Answer:
a number (x) plus (+) -3 (-3) is (=) 8 (8).
Step-by-step explanation:
x+(-3)=8
x=11
Answer:
A number: since we don't know what the exact number is we can represent that number with a variable. Let's use x...
x + (-3) = 8
You can also write this as...
x - 3 = 8
They both mean the same thing :)
When you solve...
x - 3 = 8
add 3 on both sides...
x = 11
Your answers are...
x + (-3) = 8
x = 11
Hope this helps :)
Is there enough information to determine if the following triangles are similar? Justify your response.
Answer:
No.
Step-by-step explanation:
Triangle DFE justifies itself with the SAS (side-angle-side) postulate, while Triangle ABC simply shows that ∡B & A are similar. They are not justified by the same standard, and so there is no way to tell if these triangles are similar.

Answer:
make a graphical representation for our case do we have infinite lines pass through a point M?
Step-by-step explanation:
If the graphs of the equations do not intersect (for example, if they are parallel), then there are no solutions that are true for both equations. If the graphs of the equations are the same, then there are an infinite number of solutions that are true for both equations.
3. Mateus recebe a visita do seu avô Pedro a cada 15 dias. João, o tio dele, o visita a cada 100
e, devido a escalas de trabalho, a cada 12 dias Mateus vai à praia com seus pais. Um belo dia Mans
recebeu a visita do seu avô, do seu tio e foi à praia com seus pais (com o avô e o tio que o visitavam nese
dia). Quantos dias depois este acontecimento se repetirà?
Answer:
Este acontecimento se repetirá 300 dias depois.
Step-by-step explanation:
Quando os eventos se repetirão no mesmo dia?
Cada evento tem uma frequência.
Eles ocorrem simultaneamente a cada x dias, e x é dado pelo MMC(Mínimo Múltiplico Comum) entre as frequência.
Neste problema:
A cada 15 dias o avô visita.
A cada 100 dias o tio visita.
A cada 12 dias vai à praia.
Quantos dias depois este acontecimento se repetirá?
Os três no mesmo dia vão se repetir após x dias, em que x é dado pelo MMC de 15, 100 e 12
MMC de 15, 100 e 12
Fatorando simultâneamente estes valores:
15 - 100 - 12|2
15 - 50 - 6|2
15 - 25 - 3|3
5 - 25 - 1|5
1 - 5 - 1|5
1 - 1 - 1
Então:
mmc(15,100,12) = 2*2*3*5*5 = 300
Este acontecimento se repetirá 300 dias depois.

Which expression is equivalent to d-6d-3dd−6d−3d?
From the given expression in our example we have say
y = d-6d-3dd−6d−3d,
the equivalent expression would be y = -14-3dd
We can see two different terms
the "d" terms and the "dd" terms
Let us collect like terms
we have
y= d-6d-6d-3d-3dd
y = d-12d-3d-3dd
y= d-15d-3dd
y = -14-3dd
Hence the equivalent expression is y = -14-3dd

Answer:
Step-by-step explanation:
so we need two even intergeters that add to 70 when we multiply the bigger by 2 and add the smaller to that soooo
70= 2*y + x
but we can express x in terms of y b/c it's a consecutive even integer soo
(b/c x+2 = y, then x = y -2)
70= 2*y + (y-2)
70 = 2y + y - 2
72 = 3y
24 = y :) nice the bigger is 24 so the smaller is 22
70 = 2*24 + 22
70 = 48 + 22
70 = 70 nice !
bigger = 24
smaller = 22

Answer:
bigger = 24

How do I solve this problem. 7a+2=3a+1
Answer:
a= - 1/4
Step-by-step explanation:
Answer:
- 1/4
Step-by-step explanation:
7a + 2 = 3a + 1
subtract the 1 from both sides
7a + 1 = 3a
subtract 7a from both sides
1 = - 4a
divide by - 4
A = - 1/4

octagon
nonagon
decagon
heptagon
9514 1404 393
Answer:
nonagon
Step-by-step explanation:
The adjacent exterior angle is 180° -140° = 40°. There are 360°/40° = 9 of those angles around the regular polygon, so it is 9-sided.
The polygon is a nonagon.

Scott is saving coins in a jar. Last week, the jar was 1/4 full. This week, he added more coins, and the jar is now 1/2 full. How much of the jar did Scott fill this week?
Answer:
Scott filled (1/2 - 1/4) of the jar, or 1/4 of the jar this week.
Let me know if this helps!
Answer:
He filled his jar 1/4 more this week.
Step-by-step explanation:
The explanation is very simple, you know that he added 1/4 coins last week and this week he added more coins that filled the jar half way:
1/2 - 1/4 = 1/4
or you can also use:
1/4 + 1/4 = 1/2
Samuel says that 25% is greater than 0.3.
Is he correct? Explain your answer.
Answer: No 0.3 as a percentage is larger than 25%
Step-by-step explanation:
'percent' is 'over hundred'
if you convert 0.3 into a percentage it becomes 30 percent
Samuel says that 25% is greater than 0.3 is not correct statement.
What is Percentage?A percentage is a number or ratio expressed as a fraction of 100.
The percentage is denoted by the symbol %.
The percentage is used or most important application is to compare any two quantities. We compare one quantity against another, with the second quantity rebased to 100 by using percentage.
Samuels says that 25% is greater than 0.3 is a false.
25% when it is converted to decimals.
25 divided by 100
we will get 0.25
and if 0.3 is converted to percentage
0.3×100=30%
We know that 30% is greater than 25%.
hence Samuel says that 25% is greater than 0.3 is not correct.

Find the measure of angle C
show work and explain!
Answer:
Angle C = 45°
Step-by-step explanation:
Hello There!
If you didn't know opposite angles are congruent in parallelograms
So ∠A≅∠C and ∠B≅∠D
So if ∠A = 45° then ∠C also equals 45°
As it is a parallelogram

[tex]\\ \sf\longmapsto <A\cong <C[/tex]

How do you create a linear inequality in two variables?
A. The set of all the points on one side of a line.
B. Change the symbol = to > or <.
C. An ordered pair of real numbers with the following property: When the x-coordinate is substituted for x and the coordinate is substituted for y in the inequality, we obtain a true statement.
D. If the original inequality contains a < or > symbol.
F. If the original inequality contains a less than, equal to or greater than, equal to symbol.
Linear inequalities with two variables have infinitely many ordered pair solutions, which can be graphed by shading in the appropriate half of a rectangular coordinate plane. To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality.

Question 1 options:

2)
183.5°
3)
176.5°
4)
91.75°
Answer:
4) 91.75
Step-by-step explanation:
7x+20+9x-4=180
16x=164
x=10.25
7(10.25)+20=
71.75+20=91.75
Answer:
You are correct 91.75 is the answer
Step-by-step explanation:
This is a cyclic quadralterial since all the. vertices of the quadralterials touch the circle circumference. Opposite angles are supplementary in cyclic quadralterials. Angle C and Angle D are opposite angles so
[tex]7x + 20 + 9x - 4 = 180[/tex]
[tex]16x + 16 = 180[/tex]
[tex]16x = 164[/tex]
[tex]x = 10 \frac{4}{16} [/tex]
[tex]x = 10.25[/tex]
Plug 10.25 into 7x+20
[tex]7(10.25) + 20 = 91.75[/tex]
