Answer: $1.67
Let's make an equation for the problem. To find the price for each sushi roll, divide the price by the number of sushi rolls.
30.06 ÷ 18 = 1.67
uhhhhhhhhhh, i think it's 6? im not sure, i dont see the full photo but ig.
The triangle must be isosceles. because they have 2 same angles. The two sides of the triangle has to be congruent. 3×5=15, 10+5=15
15=15. the answer would be C.
Answer:
they get 8.27$ back.
Step-by-step explanation:
Cost of lunch=$7.29+$8.45+$5.99
=$21.73
3 of them put $10 each=$10×3
$30
Total change they got back=$30-$21.73
=$8.27
Mark as a brainest answer ok
1) -3x-4y=10 ==> - 3x = 10+4y ===> 3x= -10-4y==> x=(-10-4y)/3
Now replace x by its value in 2)
2) -6x+y=-16 ==> - 6[( - 10- 4y)/3] + y = -16 ==> -2[(-10-4y] +y =- 16
+20+8y+y =- 16==> 9y = - 16 - 20 ==> 9y = -36 & y = - 4.
Now replace y by (- 4) in any of the 2 equations & you will find x = 2
