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.
Answer:
y=3÷9
Step-by-step explanation:
2x-9y=11
or,2×7-9y=11
or,14-11=9y
or,3÷9=y
2x - 3 [5x - 2(6-x)] =
2x - 3 [ 5x - 12 + 2x ] =
2x - 3 [ 7x - 12 ] =
2x - 21x + 36 =
-19x + 36
1 2/5 = 7/5
2 3/8 = 19/8
4 1/3 = 13/3
1 2/3 = 5/3
The correct answer would be drawing a line from 4 1/3 to 13/3.
