solve the following equation: x2-5=7
Answer:
x= 6
Step-by-step explanation:
Step 1: Write equation
2x - 5 = 7
Step 2: Solve for x
Add 5 to both sides: 2x = 12
Divide both sides by 2: x= 6
Step 3: Check
Plug in x to verify if it's a solution.
2(6) - 5 = 7
12 - 5 = 7
7 = 7

Solve from question 1 to 10 ( I NEED THIS ASAP! TY )
Answers:
1. 65 + x = 90
x =25
2. 51 + x = 180
x =129
3. 107 + x = 180
x = 73
y = 107
z = 73
4. angle + 13 = 180 (supplementary means 180)
angle = 167
5. angle + 38 = 180 (supplementary means 90)
angle = 52
6. (5x + 9) + (3x +11) = 180
8x + 20 = 180
8x = 160
x = 20
angle 1 = 109 angle 2 = 71
7. 17x + 1 = 20x - 14
1 = 3x - 14
15 = 3x
5 = x
angle 1 = 86 angle 2 = 86
8. (3x + 3) + (10x - 4) = 90
13x -1 = 90
13x = 91
x = 7
angle 1 = 24 angle 2 = 66
9. p = 2q - 3; q + p = 180
p = 2(180 - p) - 3
p = 360 - 2p - 3
3p = 357

______________
q + (119) = 90
q = 61
10. b = 3c + 2; b + c = 90

How to know or understand easly variable which number will be in place alphabet for example, in the equation 2x + 3 = 11
Answer:
Step-by-step explanation:
a variable can have any value depending upon the equation
for example,
in 2x + 3 = 11
2x = 11 - 3
2x = 8
x = 8 / 2
x = 4
Hope this helps
plz mark as brainliest!!!!!!!
Step-by-step explanation:
Hey there!
Variables have the unknown value.
If you want to find or know value from the equation easily, you have to simply solve the equation.
For your example;
2x+3=11
Now, solve it to get value of variable 'x'.
2x = 11-3
2x = 8
[tex]x = \frac{8}{2} [/tex]
Therefore the value of variable 'x' is 4.
Hope it helps...
Consider the equation below. -2(5x + 8) = 14 + 6x
Answer:
-1.875
Step-by-step explanation:
1. Write the problem: -2(5x + 8) = 14 + 6x
2. Multiply -2 by 5 and 8 to get: -10x - 16 = 14 + 6x
3. Combine like terms: -16x - 16 = 14
4. Repeat step 3: -16x = 30
5. Divide -16 by 30 to get the answer which is -1.875.
Hope this helped!

1. Un edificio proyecta una sombra que mide 8 m de largo (Fig. 1.32). Se sabe que
la línea que va desde la punta de la sombra proyectada hasta el sol forma un án-
gulo de 30º con respecto del piso; y si a 1.5 m de distancia de donde termina la
sombra del edificio se alza una vara vertical (apoyada en el piso) de 50 cm de alto
cuyo extremo superior coincida con la línea mencionada:
¿Cuál es la altura del edificio?
Answer:
El edificio tiene aproximadamente 2,67 metros de altura
Step-by-step explanation:
La información proporcionada son;
La longitud de la sombra proyectada por el edificio = 8 m
El ángulo formado por la línea que va desde la punta de la sombra al Sol = 30 °
La ubicación del poste vertical desde la punta de la sombra = 1,5 m
La altura del poste vertical = 50 cm = 0,5 m
Por tanto, tenemos por triángulos semejantes formados por la punta de la sombra, la altura del poste vertical y la altura, h, del edificio la siguiente relación;
Bronceado (30 °) = h / 8 = 0,5 / 1,5
h = 8 × 0.5 / 1.5 = 8/3 m = ≈ 2.67 metros
La altura del edificio es de aproximadamente 2,67 metros.
