Answers
Answer:
24 inches squared
Step-by-step explanation:
That is a triangle, and the area of a triangle is 1/2(b)(h), which is one half times the base times the height. Let's identify those things.
1/2: the area of a rectangle can be calculated base times the height, and a triangle is half of that rectangle, hence the 1/2
(b) or base: base is usually identified as the horizontal line in the triangle, which is 6 inches in this case.
(h) or height: height is usually the vertical line, and in this case, the vertical line is 8 inches.
Now time for the math:
1/2(6)(8) = 24 inches squared

Pls help ASAP
Answers
Answer:
n-6h+9
first you subtract the ns from each other because those are the only like terms
So first you get all the like terms together from calculating the addition sequence here from their coefficients
So
(3-2-6)x+9
Now you calculate the difference in the parenthesis
-5x+9 is your answer and you leave it like that because you can’t really do anything else just leave it how it is
The cost for 5 adults and 3 children to attend a show is $210. ( /5)
For 2 adults and 5 children the cost is $160.
Form a pair of simultaneous linear equations and solve them to find the cost of:
i. an adult ticket
ii. a child ticket
Answers
Answer: i. Cost of adult ticket = $ 30
ii. Cost of child ticket = $20
Step-by-step explanation:
Define variables:
Let x= cost of 1 adult tickets , y= cost of 1 child tickets.
Form linear equations:
5x+3y = 210 (i)
2x+5y= 160 (ii)
Multiply (i) by 2 and (ii) by 5
10x +6y = 420 (iii)
10x+25y = 800 (iv)
Eliminate (iii) from (iv)
19y = 380
⇒ y= 20
Put this in (i)
[tex]5x+3(20)=210\Rightarrow\ 5x+60 = 210\\\\\Rightarrow\ 5x=150\\\\\Rightarrow\ x=30[/tex]
Hence, Cost of adult ticket = $ 30 and Cost of child ticket = $20

Answers
Answer:
x = 7
Step-by-step explanation:
BD is an angle bisector of ∠ABC,
Therefore, by angle bisector theorem,
∠ABD ≅ ∠CBD
m∠ABD = m∠CBD
(2x + y) = (14 + y)
2x = 14
x = 7
what is m∠2 if m∠6 = 120°?
Answers
Answer:
I love ur pfp
Step-by-step explanation:
ANSWER: m∠2 = 120°, m∠3 = 60°; Sample answer: ∠1 and ∠2 are alternate exterior angles, so they have the same measure. ∠2 and ∠3 are supplementary. So, m∠3 = 180° – 120° or 60°.

C(2,8); y = - 4x + 5
y =
(Type your answer in slope-intercept form.)
Answers
Answer:
y = -4x + 16
Step-by-step explanation:
The slope of the given line is -4
when two lines are parallel, their slopes are equal
That means the slope of the second line is -4 too
Thus, we have to use the point-slope form to write the equation
That will be
y-y1 = m(x-x1)
y-8 = -4(x-2)
y -8 = -4x + 8
y = -4x + 8+8
y = -4x + 16
Write the equation for the graph below:

QUICK PLZ!!! Use the number line below, where RS = 6y + 3, ST = 4y + 7, and RT = 60.
Answers
Step-by-step explanation:
[Diagram in image attached]
RS + ST = RT
(6y +3) + (4y + 7) = 60
6y + 3 + 4y + 7 = 60
10y + 10 = 60
10y = 60 - 10
10y = 50
y = 50/10
y = 5
RS = 6y +3 = 6(5) + 3 = 30 + 3 = 33
ST = 4y +7 = 4(5) + 7 = 20 + 7 = 27
RT = 60
{RS + ST = RT
33 + 27 = 60}

m=2 and n=16 , p = {1-6 =-5} then;
1. m+10 = 2+10 = 12
2. n-4 = 16-4 = 12
3. m / n = 2/16 = 1/8
4. 6m - 1 = 6*2 - 1 = 12 -1 = 11
5. 3p =3* -5 = -15
6.12 p = 12* -5 = -60
