The answer is 8 because 8 x 8 = 64 If you see these kinds of problem what is the square root of 25, 64, 36... means 5 x 5 = 25, 8 x 8 = 64, 6 x 6 = 36 If you see square root of 48. It would come out to be a decimal number.
Answer:
2 yards
Step-by-step explanation:
Answer:
x = -6, y = 12
Step-by-step explanation:
Equations:
y = 2x + 24
y = -2x
Bring the the equation together and add like terms together:
-2x = 2x + 24
-4x = 24
Divide both sides by -4 to isolate x:
![\frac{-4x}{-4} = \frac{24}{-4} \\\\x = -6](https://tex.z-dn.net/?f=%5Cfrac%7B-4x%7D%7B-4%7D%20%20%3D%20%5Cfrac%7B24%7D%7B-4%7D%20%5C%5C%5C%5Cx%20%3D%20-6)
Find y:
y = -2(-6)
y = 12
Verify:
12 =2(-6) + 12

Responder:
16 kg y 4 kg
Explicación paso a paso:
Deje que las suelas individuales se representen como ayb
Como queremos obtener un ingrediente de 20 kg en total, entonces;
a + b = 20 .... 1
Si estamos mezclando una cantidad adecuada para 800 y 550 por kg a 600 por kg, entonces;
800a + 500b = 600 (20)
800a + 550b = 12000
80a + 55b = 1200
16a + 11b = 240 .... 2
Resuelve 1 y 2 simultáneamente
a + b = 20 .... 1 × 16
16a + 11b = 240 .... 2 × 1
______
16a + 16b = 320
16a + 11b = 240
Sustraer
16b-11b = 320-240
5b = 80
b = 80/5
b = 16
Sustituya b = 16 en la ecuación 1
a + b = 20
a + 16 = 20
a = 20-16
a = 4
Por lo tanto, se utilizaron 16 kg del primer ingrediente y 4 kg del otro ingrediente.
