Can you help solve this

Answer:

x=1/5y-2

Step-by-step explanation:

Step 1: Flip the equation

5x+10=y

Step 2: Add -10 to both sides

5x+10+-10=y+-10

5x=y-10

Step 3: Divide both sides by 5.

5x/5 =y-10/5

x=1/5y-2

Answer:

A= 1/2 (b1 + b2)h

Step-by-step explanation:

A=area

b1 = base 1

b2 base 2

h = height

b1 = 24. b2= 12, h = 17

Substitute and solve!

Answer:

If the bisectors of two adjacent angles are perpendicular to each other, are the angles then supplementary angles?

Suppose two angles ABC and CBD are x and y.

x+y = 180 deg.

The bisector of angle ABC (BE) and the bisector of angle CBD (CF) will form angle EBF = (x/2)+(y/2) = 180/2 = 90 deg.

Conclusion: If the angle bisectors of two adjacent angles are perpendicular to eaxh other, the adjacent angles are supplementary angle

Adjacent angles are when the 2 angles have a common vertex and a common arm.

if the exterior sides of 2 adjacent angles are perpendicular, then the angles are complementary angles.

Then the sum of the 2 adjacent angles is a right angle - 90°.

When 2 angles add up to 90°, they are called a pair of complementary angles.

have a nice day

Answer:

$784

Step-by-step explanation:

Alright so we just need to find the percentage values of the discount and tax

What is 10%?:

x/800 = 10/100

8000 = 100x

x = 80

800 - 10%

800 - 80 = 720

What is 8%?:

x/800 = 8/100

6400 = 100x

x = 64

720 + 8%

720 - 64 = 784

Answer:

Solve systems of equations by graphing

A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

Example

[tex]\left \{ {{y=2x+2} \atop {y=x-1}} \right.[/tex]

Graph the equations in a coordinate plane

The two lines intersect in (-3, -4) which is the solution to this system of equations.

Answer:15

Step-by-step explanation:

Answer:

A = 20°

AC = 6.6

BC = 2.4

Step-by-step explanation:

Given:

B = 70°

C = right angle = 90°

AB = 7

Required:

A, AC, and BC

Solution:

✔️A = 180 - (90 + 70) (sum of triangle)

A = 20°

✔️Use trigonometric function to find AC:

Refernce angle = 70°

Opp = AC

Hypotenuse = 7

Apply SOH,

sin 70 = Opp/Hyp

sin 70 = AC/7

7 * sin 70 = AC

6.57784835 = AC

AC = 6.6 (nearest tenth)

✔️Use trigonometric function to find Bc:

Refernce angle = 70°

Adj = BC

Hypotenuse = 7

Apply CAH,

cos 70 = Adj/Hyp

cos 70 = BC/7

7 * cos 70 = BC

2.394141 = BC

BC = 2.4 (nearest tenth)

Answer:

x=10 , y=20

Step-by-step explanation:

2x–x=10

x=10

y=2x

y=2(10)

y=20

Answer:

The number of terms in the sequence is 9

Step-by-step explanation:

We want to get the number of terms

Mathematically, we have the formula for the sum of terms in an arithmetic sequence as

[tex]sn = \frac{n}{2} (a + 1)[/tex]

a represents the first terms, and i represent the last term

[tex]423 = \frac{n}{2} (15 + 79) \\ \\ 423 \times 2 = 94(n) \\ \\ 94n = 846 \\ \\ n = \frac{846}{94} \\ \\ n = 9[/tex]

Answer:

C=[tex]14\pi[/tex] or ≈43.96cm

Step-by-step explanation:

Start by figuring out the Area of the circle to get the radius (r)

Area (A)=153.86 cm

A=[tex]\pi r[/tex]²

153.86=[tex]\pi[/tex]r²

153.86÷[tex]\pi[/tex]=r²

49=r²

√49= r

r= 7cm

Next insert r=7cm into the Circumference equation of a circle

C=2[tex]\pi[/tex]r

C= 2×[tex]\pi[/tex]×7

C=14[tex]\pi[/tex] or C=43.96cm

[tex]x\geq -9[/tex]

Step-by-step explanation:

Answer:

x ≥ - 9

Step-by-step explanation:

Given

18 ≥ - 2x

Divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity,

- 9 ≤ x , that is

x ≥ - 9

Answer:

obtuse triangle

Step-by-step explanation:

it is obtuse because it needs to have all 3 sides to be acute to be an acute angle and it doesn't have any 90° angles so it has to be obtuse. Also because to be an obtuse it has to have 2 acute angles and 1 obtuse angle. Hope this helps!!

Answer:

it's B, C, and D

Step-by-step explanation:

A. w ⋅ 462 = 16 1/2

not A

w * a ≠ l

B. 16 1/2 ⋅ w = 462

is B

l * w = a

C. 462 ÷ 16 1/2 = w

is C

a / l = w

D. 462 ÷ w = 16 1/2

is D

a / w = l

E. 16 1/2 ⋅ 462 = w

not E

l * a ≠ w
