The answer is <span>He subtracted 10 from the right side instead of adding 10 to the right side
Let's solve it:
</span><span>2x + y = 5
x − 2y = 10
________
Rearrange first equation to get y:
y = 5 - 2x
________
Substitute y into the second equation:
x - 2(5 - 2x) = 10
________
Multiply the terms:
x - 10 + 4x = 10
________
Combine the terms:
5x - 10 = 10
________
Add 10 on the both sides of the equation:
5x = 10 + 10
5x = 20
x = 4</span>
Answer:
A = 201 cm²
Step-by-step explanation:
We know that the area of a circle can be calculated with the formula:
A = πr² = π(d/2)²
with d being the diameter.
Therefore:
A = 3.14(8cm)² = 201 cm²
1/4+1/4+1/4+1/4+1/4+1/4+<span>1/4+1/4 = 8 Miles
1/4+1/4 = 1/2 Mile
1/2+1/2 = 1 Mile
1+1 = 2 Miles</span>
2,213,000, 6 is closer to 10 than 0.
"a" and integer is a whole number not a fraction or a decimal
