simplify: ,3(x-2) + 2(2x+5) =32, a+2a+7a
Answer:
x = 4, 10a
Step-by-step explanation:
3(x-2) + 2(2x+5) = 32
3x - 6 + 4x + 10 = 32
3x + 4x + 10 - 6 = 32
7x + 4 = 32
7x = 32 - 4
7x = 28
Divide both side by 7
x = 4
a + 2a + 7a
They are common because the have the same variables.
'a' is with a coefficient of 1
You add the coefficient and attach the variable to it
Therefore,
a + 2a + 7a = 10a

52cm^2
Step-by-step explanation:
I did the splitting in my head and that's pretty hard to explain like this so, just BTW if your confused on where I got my lengths from.
(7*6) + (5*2)
(42) + (10)
52
I separated them into an almost square and a rectangle, then I found the area of each rectangle and then added them together.
Hopefully this was useful and you didn't have any issues with this!

Answer:
a) KJL = 76⁰
b) LKM = 76/2 = 38⁰
Answer:
∠KJL = 76°
∠LKM = 38°
Step-by-step explanation:
since arc KL = 76°, ∠KJL also = 76° because central angles are congruent to their arcs.
∠LKM = 1/2 arc KL = 1/2(76°) = 38°

In the figure, all lines intersect at point W.
What is the value of n?
Please help quick
Answer:
n = 15
Step-by-step explanation:
A straight line equals 180 degrees
Angle SWT is congruent to angle XWV meaning:
SWT (55 degrees) = XWV (55 degrees)
Set up an equation:
3n + 80 + 55 = 180
Combine like terms
3n + 135 = 180
Subtract both sides by 135 to isolate variable n
3n = 45
Divide both sides by 3 to isolate variable n
n = 15

The system of equations n=2p+3 and n=5p is graphed.what is the solution to the system of equations
Answer:
n=7 and p=2
Step-by-step explanation:
Graph is not given,
we have n=2p+3 and n=5+p
that's 2p+3=5+p
P=5 - 3
P=2
so the solution is n=7 and p=2

Order the side from greatest to least.
Η.
28°
118°
K
J
side [Select ]
Answer:
HJ>KJ>HK
Step-by-step explanation:
Side opposite to the largest angle is the largest.
Side opposite to smallest angle is the smallest.
ang K = 118° ang J = 28°
ang K + ang J + ang H = 180° (Sum of all the angles in the triangle is 180°)
118°+28°+angH=180° (Putting the values of ang K & ang J)
146°+angH=180°
ang H=180°-146°
ang H=34°
128°>34°>28°
ang K>ang H>ang J
Here, ang K is the largest, so the side opposite to it i.e. HJ will be the largest side.
Smaller than ang K and bigger than ang J is ang H, so the side opposite to it i.e. KJ will be smaller than HJ but bigger than HK.
Ang J is the smallest angle, so the side opposite to it i.e. HK will be the smallest.
HJ>KJ>HK.

How do you work out the circumference of this circle step by step?
Answer:
It says c = πd
The circumference is π X d (diameter)
on the image the diameter shown on the circle is 14cm
π = 3.14
3.14 X 14cm = 43.96cm
List the pairs of congruent angles and the extended proportion that relates the corresponding sides for the similar triangles. Plz this is due today!!!! I tried 3 times already!!!! More in pic.
9514 1404 393
Answer:
angle pairs: correctEF/HI = EG/HJ = FG/IJStep-by-step explanation:
As with the angle pairs, use the corresponding vertices to name corresponding segments.
As is done here, I find it convenient to list the vertices vertically in the order shown in the similarity statement.
∠E ≅ ∠H∠F ≅ ∠I∠G ≅ ∠JThis can make it easier to identify the corresponding vertices used for naming segments.
__
Moving on the the extended proportion, ...
The denominator HI uses the first two vertices, with E corresponding to H and F corresponding to I. The appropriate ratio is ...
EF/HI
The denominator HJ uses the 1st and 3rd vertices, with E (still) corresponding to H and J corresponding to G. The appropriate ratio is ...
EG/HJ
Similar thinking is used to identify the last ratio:
FG/IJ
Then the extended proportion is ...
EF/HI = EG/HJ = FG/IJ
Which shapes have parallel sides? Choose ALL the correct answers
Answer: The shapes that have parallel sides would be the blue diamond (bottom right) and the green trapezoid (top right).
The shapes that have the parallel sides should be blue diamond (bottom right) and the green trapezoid (top right).
What are parallel sides?The parallel sides are considered as the two sides or line that should be parallel to one other also it contain the same kind of distance also it never intersected or even touched to one another.
hence, The shapes that have the parallel sides should be blue diamond (bottom right) and the green trapezoid (top right).

Answer:
u = 21
Step-by-step explanation:
WX = XY because (VW = VY)
WX = u + 42
XY = 3u
u + 42 = 3u
42 = 3u - u
42 = 2u
u = 42 / 2
u = 21
Answer:
u = 21
Step-by-step explanation:
Consider triangle XWV and triange XYV
XV = XV (common)
Angle XVW = Angle XVY (given)
VW = VY (given)
∴triangle XWV ≅ triange XYV (SAS)
∴ XW = XY (corr. sides, ≅ triangles)
u + 42 = 3u
u = 21
Suppose you have a bag of marbles. You know that there are 10 marbles in the bag,
but you do not know what colors they are. You select a marble 40 times, each time
recording its color before putting it back. In 8 out of 40 trials you select a purple
marble.
Based on the data, how many purple marbles do you estimate are in the bag? Explain
your prediction
Answer:
8 out of 40 trials- 8/40
simplify that and it becomes 1/5
1/5 of 10 is 2
so, I'd estimate there are 2 purple marbles.
25 49/80 as a decimal
Answer:
25.6125
Step-by-step explanation:
since 25 is a whole number, it'd be 25.ˣˣˣˣ
now all you have to do it divide the fraction so 49 ÷ 80 = 0.6125
last step is to add ⇒ 25 + 0.6125 = 25.6125
