He has already earned $8 5 times, so we know that he has 8×5=$40. 88-40=48, so he needs $48 more. 48÷8=6, so he needs to walk the neighbour's dog 6 more times to earn that extra $48
Answer:
The solution is any point in the common part of red and blue
The two lines intersect each other at (4 , 7)
Step-by-step explanation:
∵ y > 1/4 x + 6 ⇒ y = 1/4 x + 6
∵ y > 2x - 1 ⇒ y = 2x - 1
∴ 2x - 1 = 1/4 x + 6
∴ 2x - 1/4 x = 6 + 1
∴ 7/4 x = 7 ⇒ x = 7 ÷ 7/4
∴ x = 4
∴ y = 2(4) - 1 = 7
∴ The two lines intersect each other at (4 , 7)
∴ The solution is any point in the common part of red and blue
Area = (1/2) * 4 * 5 = 10 cm²
Answer:
1.) 4 7/15
2.) 2 3/8
3.) 4 7/10
4.) 2 1/3
Step-by-step explanation:
1.) 1 4/5 + 2 2/3
3 + 4/5 + 2/3
LCD = 15
3 + 12/15 + 10/15
3 + (12 + 10)/15
3 + 22/15
3 + 1 7/15
4 7/15
2.) 5 7/8 - 3 1/2
(5 x 8 + 7)/8 - 3 1/2
47/8 - 3 1/2
47/8 - (3 x 2 + 1)/2
47/8 - 7/2
LCD = 8
47/8 - 28/8
19/8
2 3/8
3.) 1 1/2 + 3 1/5
4 + 1/2 + 1/5
LCD = 10
4 + 5/10 + 2/10
4 + (5 + 2)/10
4 7/10
4.) 7 5/6 - 5 1/2
(7 x 6 + 5)/6 - 5 1/2
47/6 - 5 1/2
47/6 - (5 x 2 + 1)/2
47/6 - 11/2
LCD = 6
47/6 - 33/6
(47 - 33)/6
14/6
7/3
2 1/3
