Step-by-step explanation:
Answer:
The first one
Step-by-step explanation:
-2x + 6y = -34
-x + 3y = -17
x = 3y +17
Sub this into 1st eqn
5(3y + 17) + 2y = 21
15y + 85 + 2y =21
17y = -64
y = -3.7647 (to 5 sig. fig.)
y = -3.8 (to nearest tenth)
Sub y = -3.7647 into 2nd eqn
x = 3(-3.7647) +17
x = 5.7 (to nearest tenth)
Convert G to kg
560/1000=.56 kg a day
If the bake off was 5 days
.56*5= 2.8kg... per week
2.8kg*3= 8.4 kg for 3 weeks
If it was 7 days
.56*7 = 3.92 kg per week
3.92*3= 11.76 kg for 3 weeks
Dont quote me on this but i think it is 10 because 86 × 2 is 172 and 297 ÷ 172 is 10 I think
