help me plz its algebra 1

Answer:

x= -7.27

Step-by-step explanation:

-81 = 5x + 3x + 3x - 1

combine all like terms

-81=11x-1

add 1 on both sides

-81=11x-1

+1 +1

-80=11x

divide by 11 on both sides to get x by itself

-80/11=11x/11

x=-7.27

Answer:

a/4-5/6=-1/2

or, 3a-10 /12 = -1/2. ( putting the factor)

or, 6a-20 =-12 (cross multiplication)

or, 6a= -12+20

or, a=8/6

or, a = 1.33 ( 4/3)

Answer:

the answer is (-3,-3)

Step-by-step explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:

a = 4

Step-by-step explanation:

[tex] \sin(theta) = \frac{opposite}{hypotenuse} [/tex]

[tex] \cos(theta) = \frac{adjacent}{hypotenuse} [/tex]

[tex] \tan(theta) = \frac{opposite}{adjacent} [/tex]

hypotenuse = a

opposite = 2√3

adjacent = b

theta = 60°

the best formula to use is the first formula cause we have all the values to substitute in it in order to find the value of a

[tex] \sin(60) = \frac{2 \sqrt{3} }{a} [/tex]

[tex] \frac{2 \sqrt{3} }{ \sin(60) } = a[/tex]

[tex]4 = a[/tex]

[tex]a = 4[/tex]

✓The number of hours of vaction time malcome earns in week= (120 hrs/52 weeks)

= 2.3 hours

Answer:

The time he spent at his friend's house is represented by the horizontal line, from .5 to 1.5 hours, which means he stayed at his friend's house for 1 hour.

Answer:

1 hour

Step-by-step explanation:

1) so lets look at the various aspects of this graph,

the first thing we see is a downhill spike from(0,4) to (0.5,2)

we can assume this segment is from riding to his friends house from school, as thats the first thing stated in this scenario. Next we notice a horizontal line(note: horizontal line means 0 slope, AKA no distance travelled) since Joey is not travelling at this time(hence the horizontal line) we can assume that thats when he was at his friends house. to find the amount of time he was at his friends house simply subtract the endpoints of the horizontal line

so: 1.5-0.5=1

he was at his friends house for 1 hour

Answer: h≈3.42in

Good luck!

Answer:

[tex]66.92\:\mathrm{m}[/tex]

Step-by-step explanation:

The area of a rectangle is given by [tex]l\cdot w[/tex] where [tex]l[/tex] is the length of the rectangle and [tex]w[/tex] is the width of the rectangle. Therefore, based on the information given, we can write the following equation to solve for the width:

[tex]15\cdot w=276.9,\\w=\frac{276.9}{15},\\w=18.46\:\mathrm{m}[/tex].

The perimeter of a rectangle is given by [tex]p=2w+2l[/tex]. Therefore, the perimeter of the rectangle is:

[tex]2(15)+2(18.46)=\fbox{$66.92\:\mathrm{m}$}[/tex].

Answer:

1,200 cubic cm

Step-by-step explanation:

First, you separate it into two prisms, which gives you two different volume formulas.

14*20*2 = 560

20*4*8 = 640

You then add the two volumes together, which equals 1,200

Answer: 10.49026 = 10.5

Step-by-step explanation:

The length of the side q of the triangle OPQ is 10.5 inches.

The law of Cosines, also known as Cosine Rule or Cosine Formula basically relates the length of the triangle to the cosines of one of its angles.

Given that, in a triangle OPQ, O = 4.4 inches, p = 9.6 inches and ∠Q=89°, we need to find the measurement of side q,

So, using cosine law for triangles,

q² = p²+o²-2poCos(89°)

= 4.4²+9.6²-2(4.4)(9.6)Cos(89°)

= 10.5

Hence, the length of the side q of the triangle OPQ is 10.5 inches.
