Area of figure = area of trapezoid + area of rectangle
A(rectangle) = 18 x 5 = 90 cm2
A(trapezoid) = (10+18) x (13-5) : 2 = 112 cm2
A(figure) = 112 + 90 = 202 cm2

The second one: [tex]8x^{2}y+7x^{2}-5y^{2}+3x-2+2x^{2}y-x^{2}-2y^{2}-3x-4[/tex]
Step-by-step explanation:
You have to combine the like terms (any numbers with the same variables and exponents)
[tex]8x^{2}y+2x^{2}y=10x^{2}y, 7x^{2}-x^{2}=6x^{2}, -5y^{2}-2y^{2}=-7y^{2}, 3x-3x=0, -2-4=-6[/tex]
If you put all of the answers together you get [tex]10x^{2}y+6x^{2}-7y^{2}-6[/tex]

Since you have the “-th” in your problem we know it’ll have a decimal
Now let’s start solving!
8 would be in your ONES place
.
7 would be in your TENTHS place
4 would be in your HUNDREDTHS place
Your answer SHOULD look like this: 8.74 ☑️

1.) Diego paid $47 for 3 tickets to a concert. Andre paid $141 for 9 tickets to a concert.
Did they pay at the same rate (what was the value they paid for 1 ticket)? How do you
know?
Answers
The value they paid for one ticket is 15.67$
How do you know:
Andre paid for 3 times more tickets than Diego. 47 x 3 is 141, so they are at the same rate.
47 / 3 is 15.667, which rounds up to 15.67$ in money terms.

Using the figure below, find the measure of z ( just enter in the number for your answer don’t worry about the degree symbol or saying “ degrees” after the number
Answers
Answer:
z = 29°
Step-by-step explanation:
We know that the 3 angles in a triangle always add up to 180°. So for triangle ABC, angle A = 59° (given), and angle B = 43° + 49° = 92° (given).
angle A + angle B + angle C = 180°
59° + 92° + z = 180°
151° + z = 180°
Subtract 151° from both sides of the equation
z = 180° -151°
z = 29°

Answers
Answer:
1. x = 5
Remember that all angles add up to 180, and because you know that one of the angles = 90, you can add the other two angles like so.
6x + 15 + 10x - 5 = 90

Write the equation for a parabola whose vertex is (-6,-1) and passes through (-12,17).
Answers
Answer:
[tex]y=\frac{1}{2}(x+6)^2-1[/tex]
Step-by-step explanation:
Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that graphically represents the function, and a is a coefficient different from zero.
The vertex of the required equation is located at (-6,-1)
The parabola passes through (-12,17)
Substituting the coordinates of the vertex, the equation of the function is:
[tex]y=a(x+6)^2-1[/tex]
The value of a will be determined by using the given point:
[tex]17=a(-12+6)^2-1[/tex]
Operating:
[tex]17=a(36)-1[/tex]
[tex]36a=18\Rightarrow a=18/36=1/2[/tex]
Solving:
[tex]a=1/2[/tex]
The equation of the parabola is:
[tex]\boxed{y=\frac{1}{2}(x+6)^2-1}[/tex]

Nikki used the calculations shown to determine whether a carton of 12 eggs or a carton of 18 eggs was the better buy. A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39. Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg The 12-egg carton has the lower unit cost, so it is the better buy. What was her first error?
Answers
Given :
A carton of 12 eggs or a carton of 18 eggs was the better buy. A carton of 12 eggs cost $2.39, and a carton of 18 eggs cost $3.39. Unit price of the 12-egg carton = ($2.39)(12 eggs) = $28.68 per egg Unit price of the 18-egg carton = ($3.39)(18 eggs) = $61.02 per egg The 12-egg carton has the lower unit cost, so it is the better buy.
To Find :
What was her first error.
Solution :
Her first error is to find Unit price of egg in each carton.
To find, unit price we should divide total amount by number of units :
Unit price for carton of 12 eggs, $ (2.39)/12 = $0.199 .
Hence, this is the required solution.
Answer:
She is right, however her explanation is wrong.
In order to find the unit price, you need to divide the amount by the cost.
You will then see that 12 divided by 2.39 < 18 divided by 3.39.
The smaller unit price is obviously the better buy.

Q. 3: If x/7 = 21, then find x. Learning algebra helps to develop your critical thinking skills. That includes problem solving, logic, patterns, and reasoning. You need to know algebra for many professions, especially those in science and math.
Algebra is a system of manipulating numbers and operations to try to solve problems. When you learn algebra, you will learn the rules to follow for solving problems. But to help make that easier, you need to have a strong understanding of basic math facts. ... Being able to work with two-digit numbers is even more helpful. The Basic Laws of Algebra are the associative, commutative and distributive laws. They help explain the relationship between number operations and lend towards simplifying equations or solving them. Algebraic expressions include at least one variable and at least one operation (addition, subtraction, multiplication, division). For example, 2(x + 8y) is an algebraic expression. Algebra is thinking logically about numbers rather than computing with numbers. ... Paradoxically, or so it may seem, however, those better students may find it harder to learn algebra. Because to do algebra, for all but the most basic examples, you have to stop thinking arithmetically and learn to think algebraically. Algebra is an important life skill worth understanding well. It moves us beyond basic math and prepares us for statistics and calculus. It is useful for many jobs some of which a student may enter as a second career. Algebra is useful around the house and in analyzing information in the news.

Answers
Answer:
I think the candy cost 51 dollars
Jellybeans: 36$
Gummy worms: 15$
36 + 15 = 51
Step-by-step explanation:
Since jeremiah bought 1 pound for 9 dollar you can minus 9 from the equation which is 51 and since each pound of jelly beans were 9 dollars 9 x 4 = 36 and 51 - 36 is 15 so the cost of the gummy worms are 15 so
either 51 or 36 and 15
