Answer:
Class A, by 3.5 × 10³ points
Step-by-step explanation:
When comparing numbers in scientific notation, the one with the largest exponent will be the largest. When two numbers have the same exponent (as here), then the one with the largest mantissa is the largest.
3.54 × 10^5 is the largest of the given numbers. It is the number of points earned by Class A.
Class C earned the second-largest number of points, 3.505 × 10^5. The difference of these two numbers is ...
... 3.540 × 10^5 - 3.505 × 10^5 = (3.540 -3.505) × 10^5
... = .035 × 10^5 = 3.5 × 10^3

First to answer
Answer:
A. The coefficients of z are the same, but the constant terms are different.
Step By step Explanation:
2(z – 1) = 4(z + 5)
Step 1: Simplify both sides of the equation.
2(z−1)=4(z+5)
(2)(z)+(2)(−1)=(4)(z)+(4)(5)(Distribute)
2z+−2=4z+20
2z−2=4z+20
Step 2: Subtract 4z from both sides.
2z−2−4z=4z+20−4z
−2z−2=20
Step 3: Add 2 to both sides.
−2z−2+2=20+2
−2z=22
Step 4: Divide both sides by -2.
−2z/−2 = 22/−2
z=−11
The coefficients for z are the same, but the constants are different.
The number is 6. 8*7=56, 9*7+5=68, 6860.
