Using the two given equations:
x - y = 34
x +y = 212
Rewrite the first one in terms of x:
x = 34 + y
Now replace x in the 2nd equation:
34 + y + y = 212
Simplify:
34 +2y = 212
Subtract 34 from both sides:
2y = 178
Divide both sides by 2:
y = 178/2
y = 89
Now replace y in an equation to solve for x:
x + 89 = 212
x = 212-89
x = 123
He has 123 domestic stamps and 89 foreign stamps.
Answer:
the first one is 2.5, because if you divide the blue in half, you need to divide the yellow in half too
Answer 2:
copy and paste what i write or something:
3+2+1+1= 1 plum purple gallon. So for 3 gallons, you multiply each by 3.
So, Red tint=9
Blue tint=6
Yellow tint=3 and
White tint=3
I think it would be a triangle, because they said it would be cut at an angle.
Answer: Whats the Question?
Step-by-step explanation:
Answer:
t=45
Step-by-step explanation:
-3=t/-15 step one multiply both sides by denominator
-3 x -15 = 45
