Step-by-step explanation:
1.3z + 1.5 = 5.4
Make z the subject in the equation by making it stand alone, by so doing, the transferred figures will have a change in sign i.e if it's a negative sign that's gonna be transferred it will change into a positive sign and vice versa.
The equation will this be; 1.3z = -1.5 + 5.4
1.3z = 3.9
Divide both sides by the co-efficient of the unknown figure. In other words, you'll divide both sides by the number beside the unknown letter.
z = 3.
Answer:
g(x)=22
Step-by-step explanation:
Substitute -4 into the equation.
g(x)= -5x+2
g(-4)= -5(-4)+2
g(-4)= 20+2
g(-4)= 22
Divide by 11 to make z by itself
z = 4/11
To convert from a decimal to a percentage, you must multiply the decimal by 100. Therefore, we do 1.46 x 100 = 146% Therefore A is the correct answer.
Answer:
2(y-3)=7+2y-3
Step-by-step explanation:
