Let first number =a
Let second number = b
a =b+ 19
:b+b+19=43
2b+19=43
2b=43-19
2b=24
b=24/2
b=12
a=b+19
=12+19
=31
Check:31+12
=43
Answer:
nope it is equal to 84/100 though
Step-by-step explanation:
cross multiply
21 x
-------- -----------
25 100
21*100= 2100
2100/25= 84
x=84
I hope this helped!
Answer:
y = 2x + 5
Step-by-step explanation:
y = mx + b : Slope Intercept Form
Our m (slope) does not change, but our b (y-intercept) does.
Step 1: Plug in all numbers except b
y = 2x + b
3 = 2(-1) + b
Solve
5 = b
Step 2: Add slope and intercept into equation
y = 2x + 5
It's like simple math but the sign of the answer would be the opposite.
|−19−(−14)|
|−19 + 14|
|- 5|
|- 5| = 5
