X= 8
Y= -7
If you use elimination:
–3y–4x=–11
3y–5x=–61
Add the two equations and get
–9x=–72
Divide by –9 on both sides
X=8
Substitute 8 in for x
–3y–4(8)=–11
Simplify
–3y–32=–11
Add 32 on both sides
–3y=21
Divide by –3 on both sides
Y=–7
Answer: yes
Step-by-step explanation:
Answer:
a. -3.78x-0.84
Step-by-step explanation:
To simplify, combine like terms. Because you're just adding them you don't have to change any signs. Add/subtract the terms with an x, that will give you your first number, then add/subtract the terms without an x to get your second number.
Answer:
That their milkshakes need more caramel or less ice cream.
Step-by-step explanation:
We can see that Ari's numbers for a perfect milkshake gives us a caramel to ice cream ratio of 333 / 555 = 0,6.
But the Freeze Zone uses a caramel to ice cream ratio of 666 / 888 which is equal to 0,75.
Their milkshakes have less caramel and more ice cream than Ari's perfect milkshake so Ari will think that Freeze Zone's milkshakes are not sweet enough.
I hope this answer helps.
