents the cosine of angle I.

First of all, we will draw a right triangle as shown in the attachment.

We know that cosine relates adjacent side of right triangle with hypotenuse.

[tex]\text{cos}=\frac{\text{Adjacent}}{\text{Hypotenuse}}[/tex]

We can see that adjacent side to angle I is IK and hypotenuse is IJ.

[tex]\text{cos}(\angle I)=\frac{IK}{IJ}[/tex]

[tex]\text{cos}(\angle I)=\frac{36}{85}[/tex]

Therefore, the ratio of cosine of angle I is [tex]\frac{36}{85}[/tex].

Answer:

x=−1 y=4

Step-by-step explanation:

Let's solve your system by substitution.

2x−5y=−22; x+7y=27

Rewrite equations:

x+7y=27;2x−5y=−22

Step: Solve x+7y=27for x:

x+7y=27

x+7y+−7y=27+−7y(Add -7y to both sides)

x=−7y+27

Step: Substitute−7y+27 for x in 2x−5y=−22:

2x−5y=−22

2(−7y+27)−5y=−22

−19y+54=−22(Simplify both sides of the equation)

−19y+54+−54=−22+−54(Add -54 to both sides)

−19y=−76

−19y

−19

=

−76

−19

(Divide both sides by -19)

y=4

Step: Substitute 4 for y in x=−7y+27:

x=−7y+27

x=(−7)(4)+27

x=−1(Simplify both sides of the equation)
