Answer:
7
Step-by-step explanation:
To solve this problem we need to find x
First we need to do parenthesis
This means that the equation becomes 5x - 2x - 2 = x + 3x + 5
Next add or subtract, this simplifies it to 3x - 2= 4x + 5
After this bring the numbers on the right and the variables on the left
This means subtracting 4 on each side and adding 2 on each side
Now the equation becomes -x = 7
Lastly, put the negative on the right
x = 7
Answer:
6 minutes
Step-by-step explanation:
Mr Crenshaw checks at a rate of 1/10 and Mr. Aguirre checks at a rate of 1/15.
If they work together, they will be checking at a combined rate of:
1/10 + 1/15 = [3(1) + 2(1)]/30
= 5/30 = 1/6
Their combined rate is 1/6 which means they check one set in 6 minutes
Answer:
Slope = -3/5
Step-by-step explanation:
slope (m) = y2 - y1 / x2 - x1
m = -2 - 1 / 1 - -4
m = -3 / 1 + 4
m = -3 / 5
You can check the work by counting rise (-3 which means 3 units down) over run (5 which means 5 units to the right)
Responder:
240 huevos
Explicación paso a paso:
Número de cajas de huevos = 4
Huevos por caja = 50
Total de huevos en caja = 50 * 4 = 200 huevos
Número de cajas = 3
Número de huevos por caja = 10
Total de huevos en caja = 10 * 4 = 40 huevos
Huevos totales = (huevos en caja + huevos en cartón)
Total = (200 + 40) = 240 huevos
Answer:
Step-by-step explanation:
b). Since relation between the number of spring rolls and number of people is,
Number of spring rolls ∝ Number of people
Therefore, Number of spring rolls (R) = k × Number of people (P)
With the help of this proportional relation,
If the number of spring rolls (R) are 6 and the number of people (P) are 3.
6 = 3k
k = 2
So the equation that defines the relation will be,
R = 2P
a). For R = 1,
1 = 2P ⇒ P = 0.5
For R = 10,
10 = 2P ⇒ P = 5
For R = 16,
16 = 2P ⇒ P = 8
For R = 25,
25 = 2P ⇒ P = 12.5
For R = n,
n = 2P ⇒ P =
