2 consecutive even integers : x and x + 2
4(x) + 3(x + 2) = 20
4x + 3x + 6 = 20
7x + 6 = 20
7x = 20 - 6
7x = 14
x = 14/7
x = 2
x + 2 = 2 + 2 = 4
so ur first number (x) = 2 and ur second number (x + 2) = 4
Answer:
Step-by-step explanation:
IIada, Distance = speed*time, so speed = distance/time right?
The plane went the same distance each direction.
s - w = 40/30 = 4/3
s + w = 40/20 = 2
Adding the two equations together...
s = 5/3
w = 1/3
So the speed of the wind in miles per hour is 1/3
Answer: -6/7
Step-by-step explanation:
3(5f+2)-f=2(-3)
15f+6-f=-6 ⇔ distributive property
14f+6=-6 ⇔ subtract f from 15f
14f=-12 ⇔ subtraction property of equality (subtract 6 on both sides)
f=-12/14 ⇔ division
f=-6/7
Hope this helps!! :)

Answer:
The number is 25
Step-by-step explanation:
Of is multiply and is means equals
70% *W = 17.5
Change to decimal form
.70 W = 17.5
Divide and .70
.70W/.70 = 17.5/.70
W =25
Both heads and tails because there are only 2 choices
