Answer:
64
Step-by-step explanation:
Okay, here it goes:
Where there is a g you insert -2 and where there is an h you insert 5
(2(-2)+9(5)-5)-(6(-2)-4(5)+2)
If two numbers are side-by-side with no other sign between them, you multiply
(-4+45-5)-(6(-2)-4(5)+2)
(-4+45-5)-(-12-20+4)
There is a subtraction sign between these equations. That means you must distribute the negative sign to the equation on the right.
Remember:
Negative × Negative = PositiveNegative × Positive = NegativePositive × Positive = Positive-4+45-5+12+20-4
Now just add them together. I recommend going left to right.
-4+45=41
41-5=36
36+12=48
48+20=68
68-4=64

Answer:
Step-by-step explanation:
x+5+x+7x-5=180 degree (being the interior angles of a triangle)
9x=180
x=180/9
x=20 degree
Answer:
x° = 20°
Step-by-step explanation:
Sum of angles of triangles = 180°
Therefore,
(x + 5) + (7x - 5) + x = 180
x + 5 + 7x - 5 + x = 180
9x = 180
x = 20
∠M = (x + 5) = 20 + 5 = 25°
∠L = (7x - 5) = 140 - 5 = 135°
∠N = x = 20°

Answer:
Angle = 33
Step-by-step explanation:
Angles should add up to 180 and the angles shown are 90 and 57 and then add those to get 147 then subtract 147 by 180 to get 33 for the angle. Hope this helps!

Answer:
x=24
Step-by-step explanation:
Because the triangle is a 30-60-90 triangle, you can find side x, the hypotenuse, by doubling the short side 12. Therefore, x=2(12)=24.

x + 3 > 70
How do I solve this step by step?
Answer:
x > 67
Step-by-step explanation:
x+3 >70
subtract from each side
x+3-3 > 70 -3
x > 67
Algebra
To solve this, simplify the algebra inequality.
Subtract three from both sides.
x>67
Meaning, x is bigger than 67.
Manuel, a plumber, has several pieces of pipe on his truck. He has a piece 6 feet long. A piece 7 feet long, one 9 feet long, and a piece 13 feet long. Find the total length of pipe in feet. If he uses 5 feet of pipe on a job, how many feet of pipe are left?

Jack is 5 years older than Mary. In four years the sum of their age is 33 years old. What are their ages?
Answer:
mary=10 jack=15
Step-by-step explanation:
After 4 years Mary (x+4), Jack's age (x+5) + 4.
sum of the ages after 4 years :(x+4) + (x+5) +4=33
Simplifying the equation:
2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age
10 + 5 = 15 which is Jack's age.

Put Y=x^2+10x+18 in vertex form
Answer:(-5,-7)
Step-by-step explanation:
Rewrite in Vertex form and use this form to find the vertex (h,k)
Answer:
y = (x + 5)² - 7
Step-by-step explanation:
Given
y = x² + 10x + 18
To obtain vertex form use the method of completing the square
add/ subtract ( half the coefficient of the x- term )² to x² + 10x
y = x² + 2(5)x + 25 - 25 + 18
= (x + 5)² - 7 ← in vertex form
Write an equation of the line that passes
through (0, – 5) and is perpendicular to
the line y= - 4/5x
Answer:
y=5/4x-5
Step-by-step explanation:
Hi there!
The equation of the line is typically written as y=mx+b, where m is the slope and b is the y intercept
Perpendicular lines have slopes that are negative and reciprocal. If they are multiplied together, the result is -1
So let's find the slope of the perpendicular line with this formula:
-4/5m=-1
multiply both sides by -5/4 (we need to isolate m onto one side, and -4/5*-5/4=1)
m=5/4
So the slope of the new line is 5/4
Here's the equation so far:
y=5/4x+b
now we need to find b
Because the equation of the line passes through (0,-5), we can use it to solve for b
substitute 0 as x and -5 as y
-5=5/4(0)+b
-5=0+b
-5=b
Therefore the equation of the line is:
y=5/4x-5
Hope this helps!

I need help with this question
Answer:
O = 41 degrees
Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
the graphic shows that this triangle has 2 equal sides. that means that both angles at O and at M are equal.
so, we know all three angles and can calculate
7y + 2×(4y - 15) = 180
7y + 8y - 30 = 180
15y = 210
y = 14
so, the angle at O is
O = 4×14 -15 = 56 - 15 = 41 degrees

Answer with step-by-step explanation:
I'll use the list of referents you had on your other question and I believe this is a reference to that list.
Part A:
Use the reference of an adult stride (about 1 yard) to estimate the dimensions and length of the lawn edging. The dimensions can be used to find the area, in square yards, that is required to fill both sides of the flower beds.
Part B:
Similarly, you can use an adult stride of about 1 yard as a reference to measure to dimensions of the paved area and the dimensions of the brick. Using these dimensions, you can find area of the paved walkway and the area (surface area of top only) in square yards. Use these areas to find the approximate number of bricks needed to fill the walkway.

Solve for q. Write your answer as “q=___”
Answer:
7q-46= 3q +6
7q-3q = 6+ 46
4q= 52
4q/4= 52/4
q= 13
Answer:
Hello! q = 22
Step-by-step explanation:
This is a supplementary angle meaning it will add up to 180 degrees so...
22 × 7 = 154 154 - 46 = 108
3 × 22 = 66 66 + 6 = 72
108 + 72 = 180 therefore q = 22 hope that helps!
