solve 15=2y - 5 (for homework)
y=10
2×10=20-5=15
.......
Answer:
y=10
Step-by-step explanation:
15 = 2y - 5
add 5 to both sides
15 + 5 = 2y - 5 + 5
add the numbers
20 = 5y
divide
y = 10
Find the area of this triangle. PLS HELPP!!
Answer: 152ft squared
Step-by-step explanation:
When solving the area of a triangle you multiply by 1/2 so your equation would be 1/2*16*19 = 152ft squared. (Do not forget your units in other problems!!!)

3rd option: The number of protons and neutrons
Step-by-step explanation:
Protons are positively charged
Neutrons are negatively charged
You can easily remember this by the P and N
For an object to be "neutral", the protons and neutrons have to be equal. If they are not equal it will be positively charged of negatively charged.

2(2x²+8x-5x-20) split the three into a difference
2(2x(x+4)-5x-20) factor the 2 out of first pair of parenthesis
2(2x(x+4)-5(x+4)) factor the 5 out of second pair of parenthesis
2(x+4)(2x-5) factor

Need help with this question
Answer:
x = 2.3
Step-by-step explanation:
Since we know all three sides, what we do here is multiply side a & b's lengths together and divide by the hypotenuse. (a + b)/c
(2.5 * 6)/6.5
Step 1: Multiply 2.5 by 6 to get 15.
15/6.5
Step 2: Convert 6.5 into a whole number by multiplying it by 10. Make sure to do that to the 15 as well.
150/65
Step 3: 150/65 simplifies to 30/13 (GCF: 5).
30/13
Step 4: 30/13 becomes 2 4/13.
2 4/13
Step 5: 2 4/13 rounds to 2.3
2.3 is the value of x.
The lengths, in cm, of the sides of a triangle are 3x – 5, 2x – 1 and x + 1 (a) Write down an expression, in terms of x, for the perimeter of the triangle.
Answer: [tex]6x-5[/tex]
Step-by-step explanation:
Given
The side lengths of a triangle are [tex]3x-5, 2x-1,\text{and}\ x+1[/tex]
Perimeter(P) is the sum of the side length of the triangle i.e.
[tex]\Rightarrow P=3x-5+2x-1+x+1\\\Rightarrow P=6x-5[/tex]
Therefore, the perimeter of the triangle is [tex]6x-5[/tex]

14m to 140cm witch is more
Answer:
14 m is more
Step-by-step explanation:
14 meters = 1400 cm
14 x 100=1400
Answer:
14 m is more
Step-by-step explanation:
1 m = 100 cm
14 m
= 14 x 100
= 1400 cm
1400 cm > 140 cm
14 m > 140 cm

Find the length of each arc. Use the exact answer
Answer:
Option D = 16π/3 ft
Step-by-step explanation:
Arc length formula is written Mathematically as:
Arc length = 2πr × θ /360
r = 4 ft
θ = Central angle in degrees = 240°
2 × π × 4 × 240/360
8π × 240/360
8π × 20/30
16π/3 ft
So, the arc length is 16π/3 ft

a 3 inch radius circle is drawn inside a 7 in radius Circle if you throw a dart at the circles what is the probability you land inside the smaller circles
Answer:0.82
Step-by-step explanation:
The first step is to determine the areas of the inner and the bigger circles.
The formula for determining the area of a circle is expressed as
Area = πr²
Where
r represents the radius of the circle.
π is a constant whose value is 3.14
Considering the inner circle,
diameter = 148.4 cm
Radius = 3 inches
Area = 3.14 × 3² = 28.26 inches²
Considering the bigger circle,
Radius = 7 inches
Area = 3.14 × 7² = 153.86 inches²
The area between the bigger and inner circles is
153.86 - 28.26 = 125.6 inches²
Probability = number of favourable outcome/number of total outcome.
the probability you land inside the bigger circle but outside smaller circle is
125.6/153.86 = 0.82
y = x2 + 12x + 30
8x − y

1. Slope of HE =??
2. Slope of GF =??
3. Slope of HG =??
4. Slope of EF =??
Answer:
Use coordinates of the vertices and the slope formula.
H(-3, 0), E(1, 4), F(3, 2), G(-1, -2)1. Slope of HE:
m = (4 - 0)/(1 + 3) = 12. Slope of GF:
m = (-2 - 2)/(-1 - 3) = 13. Slope of HG:
m = (-2 - 0)/(-1 + 3) = -14. Slope of EF:
