Answer:

Use elimination, x = 6, y = 59

Step-by-step explanation:

1) Multiply Equation 1 by 2

E1: 4x +10y = 614

E2: 6x+10y = 626

2) Subtract E2 from E1

-2x = -12

x = 6

3) Substitute x = 6 into one of the equations (I used the original Equation 1)

2(6) +5y = 307

12+ 5y = 307

5y = 295

y = 59

Answer:

18.

Step-by-step explanation:

3 x 6 = 18. He eats 3 slices every 5 minutes so 5 minutes x 6 is half an hour. so 18 is your answer.

If Takaya continues to eat three slices of pizza in five minutes, he could eat 18 slices in half of an hour.

The Linear equation in one variable is an algebraic equation of degree one.

it can be expressed in the form of Ax +B = 0 where x is a variable, and A and B are two integers.

Takaya can eat three slices of pizza in five minutes.

for half an hour it would be 6 times five minutes.

So, in half an hour Takaya can eat 3 × 6 = 18

Therefore, If Takaya continues to eat three slices of pizza in five minutes, he could eat 18 slices in half of an hour.

Answer:

  1386 miles

Step-by-step explanation:

The plane flies ...

  (150 mi/h)(1.6 h) = 240 mi

on its first leg. Then it flies ...

  (150 mi/h)(9.1 h) = 1365 mi

on the second leg. The flight directions differ by 90°, so the distance from the starting point can be found using the Pythagorean theorem.

  c² = 240² +1395² = 1920825

  c = √1920825 ≈ 1385.94

The plane is about 1386 miles from its starting point.

Answer:

[tex]H_o:\mu = 26[/tex]

[tex]H_a:\mu < 26[/tex]

Step-by-step explanation:

Given

Average score is less than 26

Required

Determine the null and alternate hypothesis

Since the average is said to be less than 26; that represents the alternate hypothesis.

The null hypothesis will be:

[tex]Average = 26[/tex]

So, we have:

[tex]H_o:\mu = 26[/tex]

And the alternate hypothesis

[tex]H_a:\mu < 26[/tex]

Alright.

For 7, you'll want to put congruent sides equal to each other, assuming they are parallelograms. So, you'll get the two equations:

3x+2=23

2y-7=9

Solve using GEMDAS/PEMDAS, and you'll get these answers.

3x+2=23

3x=21

x=7

2y-7=9

2y=2

y=1

For 8, you'll want to do the exact same thing, formatting the numbers to equal each other. You'll get these two equations:

3y+5=14

2x-5=17

Solving them would make:

3y+5=14

3y=9

y=3

2x-5=17

2x=22

x=11

For 9, you have to remember that the angle opposite of one angle in a defined parallelogram are congruent. Thus:

130=2h

5k=50

solve them and you get

h=65

k=10

Answer:

7.) y=8, x=7

8.) y=3, x=11

9.) h=65, k=10

Step-by-step explanation:

First, let's start with #7. By definition of a parallelogram, we can say that opposite sides are congruent, meaning 2y-7=9 and 3x+2=23.

So, solving these problems-

2y-7=9

2y=16

y=8

3x+2=23

3x=21

x=7

Now, let's move on to #8. For this, a defining property of a parallelogram is that the diagonals bisect each other. So, 3y+5=14 and 2x-5=17.

Let's solve these equations-

3y+5=14

3y=9

y=3

2x-5=17

2x=22

x=11

Now, finally #9. Another defining property of a parallelogram is that opposite angles are congruent. So, 2h=130 and 5k=50.

So, h= 65 and k= 10.

Step-by-step explanation:

edg 2021 .. its correct

The equation that is graphed along with the parent function is [tex]g(x)=\sqrt[3]{x-3} +4[/tex]

The parent function is a cube root function, represented as:

[tex]f(x) = \sqrt[3]{x}[/tex]

First, the parent function is horizontally shifted right by 3 units

The rule of this transformation is:

[tex](x,y) \to (x - 3,y)[/tex]

So, we have:

[tex]f'(x) = \sqrt[3]{x - 3}[/tex]

Next, the transformed function is vertically shifted up by 4 units

The rule of this transformation is:

[tex](x,y) \to (x,y+4)[/tex]

So, we have:

[tex]g(x)=\sqrt[3]{x-3} +4[/tex]

Hence, the equation is [tex]g(x)=\sqrt[3]{x-3} +4[/tex]

I hope it helps.........

The missing angle ∠ABC is 35°.

Let the missing angle be x and y To find the missing angle y, we need to solve the equation 102° + x + y = 180, where x and y are angles.

Given that x + 137 = 180, we can substitute the value of x in terms of 180 - 137:

x = 180 - 137

x = 43°

Now, we can substitute the value of x into the equation y =∠ABC  

102° + x + y = 180

102° + 43° + y = 180

Combining like terms:

145° + y = 180

To find y, we subtract 145° from both sides:

y = 180 - 145

y = 35°

Therefore, the missing angle ∠ABC is 35°.
