Answer: <u>276 miles in 5 hours and 45 minutes</u>
5 x 48 = 240
240 + 36 = 276
Answer:
The ratios must be 88% of grade A sugar and 12% of grade B sugar.
Step-by-step explanation:
On the grade A every kg costs £75, while on the grade B every kg costs £50. The final mixture we want to make needs to cost £72 per kg. We will sum a certain mass of grade A, "x", with a certain mass of grade B, "y". The sum of these masses must be equal to 1 kg. So we have:
Since we want the final mixture to cost £72, we need to satisfy:
Solving the system of equation will reveal the ration that must be used.
The ratios must be 88% of grade A sugar and 12% of grade B sugar.
Answer:
1. x = 10
(triangle has equal side lengths)
2. x = the same number inside the triangle
(is that a 40 or 80?)
3. x = 34
(is that a 34?)
4. x = the number shown on the other side of the triangle
(is that a 55?)
5. if the given number is 8 then x = 11
(11-3=8)
6. x = 11
(2x-15=7)
7. x = 5
(65+5=70)
8. x = 10
(5x-10=40)
9. m<2 = 9
(7x-3=60)
10. m<2 = 8
(x+72=80)
hope this helps!
Answer:
x=2
y=4
3 times 4 equals 12 and 2 plus 4 would equal six
