Jakob is buying juice boxes for the after school program. On Monday, he
purchases 4 apple juices and 1 berry juice for a total of $13.25. On
Wednesday, he purchases 8 apple juices and 5 berry juices for a total of
$36.25. Determine the expression you are left with if you eliminate x. *
O
3y = 9.75
12x + 6y = 49.50
O
7y = 62.75
O
3y = 49.50

Step-by-step explanation:

Cost of apple juice = x

Cost of berry juice = y

4x + y = 13.25(i)

8x + 5y = 36.25 (ii)

Multiply (i) by -2

(i)*(-2)       -8x - 2y = -26.50

(ii)              8x + 5y = 36.25             {Now x will be eliminated}

                       3y =  9.75

3y = 9.75        

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
