Solve the following two equations. Show all of your
steps in the line paper provided. Be ready to share your
work!
Equation #1: 3x + 11 = 11
Equation #2: 3(x – 3) = 45

Answers

Equation 2:
3(18 - 3) = 45
step 1 do 18-3
now you have
3(15) = 45
and it’s just three, times fifteen.
3 • 15 = 45

Equation 1:
3x + 11 = 11
3x = 11 - 11
3x = 0 (divide both sides by 3 to get x)
3x/3 = 0/3
x = 0

Determine the intercepts of the line.
y=10x-32y=10x−32

I need to determine the y intercept and the x intercept

Answers

Answer:

x=16/5

y=1

Step-by-step explanation:

To find the x, substitute in 0 for y and solve for x.

0=10x−32

Solve the equation.

Rewrite the equation as 10x−32=0

Add 32 to both sides of the equation.

10x=32

Divide each term by 1010 and simplify.

10x/10=32/10

x=32/10=16/5

Answer:

60 cm²

Step-by-step explanation:

The shaded area is calculated as

area of trapezium - area of white triangle

The area (A) of trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h( b₁ + b₂)

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 12, b₁ = 14 and b₂ = 10 , then

A = [tex]\frac{1}{2}[/tex] × 12 × (14 + 10) = 6 × 24 = 144 cm²

The area (A ) of the white triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the height )

Here b = 14 and h = 12

A = [tex]\frac{1}{2}[/tex] × 14 × 12 = 7 × 12 = 84 cm²

shaded area = 144 - 84 = 60 cm²

60 cm2 thats the anwser i got.

Answers

Answer:

x=5

Step-by-step explanation:

The sum of the measures of angle M and angle R is 90°

Given;

•Angle M is (5x+10)°

•Angle R is 55°

The value of x therefore is;

Measure of Angle M + Measure of Angle R = 90°

(5x+10°)+55°=90°(Remove bracket)

5x+10°+55°=90°

5x+65°=90°

5x=90°-65°

5x=25(Divide both sides by 5)

x=5

Therefore the value of x=5

In a song competition, a participant has to score a total of at least 20 points in the first four rounds combined to move on to the fifth and final round. Curtis scored 2 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Curtis scored in each of the second, third, and fourth rounds if he earned a place in the finals?
