Identify a pattern and find the next number in the pattern. –48, –24, –12,

To French shop for fresh fruit. Elena buys a watermelon for $7.75 and 5 pounds of cherries Tammy buys a pineapple for $4.15 and

lys-0071 [83]

Answer: Elena spent $3.6 +x more than Tammy.

Step-by-step explanation:

Let the cost of each cherry be 'x'.

Cost of watermelon for Elena = $7.75

Cost of 5 pounds of cherries = 5x

So, Equation for Elena would be

$7.75+5x$

Cost of pineapple = $4.15

Number of pounds of cherries = 4

So, Equation for Tammy would be

$\$4.15+4x$

Now, Elena spent more than Tammy by

$(7.75+5x)-(4.15+4x)\\\\=7.75+5x-4.15-4x\\\\=3.6+x$

Hence, Elena spent $3.6 +x more than Tammy.

Use the elimination method

Natalija [7]

1) 3x+y=-1 5x-y=9
First of all we have add both equation but to be sure that the value we want to eliminate are both in a way that would make it possible t be deleted.
 3x+y=-1
 5x-y= 9
8x = 8
x= 1
In this case we are able to eliminate y becuase if we add +y-y we get that our answer is 0. and 3x + 5x would be 8x and -1+9 would be equal to 8 and to find x we needed to divided giving us that the answer for x is 1 becuase 8/8 is 1.
Then to find y we substitude the value of x in any of the formulas.
3(1)+y= -1
3+y= -1
y= -1-3
y=-4
When we have our y value we can determine if it is correct by replace the values.
5(1)--4= 9
5+4= 9
9=9
Up until now we are fine. So we do the same with the other equation.
3(1)+-4=-1
3+-4=-1
-1=-1
So by this we can now detemine that.
x= 1
y= -4

2) 4x+6y=24 4x-y=10
4x+ 6y =24
4x-y=10 (*-1)
4x+6y=24
-4x+y=-10
7y= 14
y= 14/7
y= 2
In this case we are not able to delete any of the variables so we multiplied by -1 to be able to eliminate x. 
Then to find x we substitute the value of y in any of the formulas.
4x-2=10
4x= 10+2
x= 12/4
 x= 3
So we now know our variables so we substituted them to see if they are correct.
 4(3)+6(2)=24
12+12=24
24=24
We do the same with the other equation.
 4(3)-2=10
12-2 =10
 10= 10
So we can assume that.
x= 3
y= 2

3)2x-y=-3 x+3y=16
(3*)2x- y= -3
x+ 3y = 16
6x -3y = -9
x+3y =16
7x= 7
x= 1
In this case we are not able to delete any of the variables so we multiplied by 3 to be able to eliminate y. 
Then to find y we substitute the value of x in any of the formulas.
 1+ 3y = 16
3y= 16-1
y= 15/3
y= 5
So we now know our variables so we substituted them to see if they are correct.
2(1)- 5 =-3
2-5= -3
-3= -3
We do the same with the other equation.
1+3(5)= 16
1+15=16
16=16
So we now are sure that
x= 1
y= 5

4) 2x+3y=7 3x+4y=10
2x+3y =7 ( * - 4)
3x+4y =10 ( * 3)
-8x -12y = -28
9x +12y = 30
x= 2
In this case we are not able to delete any of the variables so we multiplied one of teh quations by - 4 to be able to subtract in our sum and the other by 3 to have the same number on y to be able to eliminate y. 
Then to find y we substitute the value of x in any of the formulas.
2(2)+3y= 7
4+3y=7
3y= 7-4
y= 3/3
y= 1
So we now know our variables so we substituted them to see if they are correct.
3(2)+4(1)= 10
6+4=10
10=10
We do the same for the other
2(2)+3(1)=7
4+3= 7
7=7
So with that we can say that.
x= 2
y= 1

Answer:

Step-by-step explanation:

you first mulitply the denomenater by the whole number and add the numerator.

Than you flip the second fraction and muliply the two fractions together.

And then you simplify the fraction if you can.
