Answer 1

Answer:

X=12

Step-by-step explanation:

Isolate the variable:

4x/4 = 48/4

Simplify:

X=12

Hope this helps!

Answer 2

Answer:

x = 12

Step-by-step explanation:

Step one: Inverse the equation to eliminate the coefficient*.

*The coefficient is the number or variable that multiplies another variable (associated with it). In this case, it is four that is the coefficient.

48/4 = 12

x = 12

Check for answer:

4*12 = 48

The answer is x = 12.

Hope this helped. Have a great day.

solve the equation to find the missing leg of the right triangle

x2+0.5 squared=1.3 squared

Answers

Answer:

1.2

Step-by-step explanation:

x2 is the missing leg so the formula to find the missing leg to a right triangle is

c squared- b squared=a squared which in this case would be

1.3 ^2 - 0.5^2 = x^2 ( ^ means squared)

1.69 - 0.25 = x^2

[tex]\sqrt{x}[/tex]1.44 = 1.2

1.2 = missing leg

Answer:

option B

Step-by-step explanation:

-2(4 - 3x) + (5x - 2)=

-8+6x+5x-2= 11x -10

-8 + 6x + 5x - 2 and 11x-10 are the equivalent expressions of the given expression -2(4 - 3x) + (5x - 2)

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is -2(4 - 3x) + (5x - 2)

We have to find the equivalent expression

x is the variable in the expression

Equivalent expressions are expressions that work the same even though they look different.

Let us apply distributive property

-8+6x+5x-2

Combine the like terms

11x-10

Hence, -8 + 6x + 5x - 2 and 11x-10 are the equivalent expressions of the given expression -2(4 - 3x) + (5x - 2)

Answer:

753.982236862

Step-by-step explanation:

1) Cut Cylinder in half, perpendicular to the circle face. Effectively making a rectangle face. The Pencil diagnolly reaching from the top corner to the bottom corner act like a divider which splits the rectangle into 2 triangles. Which allows for us to use Pythagorem theorem.

pythagorean theorem: [tex]c^2=a^2+b^2}[/tex]

The Pencil is 17cms long. So [tex]17^{2}[/tex]=[tex]{a^2+b^2}[/tex]

the height is 15cms long. So [tex]17^{2}[/tex]=[tex]15^2+b^2}[/tex]

We need to Solve for B, so we will subtract A from C since C is the longest side on the Triangle.

289-225=[tex]\sqrt{64\\}[/tex] = 8

b=8

b is the diameter of the Cylinder

Since we need the Radius squared for Cylinder we divide the Diameter in half. 8/2=4

4X4=16

Next we wil figure out the Volume,

[tex]\pi *4^{2} *15[/tex]=753.982236862

the answer is 753.98

Can you help me?

Answers

Answer:

= -5

Step-by-step explanation:

First you would use distributive property and multiply the 9 and 2 (18x) then 9 and 15 (135)
Now you have 18x+135=45 so you need to get X alone by using inverse operations and subtract 135-45 (90)
18x=90 now you divide 18 and 90 and your answer is x=5

(2) Then, a statement somewhat in detail of a course to be pursued seemed fitting and proper. (3) Now, at the expiration of four years, during which public declarations have been constantly called forth on every point and phase of the great contest which still absorbs the attention and engrosses the energies of the nation, little that is new could be presented. (4) The progress of our arms, upon which all else chiefly depends, is as well known to the public as to myself, and it is, I trust, reasonably satisfactory and encouraging to all. (5) With high hope for the future, no prediction in regard to it is ventured.(6) On the occasion corresponding to this, four years ago all thoughts were anxiously directed to an impending civil war. (7) All dreaded it, all sought to avert it. (8) While the inaugural address was being delivered from this place, devoted altogether to saving the Union without war, insurgent agents were in the city seeking to destroy it without war--seeking to dissolve the Union and divide effects by negotiation. (9) Both parties deprecated war, but one of them would make war rather than let the nation survive, and the other would accept war rather than let it perish, and the war came.(10) One-eighth of the whole population were colored slaves, not distributed generally over the Union, but localized in the southern part of it. (11) These slaves constituted a peculiar and powerful interest. (12) All knew that this interest was somehow the cause of the war. (13) To strengthen, perpetuate, and extend this interest was the object for which the insurgents would rend the Union even by war; while the Government claimed no right to do more than to restrict the territorial enlargement of it. (14) Neither party expected for the war the magnitude or the duration which it has already attained. (15) Neither anticipated that the cause of the conflict might cease with, or even before, the conflict itself should cease. (16) Each looked for an easier triumph, and a result less fundamental and astounding. (17) Both read the same Bible and pray to the same God, and each invokes His aid against the other.(18) It may seem strange that any men should dare to ask a just God's assistance in wringing their bread from the sweat of other men's faces, but let us judge not, that we be not judged. (19) The prayers of both could not be answered. (20) That of neither has been answered fully. (21) The Almighty has His own purposes. (22) "Woe unto the world because of offenses; for it must needs be that offenses come, but woe to that man by whom the offense cometh." (23) If we shall suppose that American slavery is one of those offenses which, in the providence of God, must needs come, but which, having continued through His appointed time, He now wills to remove, and that He gives to both North and South this terrible war as the woe due to those by whom the offense came, shall we discern therein any departure from those divine attributes which the believers in a living God always ascribe to Him? (24) Fondly do we hope, fervently do we pray, that this mighty scourge of war may speedily pass away. (25) Yet, if God wills that it continue until all the wealth piled by the bondsman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether."(26) With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.The primary purpose of the speech is to (3 points)A) outline reasons to blame the South for the warB) unify and heal a divided country after the warC) argue that slavery was the primary cause for the warD) establish the biblical support for the war From what did Oceans form?
