It’s easy do 2 times 14 so it’s 28
For 15 the answer is 8
for 16 the answer is 9
for 17 the answer is 1
Step-by-step explanation:
-9×(-87)=783
783÷(-9)=-87
-2y + 6 < 10
Subtract 6 on both sides
-2y < 10
Divide by -2 on both sides
y > -5
Hope this helps! Just in case you don’t understand the final answer, when dividing or multiplying by a negative number you flip the sign!
Answer:
6/21.
Step-by-step explanation:
let the rational number be 2x/7x.
2x + 4 / 7x - 2 = 10 /19
Cross multiply:
19(2x + 4) = 10(7x - 2)
38x + 76 = 70x - 20
96 = 70x - 38x
32x = 96
x = 3.
So the rational number is 2*3/ 7*3
= 6/21.
