2x + y = 7
substitute
2x + (x+1) =7
combine like terms
3x+1 =7
subtract 1 from each side
3x =6
divide by 3
x=2
y = x+1
y =2+1
y=3
Answer: x=2, y=3
-1, 5/2
And in decimal form 1, 2.5
The correct answers would be :
2.) 2.6 < 2.7
1.2 < 1.9
10.7 > 10.4
3.) D.
4.) A. (97÷33)
So, we have the information:
Save $10 first month
$5 the next months
X = amount of months
Cost = 175
So, it will take 7 months.
10+15+20+25+30+35+40 = 175
Answer:
The answer is 7 candies for each friend with a remainder of 3. If you are taking or have taken decimals i suggest you write 7.5 because candy can be split in half.
Step-by-step explanation:
First, multiply 4 by 10. The product is 40. Then, add 5. The sum is 45. Divide 45 by 6. The quotient is 7 with a remainder of 3.
