In ∆RST and ∆XYZ
RS=YZ(S)
angle RST=angle XYZ(A)
ST=YZ(S)
hence ∆RST ≠~∆XYZ
eneter the value x that makes the equation true 7x-2(x+1)+18=8x-11
Answer:
7x-2(x+1)+18=8x-11
7x-2x-2+18=8x-11
9x+16=8x-11
x+16=-11
x = -27

A linear sequence (i.e. where the 1st difference is always the same) has 5th term 6 and 92nd term 354. What is the 57th term?
Answer:
I dont know xDDDDDDDDDD
Answer:
a₅₇ = 214
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given a₅ = 6 and a₉₂ = 354 , then
a₁ + 4d = 6 → (1)
a₁ + 91d = 354 → (2)
Subtract (1) from (2) term by term to eliminate a₁
0 + 87d = 348
87d = 348 ( divide both sides by 87 )
d = 4
Substitute d = 4 in (1) and solve for a₁
a₁ + 4(4) = 6
a₁ + 16 = 6 ( subtract 16 from both sides )
a₁ = - 10
Then
a₅₇ = - 10 + (56 × 4 ) = - 10 + 224 = 214
Alex has 128 photos of his friend to display equally in 4 photo albums. Which equation can you use to find how many will be in each album?
Answer:
128 ÷ 4 = [tex]\frac{128}{4}=32[/tex]
Step-by-step explanation:
Total number of photos = 128
Number of photo albums = 4
Alex has 128 photos of his friend to display equally in 4 photo albums.
Equation that can be used to find number of photos in each album =
Number of photo albums ÷ Total number of photos
= 128 ÷ 4
= [tex]\frac{128}{4}=32[/tex]

What is the value of x? (SOMEONE PLEASE HELP ME OUT BRO PLEASEEEEE IGNORE THE 9 smh)
Answer:
x=28
Step-by-step explanation:
Sum of all the angles in the triangle add up to equal 180
90 + x + 6 + 2x = 180
combine like terns
96 + 3x = 180
subtract 96 from each side
180-96=84
96-96 cancels out
3x=84
divide each side by 3
84/3=28
3/3 cancels out
x=28

=========================================
Explanation:
The quadrilateral shown is a kite since we have adjacent sides that are the same length (due to the similar tickmarks). The diagonals of any kite intersect to form a 90 degree angle.
The triangle in the lower left corner has the three angles of
90x+62xThose three interior angles must add to 180. This is true of any triangle.
90+(x+6)+(2x) = 180
3x+96 = 180
3x = 180-96
3x = 84
x = 84/3
x = 28
the cost of 3 DVDs and 4 CDs £62.00. the cost of 4 DVDs and 3 CDs is £64.00.find the cost of each.
hellllp
Answer:
x = 10; y = 8
Step-by-step explanation:
Let
DVDs = x
CDs = y
3x + 4y = 62 (1)
4x + 3y = 64 (2)
Multiply (1) by 4 and (2) by 3 to eliminate x
12x + 16y = 248 (3)
12x + 9y = 192 (4)
Subtract (4) from (3)
16y - 9y = 248 - 192
7y = 56
y = 56/7
y = 8
Substitute y = 8 into (1)
3x + 4y = 62
3x + 4(8) = 62
3x + 32 = 62
3x = 62 - 32
3x = 30
x = 30/3
x = 10
x = 10; y = 8

bonjour, j’ai un dm de math mais je ne comprends pas :
La mère de Julien lui a choisi un forfait de téléphone mobile
à 14,90 €. Elle explique à son fils que, pour ce prix, il peut téléphoner
60 minutes et envoyer 30 SMS. S'il dépasse son forfait, cela lui
coûtera 0,36 € par minute supplémentaire et 0,12 € par SMS
supplémentaire.
On note t (en minutes) la durée totale pendant laquelle Julien a téléphone et s le nombre total
de SMS qu'il a envoyés. En supposant que Julien dépasse à la fois les 60 min et les 30 SMS de son
forfait :
1) Exprimer en fonction de t (resp. en fonction de s) la somme supplémentaire que devra payer
Julien en ce qui concerne ses appels (resp. en ce qui concerne ses SMS).
2) En déduire l'expression, en fonction de t et s, de la somme totale que devra payer Julien
en cas de dépassement de son forfait tant au niveau des appels que des SMS.
3) Au cours des quatre derniers mois, Julien a répertorié dans un tableau ce qu'il a exactement
consommé. Recopier et compléter son tableau.

Liu Tse is 6 years older than four times the age of her daughter, Lan. Lan will be 9 years old in 3 years.
Answer:
Well, you have given some information, but you have not said what we are looking for. So, what is the question?
Step-by-step explanation:
Answer:
Liu Tse is 30 years oldStep-by-step explanation:
Lan will be 9 years old in 3 years, so Lan is:
9 - 3 = 6 years old
four times the age of the daughter: 4×6 = 24
6 years older than four times the age of Lan: 24 + 6 = 30
Find the missing angle measure 130
Answer:
x=15
Step-by-step explanation:
Hello there!
the whole angle measure is 89
the given angles are 44 and 30
we need to find x
to do so we subtract the given angles from the total angle measure
x=89-44-30
x=15
I think you might need Desmos for graphing?? Explain your answer!
Yes you are correct! This equation will make a parabola. The width when the arch is at ground level would be the x-intercepts, or zeros, of the parabola.
The vertex point is (0,12)
the axis of symmetry is 0
The zeros are (-4,0) and (4,0)
using the zeros take away the negative because something cant be negative feet wide and add the numbers together (4+4)
Your answer is 8

Bill tiene un trabajo a tiempo parcial y le pagan cada hora la misma cantidad. Cada hora que trabaja aparta $6 para dárselos a su mamá. Bill trabaja 3 horas al día y la cantidad total con que se queda cada día es $24. ¿Cuánto le pagan cada hora?
Answer:
A Bill le pagan $14 cada hora.
Step-by-step explanation:
Para conocer la cantidad que a Bill le pagan cada hora, se define una ecuación.
Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos. Es decir, una ecuación se define como una igualdad establecida entre dos expresiones, en la cual puede haber una o más incógnitas que deben ser resueltas.
En este caso, es conveniente definir la siguiente incógnita:
x: cantidad que le pagan a Bill cada horaSi cada hora que trabaja Bill aparta $6 para dárselos a su mamá, entonces cada hora recibirá: x - 6
Bill trabaja 3 horas al día, por lo que en ese día recibirá 3horas*(x-6). Y si la cantidad total con que se queda cada día es $24, entonces la ecuación a resolver será:
3*(x -6)= 24
Resolviendo, obtienes:
3*x - 3*6= 24
3*x - 18= 24
3*x= 24 +18
3*x= 42
x= 42÷ 3
x= 14
Entonces, a Bill le pagan $14 cada hora.
