Dory biked 11 times as many miles as carly. together they biked a total of 156 miles. how many miles did dory bike?

143 miles

Step-by-step explanation:

d = dory

c = carly

first, we find the equation from our question:

11c + c = 156

now solve:

11c + c = 156 (add 11c and c)

12c = 156 (divide both sides by 12)

c = 13

since dory bike 11 times that, just multiply 11 and 13 to get the

11 • 13 = 143

dory biked 143 miles

to check:

c +d = 156

13 + 143 = 156

156 = 156 ✅

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
