Answer:
No Solution
Step-by-step explanation:
26 + y = 8
-26
y = -18
proof 26 + (-18) = 8
83 - y = 2
+83
-y = 85
*-1
y = -85
-18 does not = -85 and I don't see an X in your system of equations
In one round of a television game show, five questions are asked. The second question is worth twice as much as the first. The third question is worth three times as much as the second. The fourth question is worth four times as much as the third. The fifth question is worth five times as much as the fourth. If the fifth question is worth $12,000, what is the first question worth?
Answer:
$100
Step-by-step explanation:
1st q. 2nd q. 3rd q. 4th q. 5th q
x. 2x. 3(2x)=6x. 4(6x)=24x. 5(24x)=120x
100. 200. 600. 2400. 12000
since the 5th q was worth 12000 we know:
120x = 12000
x = 100
Rachel left home for school at 7:45 one morning. She returned home at 4:05 that afternoon. How many hours and minutes was she gone? (The number of minutes in your answer must be less than 60.)
Answer:
8 hours 20 minutes
Step-by-step explanation:
Given that :
Time Rachel left for school = 7:45 a.m
Time she returned Home = 4:05 p.m
Time for which Rachael was gone :
4:05 p.m - 7:45 a.m
7:45 a.m to 3:45 p.m= 8 hours
3:45pm to 4:05 pm = 20 minutes
= 8 hours 20 minutes
Rachael was gone for 8 hours 20 minutes
JUST REPOSTING THIS QUESTION UNTIL I GET A CORRECT ANSWER lol!
Answer:
3x+(8x+15=180
3x+8x+15)=180
11x+15=180
11=180-15
11x=165

3(2m + 1) + 5m
Answer:
The simplified answer is 8m+3.
Step-by-step explanation:
3(2m+1)+5m
(6m+3)+5m
8m+3
Answer:
11m + 3
Step-by-step explanation:
First you distribute:
3 ( 2 + 1 ) + 5
6m + 3 + 5m
Next, you combine like terms:
6m + 5m + 3 = 11m + 3

The segments formed by the altitude to the hypotenuse of a right triangle are 8 and 10. Find the shorter leg of that triangle.
Answer: 6
Step-by-step explanation:
Since the hypothenuse is 10 and the larger leg of the triangle is given as 8, the shorter leg will be calculated as the square of the hypothenuse minus the square of the longer leg after which we find the square root of the value gotten. This will be:
Shorter leg² = 10² - 8²
Shorter leg² = 100 - 64
Shorter leg² = 36
Shorter leg = ✓36
Shorter leg = 6

PLZZZ HELP MEE ILL GIVE BRAINLIEST AND 50 POINTS!!!
Answer:
The answer would be 45.
Step-by-step explanation:
5*9=45
Answer:
45
Step-by-step explanation:
First we count how many people he split it between which is 5 and we have to remember the key word here is equal so if he was left with 9 then everybody else did as well. so we multiply 5 times 9 which is 45
Is value of X in the equation 6x+3+4x= 1/2(9+10x)
Answer:
x = 0.3
Step-by-step explanation:
6x + 3 + 4x = 1/2 (9 + 10x)
=> 10x + 3 = 1/2 *9 + 5x
=> 5x + 3 = 9 / 2
=> 5x = 9 / 2 -3
=> 5x = (9 - 6) / 2
=> 5x = 3 / 2
=> x = 3 / 10
=> x = 0.3

X does not equal to -5,-2,-4
Step-by-step explanation:
Factor out the denominators and use inequality.
X+5=0 -> X=-5
X^2+6X+8=(X+2)(X+4)
X+2=0 ->X=-2
X+4=0 -> X=-4

Lucy, Luke, and Lilly went trick-or-treating on Halloween. After they finished, they compared the amount of candy they all had. Luke had twice the amount Lilly had, and Lucy had 15 less than 3 times the amount Lilly had. If together, they had 225 candies, how many candies did Lucy have? PLEASE HELP URGENT
Hi there!
Let think talk about these clues we have right now...
Luke is x2 more than Lily.
Luce is 45 less candy than Lily since 3 times 15.
225 candys in total...
Let make a random guess...
Lily: 70
Luke: 140
Lucy: 35
Total: 245
Now we know that there must be a half candy since it’s a odd number at the end of that...
Lily: 67.5
Luke: 135
Lucy: 22.5
Total: 225
But we are asked for only Lucy...
So the answer to this problem is 22.5.

15. Considera um losango em que uma diagonal tem 8cm e cuja área é 12cm^2. Qual é o comprimento do lado do losango, arredondado às décimas? Nota: Indica apenas o valor numérico usando algarismos. (Não escrevas unidades de medida na resposta.)
Answer:
4,3cm
Step-by-step explanation:
Passo 1
Um losango tem 2 diagonais, cujos comprimentos não são iguais
Temos que encontrar o comprimento da segunda diagonal
A fórmula é dada como:
Área de um losango = 1/2 (d1 × d2)
Área do losango = 12 cm²
d1 = Comprimento da primeira diagonal = 8cm
d2 = Comprimento da segunda diagonal = x
12 = 1/2 (8 × x)
12 = 1/2 (8x)
12 = 4x
x = 12/4
x = 3cm
O comprimento da segunda diagonal = 3 cm
Passo 2
A fórmula do comprimento da lateral de um losango é dada como:
s = √d1² + d2² / 2
d1 = 8cm
d2 = 3 cm
s = √8² + 3² / 2
s = √64 + 9/2
s = √73 / 2
s = 8,5440037453 / 2
s = 4,2720018727 cm
Aproximadamente = 4,3 cm
Triangle ABC is a right triangle.
m∠A=5x°
m∠B=(3x−4)°
m∠C=90°
What is the value of x?
Answer:
x = 11.75
Step-by-step explanation:
m∠A + m∠B must equal 90
5x + 3x - 4 = 90
8x = 94
x = 11.75

Kenneth Drew a scale drawing of an apartment the scale of the drawing was 2 meters:1 meter the living room is 6 m long in real life how long is the living room in drawing
Answer:
3 meters
Step-by-step explanation:
Given the scale drawing :
2m : 1m
Length of living room in real life = 6 m long
2 meter = 1 meter
Real life = scale drawing
If length = 6 meter long ;
using cross multiplication :
2 meter = 1 meter
6 meter = x
2x = 6
x = 6/2
x = 3 meter
Length of living room in drawing = 3 meters
