Answer:
A
Step-by-step explanation:
x^a/x^b=x^(a-b). General rule of exponents
Answer:
The system of equations is the option A
Step-by-step explanation:
Let
x ------> the number of tickets for the roller-coaster
y ------> the number of tickets for the bumper
z ------> the number of tickets for the Ferris wheel
we know that
The system of equations is equal to
<em>John</em>
2x+3y+z=42
<em>Darren</em>
3x+y+2z=36
<em>Shelley</em>
x+2y+3z=32
therefore
The system of equations is the option A
Hello :
<span>8(j-4)=2(4j-16)
</span><span>2(4j-16)= 2(4(j-4))=8(j-4)
</span>8(j-4)= 8(j-4)....(identity : infinty solutions)
Complete question is;
Keisha needs to make at least 32 costumes for the school play. Since she can make 4 costumes each week, Keisha plans to work on the costumes for at least 8 weeks.
Which inequality matches the problem?
A) x ≥ 8
B) x = 8
C) x ≤ 8
D) none of the above
Answer:
A: x ≥ 8
Step-by-step explanation:
Let the number of weeks be x.
She needs to make at least 32 costumes and plans to work at least 8 weeks. Since she makes 4 costumes per week, we can say that;
4x ≥ 32
I used greater than or equal to sign because she can't make less than 32 costumes.
Also, she can't use less than 8 weeks.
Thus; dividing both sides by 4, we have;
4x/4 ≥ 32/4
x ≥ 8
