Answer:
41
Step-by-step explanation:
8 x 7 - 5 ([tex]3^{2}[/tex] - 6)
= 8 x 7 - 5 ( 9 - 6 )
= 8 x 7 - 5 x 3
= 56 - 15
= 41
Answer:
41
Step-by-step explanation:
Use PEMDAS.
3^2 = 9
9 - 6 = 3
3 × 5 = 15
8 × 7 = 56
56 - 15 = 41

6x + 3y = -12
-6x - 2y = 4
Answer:
x=2
y=-8
Step-by-step explanation:
6x+3y=-12
-6x-2y=4
3y=-12-6x
y=(-12-6x)/3
y=-4-2x
substitute y
-6x-2(-4-2x)=4
-6x+8+4x=4
-2x=-4
x=2
6(2)+3y=-12
12+3y=-12
3y=-24
y=-8
check:
6(2)+3(-8)=-12
12-24=-12
-6(2)-2(-8)=4
-12=16=4

Solve the system using elimanation: 3x + 5y = -2 and -x + 2y = 8
Answer:
Step-by-step explanation:
3x+5y+3(-x+2y)=-2+3(8)
3x+5y-3x+6y=-2+24
11y=22
y=2, using this y in -x+2y=8 gives you
-x+2(2)=8
-x+4=8
-x=4
x=-4
So the solution is the point (x, y)=(-4, 2)

what is the value of c?
Answer:
The value of C is 3
Step-by-step explanation:
all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.

Answer:
3a+5
Step-by-step explanation:
add-4a and 7a
3a+14-9
subtract 9 from 14
3a+5
Answer:
[tex] \sf \: 3a + 5[/tex]
Step-by-step explanation:
Given expression,
→ -4a + 14 + 7a - 9
Let's simplify the expression,
→ -4a + 14 + 7a - 9
→ (-4a + 7a) + (14 - 9)
→ (3a) + (5)
→ 3a + 5
Hence, the answer is 3a + 5.

What is the area of "triangle " XYZ to the nearest tenth of a square inch? Use special right triangles to help find the height. Show your work.
Answer:
That is a 30 60 90 triangle.
In such a triangle the "middle" size = short side * sq root (3)
height = 5 * sq root (3) = 8.6602540378
Area = (1/2) * 5 * 8.6602540378
Area = 2.5 * 8.6602540378
Area = 21.6506350946 square centimeters

Answer:
A=24√3
Put In Decimal Form:41.5692193817^3
Step-by-step explanation:
4 Inches on short side, this means that the long side is 8 inches because the short side is always 1/2 the length of the long side, The medium side length is 4√3. So you need to take the short side and medium side and multiply them by 1/2, look below for how to do it.
A=1/2(4)(4√3)
2(12√3)
24√3

9514 1404 393
Answer:
15.08 m
Step-by-step explanation:
You can take the appropriate fraction of the whole circumference, or you can use the arc-length formula. You get the same answer either way.
Angle XZW is 180° -108° = 72°
The circumference is C=πd, so the arc of interest is ...
XW = C(72°/360°) = πd/5 =π(24 m)/5 = 4.8π m
XW ≈ 15.08 m
_____
If you use π = 3.14, then your answer will be 15.07 m.
