1. 5 + x = -2



2. 8m = 48

Solve this problems giving brainliest


Answers

Answer 1

Answer: 1. x=-7 2. m=6

Step-by-step explanation:

1. 5 + x=-2

to get the x by itself, you need to subtract 5 from both sides

5-5 +x = -2-5

there for 0 + x = -7 which means x=-7

2. to get 8m to just m, you need to divide 8m by 8. and what you do to one side of the equation, you need to do to the other. therefore 8m/8=48/8 and 48/8=6. therefore m=6

Answer 2

Answer:

1. 5+x=-2

x=-2-5

x= -7

2. 8m=48

m= 48/8

m= 6

you are driving to a friends house at 35 miles per hour and the friend lives 21 miles away. how long to get to the house

Answers

Answer:

35miles/1 hr=21miles/x hr

= x hr* 35miles/1 hr= 21 miles

= x = 21/35 =0.6 hr

So, traveling at 35mph it will take 0.6 hours to travel 21 miles.

If you want time in mins then keep going:

=> 60 mins = 1 hour, 0.6 hours = x mins

60mins/1 hr = x mins/ 0.6 hr

0.6 * 60 mins = 36 mins.

:. It takes 0.6 hrs or 36 mins to drive 21 miles at a constant speed of 35mph

Find a, R, and T.

Answers

a = 4, R = 147, T = 33

Step-by-step explanation:

find a

a/(a + 7) = (16/3)/(44/3)

a/(a + 7) = 16/44

44a = 16a + 112

44a - 16a = 112

28a = 112

a = 112/28

a = 4

find R

2x + 5 = 3x - 9

5 + 9 = 3x - 2x

14 = x

m ∠R = 180° - (2x + 5)

= 180 - (2(14) + 5)

= 180 - (28 + 5)

= 180 - 33

= 147°

find T

m ∠T = 3x - 9

= 3(14) - 9

= 42 - 9

= 33°

Aright triangle has leg lengths of 7 centimeters and 24 centimeters.
What is the length of the triangle's hypotenuse?

Answers

Use the pythagorean theorem.

A^2 + b^2 =c^2
=
49+576=c^2
625=c^2
c= sqrt 625
c=25

Answer:

25 centimeters

Step-by-step explanation:

We can use the Pythagorean Theorem to find the length of a missing side of a right triangle

Pythagorean Theorem: a² + b² = c²

where a and b = legs and c = hypotenuse

For the following problem we are given two legs and need to find the hypotenuse, to do so we simply plug in the length of the legs and solve for the hypotenuse  or "c"

Leg lengths = 7 and 24

So a = 7 and b = 24

So we plug in 7 and 24 for a and b and solve for c

a² + b² = c²

a = 7

b = 24

(7)² + (24)² = c²

simplify exponents

49 + 576 = c²

add 59 and 576

625 = c²

take the square root of both sides

√625 = 25

√c² = c

we're left with c = 25

So the length of the hypotenuse would be 25 centimeters

A triangle has sides with lengths of 17 inches, 20 inches, and 28 inches. Is it a right triangle?

Answers

Answer:

no

Step-by-step explanation:

Pythagoras theorem

a2 + b2 = c2

the hypotenuse side is always the longest so its 28

:

[tex]17 { }^{2} + 20 ^{2} = 28 ^{2} [/tex]

289+ 400 =784

689 = 784

so the triangle is not a right angled triangle

Which table represents a linear function?

Answers

Answer:Well, a linear function is proportional, a straight line (on a graph). And the numbers must not have the same answer. For instance, if the X input is 5, and the Y output is 7. And then another X input is 5, and the Y output is 8, that's non-linear.

So, the Answer would be the third graph. This is because the X values are steadily increasing, and so are the Y values.

For the X and Y values, for each time X increases by 1, Y increases by -8. This is, linear because both sides are constantly and evenly increasing.

Answer:

angle 4 = 56°

Step-by-step explanation:

Interior angles in the same side of the transversal are supplementary (their sum is 180°)

Angle 1 and 4 are interior angles on the same side of the transversal.

So, angle 1 + angle 4 = 180°

Angle 1 = 124° (given)

124 + angle 4 = 180°

angle 4 = 180° - 124° = 56°

Therefore, angle 4 = 56°

Gretel wept bitterly and spoke to Hansel: "Now its all up with us. "No, no, Gretel, said Hansel, "dont fret yourself; Ill be able to find a way of escape, no fear. And when the old people had fallen asleep he got up, slipped on his little coat, opened the back door, and stole out. The moon was shining clearly, and the white pebbles which lay in front of the house glittered like bits of silver. Hansel bent down and filled his pocket with as many of them as he could cram in.

His father observed him, and [said]: "Hansel, what are you gazing at there, and why do you always remain behind? Take care, and dont lose your footing.
