Answer:
4a) 
· (5 + 7)
b) 3 ÷ (3/5)
c) ( - 
) ÷ 3
Step-by-step explanation:
-1/5 * n ≤ 17
n ≥ -17/5 is the answer
Answer:
-31
Step-by-step explanation:
a - 8x will change to (-7) - 8(3) = -31
The puppy weighs 15.4 pounds, 40% of 11 is 4.4 so add that to the wight and its 15.4
The answers to each of the given problems are;
1) Sum of two smallest integers = 23
2) 3x + 6
3) 7.5 m/s²
<h3>How to find the sum of consecutive Integers?</h3>
1) We are told that sum of 4 consecutive integers is increased by 20 and equals 70. Thus, we have;
x + (x + 1) + (x + 2) + (x + 3) + 20 = 70
4x + 26 = 70
4x = 70 - 26
4x = 44
x = 44/4
x = 11
Thus, sum of two smallest integers = 11 + 11 + 1 = 23
2) Let the consecutive odd numbers be;
x, (x + 2) and (x + 4)
Sum of these consecutive odd numbers is;
x + x + 2 + x + 4 = 3x + 6
3) We are given the equation to find the acceleration as;
(v_final)² - (v_initial)² = 2ad
We are given;
v_final = 40 m/s
v_initial = 10 m/s
d = 100 m
Thus;
40² - 10² = 2a(100)
1500 = 200a
a = 1500/200
a = 7.5 m/s²
