At a food festival, 3/8 of the dishes were from china. Another 12.5% of the dishes were from japan. What percent of the dishes w
MrMuchimi

Answer: 50%

Step-by-step explanation:

Let x = Total dishes.

Dishes from China = \dfrac38x

Dishes from Japan  = 12.5\% \text{ of }x= 0.125x

Total dishes  from China and Japan = \dfrac38 x+0.125x=0.375x+0.125x=0.5x

Dishes from other countries = x- 0.5x= 0.5x

Percent of dishes from other countries= \dfrac{0.5x}{x}\times100\%= 50\%

Hence, dishes from other countries = 50%

Four times a number added to 3 times a larger number is 31. Seven subtracted from the larger number is equal to twice the smalle
aev [14]
Let the smaller number be x.
Let the bigger number be y.

\begin{cases} &4x + 3y = 31 \tex{ ----- (1) } \\ &y- 7 = 2x \tex{ ----- (2) } \end{cases}

Rearrange equation (2):
\begin{cases} &4x + 3y = 31 \tex{ ----- (1) } \\ &y = 2x + 7 \tex{ ----- (2) } \end{cases}



Sub (2) into (1):

4x + 3(2x + 7 ) = 31
4x + 6x + 21 = 31
10x + 21 = 31
10x = 10
x = 1

Sub x = 1 into (2):

y = 2x + 7
y = 2(1) + 7
y= 9

Answer: The two numbers are 1 and 9.

What is the answer for this one ??
Arisa [49]

Answer: D

Step-by-step explanation:

A. 3 + -7 < -4

    -4 < -4

        X

    this one isn’t a solution

B. 3 + -7 ≤ -4

   -4 ≤ -4

   this works, let’s try the other equation

   3(3) + 2(-7) < -5

    9 + -14 < -5

     -5 < -5

       X

     this one doesn’t work either, let’s go on to the next one

C. the first equation is the same as the first one in A, and that didn’t work, so we know that the whole thing doesn’t work and we don’t have to do any math

D. we know the first equation works because we did it in B

    let’s go on to the second equation

    3(3) + 2(-7) ≤ -5

     9 -14 ≤ -5

     -5 ≤ -5

      this works, so that means that both equations work and the whole thing works :)
