-81 = 5x + 3x + 3x - 1
solve the multi step equation
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

The area of a rectangle is 276.9 m². If the length is 15 m, what is the perimeter of the
rectangle?
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].

Use the diagram to prove that ∆CAS≅TAS.
The two-column proof that shows that ΔCAS ≅ ΔTAS by HL Congruence Theorem is shown in the table attached below.
What is the HL Congruence Theorem?The HL Congruence Theorem is used to prove two right triangles congruent if both triangles have a pair of congruent hypotenuse and a pair of congruent legs.Thus, ΔCAS and ΔTAS both have a pair of congruent legs and a pair of congruent hypotenuse. Therefore, the two-column proof that shows that ΔCAS ≅ ΔTAS by HL Congruence Theorem is shown in the table attached below.

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
In ΔOPQ, o = 4.4 inches, p = 9.6 inches and ∠Q=89°. Find the length of q, to the nearest 10th of an inch.
Answer: 10.49026 = 10.5
Step-by-step explanation:
The length of the side q of the triangle OPQ is 10.5 inches.
What is cosine law?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.
