x + 2 = 30

Answers

Answer 1

Answer:

x + (x + 2) = 30

Step-by-step explanation:

Number of Pennies = x

Number of Nickels = x + 2

Total = 30

x + (x +2) = 30

find the midpoint of the segment with the endpoints (-2,-6) and (8,8)

Answers

Answer:

(3,7)

Step-by-step explanation:

no time thank you

Answer:

The midpoint of the segment with points (-2,-6) and (8,8) is (3,1).

What is the midpoint?

The midpoint of a line segment is known as the midpoint in geometry. It is the centroid of the segment and of the ends, and it is equally distant from both of them. It cuts the section in half.

The given points are ( -2,-6) and (8,8). The formula to calculate the midpoint is given below:-

Midpoint = ( x₁ + x ₂ ) / 2 , ( y₁ + y₂ ) / 2.

Midpoint = ( -2 + 8 ) / 2 , ( -6 + 8 ) / 2

Midpoint = (3,1)

Therefore, the midpoint of the segment with points (-2,-6) and (8,8) is (3,1).

what is 2(1+5x)-3x=72 solve for x please

Answers

Answer:

x = 10

Step-by-step explanation:

2(1+5x)-3x=72

Distribute

2 + 10x -3x = 72

Combine like terms

2+7x=72

Subtract 2 from each side

2+7x-2 = 72-2

7x = 70

Divide by 7

7x/7 = 70/7

x = 10

Step-by-step explanation:

x+6y=-2

6y=-2-x

y=-1/6x-1/3

Solve the system of equations by substitution.

y = 4x -1

2x + 2y = 3

Answers

Step-by-step explanation:

y = 4x - 1

2x + 2y = 3

2x + 2(4x - 1) = 3

2x + 8x - 2 = 3

10x = 3 + 2

x = 5/10

x = 1/2

y = 4x - 1

y = 4(1/2) - 1

y = 2 - 1

y = 1

Answers

Answer:

5 miles

Step-by-step explanation:

We are looking at triangles LCM and OGM.

Point M is the midpoint of segments LO and CG.

That makes segments CM and GM congruent (side).

Then angles CML and GMO are congruent since they are vertical angles (angle).

Finally, segments LM and OM are also congruent because of the midpoint (side).

By SAS, triangles LCM and OGM are congruent.

Then by CPCTC, segments LC and OG are congruent.

Since OG = 5 miles, then LC = 5 miles.

Answers

Answer:

3. m1=82, m4=59. m5=98, m6=51, m7=79, m9=51, m10=129

4. m1=36, m2=90, m4=36, m5=90, m6=54, m7=126, m8=54, m9=126, m10=54, m11=36, m12=144, m13=36, m14=144

Step-by-step explanation:

3. m2=98, m3=23, m8=70

by supplementary angles, m1 + m2 = 180, since we know m2, we have m1 = 180 - 98 = 82. by corresponding angles we have m1 = m3 + m4, since we know m1 and m3, we have m4 = 82 - 23 = 59. again by supplementary angles, m3 + m4 + m5 = 180. we know m3 and m4 so m5 = 180 - 23 - 59 = 98. by alternate interior angles m4 = m7, so m7 = 59. by supplementary angles m6 + m7 + m8 = 180 so m6 = 180 - 70 - 59 = 51. by corresponding angles m6 = m9 so m9 = 51. by supplementary angles m9 + m10 = 180 so m10 = 129

4. m3=54

m2 is a right angle so m2=90. by complementary angles m3 + m4 = 90 so m4 = 36. by vertical angles m1=m4 so m1=36. by vertical angles m2=m5 and m3=m6 so m5=90 and m6=54. by corresponding angles m7 = m2+m1 so m7=126. by supplementary angles m7+m8 = m7+m10 = 180 so m8=10=54. by vertical angles m7=m9 so m9=126. by corresponding angles m1=m11 and m3=13 so m11 and m13 = 54. by supplementary angles m12+m13= m11+m14 = 180, so m12 = m14 = 144

<( not the writeing part UGH!!

Inequalities that have the same solution are called equivalent. There are properties of inequalities as well as there were properties of equality. All the properties below are also true for inequalities involving ≥ and ≤. The addition property of inequality says that adding the same number to each side of the inequality produces an equivalent inequalit. The subtraction property of inequality tells us that subtracting the same number from both sides of an inequality gives an equivalent inequality. The multiplication property of inequality tells us that multiplication on both sides of an inequality with a positive number produces an equivalent inequality. Multiplication in each side of an inequality with a negative number on the other hand does not produce an equivalent inequality unless we also reverse the direction of the inequality symbol. The same goes for the division property of inequality.Division of both sides of an inequality with a positive number produces an equivalent inequality.And division on both sides of an inequality with a negative number produces an equivalent inequality if the inequality symbol is reversed.To solve a multi-step inequality you do as you did when solving multi-step equations. Take one thing at the time preferably beginning by isolating the variable from the constants. When solving multi-step inequalities it is important to not forget to reverse the inequality sign when multiplying or dividing with negative numbers.

ASAP: Write a Summary of the story "The Brave Little Parrot" 50 points if interested!!Passage: Once, long ago, the Buddha was born as a little parrot. One day a storm fell upon his forest home. Lightning flashed, thunder crashed, and a dead tree, struck by lightning, burst into flames. Sparks leapt on the wind and soon the forest was ablaze. Terrified animals ran wildly in every direction, seeking safety from the flames and smoke."Fire! Fire!" cried the little parrot. "To the river!" Flapping his wings, he flung himself out into the fury of the storm and, rising higher, flew towards the safety of the river. But as he flew he could see that many animals were trapped, surrounded by the flames below, with no chance of escape.Suddenly a desperate idea, a way to save them, came to him. He darted to the river, dipped himself in the water, and flew back over the now raging fire. The heat rising up from the burning forest was like the heat of an oven. The thick smoke made breathing almost unbearable. A wall of flames shot up on one side, and then the other. Crackling flames leapt before him. Twisting and turning through the mad maze of fire, the little parrot flew bravely on. At last, when he was over the center of the forest, he shook his wings and released the few drops of water which still clung to his feathers. The tiny drops tumbled down like jewels into the heart of the blaze and vanished with a hissssssssss.Then the little parrot once more flew back through the flames and smoke to the river, dipped himself in the cool water, and flew back again over the burning forest. Back and forth he flew, time and time again, from the river to the forest, from the burning forest to the river. His feathers were charred. His feet were scorched. His lungs ached. His eyes, stung by smoke, turned red as coals. His mind spun dizzily as the spinning sparks. But still the little parrot flew on.At this time, some of the devasgods of a happy realmwere floating overhead in their cloud palaces of ivory and gold. They happened to look down. And they saw the little parrot flying among the flames. They pointed at him with perfect hands. Between mouthfuls of honeyed foods they exclaimed, "Look at that foolish bird! He's trying to put out a raging forest fire with a few sprinkles of water! How absurd!" And they laughed.But one of those gods, strangely moved, changed himself into a golden eagle and flew down, down towards the little parrot's fiery path.The little parrot was just nearing the flames again when the great eagle with eyes like molten gold appeared at his side. "Go back, little bird!" said the eagle in a solemn and majestic voice. "Your task is hopeless! A few drops of water can't put out a forest fire! Cease now and save yourselfbefore it is too late."But the little parrot only continued to fly on through the smoke and flames.
